Perceptions of HIV cure research among people living with HIV in Australia

'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.

The expected impact of a cure for HIV among people with HIV and key populations

BACKGROUND

This study explored the expected impact of two hypothetical HIV cure scenarios on quality of life, sexual satisfaction, and stigma among people with HIV and key populations (i.e., partners and communities of people with HIV and men who have sex with men without HIV) in the Netherlands.

METHODS

A cross-sectional survey was conducted among people with HIV and key populations from October 2021 until June 2022. We assessed quality of life, sexual satisfaction, and stigma using linear regression and mixed models to compare participants' current situation with two hypothetical HIV cure scenarios: HIV post-intervention control, where HIV is suppressed without the need for ongoing antiretroviral treatment, but the viral reservoir is expected to persist, and HIV elimination, where HIV is completely removed from the body.

RESULTS

Our findings show that people with HIV (n = 222) expect improved quality of life and sexual satisfaction, as well as reduced stigma, compared to their current situation following both post-intervention control and elimination. Key populations (n = 495) similarly expect improvements for both HIV cure scenarios, except no expected improvement was found for quality of life following post-intervention control. Participants aged 18 to 34 anticipate greater improvements from both cure scenarios than those over 34.

CONCLUSIONS

Both people with HIV and key populations without HIV expect an HIV cure to have a positive impact on quality of life, sexual satisfaction, and stigma. This impact is expected not only for HIV elimination but also for HIV post-intervention control, the development of which appears more feasible.

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.

"Sometimes They Exclude Us because of Our Age-That's Not Right": Perceptions of HIV Cure Research Among Diverse Long-Term Survivors in the United States

HIV cure research has advanced, utilizing analytical treatment interruption (ATI) as a research tool alongside therapeutic strategies such as latency-reversing agents, block and lock strategies, immune-based therapies, cell and gene therapies, and combination approaches to overcome viral persistence. While promising, participation in cure trials remains limited, particularly for long-term survivors (LTS) who have lived with HIV for decades. Many LTS are willing to participate but face barriers such as age-based exclusions, comorbidities, and trial design constraints. With over half of the people with HIV in the United States aged 50 or older, addressing these barriers is crucial to designing inclusive, equitable, and representative cure trials. We conducted 32 semi-structured interviews with LTS of HIV, aged 60 years and older, recruited through community-based organizations and research networks across the United States. Participants were diverse in age, sex, gender, race, and ethnicity. We transcribed, anonymized, and analyzed interviews thematically. Most participants expressed a willingness to participate in HIV cure research, driven by a sense of responsibility and hope for future generations. However, concerns were raised about age-based exclusions from HIV cure trials, which many participants viewed as unjust given their long-term experience with HIV and commitment to finding a cure that could potentially benefit people of their age. Additional concerns included the risks of ATIs, such as viral rebound and the development of viral resistance, along with logistical challenges, including transportation and invasiveness of certain procedures. Despite these barriers, most LTS indicated they would participate in HIV cure trials if researchers addressed their concerns about safety, accessibility, and inclusion. LTS emphasized the need for transparent communication, clear informed consent, and flexible trial designs that accommodate their needs. By addressing these concerns, researchers can engage LTS more meaningfully in HIV cure research, enriching the field and promoting more inclusive and ethical study designs.

Exploring Stigma and Self-Image: Mixed-Methods Insights from HIV Cure-Related Research Participants Undergoing Analytical Treatment Interruptions

This mixed-methods study explored self-image among people with HIV participating in an HIV cure-related study involving analytical treatment interruptions (ATIs). Using both quantitative and qualitative approaches, we described how self-image emerged across study participation, focusing on internalized stigma, emotional strengths, and the psychosocial dimensions of study participation. Data come from the SCOPE-ATI substudy (NCT00187512) of the University of California San Francisco SCOPE cohort (NCT04359186). Quantitative data were collected at three timepoints: pre-ATI (n = 15), post-ATI (n = 12), and end of the study (n = 14). We observed a general decline in self-image scores over time. However, participants maintained a moderately high agreement with statements about contributing to reducing HIV stigma through their involvement in the study. Qualitative interviews were collected pre-ATI (n = 11), during ATI (n = 8), and post-ATI (n = 6). Qualitative findings revealed two major themes shaping self-image: (1) experiencing and reconciling internalized HIV stigma and (2) self-evaluations in relation to life purpose. Many participants expressed disappointment at having to resume antiretroviral therapy, viewing it as a reminder of their HIV status and its associated stigma. Nevertheless, some found purpose and pride in their participation, motivated by altruistic contributions to improving future HIV control options. The findings highlight the emotional complexities of participating in HIV cure research and underscore the need for psychosocial support throughout ATI studies. While most participants experienced a decline in self-image, some derived meaning and empowerment from their involvement. This study suggests that addressing emotional well-being and reinforcing participants' contributions to science can enhance their experience in future research.

Missing voices: building women living with HIV's meaningful engagement in HIV clinical and cure research

Women living with HIV are consistently under-represented in HIV clinical trials, including cure trials. Little is known about how cisgender women living with HIV in Australia perceive HIV cure research, their level of trust in research institutions/staff, and factors salient to participation in HIV cure trials. Semi-structured interviews were conducted with women living with HIV and clinicians working with women living with HIV to investigate motivations and barriers to gender-equitable representation in HIV clinical research. Participant motivations for participation included altruistic desires to benefit younger women, and to optimise resulting interventions. Women living with HIV expressed optimism that a cure would dispel HIV-related stigma and brings about substantial material improvement to their lives. Reluctance to participate related to concerns regarding potential side-effects, antiretroviral treatment interruption, and impacts on fertility. Unfamiliarity with trials, confidentiality concerns and logistical difficulties were also cited. Lastly, onerous eligibility criteria, clinicians' assumptions about women's willingness and ability to meaningfully provide consent to participation were cited as barriers which could be addressed. Bolstering women's participation in HIV cure research requires consideration of factors relating to reproductive health, analytical treatment interruption, and recruitment. Engaging women living with HIV in trial design and promotion may help overcome these issues.

Participant experiences in a combination HIV cure-related trial with extended analytical treatment interruption in San Francisco, United States

BACKGROUND

There is limited systematic information available about the perspectives of participants enrolled in intensive combination HIV cure-related trials inclusive of an extended analytical treatment interruption (ATI).

OBJECTIVE

To assess and understand experiences of people with HIV involved in a combination HIV cure-related trial with an extended ATI.

METHODS

The trial included five interventions and was followed by an ATI lasting up to 52 wk. From 2022 - 2023, we conducted in-depth interviews with study participants following their extended ATIs. Interviews were audio-recorded, transcribed, and analyzed via conventional thematic analysis.

