A Multiple Dose Study to Evaluate the Safety and Efficacy of MK-2748 in Hepatitis C-Infected Participants (MK-2748-002 AM1)
January 21, 2015 updated by: Merck Sharp & Dohme LLC
A Multiple Dose Study to Evaluate the Safety, Pharmacokinetics and Pharmacodynamics of MK-2748 in Hepatitis C-Infected Participants
This is a multiple dose study of the safety and efficacy of MK-2748 to be done in 2 Parts.
Part I will enroll genotype 1 (GT1) hepatitis C virus (HCV)-infected participants and Part II will enroll genotype 3 (GT3) HCV-infected participants.
Both Parts may run concurrently or may be staggered.
