Abstract

AbstractThis phase 1 first-in-human study evaluated the safety, tolerability, and pharmacokinetics of MK-1088, a novel, small-molecule dual inhibitor of adenosine A2A and A2B receptors. Healthy adult participants were enrolled in two panels (n = 8 each) and randomly assigned to receive MK-1088 (n = 6) or placebo (n = 2) orally in each of five treatment periods. Participants in panel A received single ascending doses of MK-1088 at 1, 10, 50, and 150 mg or placebo in a fasted or fed (50 mg only) state. Participants in panel B received MK-1088 at 3, 25, 100, and 224 mg or placebo in a fasted state. Primary objectives were to evaluate safety, tolerability, and plasma pharmacokinetics following a single dose of MK-1088. The secondary objective was to evaluate the effects of a high-fat meal on pharmacokinetics. All participants (n = 16) completed the study (median age: 33 years [range: 20–43]; all were male). Treatment-related adverse events (AEs) occurred in 1 of 6 (17%), 4 of 6 (67%), 4 of 6 (67%), and 2 of 6 (33%) participants after receiving MK-1088 at 3, 25, 100, and 224 mg, respectively. No serious AEs or deaths due to any cause occurred. MK-1088 was rapidly absorbed after a single dose; half-life was ~ 11 h in the 100–224 mg dose range. The target concentration at 12 h (> 0.3 µM) was exceeded at the 50-mg dose level. MK-1088 plasma pharmacokinetics increased dose proportionately. A high-fat meal did not significantly affect pharmacokinetics at the 50-mg dose. MK-1088 was well tolerated and demonstrated dose-proportional pharmacokinetic properties that were not affected by a high-fat meal.