RESULTS

We interviewed seven participants. The majority were male, White, and non-Hispanic, with a median age of 37 years. Trust in the research team, scientific altruism and hope of becoming a post-intervention controller were key motivators for joining the trial. Interviewees reported being satisfied with their decision to participate in the trial and the extended ATI. Most recounted feelings of worry related to viral rebound during the ATI. Participants reported both defeat and relief with ART restart. Four faced challenges with protecting partners from HIV during their ATI, such as trying to find out if their partner(s) were using pre-exposure prophylaxis.

CONCLUSIONS

Our findings demonstrate potential improvements for future ATI trial participant experiences, such as more robust resources for psychosocial support and partner protections. Dedicating greater effort to understanding participant ATI experiences can inform the design of future participant-centered HIV cure trial protocols.

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.

A partner protection package for HIV cure-related trials involving analytical treatment interruptions

Analytical treatment interruptions (ATIs) have become a key methodological approach to evaluate the effects of experimental HIV cure-related research interventions. During ATIs, sex partners of trial participants might be at risk of acquiring HIV. This risk raises both ethical and feasibility concerns about ATI trials. We propose a partner protection package (P3) approach to address these concerns. A P3 approach would provide guidance to investigators, sponsors, and those who are designing and implementing context-specific partner protections in HIV cure-related trials involving ATIs. The approach would also help assure institutional review boards, trial participants, and communities that ATI trials with a P3 would provide appropriate partner protections. We offer a prototype P3 framework that delineates three basic considerations for protecting participants' sex partners during ATI trials: (1) ensuring the scientific and social value of the ATI and the trial, (2) reducing the likelihood of unintended HIV transmission, and (3) ensuring prompt management of any acquired HIV infection. We outline possible ways of implementing these basic considerations.

"I Would Absolutely Need to Know That My Partner Is Still Going to be Protected": Perceptions of HIV Cure-Related Research Among Diverse HIV Serodifferent Couples in the United States

Most HIV cure studies remain in the early stage of investigation and may carry clinical risks to the participants and, in some cases, their partners. Surprisingly little sociobehavioral research has investigated the perceptions of couples-including HIV serodifferent couples-around HIV cure research, including factors that would influence recruitment and retention in trials. We conducted a qualitative study to explore perceptions of diverse HIV serodifferent partners in the United States. We recruited 10 diverse HIV serodifferent couples (20 participants). We found participants had learned to cope with the reality of HIV, including protections during sex, and ascribed both positive and negative meanings to an HIV cure. Partners expressed concern about each other's health and potentially caring for a sick partner and emphasized the importance of safety when participating in an HIV cure trial. They identified the need for partner protection measures during analytical treatment interruptions (ATIs) as an ethical imperative. Participants recounted experiences of HIV stigma due to being in HIV serodifferent relationships and viewed ATIs as leading to a detectable viral load, which could limit sexual expression, complicate disclosure decision making, and worsen HIV-related stigma. Our study's main contribution is to inform efforts to meaningfully engage diverse HIV serodifferent partners in HIV cure research in the United States. Our data suggest people with HIV make decisions to participate in research based on close ones in their life and underscore the critical importance of acknowledging relationship dynamics in decisions to participate in research.

Willingness of Racially Diverse Young Adults Living with HIV to Participate in HIV Cure Research: A Cross-Sectional Survey in the United States

Nearly half of new HIV cases in the United States are among youth. Little is known about the willingness of young adults living with HIV (YLWH) to participate in HIV cure-related research. In 2021, we recruited 271 YLWH aged 18-29 for an online survey. We asked questions about willingness to participate in HIV cure research, perceived risks and benefits, acceptable trade-offs, and perceptions on analytical treatment interruptions. We conducted descriptive analyses to summarize data and bivariate analyses to explore correlations by demographics. Most respondents (mean age = 26) identified as men (86%) and Black Americans (69%). YLWH expressed high willingness to consider participating in cell- and gene-based approaches (75%) and immune-based approaches (71%). Approximately 45% would be willing to let their viral load become detectable for a period of time during an HIV cure study, 27% would not be willing, and 28% did not know. The social risk most likely to deter participation was the possibility of transmitting HIV to sex partners while off HIV medications (65% of respondents would be deterred a great deal or a lot). Compared to the 25-29 age group (n = 192), the 18-24 age group (n = 79) was more likely to indicate that having to disclose HIV status would matter a great deal in considering participation in HIV cure research (38% vs. 21%, p = .003). Inclusion and engagement of YLWH are critical for advancing novel HIV curative agents. Our article concludes with possible considerations for engaging YLWH in HIV cure research. Physical, clinical, and social risks will need to be kept to a minimum, and research teams will need to proactively mitigate the possibility of transmitting HIV to sex partners while off HIV medications.

'With this study, we have hope that something is coming': community members' perceptions of HIV cure-related research in Durban, South Africa - a qualitative focus group study

BACKGROUND

Developing a cure for HIV remains a global scientific priority. In 2022, the Females Rising through Education, Support and Health (FRESH) cohort launched an HIV cure-related trial involving an analytical treatment interruption (ATI) in Durban, South Africa.

OBJECTIVES

To explore community perspectives about HIV cure-related research.

METHODS

Between July-August 2022, we conducted three focus groups with community members. We transcribed audio recordings verbatim and used content analysis to analyze the data.

RESULTS

Twenty community members (13 women and 7 men) participated in three focus groups (HIV status not included). Participants viewed HIV cure-related research as a way to address the issue of defaulting on (not taking) HIV treatment. Participants expressed hesitancy around ATIs, since these contradict longstanding treatment adherence messages. Participants shared concerns around the risk of side effects from experimental interventions balanced against potential efficacy. They advocated for trial participants to have the right to decide whether to inform their sex partners about their HIV status and ATI participation, rather than research teams making disclosure mandatory. Focus group participants also emphasized the importance of using simple language to explain HIV cure-related research.

CONCLUSIONS

With HIV cure trials set to launch across Africa in the future, there is a critical need to better understand and respond to local community needs and preferences and to adopt this as standard practice prior to regional trial implementation.

HIV cure: an acceptability scientific agenda

PURPOSE OF REVIEW

Recent years have seen major investments into HIV cure research, seeking a permanent cure or remission. The purpose of this review is to consider how this important research agenda could be broadened to include issues of acceptability and appropriateness for different populations.

RECENT FINDINGS

We discuss how the definitions of cure such as functional cure (remission) or complete cure (viral elimination) could be interpreted differently by various populations. We also discuss the different methods of cure and the importance of including Africa in cure research to ensure that emerging remedies could be trialled and utilized on the continent that bears the brunt of the AIDS pandemic.

SUMMARY

We propose that the social science research of HIV cure acceptability should be done concurrently with the basic and clinical sciences, to ensure that cure methods consider stakeholder preferences.

