Gilead inches toward regulatory submission for twice-yearly injectable HIV preventative
Gilead's twice-yearly injectable HIV-1 capsid inhibitor, lenacapavir, has reduced HIV infections by 96% in a second phase 3 trial, according to an interim analysis.
Among 2,180 participants, only two HIV cases were reported, with lenacapavir showing superior efficacy over daily Truvada. The trial, involving cisgender men and gender-diverse individuals, highlights the potential of lenacapavir as a more convenient HIV prevention option.
The PURPOSE 2 trial met its efficacy targets, showing lenacapavir’s ability to reduce infection rates significantly when compared to background HIV incidence and daily Truvada. In response, Gilead halted the blinded phase of the trial early, offering lenacapavir to all participants. With its twice-yearly dosing, lenacapavir addresses key issues like daily pill adherence, offering a simpler, more flexible approach to HIV prevention.
Lenacapavir’s infrequent dosing is a major advancement, with the potential to significantly improve quality of life for those at risk of HIV. By reducing the need for daily medication, it offers greater convenience and reduces the stigma some individuals face in maintaining daily pill regimens, providing an easier path to sustained prevention.
As HIV remains a global challenge, particularly in high-risk communities, lenacapavir could become a transformative tool in expanding prevention efforts. Gilead plans regulatory filings to support approval of the first twice-yearly HIV prevention option, with the goal of launching it in 2025. — Andrea Corona
