GOOD CLNICAL PRACTICES
FOR CLINICAL RESEARCH IN INDIA

 

FOREWORD

Clinical research is the key to the discovery of latest diagnostic methods and to develop modern drugs for treatment of diseases. Good Clinical Practices (GCP) is an ethical and scientific quality standard for designing, conducting and recording trials that involve the participation of human subjects. Compliance with this standard provides assurance to public that the rights, safety and well being of trial subjects are protected, consistent with the principles enshrined in the Declaration of Helsinki and ensures that clinical trial data are credible.

 

It has been widely recognized that India offers unique opportunities for conducting clinical trials in view of the large patient pool, well- trained and enthusiastic investigators and premiere medical institutes available in the country along with considerable low per patient trial cost, as compared to developed countries.

 

A need was, however, felt to develop our own Indian Guidelines to ensure uniform quality of clinical research throughout the country and to generate data for registration for new drugs before use in the Indian population. An Expert Committee set up by Central Drugs Standard Control Organisation (CDSCO) in consultation with clinical expert has formulated this GCP guideline for generation of clinical data on drugs.

 

The Drug Technical Advisory Board (DTAB), the highest technical body under D&C, Act, has endorsed adoption of this GCP guideline for streamlining the clinical studies in India.

 

I am confident that this guideline will be immensely useful to research institutions, investigators, institutional ethics committees and regulators in providing desired direction. The guideline would also be helpful to companies who may want to locate their clinical programme in the country.

Good Clinical Practice Guidelines

 

 

Introduction

 

The history of Good Clinical Practice (GCP) statute traces back to one of the oldest enduring traditions in the history of medicine: The Hippocratic Oath.  As the guiding ethical code it is primarily known for its edict to do no harm to the patient.  However, the complexities of modern medicine research necessitate a more elaborate set of guidelines that address a Physician’s ethical and scientific responsibilities such as obtaining informed consent or disclosing risk while involved in biomedical research.

 

Good Clinical Practice is a set of guidelines for biomedical studies which encompasses the design, conduct, termination, audit, analysis, reporting and documentation of the studies involving human subjects.  The fundamental tenet of GCP is that in research on man, the interest of science and society should never take precedence over considerations related to the well being of the study subject.  It aims to ensure that the studies are scientifically and ethically sound and that the clinical properties of the pharmaceutical substances under investigation are properly documented.   The guidelines seek to establish two cardinal principles: protection of the rights of human subjects and authenticity of biomedical data generated.

 

These guidelines have been evolved with consideration of WHO, ICH, USFDA and European GCP guidelines as well as the Ethical Guidelines for Biomedical research on Human Subjects issued by the Indian Council of Medical Research.  They should be followed for carrying out all biomedical research in India at all stages of drug development, whether prior or subsequent to product registration in India.

 

 


Definitions

 

Act

Wherever relevant, the Act means Drugs & Cosmetics Act 1940 (23 of 1940) and the Rules made thereunder.

 

Adverse Event (AE)

Any untoward medical occurrence (including a symptom / disease or an abnormal laboratory finding) during treatment with a pharmaceutical product in a patient or a human volunteer that does not necessarily have a relationship with the treatment being given. Also see Serious Adverse Event

 

Adverse Drug Reaction (ADR)

(a)   In case of approved pharmaceutical products:  A noxious and unintended response at doses normally used or tested in humans

(b)   In case of new unregistered pharmaceutical products (or those products which are not yet approved for the medical condition where they are being tested): A noxious and unintended response at any dose(s)

The phrase ADR differs from AE, in case of an ADR there appears to be a reasonable possibility that the adverse event is related with the medicinal product being studied.

In clinical trials, an untoward medical occurrence seemingly caused by overdosing, abuse / dependence and interactions with other medicinal products is also considered as an ADR.

Adverse drug reactions are type A (pharmacological) or type B (idiosyncratic). Type A reactions represent an augmentation of the pharmacological actions of a drug. They are dose-dependent and are, therefore, readily reversible on reducing the dose or withdrawing the drug. In contrast, type B adverse reactions are bizarre and cannot be predicted from the known pharmacology of the drug.

 

Audit of a Trial

A systematic verification of the study, carried out by persons not directly involved, such as:

(a)   Study related activities to determine consistency with the Protocol

(b)   Study data to ensure that there are no contradictions on Source Documents.  The audit should also compare data on the Source Documents with the interim or final report.  It should also aim to find out if practices were employed in the development of data that would impair their validity.

(c)   Compliance with the adopted Standard Operating Procedures (SOPs)

 

Blinding / Masking

A method of “control experimentation” in which one or more parties involved are not informed of the treatment being given.  Single blind refers to the study subject(s) being unaware, while Double blind refers to the study subject(s) and/or investigator(s), monitor, data analyst(s) are being unaware of the treatment assigned.

 

Case Record Form (CRF)

A document designed in consonance with the Protocol, to record data and other information on each trial subject.  The Case Record Form should be in such a form and format that allows accurate input, presentation, verification, audit and inspection of the recorded data.  A CRF may be in printed or electronic format.

 

Clinical Trial (Clinical Study)

A systematic study of pharmaceutical products on human subjects – (whether patients or non-patient volunteers) – in order to discover or verify the clinical, pharmacological (including pharmacodynamics / pharmacokinetics), and / or adverse effects, with the object of determining their safety and / or efficacy.

 

Human/Clinical Pharmacology trials (Phase I)

The objective of phase I of trials is to determine the maximum tolerated dose in humans; pharmacodynamic effect, adverse reactions, if any, with their nature and intensity; and pharmacokinetic behaviour of the drug as far as possible. These studies are often carried out in healthy adult volunteers using clinical, physiological and biochemical observations. At least 2 subjects should be used on each dose.

Phase I trials are usually carried out by investigators trained in clinical pharmacology and having the necessary facilities to closely observe and monitor the subjects. These may be carried out at one or two centres.

 

Exploratory trials (Phase II)

In phase II trials a limited number of patients are studied carefully to determine possible therapeutic uses, effective dose range and further evaluation of safety and pharmacokinetics. Normally 10-12 patients should be studied at each dose level. These studies are usually limited to 3-4 centres and carried out by clinicians specialized on the concerned therapeutic areas and having adequate facilities to perform the necessary investigations for efficacy and safety.

 

Confirmatory trials (Phase III)

The purpose of these trials is to obtain sufficient evidence about the efficacy and safety of the drug in a larger number of patients, generally in comparison with a standard drug and/or a placebo as appropriate. These trials may be carried out by clinicians in the concerned therapeutic areas, having facilities appropriate to the protocol. If the drug is already approved/marketed in other countries, phase III data should generally be obtained on at least 100 patients distributed over 3-4 centres primarily to confirm the efficacy and safety of the drug, in Indian patients when used as recommended in the product monograph for the claims made.

 

Data on ADRs observed during clinical use of the drug should be reported along with a report on its efficacy in the prescribed format. The selection of clinicians for such monitoring and supply of drug to them will need approval of the licensing authority under Rule 21 of the Act.

 

Phase IV

Studies performed after marketing of the pharmaceutical product. Trials in phase IV are carried out on the basis of the product characteristics on which the marketing authorization was granted and are normally in the form of post-marketing surveillance, assessment of therapeutic value, treatment strategies used and safety profile. Phase IV studies should use the same scientific and ethical standards as applied in pre-marketing studies.

After a product has been placed on the market, clinical trials designed to explore new indications, new methods of administration or new combinations, etc. are normally considered as trials for new pharmaceutical products.

 

Comparator Product

A pharmaceutical product (including placebo) used as a reference in a clinical trial.

 

Confidentiality

Maintenance of privacy of study subjects including their personal identity and all medical information, from individuals other than those prescribed in the Protocol.  Confidentiality also covers the prevention of disclosure of sponsor’s proprietary information to unauthorised persons.

2.4.             Ethical & Safety Considerations

2.4.1.                        Ethical Principles

            All research involving human subjects should be conducted in accordance with the ethical principles contained in the current revision of Declaration of Helsinki (see Appendix 1) and should respect three basic principles, namely justice, respect for persons, beneficence (to maximize benefits and to minimize harms and wrongs) and non malaficence (to do no harm) as defined by “Ethical Guidelines for Biomedical Research on Human Subjects” issued by the Indian Council of Medical Research and any other laws and regulations of the country, which ensure a greater protection for subjects.

 

            The following principles are to be followed:

a. Principles of essentiality whereby, the research entailing the use of human subjects is considered to be absolutely essential after a due consideration of all alternatives in the light of the existing knowledge in the proposed area of research and after the proposed research has been duly vetted and considered by an appropriate and responsible body of persons who are external to the particular research and who, after careful consideration, come to the conclusion that the said research is necessary for the advancement of knowledge and for the benefit of all members of the human species and for the ecological and environmental well being of the planet.

 

b. Principles of voluntariness, informed consent and community agreement whereby, Study Subjects are fully apprised of the Study and the impact and risk of such Study on the Study Subjects and others; and whereby the research subjects retain the right to abstain from further participation in the research irrespective of any legal or other obligation that may have been entered into by them or by someone on their behalf, subject to only minimal restitutive obligations of any advance consideration received and outstanding.

 

c. Principles of non-exploitation whereby as a general rule, research subjects are remunerated for their involvement in the research or experiment; and, irrespective of the social and economic condition or status, or literacy or educational levels attained by the research subjects kept fully apprised of all the dangers arising in and out of the research so that they can appreciate all the physical and psychological risks as well as moral implications of the research whether to themselves or others, including those yet to be born.

 

d. Principles of privacy and confidentiality whereby, the identity and records of the human subjects of the research or experiment are as far as possible kept confidential; and that no details about identity of said human subjects, which would result in the disclosure of their identity, are disclosed without valid scientific and legal reasons which may be essential for the purposes of therapeutics or other interventions, without the specific consent in writing of the human subject concerned, or someone authorised on their behalf; and after ensuring that the said human subject does not suffer from any form of hardship, discrimination or stigmatisation as a consequence of having participated in the research or experiment.

 

e. Principles of precaution and risk minimisation whereby due care and caution is taken at all stages of the research and experiment (from its inception as a research idea, its subsequent research design, the conduct of the research or experiment and its applicative use) to ensure that the research subject and those affected by it are put to the minimum risk, suffer from no irreversible adverse effects and, generally, benefit from and by the research or experiment.

 

f. Principles of professional competence whereby, the research is conducted at all times by competent and qualified persons, who act with total integrity and impartiality and who have been made aware of, and mindful of, the ethical considerations to be borne in mind in respect of such Study.

 

f.        Principles of accountability and transparency whereby, the research or experiment will be conducted in a fair, honest, impartial and transparent manner, after full disclosure is made by those associated with the Study of each aspect of their interest in the Study, and any conflict of interest that may exist; and whereby, subject to the principles of privacy and confidentiality and the rights of the researcher, full and complete records of the research inclusive of data and notes are retained for such reasonable period as may be prescribed or considered necessary for the purposes of post-research monitoring, evaluation of the research, conducting further research (whether by the initial researcher or otherwise) and in order to make such records available for scrutiny by the appropriate legal and administrative authority, if necessary.

 

h. Principles of the maximisation of the public interest and of distributive justice whereby, the research or experiment and its subsequent applicative use are conducted and used to benefit all human kind and not just those who are socially better off but also the least advantaged; and in particular, the research subject themselves.