Donating One's Body to HIV Cure Research Through Canadian Medical Assistance in Dying: A Case Study

BACKGROUND

Finding a cure for HIV is challenged by persisting reservoirs, the mapping of which necessitates invasive procedures. Inviting people with HIV (PWHIV) at the end of life to donate body specimens post-mortem through research autopsies is a novel approach, raising ethical concerns.

OBJECTIVE

This case study aims to explore the motivations, barriers, and facilitators of a terminally-ill Canadian PWHIV who requested medical assistance in dying (MAID) and expressed interest in donating his body for HIV cure research.

CASE PRESENTATION

An in-depth 3-hour and semi-structured interview was conducted with the participant. The interview transcription was thematically coded to identify motivations and perceived barriers and facilitators to participate in end-of-life HIV cure research. Our analysis identified six themes. Two themes expressed motivations: Collaboration in progress in health and science, seeing cure research as collaboration with professionals; and Opportunity to learn more, mostly about science and health. One theme expressed a barrier: Losing interest in or identification with long-term care research matters, especially those related to the management of long-term care. Three themes expressed by facilitators: Receiving information from professionals one trusts and knows, especially clinical and research teams; Perceiving research procedures as simple, useful, and embedded in care, perceiving clinical, educational, and interpersonal benefits that surpass costs of participation; and Perceiving research as one last way to contribute, that is, feeling useful or give back.

CONCLUSION

Several circumstances facilitated the patient's participation: being a single man, having time to participate, having no strong religious belief, and valuing clear, direct communication. His motivations to participate in HIV cure research were altruistic, and also an experience of working with clinical and research teams. Finally, this perspective highlights HIV cure research participant candidates' need for education about research procedures.

Perceptions of Risks and Benefits of Participating in HIV Cure-Related Research Among Diverse Young Adults Living with HIV in the United States: Qualitative Research Findings

In the United States, young adults have the highest rates of new HIV infections, and are less likely to be aware of their infection, be engaged in care, or achieve HIV viral suppression. As biomedical HIV research increasingly focuses on achieving long-term suppression without antiretroviral therapy (ART) and finding an HIV cure, little is known about perceptions of young adults living with HIV (YLWH) regarding HIV cure research. We recruited a diverse sample of 20 YLWH (18-29 years old) to participate in individual semistructured qualitative interviews to explore knowledge and perceptions of HIV cure research, and motivations and barriers to participation. Most participants had little knowledge of HIV cure research. Motivators of HIV cure research participation included altruism, stigma reduction, and the elimination of the clinical burdens of HIV. Barriers included potential physical side effects, psychological distress, the possibility of disclosure as a result of participating, and the amount of time required to participate. Most participants had concerns about analytic treatment interruptions (i.e., ART interruption to assess HIV remission), and indicated that they would want more frequent laboratory testing and protection for their sex partners during this time. Finally, participants suggested that, if other YLWH are considering participation in cure research, they should first learn as much as possible about the research, and then consider the potential personal benefits and the contribution that they could make to science and their communities. As HIV cure research advances, the participation of YLWH will be critical. Our study provides knowledge about how YLWH view HIV cure research. More sociobehavioral research is needed to ensure that those who are most likely to be the decision-makers and beneficiaries of an HIV cure are included at all levels of research.

Perceptions of HIV cure and willingness to participate in HIV cure-related trials among people enrolled in the Netherlands cohort study on acute HIV infection

Background

People who initiate antiretroviral therapy (ART) during acute HIV infection are potential candidates for HIV cure-related clinical trials, as early ART reduces the size of the HIV reservoir. These trials, which may include ART interruption (ATI), might involve potential risks. We explored knowledge and perception of HIV cure and willingness to participate in cure-related trials among participants of the Netherlands Cohort Study on Acute HIV infection (NOVA study), who started antiretroviral therapy immediately after diagnosis of acute HIV infection.

Methods

We conducted 20 in-depth qualitative interviews with NOVA study participants between October-December 2018. Data were analyzed thematically, using inductive and iterative coding techniques.

Findings

Most participants had limited knowledge of HIV cure and understood HIV cure as complete eradication of HIV from their bodies. HIV cure was considered important to most participants, mostly due to the stigma surrounding HIV. More than half would consider undergoing brief ATI during trial participation, but only one person considered extended ATI. Viral rebound and increased infectiousness during ATI were perceived as large concerns. Participants remained hopeful of being cured during trial participation, even though they were informed that no personal medical benefit was to be expected.

Interpretation

Our results highlight the need for thorough informed consent procedures with assessment of comprehension and exploration of personal motives prior to enrollment in cure-related trials. Researchers might need to moderate their expectations about how many participants will enroll in a trial with extended ATI.

Participant Perspectives and Experiences Following an Intensively Monitored Antiretroviral Pause in the United States: Results from the AIDS Clinical Trials Group A5345 Biomarker Study

The AIDS Clinical Trials Group A5345 study (NCT03001128) included an intensively monitored antiretroviral pause (IMAP), during which participants living with HIV temporarily stopped antiretroviral treatment (ART) in an effort to identify biomarkers that could predict HIV rebound. We evaluated the potential impact of the IMAP on A5345 study participants in the United States by questioning them immediately after the IMAP and at the end of the study. We administered longitudinal sociobehavioral questionnaires to participants following the IMAP when they resumed ART and at the end of the study. We summarized descriptive data from the post-IMAP and end-of-study questionnaires. Open-ended responses were analyzed using conventional content analysis. Reactions to pausing ART involved a mixture of curiosity and satisfaction from contributing to science. All participants indicated adherence with the ART interruption. About half (9/17) of post-IMAP questionnaire respondents reported having sexual partner(s) during the IMAP, and of those, nearly all (8/9) did not find it difficult to use measures to prevent HIV transmission to partners. The majority believed that they benefited from the study, yet some had elevated anxiety following the IMAP and at the end of the study. Most (24/29) respondents who completed the end-of-study questionnaire would recommend the study to other people living with HIV. Our findings underscore the relevance of the psychosocial aspects of participating in studies that involve interruptions of ART. Understanding how participants experience this research is invaluable for informing the design of future research aimed at sustained ART-free virologic suppression.

Facilitators and barriers of women's participation in HIV clinical research in Switzerland: A qualitative study

OBJECTIVES

Women are underrepresented in most HIV clinical trials in Western countries, but their participation remains crucial as the lack of information on sex- and gender-specific effects may hinder the safety and efficacy of antiretroviral treatments. The aim of this study was to identify barriers to and facilitators of women's participation in HIV clinical trials in Switzerland.

METHODS

We conducted semi-structured interviews among 20 women with HIV to explore factors associated with non-participation in clinical trials. The interviewer presented to participants a clinical trial's description and discussed it with them. Lexicometric analysis on transcribed interviews identified three themes and eight sub-themes related to the pros and cons of participation in HIV clinical trials.

