A revolutionary HIV prevention drug, lenacapavir, shows promise in clinical trials with a 96% reduction in HIV risk.
At a Glance
- Lenacapavir is a long-acting injectable HIV prevention drug administered every six months
- Clinical trials show a 96% reduction in HIV risk among participants
- The drug offers an alternative to daily oral PrEP, potentially improving adherence
- Lenacapavir has been named the 2024 Breakthrough of the Year by Science magazine
- Efforts are underway to make the drug more accessible globally
Groundbreaking HIV Prevention Drug Enters Clinical Trials
The National Institutes of Health (NIH) has initiated two clinical trials to test lenacapavir, a long-acting HIV pre-exposure prophylaxis (PrEP) injection. These trials focus on cisgender women and people who inject drugs, groups historically underrepresented in HIV research. Lenacapavir, an antiretroviral drug administered every six months, is already FDA-approved for certain HIV treatments. The trials aim to assess the safety, acceptability, and pharmacokinetics of lenacapavir, with participants randomly assigned to receive either lenacapavir or an oral PrEP formulation.
The PURPOSE-2 trial has shown promising results for long-acting injectable lenacapavir (LEN) in HIV prevention. Participants experienced a remarkable 96% reduction in HIV risk, demonstrating LEN’s potential as a game-changing preventive measure. Furthermore, LEN proved to be 89% more effective than daily oral TDF/FTC in preventing HIV acquisition. Both LEN and daily oral TDF/FTC were well tolerated, with no significant safety concerns reported.

Advantages of Lenacapavir in HIV Prevention
Lenacapavir’s twice-yearly dosing offers significant advantages for individuals facing challenges with daily oral PrEP adherence. This innovative approach could potentially transform HIV prevention strategies, especially in regions like sub-Saharan Africa where HIV prevalence remains high. The drug’s effectiveness and convenience have led to its recognition as the 2024 Breakthrough of the Year by Science magazine.

Advocacy groups and researchers view lenacapavir as a potential game-changer in the fight against HIV. The drug has been approved for multi-drug resistant HIV treatment in the U.S. since 2022, but its use for prevention is still under regulatory review. This development represents a significant leap forward in HIV prevention efforts, offering hope for reducing the global burden of HIV/AIDS.

Challenges and Future Prospects
Despite its promising results, lenacapavir faces challenges in terms of cost and accessibility. The current treatment cost of lenacapavir is significantly higher than oral PrEP options, which could limit its widespread adoption. However, efforts are underway to make lenacapavir more accessible globally, with a potential market launch aimed for 2025.

The World Health Organization (WHO) is preparing to develop guidelines for lenacapavir’s use in HIV prevention and is collaborating with partners to ensure affordable and equitable access. This commitment from global health authorities underscores the drug’s potential to revolutionize HIV prevention strategies worldwide.
