A Study of Safety and Efficacy of Vaniprevir Administered With Pegylated-Interferon and Ribavirin in Japanese Participants With Chronic Hepatitis C Infection (7009-016)
2018年9月10日 更新者：Merck Sharp & Dohme LLC
A Phase II Randomized Placebo-controlled Study to Evaluate the Safety and Efficacy of MK-7009 Administered Concomitantly With Pegylated-Interferon and Ribavirin for 28 Days in Japanese Treatment-Experienced Patients With Chronic Hepatitis C Infection
The study evaluates safety and efficacy of vaniprevir (MK7009), when administered with Pegylated-Interferon (peg-IFN) and Ribavirin, in Japanese patients with Hepatitis C infection.
The primary hypotheses are that 1.) the proportion of patients achieving rapid viral response (RVR) in one or more of the vaniprevir treatment groups is superior to that in the placebo group, when each is administered concomitantly with pegylated interferon (peg-IFN) α-2a and ribavirin; and 2.) vaniprevir at the studied doses is well tolerated compared with placebo, when each is administered concomitantly with peg-IFN α-2a and ribavirin for 28 days.

Percentage of Participants Achieving Rapid Viral Response
大体时间：Week 4
|
Rapid viral response (RVR) is defined as undetectable hepatitis C virus ribonucleic acid (HCV RNA) at Week 4. Serum HCV RNA levels were measured using Roche COBAS TaqMan HCV Auto assay.
The limit of quantification was 1.2 log IU/mL (15 IU/mL) and the limit of detection was <1.2 log IU/mL, but with no specific value.
The Data-As-Observed (DAO) approach was used to handle missing data.

Change From Baseline in HCV RNA in log10 at Week 4
大体时间：Baseline and Week 4
|
Change from baseline in HCV RNA at Week 4 was calculated by subtracting Week 4 HCV RNA level from Baseline HCV RNA level.
HCV RNA is measured as International Units per milliliter (IU/mL).
Serum HCV RNA levels were measured using Roche COBAS TaqMan HCV Auto assay.
The DAO approach was used to handle missing data.