RESULTS

Participants evoked mainly decision-making drivers, concerns for women living with HIV and treatment side-effects. They highlighted the need for extensive information provided by trusted healthcare professionals on the research process as central to the decision to enrol in HIV clinical trials. Familial responsibilities were clearly identified as barriers to their participation, but not pregnancy. Additional preoccupations were other health concerns and comorbidities and the consequences of stopping ongoing antiretroviral treatments.

CONCLUSIONS

To overcome the barriers to the participation of women living with HIV in clinical research in Western countries, healthcare professionals and researchers should increase women's research literacy by involving them in the study design and by tailoring clinical trials to their social roles and health concerns. Trust in professionals is a facilitator of enrolment of women living with HIV that should be maintained.

The perceived impact of an HIV cure by people living with HIV and key populations vulnerable to HIV in the Netherlands: A qualitative study

Introduction

When an HIV cure becomes available, it will have consequences for people living with HIV (PLHIV) and key populations who are vulnerable to HIV. This qualitative study aimed to explore the perceived impact of two HIV cure scenarios (post-treatment control when HIV is suppressed without the need for ongoing antiretroviral treatment (ART) and complete HIV elimination) on the quality of life of PLHIV and key populations living without HIV in the Netherlands.

Methods

Participants were purposefully sampled from the Amsterdam Cohort Studies, the AGEhIV Cohort Study, the outpatient clinic of the University Medical Centre Utrecht and the Dutch HIV Association to increase variability. Semi-structured in-depth interviews were conducted between October 2020 and March 2021 and thematically analysed.

Results

Of the 42 interviewed participants, 29 were PLHIV and 13 represented key populations (i.e., men who have sex with men and people injecting drugs). Both PLHIV and participants from vulnerable key populations hoped that a cure would result in normalization of their lives by removing the need to disclose HIV, reducing stigma and guilt, increasing independence of ART, and liberating sexual behaviour. Both groups believed only HIV elimination could accomplish this desired impact.

Conclusions

While the post-treatment control scenario seems a more plausible outcome of current HIV cure research, our findings highlight that participants may not perceive it as a true cure. Involvement of PLHIV and vulnerable key populations in devising acceptable and feasible experimental approaches to HIV cure is essential to ensure their future successful implementation.

Diminished Peripheral CD29hi Cytotoxic CD4+ T Cells Are Associated With Deleterious Effects During SIV Infection

Cytotoxic CD4+ T cells (CD4+ CTLs) limit HIV pathogenesis, as evidenced in elite controllers (a subset of individuals who suppress the virus without the need for therapy). CD4+ CTLs have also been shown to kill HIV-infected macrophages. However, little is known about their contribution towards HIV persistence, how they are affected following exposure to immune modulators like morphine, and what factors maintain their frequencies and function. Further, the lack of robust markers to identify CD4+ CTLs in various animal models limits understanding of their role in HIV pathogenesis. We utilized various PBMC samples obtained from SIV infected and cART treated rhesus macaques exposed to morphine or saline and subjected to flow cytometry evaluations. Thereafter, we compared and correlated the expression of CD4+ CTL-specific markers to viral load and viral reservoir estimations in total CD4+ T cells. We found that CD29 could be reliably used as a marker to identify CD4+ CTLs in rhesus macaques since CD29hi CD4+ T cells secrete higher cytotoxic and proinflammatory cytokines following PMA/ionomycin or gag stimulation. In addition, this immune cell subset was depleted during untreated SIV infection. Strikingly, we also observed that early initiation of cART reconstitutes depleted CD29hi CD4+ T cells and restores their function. Furthermore, we noted that morphine exposure reduced the secretion of proinflammatory cytokines/cytotoxic molecules in CD29hi CD4+ T cells. Lastly, increased functionality of CD29hi CD4+ T cells as depicted by elevated levels of either IL-21 or granzyme B hi T Bet+ gag specific responses were linked to limiting the size of the replication-competent reservoir during cART treatment. Collectively, our data suggest that CD4+ CTLs are crucial in limiting SIV pathogenesis and persistence.

Brief Report: Representations and Willingness of People Living With HIV in Switzerland to Participate in HIV Cure Trials: The Case of Gene-Modified Cell Therapies

BACKGROUND

Recent advances made in cell and gene therapies for cancer suggest that they represent plausible strategies to cure HIV. However, the health risks and constraints associated with these therapies require a deeper understanding of the expectations of such treatments among people living with HIV (PLWH).

METHODS

We conducted 15 semistructured in-depth interviews among patients from 2 HIV units in Switzerland. After a conversation about their perceptions of research on HIV therapies, participants were provided with a trial description using a gene-modified cell therapy as a potentially curative approach. They were invited to discuss how they might consider participation in the trial. Content analysis was performed to identify core themes.

RESULTS

Participants perceived the trial as burdensome and uncertain. Most were aware that cure was not guaranteed, and 6 of the 15 considered that they would participate. Two main concerns were expressed about potential participation: (1) the impact on the professional life and fear to be stigmatized because of this and (2) the fact that stopping antiretroviral treatment would challenge the balance currently achieved in their lives. The decision to participate would depend on their understanding of the trial, the availability of sufficient information, and the relationship with health care professionals.

CONCLUSION

Involving PLWH in early stages of research would be crucial to improve their understanding of gene-modified cell therapies. It could also help adapt trials to address key factors, including the anticipation of stigma, which may discourage PLWH from participating in treatment research.

Ethics of HIV and hepatitis B cure research

PURPOSE OF REVIEW

Achieving a cure for HIV or hepatitis B virus (HBV) is expected to have a range of salutary effects including eliminating the need for continued treatments, minimizing risk to sexual and injecting partners, reducing prevalence, and decreasing stigma. Nevertheless, conducting research to achieve such laudable goals is necessarily associated with a broad set of ethical challenges. This review aims at describing key findings from selected peer-reviewed literature published in the last 2 years (2018-2019) that enhance understanding of some of these issues.

RECENT FINDINGS

A variety of ethical issues in HIV cure research have been informed by recent conceptual and empirical scholarship. These include: analytical treatment interruptions; attitudes towards participation; responsibilities to nonparticipants; consent and terminology; and selected other issues.

SUMMARY

Understanding of the ethical issues in HIV cure research has been enhanced by sustained normative and empirical scholarship with a range of stakeholders. This work has crucial implications for HBV cure research, but there is also a pressing need for directed work on HBV cure research. In both HIV and HBV cure research, such scholarship promises to help ensure that critically important research efforts are ethically sound.

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.

Transparency, trust and minimizing burden to increase recruitment and retention in trials: a systematic review

OBJECTIVE

To describe patient perspectives on recruitment and retention in clinical trials.

STUDY DESIGN AND SETTING

Systematic review of qualitative studies that reported the perspective of adult patients with any health condition who accepted or declined to participate in clinical trials.

