The FDA granted tentative approval to Dr. Reddy’s generic twice-yearly lenacapavir for HIV PrEP, the first generic version of the drug, for 120 low- and middle-income countries at about $40 per person per year.
The tentative approval came 16 months after Gilead’s originator was approved, and first generic supplies are expected to reach countries by the end of 2026.
Compared with daily oral FTC/TDF, lenacapavir reduced the risk of HIV by 100% in PURPOSE 1 and by 89% in PURPOSE 2, but experts caution that low prices alone won’t be enough without health systems ready to deliver it.
The partners are coordinating rollout with national governments, the Global Fund, the US Bureau of Global Health Security and Diplomacy, the Gates Foundation, and community groups.2 According to CHAI CEO Neil Buddy Shah, MD, more than 125,000 people in Africa have already started on lenacapavir.2
“This should be the new standard for global health,” Shah said in a statement, citing the 16-month gap between originator and generic approval.2
What PURPOSE 1 and PURPOSE 2 Showed for Twice-Yearly Lenacapavir PrEP
As Contagion has reported, twice-yearly lenacapavir outperformed daily oral emtricitabine/tenofovir disoproxil fumarate (FTC/TDF). It reduced the risk of incident HIV by 100% in PURPOSE 1 and by 89% in PURPOSE 2.3 Injection site reactions were the most common adverse effect, occurring in 83.2% and 68.8% of lenacapavir recipients in the two trials, and most were mild.3
Adherence data are especially relevant where daily oral PrEP uptake has lagged. In PURPOSE 1 (NCT05568355), more than 90% of women received their lenacapavir injections on time. Only 4% of daily oral PrEP users achieved high and sustained adherence, Jared Baeten, MD, PhD, senior vice president of clinical development at Gilead, told Contagion.4
Baeten also emphasized oral daily PrEP remains appropriate for many patients, with the clinical goal being expanded choice.5 Gilead has since submitted a once-weekly oral lenacapavir formulation for PrEP to the FDA.4
Delivery remains a hurdle. Saiqa Mullick, PhD, director of implementation science at Wits RHI, cautioned “an affordable drug alone is not enough.” She added countries need health systems ready to deliver new prevention options.2
The approval comes as global prevention programs absorb funding cuts. According to UNAIDS data, people receiving PrEP at least once across 62 countries fell from 3.3 million in 2024 to 2.1 million in 2025.2 New HIV infections declined to approximately 1.2 million in 2025.2
