Assignment on Regulatory Prespectives of Clinical Trials
1. ICH-GCP GUIDELINES
INTRODUCTION:
Good Clinical Practice (GCP) is an international ethical
and scientific quality standard for designing, conducting,
recording and reporting trials that involve the
participation of human subjects.
Compliance with this standard provides public assurance
that the rights, safety and well-being of trial subjects are
protected
Objective: ICH GCP Guideline is to provide a unified
standard for the European Union (EU), Japan and the
United States to facilitate the mutual acceptance of
clinical data by the regulatory authorities
2. THE PRINCIPLES OF ICH GCP
Clinical trials should be conducted in accordance
with the ethical principles
The rights, safety, and well-being of the trial subjects
are the most important considerations
Clinical trials should be scientifically sound, and
described in a clear, detailed protocol.
The medical care given to, and medical decisions
made on behalf of, subjects should always be the
responsibility of a qualified physician

the sponsor except for those SAEs that identifies as not needing
immediate reporting
11. Premature Termination or Suspension of a Trial :
If the investigator terminates without prior agreement of the sponsor,
the investigator should inform the institution and should provide the
sponsor and the IRB/IEC a detailed written explanation of the
termination or suspension.
If the sponsor terminates investigator/institution should promptly
inform the IRB/IEC and provide the IRB/IEC a detailed written
explanation of the termination or suspension
If the IRB/IEC terminates or suspends its approval the
investigator/institution should promptly notify the sponsor and
provide the sponsor with a detailed written explanation of the
termination or suspension
10. 12). Final Report by Investigator:

31. Introduction
Designed primarily to increase scientific knowledge about
disease and condition(physical and socio-behavioural)
It includes their detection, cause and strategies for health
promotion, prevention of disease
34. ICMR
The Indian Council of Medical Research (ICMR), the
apex body in India for the formulation, coordination and
promotion of biomedical research, is one of the oldest and
largest medical research bodies in the world. The ICMR is
funded by the Government of India through the
Department of Health Research, Ministry of Health and
Family Welfare
The Council's research priorities coincide with National
health priorities such as control and management of
communicable diseases
35. Background
Second World War (1939-45) trial of German
medical practitioners accused of conducting
experiments on human participants without their
consent and exposing them to grave risk of death
Thus, the first International Statement on the ethics of
medical research using human subjects namely, the
Nuremberg Code was formulated in 1947
In 1948, Universal Declaration of Human Rights
(adopted by the General Assembly of the United
Nations) expressed concern about rights of human
beings being subjected to involuntary maltreatment.
36. In 1966, the International Covenant on Civil and Political
Rights specifically stated, ‘No one shall be subjected to
torture or to cruel, inhuman or degrading treatment or
punishment. In particular, no one shall be subjected
without his consent to medical or scientific treatment.’
In February 1980, the Indian Council of Medical
Research released a ‘Policy Statement on Ethical
Considerations involved in Research on Human Subjects’
for the benefit of all those involved in clinical research in
India
37. In 1982, the World Health Organisation (WHO) and the
CIOMS issued the ‘Proposed International Guidelines for
Biomedical Research involving Human Subjects
38. Governing body
The Governing Body of the Council is presided over by
the Union Health Minister
Assisted by a series of Scientific Advisory Groups, Scientific
Advidsory Committees, Expert Groups, Task Forces,
Steering Committees etc. which evaluate and monitor
different research activities of the Council.
39. General consideration
1.The purpose of such research is that it should be directed
toward the increase of knowledge about the human
condition
2. Such research is conducted under conditions that no
person or persons become a mere
3.such research must be subjected to a regime of evaluation at
all stage of the proposal
40. GENERAL PRINCIPLE
1).Principle of essentiality : mean for the benefit of all
members of the human species
2).Principle of voluntariness ,informed consent and
community agreement:
Where any such research entails treating any community or
group of persons as a research participant, these principles
of voluntariness and informed consent shall apply
41. 3.Principle of non expolitation: research participants
are remunerated for their involvement in the research or
experiment, each research shall include an in built
mechanism for compensation for the human participants
either through insurance cover or any other appropriate
means to cover all foreseeable and unforseeable risk
4. Principle of privacy and confidentiality: where the
identity and records of the human participants of the
research or experiment are confidential
5.Principle of precaution and risk minimization:
To ensure that the research participants and those affected
by it including community are put to the minimum risk
42. 6).Principle of professional competence: The research
is conducted by qualified person who act with total integrity
7). Principle of accountability and transparancy:
Whereby the research or experiment will be conducted in a
fair, honest,impartial and transparent manner
43. ETHICAL REVIEW PROCEDURES
It is mandatory that all proposals on biomedical research
involving human participants should be cleared by an
appropriately constituted Institutional Ethics Committee
(IEC), also referred to as Institutional Review Board (IRB),
Ethics Review Board (ERB) and Research Ethics Board
(REB) in other countries, to safeguard the welfare and the
rights of the participants
They have the responsibility of regular monitoring of the
approved programmes to foresee the compliance of the
ethics during the period of the project
44. BASIC RESPONSIBILITIES