RESULTS

Sixty-three articles involving 1681 adult patients were included. Six themes were identified. Four themes reflected barriers: ambiguity of context and benefit - patients were unaware of the research question and felt pressured in making decisions; lacking awareness of opportunities - some believed health professionals obscured trials opportunities, or felt confused because of language barriers; wary of added burden - patients were without capacity because of sickness or competing priorities; and skepticism, fear and mistrust - patients feared loss of privacy, were suspicious of doctor's motivation, afraid of being a guinea pig, and disengaged from not knowing outcomes. Two themes captured facilitators: building confidence - patients hoped for better treatment, were supported from family members and trusted medical staff; and social gains and belonging to the community - altruism, a sense of belonging and peer encouragement motivated participation in trials.

CONCLUSION

Improving the visibility and transparency of trials, supporting informed decision making, minimizing burden, and ensuring confidence and trust may improve patient participation in trials.

Motivations, barriers and experiences of participants in an HIV reservoir trial

Objectives

We aimed to investigate the motives, barriers and experiences of HIV-STAR study participants. The HIV-STAR study was an analytical HIV treatment interruption trial (ATI) aiming to evaluate the origin of viral rebound, conducted in Ghent, Belgium.

Methods

A mixed-method study was performed among 11 participants of the HIV-STAR study. Two self-administered questionnaires with 32 and 23 items, respectively, assessed motives, barriers and experiences of the research participants. In-depth interviews were conducted to further explore and understand topics that had emerged from these surveys.

Results

Motives of ATI study participants were primarily related to the improvement of their own health perspectives and to their contribution to find an HIV cure. Barriers for ATI participation mostly related to practical issues, such as difficulty in planning study visits. Ten out of 11 participants reported a very high overall satisfaction and were willing to participate in another ATI. This satisfaction was predominantly linked to clear communication and guidance. Invasive sampling during the ATI was less of a burden than anticipated by participants. However, most participants underestimated the emotional impact of HIV treatment interruption, which was associated with feelings of uncertainty and loss of control. Risk of HIV transmission because of viral rebound was also mentioned as burdensome during this phase.

Conclusions

Involvement in an ATI was positively evaluated by HIV-STAR participants. Contributing to HIV cure research outweighed the burden of study participation for most participants. The latter aspects were attenuated by mutual decision making and the experience of empathy from the research team. Still, issues regarding privacy and the psychosocial impact of treatment interruption, including sexuality and HIV transmissibility, should be addressed in a better way.

"I would really want to know that they had my back": Transgender women's perceptions of HIV cure-related research in the United States

Forty-four percent of Black transgender women are living with HIV, and many face challenges with HIV care engagement. An HIV cure has much to offer this population, however little HIV cure-related research has included them. We conducted 19 face-to-face in-depth interviews with 10 Black transgender women living with HIV. Interviews were audio recorded, transcribed verbatim, coded, and analyzed using content analysis. Our interview guide contained three categories: 1) perceptions of HIV cure-related research and participation, 2) perceptions of HIV treatment and treatment interruptions, and 3) considerations for transgender women and HIV cure-related research. Salient themes included skepticism about HIV cure strategies and limited benefits compared with an undetectable viral load. Willingness to interrupt HIV treatment for research was low and linked to being able to go back on the same HIV treatment without consequence when the study ended. Concerns about being a test subject and perceptions of risks versus benefits of various strategies also affected willingness to take part in HIV cure-related research. Centering the dignity and autonomy of research participants as well as building upon and supporting existing social networks were identified as important facilitators for engaging Black transgender women in HIV cure-related research. Specific to Black transgender women, other concerns included the desire for gender-affirming research staff, community-building among transgender women, and safety issues associated with risk of transphobic violence when traveling to study visits. Participants stressed the importance of HIV cure-related researchers providing accessible and complete information and expressing genuine care and concern for transgender communities.

Reasons People Living with HIV Might Prefer Oral Daily Antiretroviral Therapy, Long-Acting Formulations, or Future HIV Remission Options

A growing body of research is beginning to elucidate reasons people living with HIV (PLWHIV) might prefer oral daily antiretroviral treatment (ART) compared with emerging long-acting ART (LA-ART) or HIV remission strategies under investigation. Our objective is to provide qualitative insights into the reasons why PLWHIV might prefer one of these HIV control therapies over others. From May to August 2018, we implemented a semistructured cross-sectional survey of PLWHIV in the United States to better understand patient preferences around various HIV treatment and remission options. Using free text, respondents were asked to explain why they preferred one HIV control option over the other two. We analyzed responses to the open-ended survey questions on reasons for preferring oral daily ART versus LA-ART versus HIV remission strategies using conventional content analysis. The results showed that PLWHIV preferred oral daily ART because of its familiarity and known safety and efficacy profile, whereas those who preferred LA-ART would value the convenience it offers. Finally, HIV remission strategies would be preferred to avoid taking ART altogether. The qualitative results provide insights into reasons why PLWHIV in the United States might prefer oral daily ART versus novel therapies. More importantly, they provide information to better align HIV virological control strategies with end-user perspectives. To make informed choices around evolving HIV therapeutics, PLWHIV and HIV care providers would benefit from decision tools to better assess options and trade-offs. More research is needed on how best to effectively support PLWHIV and HIV care providers in shared decision-making.

"My Death Will Not [Be] in Vain": Testimonials from Last Gift Rapid Research Autopsy Study Participants Living with HIV at the End of Life

End-of-life (EOL) HIV cure-related research provides a novel approach to studying HIV reservoirs. The Last Gift is a rapid autopsy research study at the University of California San Diego that enrolls terminally ill people living with HIV (PLWHIV) with a desire to contribute to HIV cure-related research. We conducted in-depth baseline and follow-up interviews with Last Gift study participants. We analyzed interview data applying conventional content analysis. Since summer 2017, 13 participants have been enrolled (n = 11 males and 2 females; aged 45-89 years) and 8 participants interviewed. Terminal illnesses included cancers, heart diseases, and neurodegenerative illnesses. Our analysis revealed five key themes: (1) The Last Gift study has tremendous meaning for participants at the end of their life. (2) HIV-specific altruism was a primary motivator to join the Last Gift study, nested within the context of community, scientific advancement, and moral obligation. (3) Participants did not expect physical benefits yet they perceived emotional/psychological, financial, and societal/scientific benefits. (4) There were minimal participant-perceived risks and concerns. (5) Last Gift participants expressed immense gratitude toward study staff. The Last Gift study provides a framework for ethical HIV cure-related research at EOL and highlighted participants' perspectives, motivations, and experiences. Knowing how PLWHIV understand and experience such studies will remain critical to designing ethical, fully informed HIV cure research protocols that are acceptable to PLWHIV.

