PxWire Volume 15, Issue 3
This issue of PxWire looks at the scale of shuttered prevention programs for key populations, the potential market for injectable LEN, and the devastating cuts to research for an HIV vaccine.
Prevention Option:
Impact of US Funding Cuts on Services for Key Populations
Percentage of key population-serving implementing partners that have reported full or partial termination of the provision of KP services due to US funding cuts (as of April 2025).
Prevention Option:
Potential Demand for LEN for PrEP
The top 16 PrEP markets, based on 2024 oral PrEP initiations and the possible 2026 injectable market, assuming 60% of new PrEP users choose an injectable, as seen in implementation studies.
Prevention Option:
Impact of Cuts to the Consortia for HIV/AIDS Vaccine Development (CHAVD)
In May 2025, NIH’s National Institute of Allergy and Infectious Diseases (NIAID) announced that funding for the Consortia for HIV/AIDS Vaccine Development (CHAVD) would end after the current grant cycle in June 2026. With only one more year of funding before the grants end, current plans for research, clinical trials and progress toward a vaccine are all at risk.

This graphic shows currently available options for HIV prevention, newly approved and recommended treatment, and those in development.

An Overview of Lenacapavir for PrEP Trials
The PURPOSE trials evaluate the safety and efficacy of injectable lenacapavir (LEN), an investigational antiretroviral (ARV) drug being studied as a potential PrEP product. This graphic shows the latest status of all five trials including the groundbreaking results of PURPOSE 1 and PURPOSE 2.
Prevention Option:
Moving a Product to the Real World
To reach the UNAIDS target of 10 million PrEP users by 2025, initiations of oral PrEP alone will not be enough—and this graphic shows that the field is beginning to apply past lessons to accelerate introduction of injectable cabotegravir.
Prevention Option:
LEN Generics — Can we go faster?
The timeline for generic LEN for PrEP to come to market is expected to be significantly shorter than for CAB for PrEP. Bioequivalence (BE) testing for LEN, which demonstrates a generic product works in the body in the same way as the originator product, is likely to be six months, vs. the 18 months for CAB for PrEP, because of differences in the drug formulation.
Prevention Option:
Where We Are Now with LEN for PrEP
The chaos in foreign assistance programs (including discontinuation of major PrEP programs), cuts in staffing and new demands on donor commitments will make decisions on the procurement of LEN for PrEP more complex and uncertain.
Prevention Option:
Lenacapavir Regulatory Approval
Regulatory approvals, pending decisions, and appeals as of June 2025, including US Food and Drug Administration approval. For product approvals, volumes, implementation, and price comparisons of long-acting PrEP, visit our dashboard...