 

i. Principles of institutional arrangements whereby, there shall be a duty on all persons connected with the research to ensure that all the procedures required to be complied with and all institutional arrangements required to be made in respect of the research and its subsequent use or application are duly made in a bonafide and transparent manner; and to take all appropriate steps to ensure that research reports, materials and data connected with the research are duly preserved and archived.

 

j. Principles of public domain whereby, the research and any further research, experimentation or evaluation in response to, and emanating from such research is brought into the public domain so that its results are generally made known through scientific and other publications subject to such rights as are available to the researcher and those associated with the research under the law in force at that time.

 

k. Principles of totality of responsibility whereby the professional and moral responsibility, for the due observance of all the principles, guidelines or prescriptions laid down generally or in respect of the research or experiment in question, devolves on all those directly or indirectly connected with the research or experiment including the researchers, those responsible for funding or contributing to the funding of the research, the institution or institutions where the research is conducted and the various persons, groups or undertakings who sponsor, use or derive benefit from the research, market the product (if any) or prescribe its use so that, inter alia, the effect of the research or experiment is duly monitored and constantly subject to review and remedial action at all stages of the research and experiment and its future use.

 

l. Principles of compliance whereby, there is a general and positive duty on all persons, conducting, associated or connected with any research entailing the use of a human subject to ensure that both the letter and the spirit of these guidelines, as well as any other norms, directions and guidelines which have been specifically laid down or prescribed and which are applicable for that area of research or experimentation, are scrupulously observed and duly complied with.

 

2.4.2.    Ethics Committee:

The sponsor and / or investigator should seek the opinion of an independent Ethics Committee regarding suitability of the Protocol, methods and documents to be used in recruitment of Subjects and obtaining their Informed Consent including adequacy of the information being provided to the Subjects. The Ethics Committees are entrusted not only with the initial view of the proposed research protocols prior to initiation of the projects but also have a continuing responsibility of regular monitoring for the compliance of the Ethics of the approved programmes till the same are completed. Such an ongoing review is in accordance with the Declaration of Helsinki and all the international guidelines for biomedical research

 

2.4.2.1            Basic Responsibilities

The basic responsibility of an IEC is to ensure a competent review of all ethical aspects of the project proposals received and execute the same free from any bias and influence that could affect their objectivity.

The IECs should specify in writing the authority under which the Committee is established, membership requirements, the terms of reference, the conditions of appointment, the offices and the quorum requirements. The responsibilities of an IEC can be defined as follows :

 

a.      To protect the dignity, rights and well being of the potential research participants.

b. To ensure that universal ethical values and international scientific standards are expressed in terms of local community values and customs.

c. To assist in the development and the education of a research community responsive to local health care requirements

 

2.4.2.2.          Composition

a. IEC should be multidisciplinary and multi-sectorial in composition. Independence and competence are the two hallmarks of an IEC.

 

                        b. The number of persons in an ethical committee be kept fairly small (5-7 members). It is generally accepted that a minimum of five persons is required to compose a quorum. There is no specific recommendation for a widely acceptable maximum number of persons but it should be kept in mind that too large a Committee will make it difficult in reaching consensus opinion. 12 to 15 is the maximum recommended number

 

c. The Chairperson of the Committee should preferably be from outside the Institution and not head of the same Institution to maintain the independence of the Committee. The Member Secretary who generally belongs to the same Institution should conduct the business of the Committee. Other members should be a mix of medical/non-medical, scientific and non-scientific persons including lay public to reflect the differed viewpoints. The composition may be as follows :-

1.      Chairperson

2.      1-2 basic medical scientists (preferably one pharmacologists).

3.      1-2 clinicians from various Institutes

4.      One legal expert or retired judge

5.      One social scientist / representative of non-governmental voluntary agency

6.      One philosopher / ethicist / theologian

7.      One lay person from the community

8.      Member Secretary

 

d. The ethical committee at any institution can have as its members, individuals from other institutions or communities if required. There should be adequate representation of age, gender, community; etc. in the Committee to safeguard the interests and welfare of all sections of the community/society. Members should be aware of local, social and cultural norms, as this is the most important social control mechanism. If required subject experts could be invited to offer their views.

 

2.4.2.3. Terms of Reference

The IEC members should be made aware of their role and responsibilities as committee members. Any change in the regulatory requirements should be brought to their attention and they should be kept abreast of all national and international developments in this regard. The Terms of References should also include a statement on Terms of Appointment with reference to the duration of the term of membership, the policy for removal, replacement and resignation procedure etc. Each Committee should have its own operating procedures available with each member.

 

2.4.2.4.            Review Procedures

The Ethics Committee should review every research proposal on human subjects. It should ensure that a scientific evaluation has been completed before ethical review is taken up. The Committee should evaluate the possible risks to the subjects with proper justification, the expected benefits and adequacy of documentation for ensuring privacy, confidentiality and justice issues. The ethical review should be done through formal meetings and should not resort to decisions through circulation of proposals.

 

2.4.2.5.            Submission of Application

The researcher should submit an appropriate application to the IEC in a prescribed format along with the study protocol at least three weeks in advance. The protocol should include the following:

1.      Clear research objectives and rationale for undertaking the investigation in human subjects in the light of existing knowledge.

2.      Recent curriculum vitae of the Investigators indicating qualification and experience.

3.      Subject recruitment procedures.

4.      Inclusion and exclusion criteria for entry of subjects in the study.

5.      Precise description of methodology of the proposed research, including intended dosages and routes of administration of drugs, planned duration of treatment and details of invasive procedures if any.

6.      A description of plans to withdraw or withhold standard therapies in the course of research.

7.      The plans for statistical analysis of the study.

8.      Procedure for seeking and obtaining informed consent with sample of patient information sheet and informed consent forms in English and vernacular languages.

9.      Safety of proposed intervention and any drug or vaccine to be tested, including results of relevant laboratory and animal research.

10. For research carrying more than minimal risk, an account of plans to provide medical therapy for such risk or injury or toxicity due to over-dosage should be included.

11. Proposed compensation and reimbursement of incidental expenses.

12. Storage and maintenance of all data collected during the trial.

13. Plans for publication of results - positive or negative - while maintaining the privacy and confidentiality of the study participants.

14. A statement on probable ethical issues and steps taken to tackle the same.

15. All other relevant documents related to the study protocol including regulatory clearances.

16. Agreement to comply with national and international GCP protocols for clinical trials.

17. Details of Funding agency / Sponsors and fund allocation for the proposed work.

 

 

 

2.4.2.6.            Decision Making Process

The IEC should be able to provide complete and adequate review of the research proposals submitted to them It should meet periodically at frequent intervals to review new proposals, evaluate annual progress of ongoing ones and assess final reports of all research activities involving human beings through a previously scheduled agenda, amended wherever appropriate.

1.      The decision must be taken by a broad consensus after the quorum requirements are fulfilled to recommend / reject / suggest modification for a repeat review or advice appropriate steps. The Member Secretary should communicate the decision in writing.

2.      A member must voluntarily withdraw from the IEC while making a decision on an application which evokes a conflict of interest which should be indicated in writing to the chairperson prior to the review and should be recorded so in the minutes.

3.      If one of the members has her/his own proposal for review, then the member should not participate when the project is discussed.

4.      A negative decision should always be supported by clearly defined reasons.

5.      An IEC may decide to reverse its positive decision on a study in the event of receiving information that may adversely affect the benefit/risk ratio.

6.      The discontinuation of a trial should be ordered if the IEC finds that the goals of the trial have already been achieved midway or unequivocal results are obtained.

7.      In case of premature termination of study, notification should include the reasons for termination along with the summary of results conducted till date.

8.      The following circumstances require the matter to be brought to the attention of IEC :

a.      any amendment to the protocol form the originally approved protocol with proper justification;

b.      serious and unexpected adverse events and remedial steps taken to tackle them;

c.      any new information that may influence the conduct of the study.

9.      If necessary, the applicant/investigator may be invited to present the protocol or offer clarifications in the meeting. Representative of the patient groups or interest groups can be invited during deliberations to offer their viewpoint.

10. Subject experts may be invited to offer their views, but should not take part in the decision making process. However, her/his opinion must be recorded.

11. Meetings are to be minuted which should be approved and signed by the Chairperson.

 

2.4.2.7.            Interim Review

The IEC should decide and record the special circumstances and the mechanism when an interim review can be resorted-to instead of waiting for the scheduled time of the meeting. However, decisions taken should be brought to the notice of the main committee. This can be done for the following reasons:

i)        re-examination of a proposal already examined by the IEC;

ii)      research study of a minor nature such as examination of case records etc.;

iii)    an urgent proposal of national interest.

 

2.4.2.8.            Record Keeping

All documentation and communication of an IEC are to be dated, filed and preserved according to written procedures. Strict confidentiality is to be maintained during access and retrieval procedures. Records should be maintained for the following :

i.        the Constitution and  composition of the IEC;

ii.      the curriculum vitae of all IEC members;

iii.    standing operating procedures of the IEC;

iv.     national and international guidelines;

v.       copies of the Protocol, data collection formats, CRFs, investigational brochures etc. submitted for review;

vi.     all correspondence with IEC members and investigators regarding application, decision and follow up;

vii.   agenda of all IEC meetings;

viii. minutes of all IEC meetings with signature of the Chairperson;

ix.     copies of decisions communicated to the applicants;

x.       record of all notification issued for premature termination of a study with a summary of the reasons;

xi.     final report of the study including microfilms, CDs and Video-recordings.

 

It is recommended that all records must be safely maintained after the completion / termination of the study for at least a period of 5 years if it is not possible to maintain the same permanently.

 

2.4.2.9. Special Considerations

While all the above requirements are applicable to biomedical research as a whole irrespective of the speciality of research, there are certain specific concerns pertaining to specialised areas of research which require additional safe guards / protection and specific considerations for the IEC to take note of. Examples of such instances are research involving children, pregnant and lactating women, vulnerable subjects and those with diminished autonomy besides issues pertaining to commercialisation of research and international collaboration. The observations and suggestions of IEC should be given in writing in unambiguous terms in such instances.

 

2.4.3.                        Informed Consent Process

2.4.3.1. Informed Consent of Subject :

Prior to the beginning of the Study the Investigator(s) should obtain the Ethics Committee’s approval for the written informed consent form and all information being provided to the Subjects and / or their legal representatives or guardians as well as an impartial witness.

 

      None of the oral and written information concerning the Study, including the written informed consent form, should contain any language that causes the Subject(s) or their legal representatives or guardians to waive or to appear to waive their legal rights, or that releases or appears to release the Investigator, the Institution, the Sponsor or their representatives from their liabilities for any negligence.

 

      The information should be given to the Subjects and / or their legal representatives or guardians in a language and at a level of complexity that is understandable to the Subject(s) in both written and oral form, whenever possible.

     

      Subjects, their legal representatives or guardians should be given ample opportunity and time to enquire about the details of the Study and all questions answered to their satisfaction. 

The Investigator(s), Sponsor or staff of the Institution should not coerce or unduly influence a potential Subject to participate or to continue to participate in the Study. Careful consideration should be given to ensuring the freedom of consent obtained from members of a group with a hierarchical structure- such as medical, pharmacy and nursing students, subordinate hospital and laboratory personnel, employees of the pharmaceutical industry, and members of the armed forces. Persons with incurable diseases, in nursing homes, in detention, unemployed or impoverished, in emergency rooms, homeless persons, nomads, refugees and any ethnic or racial minority groups should be considered as vulnerable population whose mode of consent should be carefully considered and approved by the Ethics Committee.

