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.

The lack of socio-behavioral research on stress and psychosocial experiences among research participants who undergo analytical treatment interruption (ATI) in HIV cure studies underscores a critical gap in cure science. Existing literature acknowledges mixed and potentially adverse mental health impacts of ATIs among trial participants, but empirical insights before, during, and after clinical studies are scarce. We used longitudinal in-depth interviews with 11 participants in HIV cure-related research to explore their experiences with stress, coping, and psychological well-being before, during, and after an ATI.

Background: A key research priority for developing an HIV cure strategy is to define the viral dynamics and biomarkers associated with sustained post-treatment control. The ability to predict the likelihood of sustained post-treatment control or non-control could minimize the time off antiretroviral therapy (ART) for those destined to not control and anticipate longer periods off ART for those destined to control.
Methods: Mathematical modeling and machine learning were used to characterize virologic predictors of long-term virologic control using viral kinetics data from several studies in which participants interrupted ART.

Purpose Of Review: While post-treatment control following interruption of standard-of-care antiretroviral therapy (ART) is well described, post-intervention control following immunotherapy in HIV cure-related clinical trials is less well understood. We provide an overview of recent studies that have identified post-intervention controllers and review the mechanisms that may drive this biologically important phenotype.
Recent Findings: Post-intervention controllers have been identified in recent immunotherapy trials testing broadly neutralizing antibodies, immune modulators, modified T cells, checkpoint inhibitors, and gene therapy administered individually or in combination.

It is well established that humoral immunity targeting hepatitis B virus surface antigen (HBsAg) plays a critical role in viral clearance and clinical cure. However, the functional changes in HBsAg-specific B cells before and after achieving functional cure remain poorly understood. In this study, we characterized circulating HBsAg-specific B cells and identified functional shifts and B-cell epitopes directly associated with HBsAg loss.

Analytical treatment interruptions (ATIs) are widely used to evaluate HIV cure-related research interventions. However, sex partners of cure-related trial participants might be at risk of acquiring HIV during ATIs. Addressing this risk is key to ensuring the continued success of trials involving ATIs and offer greater acceptability across multiple trials sites.
