Gilead Sciences Conducts Phase II Trials for Long-Acting HIV Prevention Drug

Gilead Sciences is advancing two Phase II studies, PURPOSE 3 (HPTN-102) and PURPOSE 4 (HPTN-103), to evaluate the efficacy of lenacapavir, a long-acting HIV prevention drug, administered every six months. These trials specifically target cisgender women, particularly those of color who are at higher risk, and individuals who inject drugs in the US. The first participants in PURPOSE 3 were enrolled at the University of California, San Diego. The studies aim to assess the safety, acceptability, and pharmacokinetics of lenacapavir as a pre-exposure prophylaxis (PrEP) option, potentially offering a more accessible prevention method for those who struggle with existing PrEP modalities.

Key Takeaways

  • Gilead Sciences is conducting Phase II studies to assess lenacapavir for HIV prevention in cisgender women and people who inject drugs in the US.
  • The PURPOSE 3/HPTN-102 study focuses on enrolling cisgender women, especially those disproportionately affected by HIV.
  • PURPOSE 4/HPTN-103 targets individuals who inject drugs, aiming to evaluate the safety and efficacy of lenacapavir.
  • These trials evaluate the safety, acceptability, and pharmacokinetics of twice-yearly lenacapavir injections as a pre-exposure prophylaxis (PrEP) option.
  • The first participants for PURPOSE 3/HPTN-102 were enrolled at the University of California, San Diego.


Gilead Sciences' Phase II trials for lenacapavir, targeting high-risk groups like cisgender women and drug injectors, could revolutionize HIV prevention. This long-acting, twice-yearly injection aims to overcome adherence challenges common with daily PrEP. Success could significantly reduce HIV incidence in these demographics, particularly among communities of color, and bolster Gilead's market position in HIV treatment. Conversely, setbacks could delay crucial advancements in accessible HIV prevention. Regulatory approval and healthcare policy will play pivotal roles in determining the drug's accessibility and impact on public health.

Did You Know?

  • Lenacapavir: A long-acting HIV prevention drug developed by Gilead Sciences. It is designed to be administered every six months, aiming to provide a more accessible and convenient pre-exposure prophylaxis (PrEP) option compared to daily oral medications currently in use.
  • Pre-exposure Prophylaxis (PrEP): A method of preventing HIV infection where individuals who are at high risk of contracting HIV take antiretroviral medication regularly to reduce their chances of infection. Lenacapavir, as a PrEP, offers a novel approach with its long-acting, injectable formulation.
  • Cisgender: A term used to describe individuals whose gender identity corresponds with their sex assigned at birth. In the context of the studies mentioned, the focus on cisgender women highlights the targeted approach to address specific demographics at higher risk of HIV infection.
