Mechanism of Action
12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action YEZTUGO is an HIV-1 antiretroviral agent with long-acting properties [see Microbiology (12.4) ]. 12.2 Pharmacodynamics Cardiac Electrophysiology At supratherapeutic exposures of lenacapavir (16-fold higher than the therapeutic exposures of YEZTUGO), YEZTUGO does not prolong the QTcF interval to any clinically relevant extent. 12.3 Pharmacokinetics The pharmacokinetic (PK) properties of lenacapavir are provided in Table 8 . The population PK parameter estimates of YEZTUGO after oral and subcutaneous administration to adults are provided in Table 9 . Similar exposures are achieved when YEZTUGO is administered subcutaneously in the abdomen or thigh. Table 8.

Interactions
- 7 DRUG INTERACTIONS Consult the Full Prescribing Information for important drug interactions with YEZTUGO. ( 7 , 12.3 ) 7.1 Effect of Other Drugs on YEZTUGO Lenacapavir is a substrate of P-gp, UGT1A1, and CYP3A. Strong or Moderate CYP3A Inducers Drugs that are strong or moderate inducers of CYP3A may significantly decrease plasma concentrations of lenacapavir, which may reduce the effectiveness of YEZTUGO. Therefore, dosage modifications (supplemental doses) of YEZTUGO are recommended when initiating strong or moderate CYP3A inducers [see Dosage and Administration (2.