 

Prior to the Subject’s participation in the Study the written Informed Consent form should be signed and personally dated by

1.      (i) The Subject or (ii) if the Subject is incapable of giving an Informed Consent for example children, unconscious or suffering from severe mental illness or disability, by the Subject’s legal representative or guardian or (iii) if the Subject and his legal representative or guardian is unable to read / write,

2.      An impartial witness who should be present during the entire informed consent discussion

3.      The Investigator

 

By signing the consent form the witness attests that the information in the consent form and any other written information was accurately explained to, and apparently understood by, the Subject or the Subject’s legal representative or the guardian, and that informed consent was freely given by the Subject or the Subject’s legal representative or the guardian.

 

The Subject’s legal representative or guardian (if the subject is incapable of giving an Informed Consent for example children, unconscious or suffering from severe mental illness or disability), the inclusion of such patients in the study may be acceptable if the ethics committee is in principle, in agreement, and if the investigator thinks that the participation will promote the welfare and interest of the Subject.  The agreement of a legal representative or the guardian that participation will promote the welfare and interest of the Subject should also be recorded with dated signature.  If, however, neither the signed Informed Consent nor the witnessed signed verbal consent are possible – this fact must be documented stating reasons by the Investigator and also brought to the knowledge of Ethics Committee without any delay.

 

2.4.3.2. Essential information for prospective research on subjects :  Before requesting an individual's consent to participate in research, the investigator must provide the individual  with the following information in the language he or she is able to understand which should not only be scientifically accurate but should also be sensitive to their social and cultural context :

i.        the aims and methods of the research;

ii.      the expected duration of the subject participation;

iii.    the benefits that might reasonably be expected as an outcome of research to the subject or to others;

iv.     any alternative procedures or courses of treatment that might be as advantageous to the subject as the procedure or treatment to which she/he is being subjected;

v.       any foreseeable risk or discomfort to the subject resulting from participation in the study;

vi.     right to prevent use of his/her biological sample (DNA, cell-line, etc.) at any time during the conduct of the research;

vii.   the extent to which confidentiality of records could be able to safeguard, confidentiality and the anticipated consequences of breach of confidentiality;

viii. free treatment for research related injury by the investigator / institution;

ix.     compensation of subjects for disability or death resulting from such injury;

x.       freedom of individual / family to participate and to withdraw from research any time without penalty or loss of benefits which the subject would otherwise be entitled to;

xi.     the identity of the research teams and contact persons with address and phone numbers;

xii.   foreseeable extent of information on possible current and future uses of the biological material and of the data to be generated from the research and if the material is likely to be used for secondary purposes or would be shared with others, clear mention of the same;

xiii. risk of discovery of biologically sensitive information;

xiv. publication, if any, including photographs and pedigree charts.

 

The quality of the consent of certain social groups requires careful consideration as their agreement to volunteer may be unduly influenced by the Investigator.

 

2.4.3.3.          Informed Consent in Non-Therapeutic Study :

In case of a Non-Therapeutic Study the consent must always be given by the subject.  Non-Therapeutic Studies may be conducted in subjects with consent of a legal representative or guardian provided all of the following conditions are fulfilled:

1.      The objective of the Study can not be met by means of a trial in Subject(s) who can personally give the informed consent

2.      The foreseeable risks to the Subject(s) are low

3.      Ethics Committee’s written approval is expressly sought on the inclusion of such Subject(s)

 

            2.4.4. Essential Information on Confidentiality for Prospective Research Subjects

Safeguarding confidentiality - The investigator must safeguard the confidentiality of research data, which might lead to the identification of the individual subjects. Data of individual subjects can be disclosed only in a court of law under the orders of the presiding judge or in some cases may be required to communicate to drug registration authority or to health authority. Therefore, the limitations in maintaining the confidentiality of data should be anticipated and assessed.

 

            2.4.5.            Compensation for Participation

Subjects may be paid for the inconvenience and time present, and should be reimbursed for expenses incurred, in connection with their participation in research. They may also receive free medical services. However, payments should not be so large or the medical services so extensive as to induce prospective subjects to consent to participate in research against their better judgement (inducement). All payments, reimbursement and medical services to be provided to research subjects should be approved by the IEC. Care should be taken :

 

i.        when a guardian is asked to give consent on behalf of an incompetent person, no remuneration should be offered except a refund of out of pocket expenses;

ii.      when a subject is withdrawn from research for medical reasons related to the study the subject should get the benefit for full participation;

iii.    when a subject withdraws for any other reasons he/she should be paid in proportion to the amount of participation.

 

Academic institutions conducting research in alliance with industries / commercial companies require a strong review to probe possible conflicts of interest between scientific responsibilities of researchers and business interests (e.g. ownership or part-ownership of a company developing a new product). In cases where the review board/committee determines that a conflict of interest may damage the scientific integrity of a project or cause harm to research participants, the board should advise accordingly. Institutions need self-regulatory processes to monitor, prevent and resolve such conflicts of interest. Prospective participants in research should also be informed of the sponsorship of research, so that they can be aware of the potential for conflicts of interest and commercial aspects of the research. Undue inducement through compensation for individual participants, families and populations should be prohibited. This prohibition however, does not include agreements with individuals, families, groups, communities or populations that foresee technology transfer, local training, joint ventures, provision of health care reimbursement, costs of travel and loss of wages and the possible use of a percentage of any royalties for humanitarian purposes.

 

2.4.6. Selection of Special Groups As Research Subject

2.4.6.1.          Pregnant or nursing women :

Pregnant or nursing women should in no circumstances be the subject of any research unless the research carries no more than minimal risk to the fetus or nursing infant and the object of the research is to obtain new knowledge about the foetus, pregnancy and lactation. As a general rule, pregnant or nursing women should not be subjects of any clinical trial except such trials as are designed to protect or advance the health of pregnant or nursing women or foetuses or nursing infants, and for which women who are not pregnant or nursing would not be suitable subjects.

a.      The justification of participation of these women in clinical trials would be that they should not be deprived arbitrarily of the opportunity to benefit from investigations, drugs, vaccines or other agents that promise therapeutic or preventive benefits. Example of such trials are, to test the efficacy and safety of a drug for reducing perinatal transmission of HIV infection from mother to child, trials for detecting fetal abnormalities and for conditions associated with or aggravated by pregnancy etc. Women should not be encouraged to discontinue nursing for the sake of participation in research and in case she decides to do so, harm of cessation of breast feeding to the nursing child should be properly assessed except in those studies where breast feeding is harmful to the infant.

b.      Research related to termination of pregnancy: Pregnant women who desire to undergo Medical Termination of Pregnancy (MTP) could be made subjects for such research as per The Medical Termination of Pregnancy Act, GOI, 1971.

c.      Research related to pre-natal diagnostic techniques: In pregnant women such research should be limited to detect the foetal abnormalities or genetic disorders as per the Prenatal Diagnostic Techniques (Regulation and Prevention of Misuse) Act, GOI, 1994 and not for sex determination of the foetus.

 

2.4.6.2.          Children:

Before undertaking trial in children the investigator must ensure that -

a.      children will not be involved in research that could be carried out equally well with adults;

b.      the purpose of the research is to obtain knowledge relevant to health needs of children. For clinical evaluation of a new drug the study in children should always be carried out after the phase III clinical trials in adults. It can be studied earlier only if the drug has a therapeutic value in a primary disease of the children;

c.      a parent or legal guardian of each child has given proxy consent;

d.      the assent of the child should be obtained to the extent of the child's capabilities such as in the case of mature minors, adolescents etc;

e.      research should be conducted in settings in which the child and parent can obtain adequate medical and psychological support;

f.        interventions intended to provide direct diagnostic, therapeutic or preventive benefit for the individual child subject must be justified in relation to anticipated risks involved in the study and anticipated benefits to society;

g.      the child's refusal to participate in research must always be respected unless there is no medically acceptable alternative to the therapy provided/tested, provided the consent has been obtained from parents/guardian;

h.      interventions that are intended to provide therapeutic benefit are likely to be at least as advantageous to the individual child subject as any available alternative interventions;

i.        the risk presented by interventions not intended to benefit the individual child subject is low when compared to the importance of the knowledge that is to be gained.

 

2.4.6.3.          Vulnerable groups :

Effort may be made to ensure that individuals or communities invited for research be selected in such a way that the burdens and benefits of the research are equally distributed.

a.      research on genetics should not lead to racial inequalities;

b.      persons who are economically or socially disadvantaged should not be used to benefit those who are better off than them;

c.      rights and welfare of mentally challenged and mentally differently able persons who are incapable of giving informed consent or those with behavioral disorders must be protected.

d.      Adequate justification is required for the involvement of subjects such as prisoners, students, subordinates, employees, service personnel etc. who have reduced autonomy as research subjects.

 

            2.4.7.            Compensation for Accidental Injury

Research subjects who suffer physical injury as a result of their participation in the Clinical Trial are entitled to financial or other assistance to compensate them equitably for any temporary or permanent impairment or disability subject to confirmation from IEC In case of death, their dependents are entitled to material compensation.

 

2.4.7.1.          Obligation of the sponsor to pay :

                        The sponsor whether a pharmaceutical company, a government, or an institution, should agree, before the research begins, to provide compensation for any  serious sphysical or mental injury for which subjects are entitled to compensation or agree to provide insurance coverage for an unforeseen injury whenever possible.

This information should be accurate and adequate to justify the nature, scale and the duration of the Study.  In addition, the Sponsor must bring any relevant new information arising during the period of Study to the attention of the Investigator(s) as well as the Ethics Committee.

 

3.1.9.            Supply, storage and handling of Pharmaceutical Products

The Sponsor is responsible for supplying the Investigational Product’s, including Comparator(s) and Placebo if applicable.  The Products should be manufactured in accordance with the principles of GMPs and they should be suitably packaged in the manner that will protect the product from deterioration and safeguard blinding procedures (if applicable) and should be affixed with appropriate investigational labelling.

 

The Sponsor should determine the Investigational Product’s acceptable storage conditions, reconstitution procedures and devices for product infusions if any, and communicate them in writing to all involved parties, besides stating them on the Product labels where ever possible.

 

In case any significant formulation changes are made in the Investigational Product during the course of the Study - the results of any additional studies of the new formulation (e.g. stability, bioavailability, dissolution rate) should be provided to the involved parties to enable them to determine their effects on the pharmacokinetic profile of the Product prior to the use in the Study.

The Sponsor should not supply an Investigator / Institution with the Product until the Sponsor obtains all required documentation (e.g. approval / favourable opinion from Ethics Committee and Regulatory Authorities).

 

The Sponsor should document procedures and lay down responsibilities for

a.      adequate and safe receipt, handling, storage, dispensing of the Product

b.      retrieval of unused Product from the Subjects and

c.      return of unused Product to the Sponsor (or its alternative disposal procedure).

 

Sponsor should maintain records for retrieval of Product (e.g. retrieval after study completion, expired product retrieval etc.).

 

Sponsor should also maintain records of the quantities of Investigational Product with proper batch numbers.  The Sponsor should ensure that the Investigator is able to establish a system within his / her Institution for proper management of the Products as per the procedures.

 

The Sponsor should maintain sufficient samples from each batch and keep the record of their analyses and characteristics for reference, so that if necessary an independent laboratory may be able to recheck the same.

 

3.1.10.            Safety Information:

3.1.13. Monitoring

Although an extensively written guidance can assure appropriate conduct of the study, the sponsor should ensure that the studies are adequately monitored.  The determination of the extent and the nature of monitoring should be based on considerations such as objective, purpose, design, complexity, blinding, size and endpoints of the study.  The sponsor must appoint adequately trained monitors or CRO to supervise an ongoing study.

