Recommendations from Thai stakeholders about protecting HIV remission ('cure') trial participants: report from a participatory workshop

'It is scary to pause treatment': perspectives on HIV cure-related research and analytical treatment interruptions from women diagnosed during acute HIV in Durban, South Africa

BACKGROUND

HIV remains a major challenge in KwaZulu-Natal, South Africa, particularly for young women who face disproportionate risks and barriers to prevention and treatment. Most HIV cure trials, however, occur in high-income countries.

OBJECTIVE

To examine the perspectives of young women diagnosed with acute HIV in a longitudinal study, focusing on their perceptions on ATI-inclusive HIV cure trials and the barriers and facilitators to participation.

MATERIALS AND METHODS

Between October 2022 and February 2024, we conducted closed-ended surveys and in-depth interviews with 20 women aged 19-33 living with HIV, who were willing but ineligible or unable to participate in an HIV cure trial.

RESULTS

Many participants reported mental health challenges, including major depression (40%), moderate to severe anxiety (35%), and low self-esteem (35%). While women diagnosed during acute HIV supported pausing antiretroviral treatment (ART) during analytical treatment interruption (ATI) to advance HIV cure research, concerns about health risks and HIV-related stigma were significant barriers to enrollment. Trust in the research team and close monitoring were seen as positive factors, while fears around sharing of HIV/ATI status and transmission to sex partners complicated decision-making. Participants expressed a need for psychological counseling and access to community resources to manage ATI-related stressors.

CONCLUSIONS

Understanding women's perspectives on HIV cure research, especially ATI trials, is vital. Building trust and addressing psychosocial challenges through a healing-centered approach can facilitate trial participation. Socio-behavioral research before and during HIV cure trials will be essential to inform participant-centered protocol design.

Lessons Learned in Eliciting Systematic Participant Perspectives in a Combination HIV Cure Research Trial

Current trials toward an HIV cure involve combination strategies aimed at achieving durable antiretroviral treatment (ART)-free viral control or HIV elimination, many relying on analytical treatment interruptions (ATIs) to evaluate efficacy. Given the physical, psychosocial, and interpersonal risks associated with ATIs, it is critical to monitor participants' experiences so that support can be provided when needed. While qualitative approaches have been used in similar settings, we designed and implemented a series of short, closed-ended participant surveys in the University of California, San Francisco-amfAR trial, a single-arm multi-intervention HIV cure-related trial with an extended ATI. Surveys were administered at relevant trial timepoints to capture participants' (n = 10) perspectives and experiences. These included their understanding of the trial, motivations, expectations, perceived risks, benefits, and burdens of trial participation, as well as their perspectives on restarting ART and partner protections. We describe these data using descriptive statistics and summarize lessons learned from implementing quantitative surveys in this complex trial. Our data indicate that all respondents understood the scientific goals and requirements of participating in the trial. Most were motivated to help advance research but many expressed anxiety about participating. During the trial, respondents had limited side effects, discomfort, and trial burnout. Those who completed surveys at ART restart reported mixed (positive and negative) feelings and challenges (e.g., missed doses) when restarting ART. Participants offered various methods for partner protection during ATIs and at ART restart. Many respondents expressed future willingness to participate in a similar HIV cure trial. While the number of respondents was small, these findings are consistent with concerns identified in guidance regarding these types of trials as well as qualitative findings from earlier studies. Moreover, we demonstrated that it is feasible to implement quantitative evaluations of participants' experiences. Such approaches should be implemented in future HIV cure trials to optimize human-centered research implementation.

"They Have to Make an Effort Too": What Decliners Can Teach Us About HIV Cure/Remission-Related Clinical Trials? Results from a French Qualitative Study

Only one study to date has focused on people living with HIV (PLWH) who refused to participate in a HIV cure/remission-related clinical trial (HCCT)-"decliners" hereafter-that included analytical treatment interruption (ATI). Exploring why these persons refuse may provide valuable information to ensure more ethical recruitment and support in HCCTs within the bigger picture of improving HIV cure research. The qualitative component of the AMEP-EHVA-T02/ANRS-95052 study, called AMEP-Decliners, documented the experiences of French PLWH who refused to participate in EHVA-T02/ANRS-VRI07, a phase II randomized, placebo-controlled HCCT with ATI. AMEP-Decliners comprised semi-structured individual interviews with six decliners in two HIV care sites in France between September 2022 and March 2023. The interviews documented their expectations regarding HCCTs, reasons for refusal, and perceived factors that might have led them to participate. Audio files were transcribed, and an inductive thematic analysis was performed. Surprisingly, the main reason for refusal was not ATI but the trial monitoring. Besides the frequency of appointments, respondents emphasized the incompatibility with their active life. One underlying reason for refusal was that participating would have meant "break[ing] the carefree attitude about the disease," reflecting the substantial psychological burden associated with participation. Finally, respondents perceived that the trial's clinical team did not sufficiently recognize their "normal life" and the level of commitment required to participate, leading them to call for greater involvement by the team: "they have to make an effort too." Results from decliners' discourses highlighted that two levels of commitment to participation must be considered when developing HCCTs: psychological burden and logistical constraints. We suggest allowing home examinations and flexible appointment times, prioritizing face-to-face invitations in order to address the psychological burden associated with HCCT participation, and explaining the reasons for monitoring constraints when they cannot be alleviated. Further studies are necessary to confirm our results.

The Importance of Social Engagement in the Development of an HIV Cure: A Systematic Review of Stakeholder Perspectives

As research into the development of an HIV cure gains prominence, assessing the perspectives of stakeholders becomes imperative. It empowers stakeholders to determine priorities and influence research processes. We conducted a systematic review of the empirical literature on stakeholder perspectives. PubMed, Embase, Web of Science, and Scopus were searched for empirical, peer-reviewed articles, published before September 2022. Our analysis of 78 papers showed that stakeholders could be divided into three categories: people with HIV, key populations, and professionals. Following thematic synthesis, two main themes were distinguished: stakeholders' perspectives on HIV cure research and stakeholders' perspectives on HIV cure. Research on perspectives on HIV cure research showed that stakeholders' hypothetical willingness to participate (WTP) in HIV cure research was relatively high, while actual WTP was found to be lower. Studies also identified associated (individual) characteristics of hypothetical WTP, as well as facilitators and barriers to hypothetical participation. Additionally, we reported research on experiences of actual HIV cure research participation. Our analysis of stakeholder perceptions of HIV cure showed that most stakeholders preferred a cure that could eliminate HIV and outlined positive associated impacts. Furthermore, we observed that most included studies were conducted among PWHIV, and in the Global North. To empower stakeholders, we recommend that future research include an even greater diversity of stakeholders and incorporate theories of behavior to further explore how stakeholders decide to meaningfully engage in every stage of HIV cure research.

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.
