Letermovir is a human cytomegalovirus terminase inhibitor for cytomegalovirus infection prophylaxis in hematopoietic stem cell transplant recipients. Posaconazole (POS), a substrate of glucuronosyltransferase and P-glycoprotein, and voriconazole (VRC), a substrate of CYP2C9/19, are commonly administered to transplant recipients. Because coadministration of these azoles with letermovir is expected, the effect of letermovir on exposure to these antifungals was investigated.

This randomized, open-label, 4-period crossover study compared single-dose pharmacokinetics of MF 800 µg; F 20 µg; MF 800 µg + F 20 µg coadministered (MF + F); and MF 800 µg/F 20 µg (MF/F) FDC in healthy subjects. MF, F, and MF + F were administered from single-ingredient MDI devices.

Methods: In a randomized, open-label, placebo-controlled, parallel group study, 66 patients with mild to moderate asthma received one of the following four treatments bid through an MDI for 42 days: mometasone furoate/formoterol (MF/F) 200 μg/10 μg, MF/F 400 μg/10 μg, fluticasone propionate/salmeterol (FP/S) 460 μg/42 μg, or placebo. Plasma cortisol concentrations were measured over 24 h on days -1 (baseline) and 42.