Factors associated with attitudes towards HIV cure research among transgender women and travestis: a cross-sectional survey in São Paulo, Brazil

OBJECTIVE

Characterising the perceptions of groups most affected by HIV is fundamental in establishing guidelines for biomedical advancement. Although Brazil has successfully fought HIV/AIDS through several measures, transgender women still have a likelihood of HIV infection 55 times higher than the general population. This study aimed to better understand the perception and awareness of HIV cure research among the trans-identifying population in São Paulo, Brazil, and to determine factors that motivate or discourage participation in HIV cure studies.

SETTING

This cross-sectional study analysed data collected from a questionnaire administered to 118 transgender women and travestis at 5 sites within the city of São Paulo. It uses quantitative methodology to describe the perspectives of transgender and travesti people in relation to HIV cure research and the context in which such perspectives are produced.

RESULTS

Of 118 participants, most participants (73%) had some knowledge of HIV cure research and were most willing to participate in online surveys (52%), interviews (52%), focus groups (52%) and studies involving blood draws (57%). Those with a higher education or employment status were more likely to agree that someone had been cured of HIV, people living with HIV are discriminated against, and more information about HIV cure research is needed before the community embraces it. Only 55% of participants completely trusted their physician. The biggest motivational factors included gaining additional knowledge about HIV infection (77%) and the potential for a longer, healthier life for all (73%).

CONCLUSIONS

As a primary analysis of HIV cure attitudes among the transgender and travesti population as well as the social context in which they are formed, this study identifies opportunities to strengthen the dialogue and develop more educational collaborations between scientific investigators, community educators and the trans-identifying population to ensure that HIV cure research is inclusive of diverse perspectives.

Acceptability, motivation and the prospect of cure for people living with HIV and their healthcare providers in HIV cure-focused treatment interruption studies

BACKGROUND

Analytical treatment interruptions (ATI) are commonly used clinical endpoints to assess interventions aimed at curing HIV or achieving antiretroviral therapy (ART)-free HIV remission. Understanding the acceptability of ATI amongst people living with HIV (PLHIV) and their HIV healthcare providers (HHP) is limited.

METHODS

Two online surveys for PLHIV and HHP assessed awareness and acceptability of ATI, and understanding of the prospect for HIV cure in the future. Responses were collected from July 2017-January 2018. A descriptive analysis was performed and similar questions across the two surveys were compared using χ squared test.

RESULTS

442 PLHIV and 144 HHP completed the survey. 105/400 (26%) PLHIV had ever interrupted ART, 8% of which were in a clinical trial. Altruistic motivations were drivers of participation of PLHIV in cure related research. 81/135 (60%) HHP would support their patients wishing to enrol in an HIV cure-focused trial, but fewer would promote and allow such participation (25% and 31% respectively). Compared to HHP, PLHIV were more likely to believe that an HIV cure would be achievable within 10 years (55% vs. 19%, p < 0.001), had less awareness of ATI (46% vs. 62%, p < 0.001) and were less likely to have had experience of either participation or enrolment in an ATI study (5% vs. 18%, p < 0.001) CONCLUSION: PLHIV were more optimistic about the potential for HIV cure. HHP had more direct experience with HIV cure-focused studies. Educational strategies are required for both groups to increase understanding around ATIs in HIV cure research but should be tailored specifically to each group.

Re-examining the HIV 'functional cure' oxymoron: Time for precise terminology?

For over a decade, the binary concepts of 'sterilizing' versus 'functional' cure have provided an organizing framework for the field of HIV cure-related research. In this article, we examine how the expression 'functional cure' is employed within the field, published literature, and community understanding of HIV cure research. In our synthesis of the different meanings attributed to 'functional cure' within contemporary biomedical discourse, we argue that employing the 'functional cure' terminology poses a series of problems. The expression itself is contradictory and inconsistently used across a wide array of HIV cure research initiatives. Further, the meaning and acceptability of 'functional cure' within communities of people living with and affected by HIV is highly variable. After drawing lessons from other fields, such as cancer and infectious hepatitis cure research, we summarize our considerations and propose alternative language that may more aptly describe the scientific objectives in question. We call for closer attention to language used to describe HIV cure-related research, and for continued, significant, and strategic engagement to ensure acceptable and more precise terminology.

Altruism: Scoping review of the literature and future directions for HIV cure-related research

INTRODUCTION

The question of what motivates people to participate in research is particularly salient in the HIV field. While participation in HIV research was driven by survival in the 1980's and early 1990's, access to novel therapies became the primary motivator with the advent of combination antiretroviral therapy (cART) in the late 1990s. In the HIV cure-related research context, the concept of altruism has remained insufficiently studied.

METHODS

We conducted a scoping review to better contextualize and understand how altruism is or could be operationalized in HIV cure-related research. We drew from the fields of altruism in general, clinical research, cancer, and HIV clinical research-including the HIV prevention, treatment, and cure-related research fields.

DISCUSSION

Altruism as a key motivating factor for participation in clinical research has often been intertwined with the desire for personal benefit. The cancer field informs us that reasons for participation usually are multi-faceted and complex. The HIV prevention field offers ways to organize altruism-either by the types of benefits achieved (e.g., societal versus personal), or the origin of the values that motivate research participation. The HIV treatment literature reveals the critical role of clinical interactions in fostering altruism. There remains a dearth of in-depth knowledge regarding reasons surrounding research participation and the types of altruism displayed in HIV cure-related clinical research.

CONCLUSION

Lessons learned from various research fields can guide questions which will inform the assessment of altruism in future HIV cure-related research.

Hypothetical questionnaires may overestimate willingness to participate in HIV cure research: Comparison of a cross-sectional survey to actual willingness to participate in an HIV cure study in the Netherlands

Objective

Little is known about willingness among people living with HIV (PLHIV) to participate in HIV cure research in the Netherlands. We compared results of a cross-sectional questionnaire assessing hypothetical willingness to actual willingness among PLHIV to take part in a clinical HIV cure trial.

Methods

Between March and June 2018, PLHIV visiting the outpatient clinic of a university hospital in the Netherlands were asked to complete a questionnaire about HIV cure research. Results were compared to the number of PLHIV willing to take part in an actual HIV cure study at the same center during an overlapping time period.

Results

In total, 165 participants, predominantly male (80%) from Western European countries (61%) completed the questionnaire. The majority would participate in cure research (n ​= ​111, 67%). Separately, actual willingness among PLHIV to participate in an HIV cure study was addressed in 312 cases. Apart from gender (96% male), baseline characteristics were comparable. Less than half expressed actual willingness to participate in the study (n ​= ​135, 43%).

Conclusions

Hypothetical willingness to participate in cure-related research was high among PLHIV who completed the questionnaire. Actual willingness among eligible PLHIV to take part in an HIV cure study was much lower. Our findings show that questionnaires may overestimate willingness to participate in HIV cure trials and indicate that reasons for refusal in actual research should be further explored.

