Ensuring People Living with HIV Inform the Future of HIV Treatment in Low- and Middle-Income Countries: A Scoping Review and Recommendations for a Community-Led Research Agenda.

The HIV treatment landscape in low- and middle-income countries (LMICs) is rapidly evolving, exemplified by the expansion of differentiated service delivery (DSD) during the coronavirus disease (COVID-19) pandemic. Long-acting products represent a new frontier that will require a significant redesign of health systems. It is critical to understand service delivery and product preferences of people living with HIV (PLHIV) and ensure evidence generation is guided by community priorities. We conducted a scoping review to identify gaps among preference studies and inform future research. Peer-reviewed articles published from January 2014-May 2022 reporting acceptability or preference data from PLHIV or caregivers for one or more service delivery or product attribute were eligible. Service delivery studies were restricted to LMIC populations while product studies had no geographical restrictions. Based on gaps identified, we consulted advocates to develop community-led research agenda recommendations. Of 6,493 studies identified, 225 studies on service delivery attributes and 47 studies on product preferences were eligible. The most frequently studied delivery models were integration (n = 59) and technology-based interventions (n = 55). Among product literature, only 15 studies included LMIC populations. Consultation with advocates highlighted the need for research on long-acting products, including among pediatric, pregnant, and breastfeeding PLHIV, PLHIV on second-line regimens, and key populations. Consultation also emphasized the need to understand preferences on clinic visit frequency, side effects, and choice. While the preference literature has expanded, gaps remain around long-acting regimens and their delivery. To fill these gaps, the research agenda must be guided by the priorities of communities of PLHIV.

HIV Prevention in a Time of COVID-19: A Report from the HIVR4P // Virtual Conference 2021.

The HIV Research for Prevention (HIVR4P) conference catalyzes knowledge sharing on biomedical HIV prevention interventions such as HIV vaccines, antibody infusions, pre-exposure prophylaxis, and microbicides in totality-from the molecular details and delivery formulations to the behavioral, social, and structural underpinnings. HIVR4P // Virtual was held over the course of 2 weeks on January 27-28 and February 3-4, 2021 as the coronavirus disease 2019 (COVID-19) pandemic continued to inflict unprecedented harm globally. The HIVR4P community came together with 1,802 researchers, care providers, policymakers, implementers, and advocates from 92 countries whose expertise spanned the breadth of the HIV prevention pipeline from preclinical to implementation. The program included 113 oral and 266 poster presentations. This article presents a brief summary of the conference highlights. Complete abstracts, webcasts, and daily rapporteur summaries may be found on the conference website (https://www.hivr4p.org/).

Ending the evidence gap for pregnancy, HIV and co-infections: ethics guidance from the PHASES project.

INTRODUCTION: While pregnant people have been an important focus for HIV research, critical evidence gaps remain regarding prevention, co-infection, and safety and efficacy of new antiretroviral therapies in pregnancy. Such gaps can result in harm: without safety data, drugs used may carry unacceptable risks to the foetus or pregnant person; without pregnancy-specific dosing data, pregnant people face risks of both toxicity and undertreatment; and delays in gathering evidence can limit access to beneficial next-generation drugs. Despite recognition of the need, numerous barriers and ethical complexities have limited progress. We describe the process, ethical foundations, recommendations and applications of guidance for advancing responsible inclusion of pregnant people in HIV/co-infections research. DISCUSSION: The 26-member international and interdisciplinary Pregnancy and HIV/AIDS: Seeking Equitable Study (PHASES) Working Group was convened to develop ethics-centred guidance for advancing timely, responsible HIV/co-infections research with pregnant people. Deliberations over 3 years drew on extensive qualitative research, stakeholder engagement, expert consultation and a series of workshops. The guidance, initially issued in July 2020, highlights conceptual shifts needed in framing research with pregnant people, and articulates three ethical foundations to ground recommendations: equitable protection from drug-related risks, timely access to biomedical advances and equitable respect for pregnant people's health interests. The guidance advances 12 specific recommendations, actionable within the current regulatory environment, addressing multiple stakeholders across drug development and post-approval research, and organized around four themes: building capacity, supporting inclusion, achieving priority research and ensuring respect. The recommendations describe strategies towards ethically redressing the evidence gap for pregnant people around HIV and co-infections. The guidance has informed key efforts of leading organizations working to advance needed research, and identifies further opportunities for impact by a range of stakeholder groups. CONCLUSIONS: There are clear pathways towards ethical inclusion of pregnant people in the biomedical research agenda, and strong agreement across the HIV research community about the need for - and the promise of - advancing them. Those who fund, conduct, oversee and advocate for research can use the PHASES guidance to facilitate more, better and earlier evidence to optimize the health and wellbeing of pregnant people and their children.

Optimizing responses to drug safety signals in pregnancy: the example of dolutegravir and neural tube defects.

INTRODUCTION: The unexpected identification of a neural tube defect (NTD) safety signal with preconception dolutegravir (DTG) exposure in the Botswana Tsepamo birth outcomes study brought into sharp focus the need for reliable data on use of new antiretrovirals in pregnancy, improved pharmacovigilance systems to evaluate safety of new drugs being introduced into populations including women of reproductive potential, and balanced risk-benefit messaging when a safety signal is identified. DISCUSSION: The Tsepamo study NTD safety signal and accompanying regulatory responses led to uncertainty about the most appropriate approach to DTG use among women of reproductive potential, affecting global DTG roll-out plans, and limiting DTG use in adolescent girls and women. It also revealed a tension between a public health approach to antiretroviral treatment (ART) and individual choice, and highlighted difficulties interpreting and messaging an unexpected safety signal with uncertainty about risk. This difficulty was compounded by the lack of high-quality data on pregnancy outcomes from women receiving ART outside the Tsepamo surveillance sites and countries other than Botswana, resulting in a prolonged period of uncertainty while data on additional exposures are evaluated to refute or confirm the initial safety signal. We discuss principles for evaluating and introducing new drugs in the general population that would ensure collection of appropriate data to inform drug safety in adolescent girls and women of reproductive potential and minimize confusion about drug use in this population when a safety signal is identified. CONCLUSIONS: The response to a signal suggesting a possible safety risk for a drug used in pregnancy or among women who may become pregnant needs to be rapid and comprehensive. It requires the existence of appropriately designed surveillance systems with broad population coverage; data analyses that examine risk-benefit trade-offs in a variety of contexts; guidance to transform this risk-benefit balance into effective and agreed-upon policy; involvement of the affected community and other key stakeholders; and a communication plan for all levels of knowledge and complexity. Implementation of this proposed framework for responding to safety signals is needed to ensure that any drug used in pregnancy can be rapidly and appropriately evaluated should a serious safety alert arise.
