When science takes man as its subject, tensions arise between two values basic to Western society: freedom of scientific inquiry and protection of individual inviolability.... At the heart of this conflict lies an age-old question: When may a society, actively or by acquiescence, expose some of its members to harm in order to seek benefits for them, for others, or for society as a whole?

: Despite its mandate on minimizing harms in clinical trials, the Common Rule provides little guidance as to how IRBs should evaluate risk. The Common Rule and derivative commentaries tend to conceptualize risk review as an expert-based endeavor aimed at an objective and universal evaluation of possible harm; they also have tended to locate risk in the research activity itself rather than in the context of the research. These views of risk conflict with scholarship showing that risk evaluations are socially (...) determined even among experts, that the context of harms can influence how persons evaluate risks, and that forums that approach risk assessment as a technical endeavor bracket from discussion the numerous values that ground risk judgments. Possible reforms are proposed for clinical trial risk review that would render it more inclusive of the different types of risks encountered and more attuned to the priorities of trial subjects.

All major research ethics policies assert that the ethical review of clinical trial protocols should include a systematic assessment of risks and benefits. But despite this policy, protocols do not typically contain explicit probability statements about the likely risks or benefits involved in the proposed research. In this essay, I articulate a range of ethical and epistemic advantages that explicit forecasting would offer to the health research enterprise. I then consider how some particular confidence levels may come into conflict with (...) the principles of ethical research. (shrink)

Objectives: There are indications that institutional review board members do not find it easy to assess the risks and benefits in medical experiments, although this is their principal duty. This study examined how IRB members assessed the risk/benefit ratio of a specific phase II breast cancer clinical trial.Participants and methods: The trial was evaluated by means of a questionnaire administered to 43 members of IRBs at six academic hospitals and specialised cancer centres in the Netherlands. The questionnaire addressed: identification and (...) estimation of inconvenience, toxicity, psychosocial distress, and benefits of trial participation to patients; identification and estimation of benefits to future patients and medical science; assessment of the trial’s RBR; and assessment of its ethical acceptability.Results: Most IRB members expected trial participation to involve fairly or very serious inconvenience, fairly severe to sometimes life-threatening toxicity, and serious psychological and social consequences. Conversely, the perceived likelihood of benefits to patients was modest. Most regarded the study as important, and the balance between risks and benefits to be favourable, and believed that the protocol should be approved. The IRB members’ final judgement on the trial’s ethical acceptability was significantly correlated with their RBR assessment of the protocol.Conclusions: Because most patients who participate in clinical trials hope this will prolong their lives, it is suggested that patient information should better describe the anticipated benefits—for example, the likelihood of prolonging life. This would allow patients to make decisions regarding participation based on realistic expectations. (shrink)
