On July 24th, during the highly anticipated Co-Chairs' Choice session at the 25th International AIDS Conference in Munich, Germany, the PURPOSE 1 study was unveiled, highlighting a significant breakthrough in HIV prevention. The study demonstrated the exceptional efficacy of the long-acting injectable drug Lenacapavir in preventing HIV infection among women. The study was simultaneously published online in The New England Journal of Medicine. Conducted in South Africa and Uganda, this double-blind, randomized controlled trial compared different prevention strategies and found that biannual injections of Lenacapavir effectively blocked HIV infection, resulting in zero cases of infection. The efficacy of Lenacapavir far surpassed that of daily oral F/TAF and F/TDF. The study not only confirmed Lenacapavir's high effectiveness but also revealed its potential to improve patient adherence, offering a new solution to one of the major challenges in HIV prevention. With the widespread application of Lenacapavir, global HIV prevention strategies may be poised for significant change. Infectious Diseases Frontier invited Dr. Hui Wang from the Second Affiliated Hospital of Southern University of Science and Technology (Shenzhen Third People's Hospital) to provide an in-depth commentary and analysis of this study.