before ethical review is taken up
The IEC’s member-secretary or secretariat shall screen the
proposals for their completeness and depending on the risk
involved categorise them into three types, namely,
exemption from review, expedited review and full review
47. 1)Exemtion from review: Proposals which present less
than minimal risk fall under this category
2)Expedited Review: The proposals presenting no more
than minimal risk to research participants may be
subjected to expedited review.
3).Full Review: All research presenting with more than
minimal risk, proposals/ protocols which do not qualify for
exempted or expedited review and projects that involve
vulnerable population and special groups shall be subjected
to full review by all the members

through a previously scheduled agenda, amended wherever
appropriate
55. General ethical issue
Alltheresearchinvolvinghumanparticipantsshouldbeconductedin
accordance with the four basic ethical principles, namely autonomy
(respect for person / participant) beneficence, non-maleficence (do
noharm)andjustice
The Principal Investigator is the person responsible for not only
undertakingresearchbutalsoforobservanceoftherights,healthand
welfareoftheparticipants
56. INFORMED CONCENT PROCESS
Informed consent protects the individual’s freedom of
choiceandrespectforindividual
Adequate information about the research is given in a
simple and easily understandable unambiguous language
in a document known as the Informed Consent Form
withParticipant/PatientInformationSheet
57. COMPENSATION FOR PARTICIPATION
During the period of research if the participant requires
treatment for complaints other than the one being studied
necessary free ancillary care or appropriate referrals may
be provided
All payments, reimbursement and medical services to be
provided to research participants should be approved by
the IEC
Care should be taken:
when a participant is withdrawn from research for medical
reasons related to the study the participant should get the
benefit for full participation
58. SELECTION OF SPECIAL GROUPS AS RESEARCH
PARTICIPANTS
Pregnant or nursing women:
Pregnant or nursing women should in no circumstances be
the participant 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 participants 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 participants.
59. 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
60. 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.
Persons who are economically or socially disadvantaged
should not be used to benefit those who are better off than
them
61. ESSENTIAL INFORMATION ON CONFIDENTIALITY FOR
PROSPECTIVE RESEARCH PARTICIPANTS
Safeguarding confidentiality:
Data of individual participants can be disclosed under the
following circumstances :
a. only in a court of law under the orders of the presiding
judge

c. in cases of severe adverse reaction may be required to
communicate to drug registration authority
62. COMPENSATION FOR ACCIDENTAL INJURY
Obligation of the sponsor to pay: The sponsor whether
a pharmaceutical company, a government, or an institution,
should agree, before the research begins, in the prior
agreement to provide compensation for any physical or
psychological injury for which participants are entitled or
agree to provide insurance coverage for an unforeseen
injury whenever possible