 

3.1.14. Audit:

Sponsor should perform an audit as a part of QA system.  This audit should be conducted with the purpose of being independent and separate from routine monitoring or quality control functions.  Audit should evaluate the study conduct and compliance with the protocol, SOPs, GCPs and applicable regulatory requirements. For the purpose of carrying out the audit – the sponsor may appoint individuals qualified by training and experience to conduct audits.  The Auditors should be independent of the parties involved in the study and their qualifications should be documented. 

 

The Sponsor should ensure that the auditing is conducted in accordance with the Sponsor’s SOPs on what to audit, how to audit, the frequency of audit and the form & content of audit reports.  Auditors should document their observations which should be archived by the Sponsors and made available to the Regulatory Authorities when called for.

 

Sponsor should initiate prompt action in case it is discovered that any party involved has not entirely complied with the GCP, SOPs, Protocol and / or any applicable regulatory requirements.  If monitoring / auditing identifies serious and / or persistent non-compliance - the Sponsor should terminate the defaulting party’s participation in the study and promptly notify to the regulatory authority. 

 

3.1.15. Multicentre Studies

Since multicentre studies are conducted simultaneously by several investigators at different institutions following the same protocol, the sponsor should make special administrative arrangements for their conduct. These administrative arrangements should provide adequate assurance that the study will be planned and conducted according to GCPs. 

 

The various tasks that may need special consideration include responsibility for commencement and overall performance of the study, supervision of the data, monitoring of the ADRs / AEs and various other policy matters. The functions, responsibilities and mandate of any special committee(s) set up or person(s) should be described in the study protocol, along with the procedure for their nomination.

 

A co-ordinating committee may be set up or a co-ordinator appointed with responsibility for the control of practical performance and progress of the study and maintaining contact with the regulatory authorities and the ethics committee(s).

 

Ideally, the studies should begin and end simultaneously at all institutions.

 

The sponsor should make arrangements to facilitate the communication between investigators at various sites.  All investigators and other specialists should be given the training to follow the same protocol and systems. The sponsor should obtain written acceptance of the protocol and its annexes from each of the investigator and institution involved.

 

The CRFs should be so designed as to record the required data at all multicentre sites.  For those investigators who are collecting additional data, supplemental CRFs should be provided to record the additional data.

 

Before initiation of multi-centre studies the sponsor should carefully define and document the following:

a.      ethics committee(s), and the number of ethics committees to be consulted

b.      role and responsibilities of the co-ordinating investigators

c.      role and responsibilities of the CRO

d.      randomisation procedure

e.      standardisation and validation of methods of evaluation and analyses of laboratory and diagnostic data at various centres

f.        structure and function of a centralised data management set-up

 

3.1.16. Premature Termination or Suspension of a Study

In case the sponsor chooses to or is required to terminate prematurely or suspend the study, then the sponsor should notify the investigator(s), institution(s), the ethics committee and the regulatory authorities accordingly.  The notification should document the reason(s) for the termination or suspension by the sponsor or by the investigator / institution.

 

3.1.17. Role of Foreign Sponsor

            If the sponsor is a foreign company, organisation or person(s) – it shall appoint a local representative or CRO to fulfil the appropriate local responsibilities as governed by the national regulations.  The Sponsor may transfer any or all of the Sponsor’s study related duties and functions to a CRO but the ultimate responsibility for the quality and the integrity of the Study Data shall always reside with the Sponsor.  Any Study related duty, function or responsibility transferred to and assumed by a local representative or a CRO should be specified in writing.  Any Study related duties, functions or responsibilities not specifically transferred to and assumed by a CRO or a local representative shall be deemed to have been retained by the Sponsor. The sponsor should utilise the services of qualified individuals e.g. bio-statisticians, clinical pharmacologists, and physicians, as appropriate, throughout all stages of the study process, from designing the protocol and CRFs and planning the analyses to analysing and preparing interim and final clinical study reports.

Although a subject is not obliged to give reason(s) for withdrawing prematurely from a study, the investigator should make a reasonable effort to ascertain the reason(s) while fully respecting the subject’s rights.

 

3.3.3.    Monitoring and Auditing of Records

The investigator / institution shall allow monitoring and auditing of the records, procedures and facilities, by the sponsor, the ethics committee, CRO or their authorised representative(s) or by the appropriate regulatory authority.  The investigator should maintain a list of appropriately qualified person(s) to whom the investigator has delegated study-related duties.

 

            Investigator should ensure that all persons involved in the study are adequately informed about the protocol, SOPs, the investigational product(s) and their study related duties and functions.

 

3.3.4. Communication with Ethics Committee

Before initiating a study the investigator / institution must ensure that the proposed study has been reviewed and accepted in writing by the relevant ethics committee(s) for the protocol, written informed consent form, subject recruitment procedures (e.g. advertisements) and any written / verbal information to be provided to the subjects.

The investigator should promptly report to the ethics committee, the monitor and the sponsor:

1.      deviations from or changes of, the protocol to eliminate immediate hazards to the subjects

2.      changes that increase the risk to subject(s) and / or affecting significantly the conduct of the study

3.      all adverse drug reactions and adverse events that are serious and / or unexpected

4.      new information that may adversely affect safety of the subjects or the conduct of the study

5.      for reported deaths the investigator should supply any additional information e.g. autopsy reports and terminal medical reports.

 

3.3.5.            Compliance with the protocol

The investigator / institution must agree and sign the protocol and / or another legally acceptable document with the sponsor, mentioning the agreement with the protocol, and confirm in writing that he / she has read and understood the protocol, GCPs and SOPs and will work as stipulated in them.

 

The investigator may implement a deviation from, or change of protocol to eliminate an immediate hazard(s) to study subjects without prior ethics committee approval / favourable opinion. The implemented deviation or change, the reasons for it and if appropriate the proposed protocol amendment(s) should be submitted by the investigator to the ethics committee (for review and approval / favourable opinion), to the sponsor (for agreement) and if required to the regulatory authority(ies).

 

The investigator or person designated by him/her should document and explain any deviation from the approved protocol.  The Investigator should follow the study randomisation procedure, if any, and should ensure that the randomisation code is broken only in accordance with the Protocol.  If the study is blinded, the Investigator should promptly document and explain to the Sponsor any premature un-blinding e.g. accidental un-blinding, un-blinding due to serious adverse event) of the Investigational Product(s).

 

3.3.6. Investigational Product(s)

Investigator has the primary responsibility for investigational product(s) accountability at the study site(s). Investigator should maintain records of the product’s delivery to the study site, the inventory at the site, the use by each subject, and the return to the sponsor or the alternative disposal of the unused product(s).  These records should include dates, quantities, batch / serial numbers, expiry dates if applicable, and the unique code number assigned to the investigational product packs and study subjects.  Investigator should maintain records that describe that the subjects were provided the dosage specified by the protocol and reconcile all investigational products received from the sponsor.  Investigator should ensure that the product(s) are stored under specified conditions and are used only in accordance with the approved protocol.

 

The investigator should assign some or all of his / her duties for investigational product’s accountability at the study site(s) to his subordinate who is under the supervision of the investigator / institution.  The investigator or subordinate should explain the correct use of the product(s) to each subject and should check at intervals appropriate for the study that each subject is following the instructions properly.  The person who carries them out should document such periodic checks.

 

3.3.7.            Selection and recruitment of study subjects:

The investigator is responsible for ensuring the unbiased selection of an adequate number of suitable subjects according to the protocol.  It may be necessary to secure the co-operation of other physicians in order to obtain a sufficient number of subjects.  In order to assess the probability of an adequate recruitment rate for subjects for the study it may be useful to determine prospectively or review retrospectively the availability of the subjects.  Investigator should check whether the subject(s) so identified could be included in the study according to the protocol.  The investigator should keep a confidential list of names of all Study Subjects allocated to each study.   This list facilitates the investigator / institution to reveal identity of the subject(s) in case of need and also serve as a proof of Subject’s existence.  The investigator / institution shall also maintain a Subjects’ screening log to document identification of Subjects who enter pre-study screening.   A Subject’s enrolment log shall also be maintained to document chronological enrolment of Subjects in a particular Study.

 

The Investigator is responsible for giving adequate information to subjects about the trial in accordance with the GCP. The nature of the investigational product and the stage of development and the complexity of the study should be considered in determining the nature and extent of the information that should be provided.

 

Obligations of investigators regarding informed consent: The investigator has the duty to -

1.      Communicate to prospective subjects all the information necessary for informed consent. There should not be any restriction on subject's right to ask any questions related to the study as any restriction on this undermines the validity of informed consent.

2.      Exclude the possibility of unjustified deception, undue influence and intimidation. Deception of the subject is not permissible However, sometimes information can be withheld till the completion of study, if such information would jeopardize the validity of research.

3.      Seek consent only after the prospective subject is adequately informed. Investigator should not give any unjustifiable subject's decision to participate in the study.

4.      As a general rule obtain from each prospective subject a signed form as an evidence of informed consent (written informed consent) preferably witnessed by a person not related to the trial, and in case of incompetence to do so, a legal guardian or other duly authorised representative.

5.      Renew the informed consent of each subject, if there are material changes in the conditions or procedures of the research or new information becomes available during the ongoing trial.

6.      Not use intimidation in any form which invalidates informed consent. The investigator must assure prospective subjects that their decision to participate or not will not affect the patient-clinician relationship or any other benefits to which they are entitled.

 

As part of the information provided to the Subject, the Investigator should supply subjects with, and encourage them to carry with them, information about their participation in the trial and information about contact persons who can assist in an emergency situation.

 

3.3.8.            Records/Reports

The Investigator should ensure the accuracy, completeness, legibility, and timeliness of the data reported to the sponsor in the CRFs and in all required reports. Data reported on the CRF, that are derived from source documents, should be consistent with the source documents or the discrepancies should be explained.

 

Any change or correction to the CRF should be dated, signed and explained (if necessary) and should not obscure the original entry (i.e. an audit trail should be maintained); this applies to both written and electronic changes or corrections.

 

Sponsor should provide guidelines to investigators and / or the investigator’s designated representatives on making such corrections and should have written procedures to assure that changes in CRFs are documented and endorsed by the Investigator. The Investigator should retain records of the changes and corrections.

 

Progress Reports

The investigator should submit the written summaries of the study status at the periodicity specified in the protocol to the person(s) / organisation(s) to whom the investigator is reporting.  All reportings made by the investigator should identify the subjects by unique code numbers assigned to the study subjects rather than by the subjects’ name(s), personal identification number(s) and / or addresses.

 

Termination and final report:

In case the investigator and sponsor agree to prematurely terminate or suspend the study for any reason, the investigator / institution should promptly inform the study Subjects, the Ethics Committee as well as the Regulatory Authorities. The investigators should also ensure appropriate therapy and follow-up for the subjects.

 

However, if the investigator or the sponsor or the ethics committee decide to terminate or suspend the study without prior agreement of all parties concerned then the party initiating the suspension / termination should promptly inform all the concerned parties about such suspension / termination and suspension along with a detailed written explanation for such termination / suspension.

 

The Investigator should maintain documents as specified in the essential documents’ list and take measures to prevent accidental or premature destruction.

 

The study can be closed only when the Investigator (or the Monitor or CRO – if this responsibility has been delegated to them) has reviewed both Investigator / Institution and Sponsor files and confirm that all necessary documents are in the appropriate files.

