Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care (Pegylated-interferon Alpha and Ribavirin)

Safety and Efficacy of Daclatasvir (BMS-790052) Plus Standard of Care (Pegylated-interferon Alpha and Ribavirin)

A Phase 2a Study of BMS-790052 in Combination With Peginterferon Alfa-2a (Pegasys®) and Ribavirin (Copegus®) in Treatment Naive Subjects With Chronic Hepatitis C Virus Genotype 1

The purpose of this study is to identify 1 or more doses of daclatasvir, which when used in combination with pegylated interferon alpha and ribavirin, are safe and demonstrate sufficient anti-hepatitis C virus activity.

eRVR was defined as undetectable hepatitis C virus RNA less than the lower limit of detection (10 IU/mL) at Weeks 4 and 12.

RVR was defined as undetectable hepatitis C virus (HCV) RNA ie, HCV RNA less than the lower limit of detection (10 IU/mL) at Week 4.

EVR was defined as a ≥2 log10 decrease in hepatitis C virus (HCV) RNA from baseline at Week 12 , or HCV RNA <10 IU/mL for participants with baseline HCV RNA <1000 IU/mL.

Number of Participants With Serious Adverse Events (SAEs), Discontinuations Due to Adverse Events (AEs), and Treatment-related AEs and Who Died in Treatment Phase

An AE was defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a patient or clinical investigation participant administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization. Treatment-related AE was defined as an AE that had certain, probable, possible, or unknown relationship to study drug.

SAE: From Day 1 up to 30 days after last dose of study drug, AE: From Day 1 to 7 days after last dose of study drug

Number of Participants With Serious Adverse Events (SAEs), Discontinuations Due to Adverse Events (AEs), and Treatment-related AEs and Who Died in Follow-up Period

An AE was defined as any new untoward medical occurrence or worsening of a preexisting medical condition in a patient or clinical investigation participant administered an investigational (medicinal) product and that does not necessarily have a causal relationship with this treatment. SAE was defined as a medical event that at any dose resulted in death, persistent or significant disability/incapacity, or drug dependency/abuse; was life-threatening, an important medical event, or a congenital anomaly/birth defect; or required or prolonged hospitalization. Treatment-related AE was defined as an AE that had certain, probable, possible, or unknown relationship to study drug.
