FDA Approves Gilead’s Bixlenvo for HIV Treatment, Expanding Options for Complex Regimens — Gilead Sciences, Inc.

Event summary

FDA approved Gilead’s Bixlenvo™ (bictegravir/lenacapavir) as a once-daily single tablet regimen for virologically suppressed adults with HIV, including those on complex regimens.
Approval based on Phase 3 ARTISTRY-1 and ARTISTRY-2 trials, showing comparable efficacy and tolerability at Week 48.
Bixlenvo combines bictegravir (INSTI) with lenacapavir (capsid inhibitor), offering a novel mechanism with no cross-resistance to other antiretrovirals.
ARTISTRY-1 enrolled the oldest study population in a Phase 3 HIV-1 treatment trial, with a median age of 60 years and extensive treatment experience.
Bixlenvo requires a two-day initiation dose with Sunlenca®, followed by once-daily oral administration.

The big picture

The approval comes amid a broader industry shift toward simplified, once-daily regimens and novel mechanisms to address resistance. Gilead’s focus on expanding treatment options aligns with its goal of ending the HIV epidemic through scientific innovation and partnerships.
