Gilead Sciences' Lenacapavir Prevents 100% of HIV Cases in Women and Girls in Africa
Gilead Sciences has announced a groundbreaking development in the fight against HIV. Its experimental twice-yearly HIV shot, lenacapavir, has successfully prevented 100% of HIV cases in a trial involving women and adolescent girls in Africa. This milestone signifies the first major successful trial of a potential new drug regimen aimed at preventing HIV. The long-acting shot, which only requires two injections per year, offers a more convenient option compared to daily pills or bi-monthly injections. This breakthrough could revolutionize HIV prevention, especially among women and adolescent girls, who are disproportionately affected by the virus.
The successful trial has already led to a surge in Gilead's stock by 8.3%, reflecting the potential impact of lenacapavir, which could generate over $1.7 billion in annual sales. The company is also conducting a second trial of lenacapavir for men who have sex with men, as well as transgender individuals, with results expected by late 2024. If successful, Gilead plans to seek regulatory approval for the preventive use of lenacapavir in the US and other countries.
