The Lens on LEN
The Basics on Injectable Lenacapavir as PrEP
In late June 2024, Gilead Sciences announced an early review of the data of the PURPOSE 1 trial by an independent monitoring board, which found that injectable lenacapavir (LEN) provided as prevention was safe and highly effective against HIV. The product is being tested among 5,300 HIV-negative cisgender women ages 16-25 in Uganda and South Africa. No infections were seen among those receiving LEN. This advocates’ primer provides further background on the product and trials, raises key questions, and explores next steps.