 

The completion of the study should be informed by the investigator to the institution, the sponsor and the ethics committee.  The investigator should sign and forward the data (CRFs, results and interpretations, analyses and reports, of the study from his / her centre to the sponsor and the ethics committee.  Collaborative investigators and those responsible for the analyses (including statistical analyses) and the interpretation of the results must also sign the relevant portions of the study report. Investigator should submit his signed and dated final report to the institution, the ethics committee and the sponsor verifying the responsibility for the validity of data.

 

In case of a multi-centre study – the signature of the co-ordinating investigator may suffice if agreed in the protocol.

In case the investigator is the sponsor then he / she assumes the responsibilities of both the functionaries.

 

The investigator should familiarise himself / herself with the various other responsibilities assigned to him/her under the protocol and ensure that they are carried out as expected.

 


Record Keeping and Data Handling

 

 

The basic concept of record-keeping and handling of data is to record, store, transfer, and where necessary convert efficiently and accurately the information collected on the trial subject(s) into data that can be used to compile the Study Report.

 

4.1.           Documentation

All steps involved in data management should be documented in order to allow step-by-step retrospective assessment of data quality and study performance for the purpose of audit. Following the SOPs facilitates documentation.

Documentation SOPs should include details of checklists and forms giving details of actions taken, dates and the individuals responsible etc. 

 

4.2.           Corrections

All corrections in the CRFs or any other study related documents should be made in a way that does not obscure the original entry.  The correct data should be inserted with the reason for the correction if such a reason is not obvious.  The corrections should carry the date and initials of the Investigator or the authorised person.

 

4.3.           Electronic Data Processing

For electronic data processing only authorised person should be allowed to enter or modify the data in the computer and there should be a recorded trail of the changes and deletions made.  A security system should be set-up to prevent unauthorised access to the data.  If data is altered during processing the alteration must be documented and the system should be validated.  The systems should be designed to permit data changes in such a way that the data changes are documented and there is no deletion of data once it has been entered. A list of authorised persons who can make changes in the computer system should be maintained.  Adequate backup of the data should be maintained.

 

4.4.           Validation of Electronic Data Processing Systems

If trial data are entered directly into the computer there must always be an adequate safeguard to ensure validation including a signed and dated printout and backup records.  Computerised systems – hardware as well as software - should be validated and a detailed description of their use be produced and kept up-to-date. 

 

4.5.           Language

All written documents, information and other material used in the Study should be in a language that is clearly understood by all concerned (i.e. the Subjects, paramedical staff, Monitors etc.)

 

4.6.           Responsibilities of the Investigator

Investigator should ensure that the observations and findings are recorded correctly and completely in the CRFs and signed by the responsible person(s) designated in the Protocol. 

 

Laboratory values with normal reference ranges should always be recorded on a CRF or enclosed with the CRF.  Values outside the clinically accepted reference range or values that differ importantly from previous values must be evaluated and commented upon by the Investigator.  Data other than that requested by the Protocol may appear on the CRF clearly marked as the additional findings and their significance described by the investigator.  Units of measurement must always be stated and transformation of units must always be indicated and documented.

 

In the medical records of the patient(s) it should be clearly indicated that the individual is participating in a clinical trial.

 

4.8.            Responsibilities of the Sponsor and the Monitor

The sponsor must ensure that electronic data processing system conforms to the certain documented requirements for completeness, accuracy, reliability and consistent intended performance (i.e. validation).    The Sponsor must maintain SOPs for using these systems.  The Monitor should take adequate measures to ensure that no data is overlooked.  If the computer system automatically assigns any missing values – the fact should be clearly documented. 

 

Sponsor should safeguard the blinding, if any, particularly during data entry and processing.  The Sponsor should use an explicit Subject identification code that allows identification of all the data reported for each Subject.  Ownership of the data and any transfer of the ownership of data should be documented and intimated to the concerned party(ies). 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Quality Assurance

 

The Sponsor is responsible for the implementation of a system of Quality Assurance in order to ensure that the Study is performed and the data is generated, recorded and reported in compliance with the Protocol, GCP and other applicable requirements.  Documented Standard Operating Procedures are a prerequisite for quality assurance.

 

All observations and findings should be verifiable, for the credibility of the data and to assure that the conclusions presented are correctly derived from the Raw Data. Verification processes must therefore be specified and justified. 

 

Statistically controlled sampling may be an acceptable method of data verification in each Study.  Quality control must be applied to each stage of data handling to ensure that all data are reliable and have processed correctly.

 

Sponsor’s audits should be conducted by persons independent of those responsible for the Study. Investigational sites, facilities, all data and documentation should be available for inspection and audit by the Sponsor’s auditor as well as by the Regulatory Authority(ies).

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Statistics

 

6.1.           Role of a Biostatistician

Involvement of a appropriately qualified and experienced statistician is necessary in the planning stage as well as throughout the Study.  The Bio-statistician’s should make a statistical model to help the Sponsor, CRO and / or the Investigator in writing the Protocol.  The number of Subjects to be included in the study is determined in relation to the statistical model on which the Protocol is based.

 

6.2.           Study Design:

The scientific integrity of a Clinical Study and the credibility of its report depends on the design of the Study.  In comparative studies the Protocol should describe:

1.      an “a priori” rationale for the target difference between treatments that the Study is being designed to detect, and the power to detect that difference, taking into account clinical and scientific information and professional judgment on the clinical significance of statistical differences.

2.      measures taken to avoid bias, particularly methods of Randomisation.

 

6.2.1.            Randomisation and blinding:

The key idea of a clinical trial is to compare groups of patients who differ only with respect to their treatment.  If the groups differ in some other way then the comparison of treatment gets biased.  Randomisation, as one of the fundamental principles of experimental design, it deals with the possible bias at the treatment allocation. It ensures that the allocation of treatment to human subjects is independent of their characteristics. Another important benefit of Randomisation is that statistical methods of analysis are based on what we expect to happen in random samples from populations with specified characteristics. The Protocol must state the method used for Randomisation.

 

The Study should use the maximum degree of blindness that is possible. Study subjects, investigator or any other party concerned with the study may observe and respond by knowledge of which treatment was given.  To avoid such bias it is often desired that the patient or any other person involved with the study does not know which treatment was given. Where a sealed code for each individual treatment has been assigned in a blinded randomized study it should be kept both at the site of the investigation and with the sponsor. 

 

The Protocol must state the conditions under which the code is allowed to be broken and by whom.  The system of breaking the code should be such that it allows access to only one Subject’s treatment at a time.  The coding system for the Investigational Product(s) should include a mechanism that permits rapid identification of the products in case of a medical emergency, but does not permit undetectable breaks of the blinding.

 

6.3.            Statistical Analysis

The type(s) of Statistical Analyses to be used must be clearly identified and should form basis of the statistical model for the Study. Any subsequent deviation(s) should be described and justified in the Final Report.  The need and extent of an interim analysis must be specified in the Protocol.  The results of the statistical analyses should be presented in a manner that is likely to facilitate the interpretation of their clinical importance, e.g. by estimates of the magnitude of the treatment effect / difference and confidence intervals rather than sole reliance on significance testing.

 

Missing, unused and spurious data should be accounted for during the statistical analyses.  All such omissions must be documented to enable review.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

SPECIAL CONCERNS

 

7.1             Clinical Trials of Vaccines

 

           7.1.1            Phases of Vaccine Trials

The guidelines to conduct the clinical trial on investigational vaccines are similar to those governing a clinical trial. The phase of these trials differ from drug trials as given below:

 

Phase I: This refers to the first introduction of a vaccine into a human population for determination of its safety and biological effects including immunogenicity. This phase includes study of dose and route of administration and should involve low risk subjects. For example, immunogenicity to hepatitis vaccine should not be determined in high-risk subjects.

 

Phase II: This refers to the initial trials examining effectiveness (immunogenicity) in a limited number of volunteers. Vaccines can be prophylactic and therapeutic in nature. While prophylactic vaccines are given to normal subjects, therapeutic or curative vaccines may be given to patients suffering from particular disease.

 

Phase III: This focuses on assessments of safety and effectiveness in the prevention of disease, involving controlled study on a larger number of volunteers (in thousands) in multi-centres.

 

           7.1.2.            Guidelines

·        The sponsor and investigator should be aware of the approval process(es) involved in conducting clinical trials of vaccines. They should familiarize themselves with the guidelines provided by Drug Controller General (India), Department of Biotechnology (DBT) and Ministry of Environment and Genetic Engineering Approval Committee (GEAC) in the case of vaccines produced by recombinant DNA technology.  See Appendix III.

·        Some vaccines that contain active or live-attenuated microorganisms can possibly possess a small risk of producing that particular infection. The subjects to be vaccinated should be informed of the same. 

·        The subjects in control groups or when subjected to ineffective vaccines run a risk of contracting the disease.

·        The risks associated with vaccines produced by recombinant DNA techniques are not completely known. However, for all the recombinant vaccines/products the guidelines issued by the Department of Biotechnology should be strictly followed.

·        Trials should be conducted by investigator with the requisite experience and having necessary infrastructure for the laboratory evaluation of seroconversion.

·        Protocols for such trials should include appropriate criteria for selection of subjects, plan of frequency of administration of the test vaccine in comparison with the reference vaccine. It should accompany detailed validation of testing method to detect the antibody titter levels.

·        It should specify methodology to be adopted for prevention of centrifuged serum for the purpose of testing.

·        The investigator should be provided with Quality Control data of the experimental batch of the vaccine made for the purpose of clinical trials.

·        The sponsor should provide the Independent Ethics Committee approval of the nodal body (ies) to carry out clinical trials with the vaccine.

·        The generic version of new vaccines already introduced in the other markets after step up clinical trials including extensive Phase III trials should be compared with the reference vaccine with regard to seroconversion in a comparative manner in a significant sample size.

·        Post Marketing Surveillance (PMS) should be required following seroconversion studies. PMS data should be generated in a significant sample size sensitive to detect side effects and address other safety issues.

·        Protocols for test of new vaccine should contain a section giving details of steps of manufacture, in-process quality control measures, storage conditions, stability data and a flow chart of various steps taken into consideration for manufacture of vaccine. It should also contain detailed method of quality control procedure with the relevant references.                                                                                                                                                                                                                                                              

 

7.2.            Clinical Trials of Contraceptives

 

·                    All procedures for clinical trials are applicable. Subjects should be clearly informed about the alternative available.

·                    In women where implant has been used as a contraceptive for trial, a proper follow up for removal of the implant should be done, whether the trial is over or the subject has withdrawn from the trial.

·                    Children borne due to failure of contraceptives under study should be followed up for any abnormalities if the woman does not opt for medical termination of pregnancy.

 

 

 

 

7.3             Clinical trials with surgical procedures/ medical devices

 

            Of late, biomedical technology has made considerable progress in the conceptualisation and designing of bio-equipments. Several medical devices and critical care equipments have been developed and many more are in various stages of development. However, only through good manufacturing practices (GMP) can the end products reach the stage of utilization by society. Most of these products are only evaluated by Central Excise testing for taxation purposes, which discourages entrepreneurs to venture in this area with quality products especially when they do not come under the strict purview of the existing regulatory bodies like ISI, BSI and Drug Controller General. This is evidenced by the very low number of patents or propriety medical equipments manufactured and produced in the country. As the capacity of the country in this area is improving day by day the need for a regulatory mechanism/ authority is increasingly obvious. The concept of regulations governing investigations involving biomedical devices is therefore relatively new in India. At present, except for needles and syringes these are not covered by the Drugs and Cosmetics Act, 1940. The Chief Executive of the Society of Biomedical Technology (SBMT) set up under the Defence Research Development Organisation (DRDO) has drafted a proposal for the setting up of a regulatory, tentatively named as the Indian Medical Devices Regulatory Authority (IMDRA). Until the guidelines are formulated and implemented by this regulatory Authority clinical trials with biomedical devices should be approved on case to case basis by committees constituted for the specific purpose.

