One of the key ethical requirements for biomedical research is that it have an acceptable risk-benefit profile (Emanuel, Wendler, and Grady 2000). The International Conference of Harmonization guidelines mandate that clinical trials should be initiated and continued only if “the anticipated benefits justify the risks” (1996). Guidelines from the Council for International Organizations of Medical Sciences state that biomedical research is acceptable only if the “potential benefits and risks are reasonably balanced” (2002). U.S. federal regulations require that the “risks to (...) subjects” be “reasonable in relation to anticipated benefits, if any, to subjects and the importance of the knowledge” to be gained from the ..

Modern antiretroviral therapies are capable of suppressing HIV in the bloodstream to undetectable levels. Nonetheless, people living with HIV must maintain lifelong adherence to ART to avoid the re-emergence of the infection. So despite the existence and efficacy of ART, there is still substantial interest in development of a cure. But HIV cure trials can be risky, their success is as of yet unlikely, and the medical gain of being cured is limited against a baseline of ART access. The medical (...) prospect associated with participation in cure research thus look poor. Are the risks and burdens that HIV cure research places on participants so high that it is unethical, at present, to conduct it? In this paper, I answer ‘no’. I start my argument by describing a foundational way of thinking about the ethical justification for regulatory limits on research risk; I then apply this way of thinking to HIV cure trials. In offering this analysis, I confine my attention to studies enrolling competent adults and I also do not consider risks research may pose to third parties or society. Rather, my concern is to engage with the thought that some trials are so risky that performing them is an ethically unacceptable way to treat the participants themselves. I reject this thought and instead argue that there is no level of risk, no matter how high, that inherently mistreats a participant. (shrink)

Most medical research and a substantial amount of non-medical research, especially that involving human participants, is governed by some kind of research ethics committee (REC) following the recommendations of the Declaration of Helsinki for the protection of human participants. The role of RECs is usually seen as twofold: firstly, to make some kind of calculation of the risks and benefits of the proposed research, and secondly, to ensure that participants give informed consent. The extent to which the role of the (...) REC includes the former is not uncontroversial. Indeed, the most prevalent debate on the role of RECs sees liberals and strong paternalists arguing over the importance of informed consent given by competent agents versus the significance of making benevolent decisions on behalf of others. On the one hand, liberals argue for the rights of competent adults to decide for themselves the kinds and extents of risks to which they wish to expose themselves. On the other hand, proponents of strong paternalism raise concerns about the likelihood of participants being able to truly understand the complex data involved in research. They support a role for RECs in which they exercise duties of benevolence towards patients and participants by limiting the extent to which they can be exposed to significant, permanent and irreversible harms. In this paper, we will argue that when it comes to decisions about risk it is neither possible nor desirable for RECs to adopt either role. (shrink)

Risk–benefit assessment is a routine requirement for research ethics committees that review and oversee biomedical research with human subjects. Nevertheless, it remains unclear how to weigh and balance risks to research participants against the social benefits that flow from generating biomedical knowledge. In this article, we address the question of whether there are any reasonable criteria for defining the limit of permissible risks to individuals who provide informed consent for research participation. We argue against any a priori limit to permissible (...) research risks. However, attention to the uncertainty of potential social benefit that can be derived from any particular study warrants caution in exposing prospective research participants to a substantial likelihood of serious harm.
