Brief summary

This study will determine if MK-3614, given as single doses, is safe and well tolerated in healthy males and male participants with mild to moderate hypertension.

Detailed description

Up to three planned panels of either 8 healthy participants (Panels A and B) or 8 participants with mild to moderate hypertension (Panel C) will be enrolled. In Panels A and B, 8 participants will alternately receive single rising doses of MK-3614 or placebo. All doses will be administered in the fasted state, except Panel A, Period 3 in which a standard high-fat breakfast provided approximately 30 minutes prior to dosing. Panel A will begin first. At least 3 days will elapse before participants in the alternate panel (Panel B) will receive the next higher dose. In Panel C, 8 mild to moderate hypertensive male participants will receive single rising doses of MK-8892 or placebo. For all panels, there will be at least 7 days washout between treatment periods for any given participant. Participants may only be enrolled in one panel of the study. All participants in periods of all panels (with exception of 0.25 mg fasted/fed periods) will be randomly assigned to either study drug or placebo, i.e., a participant could be assigned to receive study drug in one period and placebo in another. As per the protocol allocation plan, the same participants will receive 0.25 mg MK-3612 in a fasted and fed state.

Participant flow

Recruitment details

Three panels, each consisting of 8 participants (8 healthy young males in Panel A and Panel B; and 8 with mild-to-moderate hypertension in Panel C) were randomized to receive either MK-3614 or matching placebo in a 3:1 ratio, respectively, in up to 4 treatment periods in Panel A, Panel B and Panel C.

Pre-assignment details

Each period of each panel (with exception of 0.25 mg fasted/fed periods) will be re-randomized to receive either study drug or placebo, i.e., a participant could be assigned to receive study drug in one period and placebo in another. The same participants will receive 0.25 mg MK-3614 in a fasted and fed state.
