Drug Interactions between AccessPak for HIV PEP Basic and vimseltinib

Consumer information for this interaction is not currently available.

GENERALLY AVOID: Coadministration with vimseltinib may increase the plasma concentrations of drugs that are substrates of the P-glycoprotein (P-gp) efflux transporter. The proposed mechanism, based on in vitro data, involves decreased clearance due to inhibition of P-gp by vimseltinib. Based on model-informed drug interaction studies, coadministration of the P-gp substrate dabigatran with vimseltinib (30 mg twice weekly) is predicted to increase the systemic exposure (AUC) and peak plasma concentration (Cmax) of dabigatran by 2 to 3-fold. However, if dabigatran is administered 4 hours after vimseltinib (30 mg twice weekly), the AUC and Cmax are predicted to increase by only up to 1.3-fold. Clinical data are not available.

MANAGEMENT: Concomitant use of vimseltinib with P-gp substrates should generally be avoided. If coadministration is considered necessary, vimseltinib should be taken at least 4 hours prior to the P-gp substrate. The individual product labeling of the P-gp substrate should be consulted for further guidance.
