AVAC welcomes the groundbreaking results of the PURPOSE 2 HIV prevention study of twice-yearly injectable lenacapavir for PrEP among 3,200 cisgender men, transgender men, transgender women, and nonbinary individuals who have sex with partners assigned male at birth. Among more than 2,000 people in the trial who received lenacapavir, there were only two HIV infections.

“This is the second impressive result for this new HIV prevention option, opening up more possibilities for choice for even more people to find an option that is right for them,” said Mitchell Warren, AVAC’s executive director. “Beyond expanded choice, a twice-yearly injection has the potential to transform the way we deliver HIV prevention to people who need and want it most – from an easier to follow regimen for individuals to a decreased burden on healthcare systems that are stretched to the limit. But these data only matter if the field moves with speed, scale and equity.”

“Having results from a trial population that includes trans men and women, nonbinary people and gay men is an important milestone for community inclusion in HIV prevention studies,” said Kenyon Farrow, AVAC communications director and PrEP user since 2015. “I am excited that people who want to use PrEP or who fear stigma or discrimination, may soon have the possibility of another option that could be much easier to use and provide more discretion. It is imperative that we accelerate planning for rollout of lenacapavir. We know that even with the most ambitious timeline, it will take time for lenacapavir to be rolled out to all who need and want to use it.”

The study evaluated the safety and efficacy of twice-yearly injectable lenacapavir for PrEP compared to once-daily oral emtricitabine/tenofovir and background HIV incidence. All trial participants will now be offered lenacapavir. Additional studies in critical populations, including PURPOSE 3 among cisgender women in the US and PURPOSE 4 among people who inject drugs, are also underway. It will be imperative to understand how today’s results influence these trials. A schematic of the suite of studies is here.
