The promise of long-acting PrEP has been super-charged this year by studies showing the powerful efficacy of an antiretroviral known as lenacapavir (LEN).
This episode of PxPulse goes deep on LEN for PrEP. Recorded just days before Gilead’s announcement that PURPOSE 2 also found very high efficacy, Dr. Flavia Kiweewa, a principal investigator of PURPOSE 1, the first trial to announce efficacy, lays out the research findings and what they mean. And Chilufya Kasanda Hampongo of Zambia’s Treatment Advocacy and Literacy Campaign and Mitchell Warren of AVAC talk about how to change a long history of squandered opportunities to get rollout right.
The PURPOSE1 trials announced findings in June that a twice-yearly injection of LEN was 100% effective among cisgender women, with zero new cases of HIV. And the PURPOSE 2 trial among cisgender men, and trans and non-binary people, was shown to reduce the risk of HIV by 96%.
LEN now enters a select category, one of five ARV-based options for PrEP that all protect against HIV if you take them. But many of the people applauding the results from PURPOSE 1 and 2 will tell you that breakthrough science like this is, as hard as it is, is still the easy part. To break the back of the HIV epidemic demands overcoming an altogether different challenge—coordinating and accelerating every step in rolling out new products so that everyone who needs HIV prevention can get it.
Listen to this podcast to learn what must be done to finally deliver on the promise of highly effective HIV prevention, from pills to rings to injectable PrEP and beyond.