the Sponsor to the Licensing Authority and to the other
Investigator(s) participating in the study
71. Responsibilities of the Investigator
The Investigator(s) shall be responsible for the conduct of
the trial according to the protocol and the GCP Guidelines
During and following a subject's participation in a trial, the
investigator should ensure that adequate medical care is
provided to the participant for any adverse events.
Investigatons) shall report all serious and unexpected
adverse events to the Sponsor within 24 hours and to the
Ethics Committee that accorded approval to the study
protocol within 7 working days of their occurrence
72. Informed Consent
In all trials, informed, written consent is required to be
obtained from each study subject. The Investigator must
provide information about the study verbally as well as
using a patient information sheet, in a language that is non-
technical and understandable by the study subject. The
Subject's consent must be obtained in writing using an
'Informed Consent Form
A checklist of essential elements to be included in the study
subject's informed consent document as well as a format for
the Informed Consent Form for study Subjects
73. Responsibilities of the Ethics Committee:
It is the responsibility of the ethics committee that reviews
and its approval to a trial protocol to safeguard the rights,
safety and well being of all trial subjects.
The ethics committee should exercise particular care to
protect the rights, safety and well being of all vulnerable
subjects participating in the study, e.g., members of a group
with hierarchical structure (e.g, prisoners, armed forces
personnel, staff and students of medical, nursing and
pharmacy academic institutions), patients with incurable
diseases,
74.
75. Human Pharmacology (Phase I):
The objective of studies in this Phase is the estimation of
safety and tolerability with the initial administration of an
investigational new drug into humans Studies in this Phase
of development usually have non-therapeutic objectives
and may be conducted in healthy volunteers subjects or
certain types of patients
Phase I trials should preferably be carried out by
Investigators trained in clinical pharmacology with access
to the necessary facilities to closely observe and monitor the
Subjects.
76. Studies conducted in phase 1
maximum tolerated
dose Pharmacokinetic
Pharmacodynamic
Early measurement of drug
toxicity
77. Therapeutic exploratory trials (Phase II)
The primary objective of Phase II trials is to evaluate the
effectiveness of a drug for a particular indication or
indications in patients with the condition under study and
to determine the common short-term side-effects and risks
associated with the drug
These studies should be closely monitored.
Doses used in Phase II are usually (but not always) less
than the highest doses used in Phase 1
If the application is for conduct of clinical trials as a part of
multi-national clinical development of the drug, the
number of sites and the patients as well as the justification
for undertaking such trials in India shall be provided to the
Licensing Authority
78. Therapeutic confirmatory trials (Phase III):
Studies in Phase III are designed to confirm the
preliminary evidence accumulated in Phase II that a drug is
safe and effective for use in the intended indication and
recipient population
Studies in Phase III may also further explore the dose-
response relationships(relationships among dose, drug
concentration in blood and clinical response), use of the
drug in wider populations, in different stages of disease, or
the safety and efficacy of the drug in combination with
other drug
79. For new drugs approved outside India,:
Phase III studies need to be carried out primarily to
generate evidence of efficacy and safety of the drug in
Indian patients when used as recommended in the
prescribing information.
Prior to conduct of Phase III studies in Indian subjects,
Licensing Authority may require pharmacokinetic studies
to be undertaken to verify that the data generated in Indian
population is in conformity with the data already generated
abroad
80. Post Marketing Trials (Phase IV):
Post Marketing trials are studies (other than routine
surveillance) performed after drug approval are related to
the approved indication
These trials go beyond the prior demonstration of the
drug's safety, efficacy and dose definition
Phase IV trials include additional drug-drug interaction(s),
dose-response or safety studies and trials designed to
support use under the approved indication, e.g.
mortality/morbidity studies, epidemiological studies etc
81. Studies in special populations:
Geriatrics: Geriatric patients should be included in
Phase III clinical trials
(a) the disease intended to be treated is
characteristically a disease of aging
(b) when there is specific reason to expect that
conditions common in the elderly
(c) when the new drug is likely to alter the geriatric
patient's response (with regard to safety or efficacy)
compared with that of the non-geriatric patient.
82. Paediatrics:
For a drug expected to be used in children, evaluations
should be made in the appropriate age group
If the new drug is intended to treat serious or life-
threatening diseases,lack of data should be justified in
detail.
In cases where there is limited paediatric data at the time of
submission of application - more data in paediatric patients
would be expected after marketing authorisation for use in
children is granted.
