Safety, tolerability, and pharmacokinetics of single- and multiple-dose administration of islatravir (MK-8591) in adults without HIV.

ABSTRACT: Islatravir (MK-8591) is a nucleoside analogue in development for the treatment and prevention of HIV-1. Two phase 1 trials were conducted during initial evaluation of islatravir: rising single doses (Study 1) and rising multiple doses (Study 2) of oral islatravir in male and female participants without HIV (aged 18-60 years). Safety, tolerability, and pharmacokinetics of islatravir (plasma) and islatravir-triphosphate (peripheral blood mononuclear cells) were assessed. In Study 1, 24 participants, assigned to 1 of 3 panels, received alternating single doses of islatravir in a fasted state from 5 mg to 400 mg, or placebo, over 3 dosing periods; a 30 mg dose was additionally assessed following a high-fat meal. In Study 2, 8 participants per dose received 3 once-weekly doses of 10, 30, or 100
