CONTEXT 11beta-Hydroxysteroid dehydrogenase type 1 (11betaHSD1) is a promising target for the treatment of type 2 diabetes mellitus. 11betaHSD1 catalyzes the intracrine conversion of inactive cortisone to the active glucocorticoid cortisol. OBJECTIVE Demonstrating inhibition of 11betaHSD1 is challenging because there is no accessible way to directly(More)
This study evaluated the effect of a single 45-mg dose of dacomitinib (PF-00299804), an irreversible small-molecule inhibitor of human epidermal growth factor receptors-1, -2, and -4, on CYP2D6 activity in healthy volunteers (HV) using dextromethorphan (DM), a selective CYP2D6 probe. Fourteen male HVs were enrolled in this open-label, randomized,(More)
Lersivirine (UK-453,061) is a new nonnucleoside reverse transcriptase inhibitor currently being developed as a treatment for human immunodeficiency virus type 1 infection. Lersivirine shows potent activity against wild-type and clinically relevant drug-resistant strains. Previous studies have demonstrated that lersivirine is metabolized by glucuronidation(More)
BACKGROUND Lersivirine is a nonnucleoside reverse transcriptase inhibitor undergoing clinical development for the treatment of HIV-1. OBJECTIVE The goal of this study was to investigate the safety and tolerability of multiple oral doses of lersivirine administered to healthy male subjects to assist in the planning of longer term studies. METHODS This(More)
The relative bioavailability and bioequivalence of 20-mg doses of a pediatric formulation of sildenafil extemporaneous preparation suspension (EP; 10 mg/mL), the sildenafil 20-mg intact tablet and the crushed sildenafil 20-mg tablet mixed with apple sauce were assessed in a single-dose, randomized, open-label, 3-way crossover study with 18 healthy adult(More)
The objective of this study was to investigate the effect of a supratherapeutic dose of lersivirine (LRV) on corrected QT (QTc) interval using Fridericia's equation (QTcF) in healthy subjects. In this randomized, single-dose, placebo- and active-controlled 3-way crossover study, healthy adult males (n = 48) were randomized to receive LRV (2,400 mg),(More)
Lersivirine is a next-generation non-nucleoside reverse transcriptase inhibitor (NNRTI) with a unique resistance profile that exhibits potent antiretroviral activity against wild-type human immunodeficiency virus and clinically relevant NNRTI-resistant strains. Results from in vitro and in vivo investigations suggest that lersivirine is a cytochrome P450(More)
OBJECTIVE Lersivirine (UK-453,061) is a next-generation nonnucleoside reverse transcriptase inhibitor, active against wild-type HIV-1 and several nonnucleoside reverse transcriptase inhibitor-resistant strains. Four studies evaluated the pharmacokinetic (PK) interactions between lersivirine and various HIV-1 protease inhibitors. METHODS Four phase I(More)
Tofacitinib is a novel, oral JAK inhibitor that is being investigated as a targeted immunomodulator. Tofacitinib is predominantly metabolized by cytochrome P450 (CYP) 3A4 and to a lesser extent by CYP2C19. Two Phase 1, randomized, open-label, single sequence studies in 24 healthy subjects (12 per study) characterized the effects of fluconazole (moderate(More)
