Impure Hopes

The experiment in China that produced the world's first babies with “edited” DNA comes out of an international research program aimed at producing an HIV cure. An atmosphere of secrecy surrounded this experiment at the edge of the law. Volunteers who signed up for the experiment were HIV-positive tonzghi—gay and bisexual “comrades” already living with closely guarded secrets and conflicted desires. Impure hopes—a mix of heterosexual dreams about reproductive futurity and biotech speculation about an HIV cure—drove the research forward. Volunteers were caught between dreamworlds, harboring hopes that were not entirely their own. The story of these patients is tangled up with CRISPR, a fast and cheap tool for manipulating DNA that contains tantalizing promises of medical breakthroughs for innovators and investors. Speculation in the innovation economy produced an earlier gene-editing experiment in the United States that brought HIV-positive veterans of ACT UP together with biotechnology entrepreneurs. After achieving promising results, a fickle market pushed gene-editing enterprises away from HIV cure research. Building on earlier work about impure science, this article makes an argument against purity to consider the contours of hope in ethically compromised times. Hope demands ongoing articulation work. As powerful political and economic forces threaten to steal queer hopes or simply capitalize on them, it is important to make our own ethical, political, and discursive cuts—to selectively renew some articulations while breaking other connections.

Considerations for designing and implementing combination HIV cure trials: findings from a qualitative in-depth interview study in the United States

Background An increasing number of HIV cure trials involve combining multiple potentially curative interventions. Until now, considerations for designing and implementing complex combination HIV cure trials have not been thoroughly considered. Methods We used a purposive method to select key informants for our study. Informants included biomedical HIV cure researchers, regulators, policy makers, bioethicists, and community members. We used in-depth interviews to generate ethical and practical considerations to guide the design and implementation of combination HIV cure research. We analyzed the qualitative data using conventional content analysis focused on inductive reasoning. Results We interviewed 11 biomedical researchers, 4 community members, 2 regulators, 1 policy researcher, and 1 bioethicist. Informants generated considerations for designing and implementing combination interventions towards an HIV cure, focused on ethical aspects, as well as considerations to guide trial design, benefit/risk determinations, regulatory requirements, prioritization and sequencing and timing of interventions, among others. Informants also provided considerations related to combining specific HIV cure research modalities, such as broadly neutralizing antibodies (bNAbs), cell and gene modification products, latency-reversing agents and immune-based interventions. Finally, informants provided suggestions to ensure meaningful therapeutic improvements over standard antiretroviral therapy, overcome challenges of designing combination approaches, and engage communities around combination HIV cure research. Conclusion The increasing number of combination HIV cure trials brings with them a host of ethical and practical challenges. We hope our paper will inform meaningful stakeholder dialogue around the use of combinatorial HIV cure research approaches. To protect the public trust in HIV cure research, considerations should be periodically revisited and updated with key stakeholder input as the science continues to advance.

Interests of the Non-Human Primate Models for HIV Cure Research

Non-human primate (NHP) models are important for vaccine development and also contribute to HIV cure research. Although none of the animal models are perfect, NHPs enable the exploration of important questions about tissue viral reservoirs and the development of intervention strategies. In this review, we describe recent advances in the use of these models for HIV cure research and highlight the progress that has been made as well as limitations using these models. The main NHP models used are (i) the macaque, in which simian immunodeficiency virus (SIVmac) infection displays similar replication profiles as to HIV in humans, and (ii) the macaque infected by a recombinant virus (SHIV) consisting of SIVmac expressing the HIV envelope gene serving for studies analyzing the impact of anti-HIV Env broadly neutralizing antibodies. Lessons for HIV cure that can be learned from studying the natural host of SIV are also presented here. An overview of the most promising and less well explored HIV cure strategies tested in NHP models will be given.

Ethics of HIV cure research: an unfinished agenda

Background The pursuit of a cure for HIV is a high priority for researchers, funding agencies, governments and people living with HIV (PLWH). To date, over 250 biomedical studies worldwide are or have been related to discovering a safe, effective, and scalable HIV cure, most of which are early translational research and experimental medicine. As HIV cure research increases, it is critical to identify and address the ethical challenges posed by this research. Methods We conducted a scoping review of the growing HIV cure research ethics literature, focusing on articles published in English peer-reviewed journals from 2013 to 2021. We extracted and summarized key developments in the ethics of HIV cure research. Twelve community advocates actively engaged in HIV cure research provided input on this summary and suggested areas warranting further ethical inquiry and foresight via email exchange and video conferencing. Discussion Despite substantial scholarship related to the ethics of HIV cure research, additional attention should focus on emerging issues in six categories of ethical issues: (1) social value (ongoing and emerging biomedical research and scalability considerations); (2) scientific validity (study design issues, such as the use of analytical treatment interruptions and placebos); (3) fair selection of participants (equity and justice considerations); (4) favorable benefit/risk balance (early phase research, benefit-risk balance, risk perception, psychological risks, and pediatric research); (5) informed consent (attention to language, decision-making, informed consent processes and scientific uncertainty); and (6) respect for enrolled participants and community (perspectives of people living with HIV and affected communities and representation). Conclusion HIV cure research ethics has an unfinished agenda. Scientific research and bioethics should work in tandem to advance ethical HIV cure research. Because the science of HIV cure research will continue to rapidly advance, ethical considerations of the major themes we identified will need to be revisited and refined over time.

Ethical and Practical Considerations for Cell and Gene Therapy Toward an HIV Cure: Findings from a Qualitative In-Depth Interview Study in the United States

Background: HIV cure research involving cell and gene therapy has intensified in recent years. There is a growing need to identify standards, safeguards, and protections to ensure cell and gene therapy HIV cure research remains ethical and acceptable to as many stakeholders as possible as it advances on a global scale.Methods: To elicit ethical and practical considerations to guide cell and gene therapy HIV cure research, we implemented a qualitative, in-depth interview study with three key stakeholder groups in the United States: 1) biomedical HIV cure researchers, 2) bioethicists, and 3) community stakeholders. Interviews were transcribed verbatim. We applied conventional content analysis focused on inductive reasoning to analyze the rich qualitative data and derive key ethical and practical considerations related to cell and gene therapy towards an HIV cure.Results: We interviewed 13 biomedical researchers, 5 community members, and 1 bioethicist. Informants generated considerations related to: perceived benefits of cell and gene therapy towards an HIV cure, perceived risks, considerations necessary to ensure an acceptable benefit/risk balance, cell and gene therapy strategies considered unacceptable, additional ethical considerations, considerations for first-in-human cell and gene therapy HIV cure trials. Informants also proposed important safeguards to developing cell and gene therapy approaches towards an HIV cure, such as the importance of mitigating off-target effects, mitigating risks associated with long-term duration of cell and gene therapy interventions, and mitigating risks of immune overreactions.Conclusion: Rapidly evolving cell and gene therapy towards an HIV cure is accompanied by a host of ethical and practical challenges. To minimize risks to potential participants and facilitate the translation of scientific advancements from the bench to the clinic, cell and gene therapy HIV cure research must be thoughtfully developed and implemented. To protect the public trust in cell and gene therapy HIV cure research, ethical and practical considerations should be periodically revisited and updated as the science continues to evolve.
