Description: Lenacapavir, also known as GS-6207, is a HIV-1 capsid inhibitor. Lenacapavir shows anti-HIV activity. Lenacapavir displays a mean EC50 of 50 pM (20-160 pM) against 23 HIV-1 clinical isolates from different subtypes in peripheral blood mononuclear cells (PBMCs). Lenacapavir demonstrated picomolar potency in vitro with no cross resistance to existing antiretroviral classes and potent antiviral activity in persons with HIV-1. In persons with HIV-1, there was no preexisting resistance to lenacapavir regardless of treatment history.

More Info: HIV-1 capsid inhibitors (of which lenacapavir is the first in class) has been postulated to have activity against multidrug resistant HIV-1 viral isolates. Initial results from the phase 3 trial CAPELLA (combining oral and subcutaneous lenacapavir alongside failing drug therapies) suggest that there may be a role for these novel agents in a cohort of patients living with HIV-1 infection (PLWH) for whom multidrug resistance has previously been a barrier to effective therapy.

Biological target: Lenacapavir (GS-6207) is a HIV-1 capsid inhibitor.
