FOSTER CITY, Calif. - Gilead Sciences, Inc. (NASDAQ:GILD) has reported that its Phase 3 trial of an injectable HIV prevention drug, lenacapavir, achieved a 100% efficacy rate in an interim analysis. The PURPOSE 1 trial, which compared the drug to daily oral Truvada, revealed no new HIV infections among participants receiving lenacapavir.
The trial involved over 5,300 cisgender women and adolescent girls in South Africa and Uganda, who were administered the drug twice yearly. The independent Data Monitoring Committee has recommended the termination of the blinded phase of the trial due to these positive results, allowing all participants access to lenacapavir.
Dr. Merdad Parsey, Chief Medical Officer at Gilead Sciences, expressed optimism about the potential of lenacapavir as a valuable tool in preventing HIV infections. The PURPOSE program, which includes this trial, aims to innovate in trial design and community engagement, particularly focusing on those disproportionately affected by HIV.
While lenacapavir showed superior efficacy to Truvada and the background HIV incidence, the Descovy group did not demonstrate statistical superiority. Adherence to daily oral pills has been a challenge in previous trials, and further analysis is ongoing.
Linda-Gail Bekker, Director of the Desmond Tutu HIV Center, highlighted the benefits of lenacapavir, such as reduced stigma and improved adherence due to its infrequent dosing schedule.
However, it's important to note that lenacapavir, as well as Descovy for HIV prevention in cisgender women, remains investigational and has yet to be approved for safety or efficacy globally.
Gilead anticipates additional results from the PURPOSE 2 trial, which includes a broader demographic, by late 2024 or early 2025. The company is also planning to discuss access strategies for lenacapavir in high-incidence, resource-limited countries.