 

 

            7.3.1.            Definitions:

 

Medical devices: A medical device is defined as an inert diagnostic of therapeutic article that does not achieve any of its principal intended purposes through chemical action, within or on the body unlike the medicated devices which contain pharmacologically active substances which are treated as drugs. Such devices include diagnostic test kits, crutches, electrodes, pacemakers, arterial grafts, intra-ocular lenses, orthopaedic pins and other orthopaedic accessories.

 

Depending upon risks involved the devices could be classified as follows:

 

a.      Non critical devices: An investigational device that does not present significant risk to the patients e.g. Thermometer, B.P. apparatus.

b.      Critical devices: An investigational device that presents a potential risk to the health, safety, welfare of the subject- for example, pacemakers, implants, internal catheters.

All the general principles of clinical trials described for clinical trials should also be considered for trials of medical devices. As for the drugs, safety evaluation and pre-market efficacy of devices for 1-3 years with data on adverse reactions should be obtained before pre-market certification. The duration of the trial and extent of use may be decided in case to case basis by the appropriate authorities. However, the following important factors that are unique to medical devices should be taken into consideration while evaluating the related research projects.

 

 

7.3.2.            Guidelines

o       Safety data of the medical device in animals should be obtained and likely risks posed by the device should be considered.

o       A clinical trial of medical devices is different from drug trials, as former can not be done in healthy volunteers. Hence phase I of drug trial is not necessary for trial on devices.

o       Medical devices used within the body may have greater risk potential than those used on or outside the body, for example, orthopaedic pins Vs crutches.

o       Medical device not used regularly have less risk potential than those used regularly, for example, contact lens Vs intraocular lenses.

o       Safety procedures to introduce a medical device in the patient should also be followed as the procedure itself may cause harm to the patient.

o       Informed consent procedures should be followed as in drug trials. The patient information sheet should contain information on following procedures to be adopted if the patient decides to withdraw from the trial.

 

7.4.      Clinical trials for Diagnostic Agents - Use of Radio-active Materials and X- Rays

 

In human beings, for investigation and treatment, different radiations- X-rays, gamma rays and beta rays, radio opaque contrast agents and radioactive materials are used. The relative risks and benefits of research proposal utilizing radioactive materials or X-rays should be evaluated. Radiation limits for the use of such materials and X-Rays should be in accordance with the limits set forth by the regulatory authority (BARC) for such materials. (BARC-Bhabha Atomic Research Centre, Mumbai).

 

            7.4.1.  Guidelines

§               Informed consent should be obtained before any diagnostic procedures.

§               Information to be gained should be gathered using methods that do not expose subjects to more radiation than exposed normally.

§               Research should be performed on patients undergoing the procedures for diagnostic or therapeutic purposes.

§               Safety measures should be taken to protect research subjects and others who may be exposed to radiation.

§               The protocol should make adequate provisions for detecting pregnancies to avoid risks of exposure to the embryo.

§               Information to subject about possible genetic damage to offspring should be given.

§               Non-radioactive diagnostic agents are considered as drugs and the same guidelines should be followed when using them.

§               Ultrasound to be submitted wherever possible.

 

7.5             Clinical trials of Herbal Remedies and Medicinal Plants

For the herbal remedies and medicinal plants that are to be clinically evaluated for use in the Allopathic System and which may later be used in allopathic hospitals, the procedures laid down by the office of the DCG (I) for allopathic drugs should be followed. This does not pertain to guidelines issued for clinical evaluation of Ayurveda, Siddha or Unani drugs by experts in those systems of medicine which may be used later in their own hospitals and clinics. All the general principles of clinical trials described earlier pertain also to herbal remedies. However, when clinical trials of herbal drugs used in recognized Indian systems of Medicine and Homoeopathy are to be undertaken in Allopathic Hospitals, associations of physicians from the concerned system as co-investigators/ collaborators/ members of the expert group is desirable for designing and evaluating the Study.

 

7.5.1.  Categories of Herbal Products

            The herbal products can belong to any of the three categories given below:

a.            A lot is known about the use of a plant or its extract in the ancient Ayurveda, Siddha or Unani literature or the plant may actually be regularly used by physicians of the traditional systems of medicine for a number of years. The substance is being clinically evaluated for same indication for which it is being used or as has been described in the texts.

b.            When an extract of a plant or a compound isolated from the plant has to be clinically evaluated for a therapeutic effect not originally described in the texts of traditional systems or, the method of preparation is different, it has to be treated as a new substance or new chemical entity (NCE) and the same type of acute, subacute and chronic toxicity data will have to be generated as required by the regulatory authority before it is cleared for clinical evaluation.

c.            An extract or a compound isolated from a plant which has never been in use before and has not ever been mentioned in ancient literature, should be treated as a new drug, and therefore, should undergo all regulatory requirements before being evaluated clinically.

 

7.5.2.            Guidelines

·        It is important that plants and herbal remedies currently in use or mentioned in literature of recognized Traditional System of Medicine is prepared strictly in the same way as described in the literature while incorporating GMP norms for standardization. It may not be necessary to undertake phase I studies. However, it needs to be emphasized that since the substance to be tested is already in used in Indian Systems of Medicine or has been described in their texts, the need for testing its toxicity in animals has been considerably reduced. Neither would any toxicity study be needed for phase II trial unless there are reports suggesting toxicity or when the herbal preparation is to be used for more than 3 months. It should be necessary to undertake 4-6 weeks toxicity study in 2 species of animals in the circumstances pointed out in the preceding sentence or when a larger multicentric phase III trial is subsequently planned based on results of phase II study.

 

·        Clinical trials with herbal preparations should be carried out only after these have been standardized and markers identified to ensure that the substances being evaluated are always the same. The recommendations made earlier regarding informed consent, subject, inducements for participation, information to be provided to the subject, withdrawal from study and research involving children or persons with diminished autonomy, all apply to trials on plant drugs also. These trials have also got to be approved by the appropriate scientific and ethical committees of the concerned Institutes. However, it is essential that such clinical trials be carried out only when a competent Ayurvedic, Siddha or Unani physician is a co-investigator in such a clinical trial. It would neither ethically acceptable nor morally justifiable, if an allopathic physician, based on references in ancient literature of above-mentioned traditional systems of Medicine, carries out clinical evaluation of the plant without any concept or training in these systems of medicine. Hence, it is necessary to associate a specialist from these systems and the clinical evaluation should be carried out jointly.

 

·        When a Folklore medicine / Ethno-medicine is ready for commercialisation after it has been scientifically found to be effective, then the legitimate rights/ share of the Tribe or Community from whom the knowledge was gathered should be taken care of appropriately while applying for the Intellectual Property Rights and / Patents for the product.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

APPENDICES

 

Appendix I:

WORLD MEDICAL ASSOCIATION DECLARATION OF HELSINKI

Ethical Principles for Medical Research Involving Human Subjects


Adopted by the 18th WMA General Assembly
Helsinki, Finland, June 1964
and amended by the
29th WMA General Assembly, Tokyo, Japan, October 1975
35th WMA General Assembly, Venice, Italy, October 1983
41st WMA General Assembly, Hong Kong, September 1989
48th WMA General Assembly, Somerset West, Republic of South Africa, October 1996
and the
52nd WMA General Assembly, Edinburgh, Scotland, October 2000

                

A.            INTRODUCTION

1.         The World Medical Association has developed the Declaration of Helsinki as a statement of ethical principles to provide guidance to physicians and other participants in medical research involving human subjects. Medical research involving human subjects includes research on identifiable human material or identifiable data.

2.         It is the duty of the physician to promote and safeguard the health of the people. The physician's knowledge and conscience are dedicated to the fulfilment of this duty.

3.         The Declaration of Geneva of the World Medical Association binds the physician with the words, "The health of my patient will be my first consideration," and the International Code of Medical Ethics declares that, "A physician shall act only in the patient's interest when providing medical care which might have the effect of weakening the physical and mental condition of the patient."

4.     Medical progress is based on research, which ultimately must rest in part on experimentation involving human subjects.

5.         In medical research on human subjects, considerations related to the well-being of the human subject should take precedence over the interests of science and society.

6.         The primary purpose of medical research involving human subjects is to improve prophylactic, diagnostic and therapeutic procedures and the understanding of the aetiology and pathogenesis of disease. Even the best proven prophylactic, diagnostic, and therapeutic methods must continuously be challenged through research for their effectiveness, efficiency, accessibility and quality.

7.         In current medical practice and in medical research, most prophylactic, diagnostic and therapeutic procedures involve risks and burdens.

8.     Medical research is subject to ethical standards that promote respect for all human beings and protect their health and rights. Some research populations are vulnerable and need special protection. The particular needs of the economically and medically disadvantaged must be recognised. Special attention is also required for those who cannot give or refuse consent for themselves, for those who may be subject to giving consent under duress, for those who will not benefit personally from the research and for those for whom the research is combined with care.

9.     Research Investigators should be aware of the ethical, legal and regulatory requirements for research on human subjects in their own countries as well as applicable international requirements. No national ethical, legal or regulatory requirement should be allowed to reduce or eliminate any of the protections for human subjects set forth in this Declaration.

 

B.            BASIC PRINCIPLES FOR ALL MEDICAL RESEARCH

10.       It is the duty of the physician in medical research to protect the life, health, privacy, and dignity of the human subject.

11.            Medical research involving human subjects must conform to generally accepted scientific principles, be based on a thorough knowledge of the scientific literature, other relevant sources of information, and on adequate laboratory and, where appropriate, animal experimentation.

12.     Appropriate caution must be exercised in the conduct of research which may affect the environment, and the welfare of animals used for research must be respected.

13.       The design and performance of each experimental procedure involving human subjects should be clearly formulated in an experimental protocol. This protocol should be submitted for consideration, comment, guidance, and where appropriate, approval to a specially appointed ethical review committee, which must be independent of the investigator, the sponsor or any other kind of undue influence. This independent committee should be in conformity with the laws and regulations of the country in which the research experiment is performed. The committee has the right to monitor ongoing trials. The researcher has the obligation to provide monitoring information to the committee, especially any serious adverse events. The researcher should also submit to the committee, for review, information regarding funding, sponsors, institutional affiliations, other potential conflicts of interest and incentives for subjects.

14.       The research protocol should always contain a statement of the ethical considerations involved and should indicate that there is compliance with the principles enunciated in this Declaration.

15.     Medical research involving human subjects should be conducted only by scientifically qualified persons and under the supervision of a clinically competent medical person. The responsibility for the human subject must always rest with a medically qualified person and never rest on the subject of the research, even though the subject has given consent.

16.       Every medical research project involving human subjects should be preceded by careful assessment of predictable risks and burdens in comparison with foreseeable benefits to the subject or to others. This does not preclude the participation of healthy volunteers in medical research. The design of all studies should be publicly available.

17.     Physicians should abstain from engaging in research projects involving human subjects unless they are confident that the risks involved have been adequately assessed and can be satisfactorily managed. Physicians should cease any investigation if the risks are found to outweigh the potential benefits or if there is conclusive proof of positive and beneficial results.

