The Ethics CommitteeThe Ethics Committee
• The Ethics review systems are important societal mechanisms involved in the protection of human subjects. Their work should be characterized by:
– Competence of members as per requirements– Quality of the implementation of regulations and
policies– Transparency of procedures– Consistency in review both at the Ethics Committee
level and between committees– Independence from all those having an interest in the
research

Need to Review Research ProtocolsNeed to Review
Research Protocols
… 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.
Helsinki Declaration, B13

Respect for Persons FirstRespect for Persons First
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.
Helsinki Declaration, A5

Respect for Persons FirstRespect for Persons First
Does it still hold true that respect for individuals will
still come firstwhen a deadly epidemic
hits the country?
… and what happens then with ethics review?

1. Scientific Design and Conduct of the Study

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.
Helsinki Declaration, B11 and GCP 2.3
10
Scientific Design and Conduct of the StudyScientific Design and Conduct of the Study
• The evaluation of the scientific merits of
the trial are part of the mandate of the
ethics committee (GCP 3.2.1)
• Clinical trials should be scientifically
sound, and described in a clear, detailed
protocol. (GCP 2.5)
11
Please NotePlease Note
• Even if the evaluation of the science is clearly a function of the Ethics Committee, if a committee feels it does not have all of the necessary expertise around the table, it should ask for external advice or endorse a previous independent scientific evaluation providing enough information is available.
• Ethics committees should have access to the necessary resources to ensure appropriate functioning and access to external consultation as needed.
12
Please NotePlease Note
• A scientifically sound protocol which respects all ethical requirements may not be allowed to proceed for other reasons.
• For example, a hospital may not wish to see a novel expensive treatment introduced through a research project if there exists a satisfactory treatment far less expensive.
13
Scientific Design and Conduct of the StudyScientific Design and Conduct of the Study
The Ethics Committee should consider:
• the appropriateness of the study design in relation to the
objectives of the study (is this design capable of
answering the research question?)
• the statistical methodology (including sample size
calculation), and
• the potential for reaching sound conclusions with the
smallest number of research participants;
14
Scientific Design and Conduct of the StudyScientific Design and Conduct of the Study
• the nature, magnitude and probability of the risks
and benefits, as well as ways to minimize risks
and maximize benefits
• the justification of predictable risks and
inconveniences weighed against the anticipated
benefits for the research participants and the
concerned communities;
15
Scientific Design and Conduct of the StudyScientific Design and Conduct of the Study
• the justification for the use of control arms;
– Will placebo be used? Is it justified?
• criteria for prematurely withdrawing
research participants;
• criteria for suspending or terminating the
research as a whole;
16
Clinical EquipoiseClinical Equipoise
•“… at the start of the trial, there must be a state of genuine equipoise regarding the merits of the regimens to be tested, and the trial must be designed in such a way as to make it reasonable to expect that, if it is successfully conducted, clinical equipoise will be disturbed.“
Freedman, B. Equipoise and the Ethics of Clinical Research,
NEJM, 1987, 312, 141-145
17
An Ideal Lost?An Ideal Lost?• Clinical Equipoise embodied a conception of justice
which was affordable in developed countries• As research moved in developing countries, the use of
control arms, especially using placebo, became more common, even when the existence of clinical equipoise was impossible to argue
• The justification for control arms is now governed by concepts like :– Established medical intervention (CIOMS)– Existing proven therapy (Helsinki)– The non-availability of a suitable control for economic reasons
should not discharged the sponsor of creating a situation of genuine Clinical Equipoise
18
Scientific Design and Conduct of the StudyScientific Design and Conduct of the Study
• the adequacy of provisions made for monitoring and auditing the conduct of the research, including the constitution of a data safety monitoring board (DSMB);
• the adequacy of the site, including the supporting staff, available facilities, and emergency procedures;
• the manner in which the results of the research will be reported and published;

Recruitment and Retention of Research Participants
Recruitment and Retention of Research Participants
• the characteristics of the population from
which the research participants will be
drawn (including gender, age, literacy,
culture, economic status, and ethnicity);
21
Recruitment and Retention of Research Participants
Recruitment and Retention of Research Participants
• Inclusion and exclusion criteria– Should ensure the protection of vulnerable people– Should ensure the just distribution of research risks
and benefits
– Should not automatically leave out populations
susceptible to benefit from research results (pregnant
woman, children, incompetent) unless the risk is
disproportionate since the new treatment could not be
applied to them because they were not part of the trial
22
Recruitment and Retention of Research Participants
Recruitment and Retention of Research Participants

recruitment is to be conducted;
• the means by which full information is to
be conveyed to potential research
participants or their representatives;
