Mechanism of action

Lenacapavir targets the HIV capsid, a critical viral structure that protects the viral genome during early infection. By inhibiting capsid uncoating, the drug prevents the release of viral RNA into the host cell cytoplasm, thereby blocking reverse transcription and integration. This novel mechanism of action is distinct from existing antiretroviral classes and provides activity against drug-resistant HIV strains.