18.     Medical research involving human subjects should only be conducted if the importance of the objective outweighs the inherent risks and burdens to the subject. This is especially important when the human subjects are healthy volunteers.

19.     Medical research is only justified if there is a reasonable likelihood that the populations in which the research is carried out stand to benefit from the results of the research.

20.       The subjects must be volunteers and informed participants in the research project.

21.       The right of research subjects to safeguard their integrity must always be respected. Every precaution should be taken to respect the privacy of the subject, the confidentiality of the patient's information and to minimize the impact of the study on the subject's physical and mental integrity and on the personality of the subject.

22.       In any research on human beings, each potential subject must be adequately informed of the aims, methods, sources of funding, any possible conflicts of interest, institutional affiliations of the researcher, the anticipated benefits and potential risks of the study and the discomfort it may entail. The subject should be informed of the right to abstain from participation in the study or to withdraw consent to participate at any time without reprisal. After ensuring that the subject has understood the information, the physician should then obtain the subject's freely given informed consent, preferably in writing. If the consent cannot be obtained in writing, the non-written consent must be formally documented and witnessed.

23.       When obtaining informed consent for the research project the physician should be particularly cautious if the subject is in a dependent relationship with the physician or may consent under duress. In that case the informed consent should be obtained by a well-informed physician who is not engaged in the investigation and who is completely independent of this relationship.

24.       For a research subject who is legally incompetent, physically or mentally incapable of giving consent or is a legally incompetent minor, the investigator must obtain informed consent from the legally authorised representative in accordance with applicable law. These groups should not be included in research unless the research is necessary to promote the health of the population represented and this research cannot instead be performed on legally competent persons.

25.       When a subject deemed legally incompetent, such as a minor child, is able to give assent to decisions about participation in research, the investigator must obtain that assent in addition to the consent of the legally authorised representative.

26.     Research on individuals from whom it is not possible to obtain consent, including proxy or advance consent, should be done only if the physical/mental condition that prevents obtaining informed consent is a necessary characteristic of the research population. The specific reasons for involving research subjects with a condition that renders them unable to give informed consent should be stated in the experimental protocol for consideration and approval of the review committee. The protocol should state that consent to remain in the research should be obtained as soon as possible from the individual or a legally authorised surrogate.

27.       Both authors and publishers have ethical obligations. In publication of the results of research, the investigators are obliged to preserve the accuracy of the results. Negative as well as positive results should be published or otherwise publicly available. Sources of funding, institutional affiliations and any possible conflicts of interest should be declared in the publication. Reports of experimentation not in accordance with the principles laid down in this Declaration should not be accepted for publication.

 

C.            ADDITIONAL PRINCIPLES FOR MEDICAL RESEARCH COMBINED WITH MEDICAL CARE

28.       The physician may combine medical research with medical care, only to the extent that the research is justified by its potential prophylactic, diagnostic or therapeutic value. When medical research is combined with medical care, additional standards apply to protect the patients who are research subjects.

29.       The benefits, risks, burdens and effectiveness of a new method should be tested against those of the best current prophylactic, diagnostic, and therapeutic methods. This does not exclude the use of placebo, or no treatment, in studies where no proven prophylactic, diagnostic or therapeutic method exists.

30.       At the conclusion of the study, every patient entered into the study should be assured of access to the best proven prophylactic, diagnostic and therapeutic methods identified by the study.

31.       The physician should fully inform the patient which aspects of the care are related to the research. The refusal of a patient to participate in a study must never interfere with the patient-physician relationship.

32.       In the treatment of a patient, where proven prophylactic, diagnostic and therapeutic methods do not exist or have been ineffective, the physician, with informed consent from the patient, must be free to use unproven or new prophylactic, diagnostic and therapeutic measures, if in the physician's judgement it offers hope of saving life, re-establishing health or alleviating suffering. Where possible, these measures should be made the object of research, designed to evaluate their safety and efficacy. In all cases, new information should be recorded and, where appropriate, published. The other relevant guidelines of this Declaration should be followed.


Appendix II:

Schedule y

Requirements and guidelines on clinical trials for import and manufacture of new drug

 

  1. Clinical Trials

 

    1. Nature of trials: The clinical trials required to be carried out in the country before a new drug is approved for marketing depend on the status of the drug in other countries. If the drug is already approved/marketed, phase III trials as required under item 7 of Appendix I (to Sch. Y) usually are required. If the drug is not approved/ marketed, trials are generally allowed to be initiated at one phase earlier to the phase of trials in other countries.

 

For new drug substances discovered in other countries phase I trials are not usually allowed to be initiated in India unless phase I data as required under Item 5 of the said Appendix from other countries are available. However, such trials may be permitted even in the absence of phase I data from other countries if the drug is of special relevance to the health problem of India.

 

For new drug substances discovered in India, clinical trials are required to be carried out in India right from phase I as required from Item 5 of the said Appendix, through phase III as required under Item 7 of the said Appendix, permission to carry out these trials is generally given in stages, considering the data emerging from earlier phase.

 

    1. Permission for trials: Permission to initiate clinical trials with a new drug may be obtained by applying in Form 12 for a test license (TL) to import or manufacture the drug under the Rules. Data appropriate for the various phases of clinical trials to be carried out should accompany the application as per format given in Appendix I (Items I-4). In addition, the protocol for proposed trials, case report forms to be used, and the names of investigators and institutions should also be submitted for approval. The investigators selected should possess appropriate qualifications and experience and should have such investigational facilities as are germane to the proposed trials protocol.

 

Permission to carry out clinical trials with a new drug is issued along with a test license in Form 11.

 

It is desirable that protocols for clinical trials be reviewed and approved by the institution’s ethical committee. Since such committees at present do not exist in all institutions, the approval granted to a protocol by the ethical committee of one institution will be applicable to the use of that protocol in other institutions, which do not have an ethical committee. In case none of the trial centres/institutions has an ethical committee the acceptance of the protocol by the investigator and its approval by the Drugs Controller (India) or any officer as authorized by him to do so will be adequate to initiate the trials.

 

For new drugs having potential for use in children, permission for clinical trials in the paediatric age group is normally given after phase III trials as required under item 7 of the said Appendix, in adults are completed. However, if the drug is of value primarily in a disease of children, early trials in the paediatric age group may be allowed.

 

 

    1. Responsibilities of Sponsor/Investigator: Sponsors are required to submit to the Licensing Authority as given under Rule 21 an annual status report on each clinical trial, namely, ongoing, completed, or terminated. In case a trial is terminated, reason for this should be stated. Any unusual, unexpected, or serious adverse drug reaction (ADR) detected during a trial should be promptly communicated by the sponsor to the Licensing Authority under Rule 21 and the other investigators.

In all trials an informed, written consent is required to be obtained from each volunteer/patient in the prescribed form (See Appendix V), which must be signed, by the patient/volunteer and the chief investigator.

 

  1. Chemical and Pharmaceutical Information

 

Most of the data under this heading (See Appendix I to Sch. Y, Item 2) are required with the application for marketing permission. When the application is for clinical trials only, information covered in item 2.1 to 2.3 of Appendix I will usually suffice.

 

  1. Animal Toxicology

 

    1. Acute toxicity: Acute toxicity studies (See Appendix I – Sch. Y - Item 4.2) should be carried out in at least two species, usually mice and rats using the same route as intended for humans. In addition, at least two more route should be used to ensure systemic absorption of the drug, this route may depend on the nature of the drug. Mortality should be looked for up to 72 hours after parenteral administration and up to 7 days after oral administration. Symptoms, signs and mode of death should be reported, with appropriate macroscopic and microscopic findings where necessary. LD 50s should be reported preferably with 95 percent confidence limits, if LD 50s cannot be determined, reasons for this should be stated.

 

    1.  Long-term toxicity: Long-term toxicity studies (see Appendix I – Sch. Y, Item 1.3) should be carried out in at least two mammalian species, of which one should be a non-rodent. The duration of study will depend on whether the application is for marketing permission or for clinical trial, and in the later case, on the phases of trials (see Appendix III). If a species is known to metabolize the drug in the same way as humans, it should be preferred.

In long-term toxicity studies the drug should be administered 7 days a week by the route intended for clinical use in humans. The number of animals required for these studies, i.e. the minimum number on which data should be available, is shown in Appendix IV to Sch. Y.

 

A control group of animals, given the vehicle alone, should always be included, and three other groups should be given graded doses of the drug; the highest dose should produce observable toxicity, the lowest dose should not cause observable toxicity, but should be comparable to the intended therapeutic dose in humans or a multiple of it, eg: 2.5x to make allowance for the sensitivity of the species; the intermediate dose should cause some symptoms, but not gross toxicity or death, and may be placed logarithmically between the other two doses.

 

The variables to be monitored and recorded in long-term toxicity studies include behavioral, physiological, biochemical and microscopic observations.

 

    1. Reproduction studies: Reproduction studies (see Appendix I – Sch. Y, item 4.4) need to be carried out only if the new drug is proposed to be studied or used in women of childbearing age. Two species should generally be used, one of them being non-rodent if possible.

 

(a)Fertility studies: The drug should be administered to both males and females, beginning a sufficient number of days before mating. In females the medication should be continued after mating and the pregnant one should be treated throughout pregnancy. The highest dose used should not affect general health or growth of the animals. The route of administration should be the same as for therapeutic use in humans. The control and the treated group should be of similar size and large enough to give at least 20 pregnant animals in the control group of rodents and at least 8 pregnant animals in the control group of non-rodents. Observations should include total examination of the litters from both the groups, including spontaneous abortions, if any.

 

(b)Teratogenicity studies: The drugs should be administered throughout the period of organogenesis, using three dose levels. One of the doses should cause minimum maternal toxicity and one should be the proposed dose for clinical use in humans or multiple of it. The route of administration should be the same as for human therapeutic use. The control and the treated groups should consist of at least 20 pregnant females in case of non-rodents, on each dose used. Observations should include the number of implantation sites, resorptions if any; and the number of fetuses with their sexes, weights and malformations if any.

 

(c) Perinatal studies: The drug should be administered throughout the last third of pregnancy and then through lactation and weaning. The control of each treated group should have at least 12 pregnant females and the dose which causes low foetal loss should be continued throughout lactation weaning. Animals should be sacrificed and observations should include macroscopic autopsy and where necessary, histopathology.

 

4.Local toxicity: These studies (see Appendix I, Sch. Y, Item 4.5) are required when the new drug Is proposed to be used typically in humans. The drug should be applied to an appropriate site to determine local effects in a suitable species such as guinea pigs or rabbits, if the drug is absorbed from the site of applications, appropriate systemic toxicity studies will be required.

 

      5.Mutagenicity and Carcinogenicity :  These studies (see Appendix I, Sch. Y Item 4,6) are required to be carried out if the drug or its metabolite is related to a known carcinogen or when the nature and action of the drug is such as to suggest a carcinogenic/mutagenic potential.  For carcinogenicity studies, at least two species should be used. These species should not have high incidence of spontaneous tumors and should preferably be known to metabolize the drug in the same manner as humans.  At least three does levels should be used; the highest does should be sub-lethal but cause observable toxicity; the lowest does should be comparable to the intended human therapeutic does or a multiple of it, eg: 2.5x; to make allowance for the sensitivity of the species; the intermediate does to be placed logarithmically between the other two doses.  A control group should always be included.  The drug should be administered 7 days a week or a fraction of the life span comparable to the fraction of human life span over which the drug is likely to be used therapeutically.  Observations should include macroscopic changes observed at autopsy and detailed histopathology.