Perceptions of HIV Virologic Control Strategies Among Younger and Older Age Groups of People Living with HIV in the United States: A Cross-Sectional Survey

Two HIV virologic control advances are in various stages of development, including long-acting antiretroviral therapy (ART) formulations and strategies aimed at sustained ART-free HIV control. Perceptions of risks and benefits toward HIV virologic control strategies may be different based on an individual's age due to differing experiences of the impacts of the domestic HIV epidemic, altruistic attitudes toward research participation, and general levels of engagement in health care. We examined preferences of HIV virologic control strategies by age groups. In 2018, we conducted a nationwide, online cross-sectional survey to examine differences in HIV virologic control strategies among a sample of people living with HIV who were <50 and ≥50 years of age. From a total of 281 participants, 3 findings were noteworthy: (1) Participants <50 years of age were more likely to be demotivated by perceived social risks (e.g., stigma, discrimination, HIV disclosure, and fear of transmitting HIV during a treatment interruption), compared with those ≥50 years; (2) participants ≥50 years of age were more motivated by altruistic notions compared with those <50 years; and (3) we noted greater desirability of longer long-acting ART and new HIV cure-related strategies among participants <50 years versus those ≥50 years. Our analysis provides a deeper understanding of differences in perceptions among various age groups regarding desirable future ART characteristics, and motivations and barriers to participating in HIV cure-related strategies. Our findings can help inform community engagement and education, and assist researchers in tailoring study design and recruitment efforts to major age groups.

Willingness to risk death endpoint in HIV cure-related research with otherwise healthy volunteers is misleading

This viewpoint article critiques two recent articles examining 'willingness to risk death' to advance HIV cure-related research. The 'willingness to risk death' endpoint sends the wrong signal to the HIV cure-related research community about ongoing research in otherwise healthy volunteers living with HIV. Socio-behavioural scientists have examined the acceptability of a 99% risk of death scenario, which is unrealistic and would not be acceptable by current regulatory and ethical standards. We believe that the field needs robust and relevant socio-behavioural research reflecting ongoing biomedical HIV cure-related trials. These studies will need to withstand regulatory and ethical scrutiny if cure or remission regimens are to proceed to the licensing stage. The HIV cure-related research community must continue to protect the public trust in the HIV cure-related research field and sustain societal value generated by such research. We call for the utmost prudence in designing biomedical HIV cure trials as well as in setting up socio-behavioural research experiments related to these complex trials.

The Dose Response: Perceptions of People Living with HIV in the United States on Alternatives to Oral Daily Antiretroviral Therapy

There are two concurrent and novel major research pathways toward strategies for HIV control: (1) long-acting antiretroviral therapy (ART) formulations and (2) research aimed at conferring sustained ART-free HIV remission, considered a step toward an HIV cure. The importance of perspectives from people living with HIV on the development of new modalities is high, but data are lacking. We administered an online survey in which respondents selected their likelihood of participation or nonparticipation in HIV cure/remission research based on potential risks and perceived benefits of these new modalities. We also tested the correlation between perceptions of potential risks and benefits with preferences of virologic control strategies and/or responses to scenario choices, while controlling for respondent characteristics. Of the 282 eligible respondents, 42% would be willing to switch from oral daily ART to long-acting ART injectables or implantables taken at 6-month intervals, and 24% to a hypothetical ART-free remission strategy. We found statistically significant gender differences in perceptions of risk and preferences of HIV control strategies, and possible psychosocial factors that could mediate willingness to switch to novel HIV treatment or remission options. Our study yielded data on possible desirable product characteristics for future HIV treatment and remission options. Findings also revealed differences in motivations and preferences across gender and other sociodemographic characteristics that may be actionable as part of research recruitment efforts. The diversity of participant perspectives reveals the need to provide a variety of therapeutic options to people living with HIV and to acknowledge their diverse experiential expertise when developing novel HIV therapies.

The significance and expectations of HIV cure research among people living with HIV in Australia

Most people living with HIV (PLHIV) with reliable access to antiretroviral treatment (ART) have a life expectancy similar to uninfected populations. Despite this, HIV can negatively affect their social and psychological wellbeing. This study aimed to enhance understanding of the expectations PLHIV hold for HIV cure research and the implications this has for HIV cure research trials. We interviewed 20 Australian PLHIV about their expectations for HIV cure research outcomes and the impact a potential cure for HIV may have on their everyday lives. Data were analysed thematically, using both inductive and deductive approaches. The significance of a cure for HIV was expressed by participants as something that would offer relief from their sense of vigilance or uncertainty about their health into the future. A cure was also defined in social terms, as alleviation from worry about potential for onward HIV transmission, concerns for friends and family, and the negative impact of HIV-related stigma. Participants did not consider sustained medication-free viral suppression (or remission) as a cure for HIV because this did not offer certainty in remaining virus free in a way that would alleviate these fears and concerns. A cure was seen as complete elimination of HIV from the body. There is an ethical need to consider the expectations of PLHIV in design of, and recruitment for, HIV cure-related research. The language used to describe HIV cure research should differentiate the long-term aspiration of achieving complete elimination of HIV from the body and possible shorter-term therapeutic advances, such as achieving medication free viral suppression.

Crowdsourcing contests to facilitate community engagement in HIV cure research: a qualitative evaluation of facilitators and barriers of participation

BACKGROUND

As HIV cure research advances, there is an increasing need for community engagement in health research, especially in low- and middle-income countries with ongoing clinical trials. Crowdsourcing contests provide an innovative bottom-up way to solicit community feedback on clinical trials in order to enhance community engagement. The objective of this study was to identify facilitators and barriers to participating in crowdsourcing contests about HIV cure research in a city with ongoing HIV cure clinical trials.

METHODS

We conducted in-depth interviews to evaluate facilitators and barriers to participating in crowdsourcing contests in Guangzhou, China. Contests included the following activities: organizing a call for entries, promoting the call, evaluating entries, celebrating exceptional entries, and sharing entries. We interviewed 31 individuals, including nine HIV cure clinical trial participants, 17 contest participants, and five contest organizers. Our sample included men who have sex with men (20), people living with HIV (14), and people who inject drugs (5). We audio-recorded, transcribed, and thematically analyzed the data using inductive and deductive coding techniques.

RESULTS

Facilitators of crowdsourcing contest participation included responsiveness to lived experiences, strong community interest in HIV research, and community trust in medical professionals and related groups. Contests had more participants if they responded to the lived experiences, challenges, and opportunities of living with HIV in China. Strong community interest in HIV research helped to drive the formulation and execution of HIV cure contests, building support and momentum for these activities. Finally, participant trust in medical professionals and related groups (community-based organizations and contest organizers) further strengthened the ties between community members and researchers. Barriers to participating in crowdsourcing contests included persistent HIV stigma and myths about HIV. Stigma associated with discussing HIV made promotion difficult in certain contexts (e.g., city squares and schools). Myths and misperceptions about HIV science confused participants.

