Description

Lenacapavir (Sunlenca®) is a long-acting capsid inhibitor of human immunodeficiency virus type 1 (HIV-1) being developed by Gilead Sciences Inc. Lenacapavir is a multistage, selective inhibitor of HIV-1 capsid function that directly binds to the interface between capsid protein (p24) subunits in hexamers. Surface plasmon resonance sensorgrams showed dose-dependent and saturable binding of lenacapavir to cross-linked wild-type capsid hexamer with an equilibrium binding constant (KD) of 1.4 nM. Lenacapavir inhibits HIV-1 replication by interfering with multiple essential steps of the viral lifecycle, including capsid-mediated nuclear uptake of HIV-1 proviral DNA (by blocking nuclear import proteins binding to capsid), virus assembly and release (by interfering with Gag/Gag-Pol functioning, reducing production of capsid protein subunits), and capsid core formation (by disrupting the rate of capsid subunit association, leading to malformed capsids). It is available as an oral tablet and injectable solution, with the latter being a slow-release formulation to allow bi-annual subcutaneous administration. In August 2022, lenacapavir received its first approval in the EU for use in combination with other antiretroviral(s) in adults with multi-drug resistant HIV infection, for whom it is otherwise not possible to construct a suppressive anti-viral regimen. On December 22, 2022 the US Food and Drug Administration granted approval for Gilead Sciences’ Sunlenca (lenacapavir) plus other antiretroviral(s) to treat human immunodeficiency virus type 1 infection.

In Vitro Use Guide

Lenacapavir inhibits anti-IgM stimulated phosphorylation of AKT, BLNK, BTK, ERK, MEK, and PKCδ in human B cells with EC50 values of 24–51 nM. Functionally, GS-9876 inhibits anti-IgM mediated CD69 and CD86 expression on B-cells (EC50=112±10 nM and 164±15 nM, respectively) and anti-IgM /anti-CD40 co-stimulated B cell proliferation (EC50=108±55 nM). In human macrophages, GS-9876 inhibits IC-stimulated TNFα and IL-1β release (EC50=121±77 nM and 9±17 nM, respectively). Anti-CD3/anti-CD28 stimulated T cell proliferation is weakly inhibited (EC50=1291±398 nM), with selectivity >10-fold versus the inhibition of B cell proliferation.
