New long-acting technologies are changing the HIV prevention landscape. In recent years, innovation in pre-exposure prophylaxis (PrEP) has accelerated. Long acting injectable cabotegravir and the dapivirine vaginal ring as innovative formulations of PrEP have already joined oral PrEP containing tenofovir as WHO-recommended effective and acceptable options for HIV prevention, and there are additional antiretroviral-based options on the immediate horizon. These options complement other effective, non-antiretroviral-based HIV prevention products including condoms and lubricants, and harm reduction strategies.
This year clinical trial results for PURPOSE 1 and 2 showed the high prevention effectiveness of the 6-monthly long-acting injectable drug, lenacapavir for cisgender adolescent girls and women, cisgender men and transgender women. Among the cisgender adolescent girls and women participating in the trial, no HIV acquisitions were recorded during 12 months of follow-up among the women who received injectable lenacapavir. The Global HIV Prevention Coalition (GPC), UNAIDS and other partners called on Gilead Sciences to accelerate their efforts in ensuring that it is made available, accessible and cost effective especially to low- and middle-income countries. This twice-yearly injection is a promising option and offers increased choice, discretion and convenience for people who may benefit from HIV prevention.
In October 2024, at the Research for Prevention (R4P) conference in Peru, the Population Council announced phase 1 trial results from IPM 054, showing that the three-month dapivirine ring is as safe as the currently available one-month ring with similar levels of drug release. The 3-month ring like the 1-month ring is a woman-controlled option but would be more cost effective (an estimated 60% reduction in cost per user) and potentially an even more convenient HIV prevention option for women and adolescent girls.
“We need to follow the science, and the science has shown us that by making a range of effective HIV prevention options available and accessible, we can stop HIV transmission and drop new infections by addressing biomedical, behavioral and structural drivers simultaneously. Ending AIDS remains a political and financial choice”, says Angeli Achrekar, UNAIDS Deputy Executive Director Programmes.
This complements a partnership announcement by the Global Fund and the Children’s Investment Fund Foundation (CIFF) of an USD 2 million initiative for 2024-2025 to purchase an estimated 150 000 dapivirine vaginal rings for use as PrEP in the Global Fund grant implementing countries. This would increase accessibility to one of the most discreet HIV prevention options for women and adolescent girls.
The World Health Organization (WHO) PrEP Implementation Tool Provider Module for Oral and Long Acting PrEP, launched in July 2024, integrates clinical service delivery guidance for the three WHO recommended PrEP products (oral PrEP, the dapivirine vaginal ring and long-acting injectable cabotegravir) by a range of different providers in clinical or community settings and emphasizes the importance of access and choice.
These strategic advancements align to the HIV Prevention Choice Manifesto For Women and Girls in Africa that calls for prevention options to be made choices and urges that research and development of new HIV prevention options actual choices, thereby empowering women and girls to take control of their health and bodies. It also emphasizes the importance of ongoing research and development of innovative HIV prevention methods.
“Adolescent girls and women are gaining access to an increasing range of safe and effective options. Scale-up of HIV prevention will depend on supporting access to choice, strong country leadership and an enabling environment. An HIV free future for girls is possible, but only if the global community comes together with ambitious plans to make this range of PrEP options available with speed, scale and equity,” says Mitchell Warren, Executive Director, AVAC and GPC, Co-chair.
The GPC co-convened, by UNAIDS and UNFPA, will continue to work with its partners to accelerate HIV prevention to achieve the global target of less than 370 000 new HIV infections annually by 2025.
About the GPC
In 2017, a global coalition of United Nations Member States, donors, civil society organizations, and implementers was established to support global efforts to accelerate HIV prevention. Membership includes 38 of the highest HIV-burden countries, UNAIDS Cosponsors, donors, civil society, and private sector organizations. The overarching goal of the Global HIV Prevention Coalition is to strengthen and sustain a political commitment to primary prevention by setting a common agenda among key policymakers, funders, and program implementers.
