Summary

This study will examine the safety, tolerability and plasma pharmacokinetics of multiple doses of MK-3281 in healthy male participants in Part I, and in Hepatitis C Virus (HCV)-infected male participants in Part II. The clinical efficacy of MK-3281, as measured by viral load reduction, will also be assessed in Part II. The primary hypothesis is that twice daily administration of MK-3281 for 10 days in healthy adult male participants and for 7 days in HCV-infected male participants is sufficiently safe and well tolerated, based on assessment of clinical and laboratory adverse experiences, to permit continued clinical investigation.

The results of this study will guide dose selection for future studies in both healthy participants and HCV-infected participants.

Conditions

  • Hepatitis C

Interventions

DRUG

MK-3281

MK-3281 capsule administered orally BID for 7 or 10 consecutive days depending on randomized dose. The PM dose of MK-3281 was not administered on Day 7 (for HCV-infected males) or Day 10 (for healthy males)

DRUG

Placebo to MK-3281

Dose-matched placebo to MK-3281 capsule administered orally BID for 7 or 10 consecutive days depending on randomized dose of MK-3281 in serial panel. The PM dose of matched placebo was not administered on Day 7 or 10 (depending upon allocation).
