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)

Consent processes for clinical trials involving HIV prevention research have generated considerable debate globally over the past three decades. HIV cure/eradication research is scientifically more complex and consequently, consent processes for clinical trials in this field are likely to pose a significant challenge. Given that research efforts are now moving toward HIV eradication, stakeholder engagement to inform appropriate ethics oversight of such research is timely. This study sought to establish the perspectives of a wide range of stakeholders in HIV treatment (...) and research to inform consent processes for cure research. In total, 68 South African stakeholders participated in two qualitative research modalities. In-depth interviews were conducted with a purposive sample of 42 individuals - audiotaped with consent. Twenty-six stakeholders participated in three focus group discussions. Thematic analysis of transcribed IDIs and FGDs was conducted. The majority of respondents indicated that there could be unique challenges in HIV cure research requiring special attention. In particular, given the complexity of cure science, translation of concepts into lay language would be critical for potential participants to adequately appreciate risks and benefits in early phase research with experimental interventions. Furthermore, to aid understanding of risks and benefits against a background of desperation for a cure, specially trained facilitators would be required to assist with a psychological assessment prior to consent to avoid curative misconceptions. Long-term participant engagement to assess durability of a cure would mean that the consent process would be prolonged, necessitating annual re-consent. Building trust to maintain such long-term relationships would be critical to retain study participants. Unique consent requirements for cure research in South Africa would include significant efforts to maximise understanding of trial procedures, risks and the need for long-term follow-up. However, the psychological dimension of cure must not be underestimated. Beyond an understanding of cure science, the emotional impact of HIV cure advances the discourse from cure to healing. Consequently, the consent process for cure research would need to be enhanced to include psychological support and counselling. This has several important implications for research ethics review requirements for consent in HIV cure research. (shrink)

Despite existing international, regional and national guidance on how to obtain valid consent to health-related research, valid consent remains both a practical and normative challenge. This challenge persists despite additional evidence-based guidance obtained through conceptual and empirical research in specific localities on the same subject. The purpose of this paper is to provide an account for why, despite this guidance, this challenge still persist and suggest conceptual resources that can help make sense of this problem and eventually mitigate it’. This (...) paper argues that despite the existence of detailed official guidance and prior conceptual and empirical research on how to obtain valid consent, the question of ‘how to obtain and ascertain valid consent to participation in health-related research’ cannot always be fully answered by exclusive reference to pre-determined criteria/guidance provided by the guidelines and prior research’. To make intelligible why this is so and how this challenge could be allayed, the paper proposes six concepts. The first five of these are intended to account for the persistent seeming inadequacies of existing guidelines. These are fact-skepticism; guideline insufficiency; generality; context-neutrality and presumptiveness. As an outcome of these five, the paper analyzes and recommends a sixth, called bioethical reflexivity. Bioethical reflexivity is reckoned as a handy tool, skill, and attitude by which, in addition to guidance from context-specific research, the persisting challenges can be further eased. Existing ethical guidelines on how to obtain valid consent to health-related research are what they ought to be – general, presumptive and context-neutral. This explains their seeming inadequacies whenever they are being applied in concrete situations. Hence, the challenges being encountered while obtaining valid consent can be significantly eased if we appreciate the guidelines’ nature and what this means for their implementation. There is also a need to cultivate reflexive mindsets plus the relevant skills needed to judiciously close the unavoidable gaps between guidelines and their application in concrete cases. This equally applies to the gaps which cannot be filled by reference to additional guidance from prior conceptual and empirical research in specific contexts. (shrink)
