The efficacy and safety of SUNLENCA in heavily treatment-experienced participants with multidrug resistant HIV-1 is based on 52-week data from CAPELLA, a randomized, placebo-controlled, double-blind, multicenter trial (NCT 04150068). CAPELLA was conducted in 72 heavily treatment-experienced participants with multiclass resistant HIV-1. Participants were required to have a viral load ≥ 400 copies/mL, documented resistance to at least two antiretroviral medications from each of at least 3 of the 4 classes of antiretroviral medications (NRTI, NNRTI, PI and INSTI), and ≤ 2 fully active antiretrovi...

The following adverse reactions are discussed in other sections of the labeling: Immune Reconstitution Syndrome [see Warnings and Precautions (5.1) ] Injection Site Reactions [see Warnings and Precautions (5.3) ]. Most common adverse reactions (incidence greater than or equal to 3%, all grades) are nausea and injection site reactions.

Concomitant administration of SUNLENCA with strong CYP3A inducers is contraindicated due to decreased lenacapavir plasma concentrations, which may result in the loss of therapeutic effect and development of resistance to SUNLENCA [see Drug Interactions (7.1) ] . Concomitant administration of SUNLENCA is contraindicated with strong CYP3A inducers. ( 4 )

Immune reconstitution syndrome: May necessitate further evaluation and treatment. ( 5.1 ) Residual concentrations of lenacapavir may remain in systemic circulation for up to 12 months or longer. Counsel patients regarding the dosing schedule; non-adherence could lead to loss of virologic response and development of resistance. ( 5.2 ) May increase exposure and risk of adverse reactions to drugs primarily metabolized by CYP3A initiated within 9 months after the last subcutaneous dose of SUNLENCA....