 

4.  Animal Pharmacology

            Specific pharmacological actions (see Appendix I to Sch. Y, Item 3.2) are those with therapeutic-potential for humans.  These should be described according to the animal models and species used.  Wherever possible, dose-response relationships and ED 50s should be given.  Special studies to elucidate mode of action may also be described.

            General pharmacological action (see Appendix I to Sch. Y, Item 3.3) are effects on other organs and systems, especially cardiovascular, respiratory and central nervous systems.

 

            Pharmacokinetic data help relate drug effect to plasma concentration and should be given to the extent available.

 

5.  Human/Clinical Pharmacology trials (Phase I)

            The objective of phase I of trials (see Appendix I, Sch. Y, Item 5) is to determine the maximum tolerated dose in humans; pharmacodynamic effects, adverse reactions, if any, with their nature and intensity; and pharmacokinetic behaviors or the drug as far as possible.  These studies are carried out in healthy adult males, using clinical, physiological and biochemical observations.  At least 2 subjects should be used on each dose.

 

            Phase I trials are usually carried out by investigators trained in clinical pharmacology and having the necessary facilities to closely observe and monitor the subjects.  These may be carried out at one or two centers.

 

6.  Exploratory trials (Phase II)

            In phase II trial (see Appendix I to Sch. Y, Item 6) a limited number of patients are studied carefully to determine possible therapeutic uses, effective dose range and further evaluation of safety and pharmacokinetics.  Normally 10-12 patients should be studied at each dose level.  These studies are usually limited to 3-4 centers and carried out by clinicians specialized on the concerned therapeutic areas and having adequate facilities to perform the necessary investigations for efficacy and safety.

 

7.  Confirmatory trials (Phase III)

 

            The purpose of these trials (see Appendix I to Sch. Y, Item 7) is to obtain sufficient evidence about the efficacy and safety of the drug in a larger number of patients, generally in comparison with a standard drug and/or a placebo as appropriate.  These trials may be carried out by clinicians in the concerned therapeutic areas, having facilities appropriate to the protocol.  If  the drug is already approved/marketed in other countries, phase III data should generally be obtained on at least 100 patients distributed over 3-4 centres primarily to confirm the efficacy and safety of the drug, in Indian patients when used as recommended in the product monograph for the claims made.

 

                        If the drug is a new drug substance discovered in India and not marketed in any other country, phase III data should be obtained on at least 500 patients distributed over 10-15 centers.  In addition, data on adverse drug reactions observed during clinical use of the drug as recommended and to provide a report on its efficacy and adverse drug reactions in the treated patients.  The selection of clinicians for such monitoring and supply of drug to them will need approval of the licensing authority under Rule-21 of Drugs & Cosmetics Rules.

 

8.  Special Studies

 

          (A)   These include studies on solid oral dosage forms, such as, bioavailability and dissolution studies.  These are required to be submitted on the formulations manufactured in the country.  (See Appendix I, Items 8.1 and 8.2)

            (B)   These include studies to explore additional aspects of the drug, eg: use in elderly patients or patients with renal failure, secondary or ancillary effects, interactions, etc. (See Appendix I to Sch. Y, Item 8.1 and 8.2).

 

9.  Submission of Reports (Appendix II to Schedule Y)

 

The reports of completed clinical trials shall be submitted by the applicant duly signed by the investigator within a stipulated period of time.  The applicant should do so even if he is no longer interested to market the drug in the country unless there are sufficient reasons for not doing so.

 

10.  Regulatory status in other counties

 

It is important to state if any restrictions have been placed on the use of the drug in any other country, eg: dosage limits, exclusion of certain age groups, warnings about adverse drug reaction, etc. (See Appendix I, Sch. Y, Item 9.2)

Likewise, if the drug has been withdrawn from any country especially by a regulatory directive such information should e furnished along with reasons and their relevance, if any, to India (See Appendix I, Item 9.1(d)).

 

11.  Marketing Information

 

The product monograph should comprise the full prescribing information necessary to enable a physician to use the drug properly.  It should include description, actions, indications, dosage precaution, drug interactions, warnings and adverse reactions.

The drafts of label and carton texts should comply with provisions of Rules 96 and 97 of the said rules.

APPENDIX VI to Schedule Y

Data requirements of Fixed Dose Combinations

 

Fixed Dose combinations (FDC) fall into four groups and their data requirements accordingly

 

(a)   The first group of FDC includes those in which one or more of the active ingredients is a new drug. Such FDC are treated in the same way as any other new drug , both the clinical trials and for marketing permission (see Rule 122-E, Item (a)).

 

(b)   The second group of FDC includes those in which active ingredients already approved/marketed individually are combined for the first time, for a particular claim and where the ingredients are likely to have significant interaction of a pharmacodynamic or pharmacokinetic nature (see Rule 122-E, item (c)). For permission to carry out clinical trials with such FDC, a summary of available pharmacological, toxicological and clinical data on the individual ingredients should be submitted, along with the rationale for combining them in the proposed ratio. In addition, acute toxicity data (LD 50) and pharmacological data should be submitted on the individual ingredient as well as their combinations in the proposed ratio. If clinical trials have been carried out with the FDC in other countries, reports of such trials should be submitted. If the FDC is marketed abroad, the regulatory status in other countries should be stated. (See Appendix I, Item 9).

For marketing permission, the reports of clinical trials carried out with the FDC in India should be submitted. The nature of trials depending on the claims to be made and the data already available.

 

(c)   The third group of FDC includes those which are already marketed, but in which it is proposed either to change the ratio of active ingredients or to make a new therapeutic claim.

 

(d)   The fourth group of FDC includes those whose individual active ingredients have been widely used in particular indication for years, there concomitant use is often necessary and no claim is proposed to be made other than convenience, and a stable acceptable dosage form and the ingredients are unlikely to have significant interaction of a pharmacodynamic or pharmacokinetic nature.

 

No additional animals or human data are generally required for these FDC, and marketing permission may be granted if the FDC has an acceptable rationale.

APPENDIX IV

INVESTIGATOR’S BROCHURE (IB)

 

Introduction

The Investigator’s Brochure is a compilation of the clinical and non-clinical data on the Investigational Product(s) that are relevant to a study of the product(s). It provides the investigator(s) and others involved in the study with the information on the rationale to facilitate compliance with the key features of the protocol, such as the dose, dose frequency/interval, methods of administration and safety monitoring procedures. The IB also provides background material to support the clinical management of the study subjects. The information contained in the IB should be in a concise, simple, objective, balanced, and non-promotional form to enable an understanding unbiased risk-benefit assessment of the appropriateness of the proposed trial. For this reason, a medically qualified person should generally participate in the editing of an IB, but the contents of the IB should be approved by the disciplines that generated the described data. The IB should be revised whenever necessary in compliance with the sponsor’s written procedures, the stage of development and the generation of relevant new information. However, any relevant new information that is considered important should be communicated to the Investigator(s), Ethics Committee and the Regulatory Authorities immediately, even before it can be methodically included in the IB.

 

Contents of the Investigator’s Brochure

The IB should include Sponsor’s name, the reference number allocated to the study, the identity of each investigational product (ie. research number, chemical or approved generic name, and trade name(s) where legally permissible and desired by the sponsor).  The IB should bear an edition number and date.  Besides, wherever applicable it also bears a reference to the number and date of the edition it supersedes.

 

The Sponsor may wish to include a statement instructing the readers to treat the IB as a confidential document for the sole purpose of the Study for which it has been prepared.

 

 

The IB should contain the following sections, each with literature references where appropriate:

1  Table of Contents

 

2  Introduction: This section includes information relevant to the stage of clinical development including the significant physical properties , chemical properties, pharmaceutical, pharmacological (pharmacological class, advantages over other substances in that class and rationale for performing the proposed study), toxicological, pharmacokinetic, metabolic, and clinical information (anticipated prophylactic/ therapeutic or diagnostic indication(s)) of all active ingredients.  The introductory statement should necessarily provide the general approach to be followed in evaluating the Investigational Product.

- Time to onset of effects

- Reversibility of effects

- Duration of effects

- Dose response

 

The following sections should discuss the most important findings from the studies, including the dose response of observed effects, the relevance to humans, and any aspects to be studied in humans. If applicable, the effective and non-toxic dose findings in the same animal species should be compared (i.e. The therapeutic index should be discussed). The relevance of this information to the proposed human dosing should be addressed. Whenever possible, comparisons should be made in terms of blood/tissue levels rather than on a mg/kg basis.

(a) Non-clinical Pharmacological (Pharmacodymanics)

A summary of the pharmacological aspects of the investigational product and, where appropriate, its significant metabolites studied in animals, should be included. Such a summary should incorporate studies that assess potential therapeutic activity (e.g. efficacy models, receptor binding, and specificity) as well as those that assess safety (eg. special studies to assess pharmacological actions other than the intended therapeutic effect(s)).

 

 

(b) Pharmacokinetics and Product Metabolism in Animals

A summary of the pharmacokinetics and biological transformation and disposition of the investigational product in all species studied should be given. The discussion of the findings should address the absorption and the local and systemic bioavailability of the investigational product and its metabolites, and their relationship to the pharmacological and toxicological findings in animal species.

 

(c) Toxicology

A summary of the toxicological effects found in relevant studies conducted in different animal species should be described under the following headings where appropriate:

            - Single dose

            - Repeated dose

            - Carcinogenicity

            - Special studies (eg. irritancy and sensitisation)

-Reproductive toxicity

- Genotoxicity (mutagenicity)

 

5  Effects in Humans:

A thorough discussion of the known effects of the investigational product(s) in humans should be provided, including information on pharmacokinetics, metabolism, pharmacodynamics, dose response, safety, efficacy, and other pharmacological activities. Brief summaries of other clinical studies conducted on the same product should be provided if available. 

 

(a) Pharmacokinetics and Product Metabolism in Humans

            A summary of information on the pharmacokinetics of the investigational

product(s) should be presented, including the following, if available:

Bioavailability of the investigational product (absolute, where possible, and/or relative) using a reference dosage form.

Population subgroups (eg. gender, age, and impaired organ function).

Interactions (eg. Product-product interactions and effects of food).

Other pharmacokinetic data (eg. results of population studies performed within clinical trial(s).

 

(b) Safety and Efficacy

Information should be provided about the Investigational Product(s)’ (including their metabolites, where appropriate) safety pharmacodynamics, efficacy and dose response(s) that were obtained from preceding trials in humans (healthy volunteers and/or patients). The implications of the information should be discussed. In cases where a number of clinical studies have been completed, the use of summaries of safety and efficacy across multiple trials by indications in subgroups may provide a clear presentation of the data. Tabular summaries of adverse drug reactions for all the clinical trials (including those for all the studied indications) would be useful. Important differences in adverse drug reaction patterns/incidences across indications or subgroups should be discussed.

 

The IB should provide a description of the possible risks and adverse drug reactions to be anticipated on the basis of prior experiences with the product under investigation and with related products. A description should also be provided of the precautions or special monitoring to be done as part of the investigational use of the product(s).

 

(c) Regulatory & Post-marketing Experiences

The IB should identify countries where the investigational product has been marketed or approved. Any significant information arising from the marketed use should be summarised (eg. formulations, dosages, routes of administration, and adverse product reactions). The IB should also identify all the countries where the investigational product did not receive approval/registration for marketing or was withdrawn from marketing/registration.

 

6  Summary of Data and Guidance for the Investigator