CONCLUSIONS

Our data identified facilitators and barriers of participation in HIV cure crowdsourcing contests in China. Our findings could complement existing HIV community engagement strategies and help to design HIV contests for community engagement in other settings, particularly in low- and middle-income countries.

Applying the Behavioural and Social Sciences Research (BSSR) Functional Framework to HIV Cure Research

INTRODUCTION

The search for an HIV cure involves important behavioural and social processes that complement the domains of biomedicine. However, the field has yet to tap into the full potential of behavioural and social sciences research (BSSR). In this article, we apply Gaist and Stirratt's BSSR Functional Framework to the field of HIV cure research.

DISCUSSION

The BSSR Functional Framework describes four key research domains: (1) basic BSSR (understanding basic behavioural and social factors), (2) elemental BSSR (advancing behavioural and social interventions), (3) supportive BSSR (strengthening biomedically focused clinical trials), and (4) integrative BSSR (building multi-disciplinary combination approaches for real-world implementation). In revisiting and applying the BSSR Functional Framework, we clarify the importance of BSSR in HIV cure research by drawing attention to such things as: how language and communication affect the meaning of "cure" to people living with HIV (PLHIV) and broader communities; how cure affects the identity and social position of PLHIV; counselling and support interventions to address the psychosocial needs and concerns of study participants related to analytical treatment interruptions (ATIs); risk reduction in the course of ATI study participation; motivation, acceptability, and decision-making processes of potential study participants related to different cure strategies; HIV care providers' perceptions and attitudes about their patients' participation in cure research; potential social harms or adverse social events associated with cure research participation; and the scalability of a proven cure strategy in the context of further advances in HIV prevention and treatment. We also discuss the BSSR Functional Framework in the context of ATIs, which involve processes at the confluence of the BSSR domains.

CONCLUSIONS

To move HIV cure regimens through the translational research pathway, attention will need to be paid to both biomedical and socio-behavioural elements. BSSR can contribute an improved understanding of the human and social dimensions related to HIV cure research and the eventual application of HIV cure regimens. The BSSR Functional Framework provides a way to identify advances, gaps and opportunities to craft an integrated, multi-disciplinary approach at all stages of cure research to ensure the real-world applicability of any strategy that shows promise.

What is the effect of self-identified HIV activism in willingness to participate in HIV cure-related clinical trials? Results from the ANRS-APSEC study

OBJECTIVES

Enrolling people living with HIV with undetectable viral load into HIV cure-related clinical trials (HCRCT) is challenging. Few data are currently available about the individual factors that influence willingness to participate in HCRCT (WPHCRCT). We hypothesised that WPHCRCT would be more frequent among people living with HIV considering themselves HIV activists. The objective of this study was to investigate the individual characteristics associated with both WPHCRCT and self-identification as an HIV activist.

METHODS

The study enrolled 195 long-term ART-treated and virologically suppressed people living with HIV, followed-up in 19 French HIV services, 2016-2017. A Bayesian model averaging approach was used to assess correlates of both outcomes i.e. WPHCRCT and self-identified HIV activism.

RESULTS

WPHCRCT was reported by 43% of participants and was positively associated with self-identification as an HIV activist (adjusted odds ratio [aOR] 2.90 95% confidence interval [CI] 2.17-3.63], P<0.05) and self-confidence as an HIV positive person (aOR 1.17, 95% CI 0.99-1.35, P<0.1). Self-identified HIV activists (56% of participants) were more likely to have a higher 'relationship with others' score using the post-traumatic growth inventory (aOR 1.10, 95% CI 0.99-1.20, P<0.1), to obtain information about HIV from a greater number of sources (aOR 1.35 [95% CI 1.00-1.68], P<0.1), and to feel greatly affected by mandatory daily treatment (aOR 2.15, 95% CI 1.27-3.03, P<0.1). All associations had relative importance weight>0.75, indicating strong evidence.

CONCLUSIONS

WPHCRCT is strongly related to HIV activism, and also to positive psychosocial characteristics as a person living with HIV, especially regarding relationships with others. The desire to contribute to the fight against HIV for the sake of the HIV community and society should be taken into account to improve participation in upcoming HCRCT.

Acceptability of Cell and Gene Therapy for Curing HIV Infection Among People Living with HIV in the Northwestern United States: A Qualitative Study

Multiple strategies to cure HIV infection are under investigation, including cell and gene therapy (C>) approaches. Research, and ultimately treatment, with these novel strategies will require patients' willingness to participate. To elicit the perspectives of people living with HIV specific to these novel approaches, we conducted 4 focus group discussions with a diverse group of 19 English-speaking men and women living with HIV in care at a large academic HIV clinic in the northwestern United States. Thematic analysis indicated participants expressed initial fear about C> research. They articulated specific concerns about risks, including analytical treatment interruptions, and thought only a person in desperate straits would participate. They voiced significant mistrust of research in general and believed there was already a cure from HIV that was being withheld from the poor. Overall, they were satisfied with their health and quality of life on antiretroviral therapy. These findings suggest the importance of community engagement and educational efforts about C> for HIV cure to ensure optimal collaborative partnerships.

Going off antiretroviral treatment in a closely monitored HIV "cure" trial: longitudinal assessments of acutely diagnosed trial participants and decliners

INTRODUCTION

The South East Asia Research Collaboration in HIV (SEARCH) RV411 clinical trial in Thailand was a systematic investigation of analytic treatment interruption (ATI) in individuals diagnosed and treated since Fiebig stage I acute HIV infection. Here, we explore decision-making processes and perceptions of trial participation in a phase I trial that raised important ethical considerations, to identify potential areas of improvement in this relatively new field of HIV research. Similar considerations apply to other HIV phase I trials, especially those involving ATI, making this trial a model to identify challenges and opportunities in promoting informed choice.

METHODS

Using longitudinal semi-structured interviews and a validated questionnaire, we examined how decisions to join or decline the trial were made, whether there was evidence of decisional conflict, and reactions to the trial outcomes. We also explored contrasting views and experiences in this small trial cohort. We report analyses of data from these questionnaires and interviews, conducted from February through December of 2016 with the 14 SEARCH cohort participants who either joined (n = 8) or declined (n = 6) participation in RV411.

RESULTS

The eight participants and six decliners had low overall decisional conflict, which remained low over time. Decision making was more difficult for decliners than participants, at least initially. While all interviewees described being satisfied with their decisions, our study identified important negative consequences for a few individuals, including seroconversion, negative experiences with optional procedures and disappointment due to rapid viral rebound.

CONCLUSIONS

Although our results reflect the experiences of a small group invited to join this trial, our overall finding of low decisional conflict even while some individuals reported negative experiences provides lessons for clinical trial investigators. We developed points-to-consider in helping participants make informed choices, to support participants during the trial and to support decliners in their decisions.
