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.

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...

Advocates’ Guide to Lenacapavir
This wide-ranging slide deck gives a complete overview of lenacapavir — showing the overall prevention product pipeline, describes lenacapavir, compares it to other options, discusses the trials testing the product, next steps, and links to advocacy resources.
Prevention Option:
Getting PrEP Rollout Right This Time
Getting PrEP Rollout Right This Time: Lessons from the Field examines key insights from the rollout of oral PrEP and early introduction of injectable CAB and the dapivirine vaginal ring to inform a faster, smarter and more equitable introduction of future HIV prevention tools, including long-acting injectable PrEP, such as lenacapavir.
Prevention Option:
The Scientific Journey of Lenacapavir — and the Urgency to Defend HIV Prevention Science
On June 11, AVAC hosted a conversation, The Scientific Journey of Lenacapavir: From basic science to clinical development to impact, to explore how US support from NIH for basic science and South Africa’s clinical research infrastructure made possible the development of lenacapavir for PrEP (LEN), a discovery in HIV prevention that went on to be named Science magazine’s 2024 Breakthrough of the Year.

HIV Prevention R&D at Risk
AVAC’s analysis of the impact of US Government funding cuts, terminated projects, and other policy changes on the HIV prevention research and development (R&D) pipeline, and on HIV research broadly.
