In the interim analysis of the pivotal phase III PURPOSE 1 trial, twice-yearly subcutaneous lenacapavir, a first-in-class, high-potency HIV-1 capsid inhibitor, shows 100-percent efficacy and superiority to background HIV (bHIV*) incidence and daily oral emtricitabine/tenofovir disoproxil fumarate (F/TDF**) for pre-exposure prophylaxis (PrEP) in HIV-negative cisgender women.

The two-drug regimen dolutegravir plus lamivudine (DTG/3TC) is as good as 3- or 4-drug antiretroviral therapy (ART) regimens at keeping viral load suppressed while helping avoid hepatitis B virus (HBV) reactivation in people living with HIV-1 who have past exposure to HBV but no immunity, according to a post hoc analysis of five phase 3/3b studies.

A substudy of the phase III FLAIR study has found comparable efficacy and pharmacokinetics for cabotegravir (CAB) plus rilpivirine (RPV) via subcutaneous (SC) administration relative to those via intramuscular (IM) gluteal injections among virally suppressed individuals living with HIV-1.
