Study to Determine the Safety and Effectiveness of Antiviral Combination Therapy to Treat Hepatitis C Virus (HCV) in Patients Who Have Previously Not Received the Standard of Care

September 23, 2015 updated by: Bristol-Myers Squibb

Parallel, Open-Label, Randomized Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of PSI-7977 in Combination With BMS-790052 With or Without Ribavirin in Treatment Naive Subjects Chronically Infected With Hepatitis C Virus Genotypes 1, 2, or 3

The purpose of the study is to determine whether therapy with the combination of PSI-7977 and daclatasvir (BMS-790052) with or without ribavirin is effective in treating hepatitis C virus (HCV) infection when given for 12 or 24 weeks as measured by sustained virologic response with undetectable HCV RNA 12 weeks post treatment

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response at Post Treatment Week 12 (SVR12)
Time Frame: Follow-up Week 12
SVR12 was defined as hepatitis C virus (HCV) RNA less than the lower limit of quantitation, target detected or target not detected (ie, HCV RNA <25 IU/mL) at follow-up Week 12. DCV=daclatasvir, SOF=sofosbuvir.
Follow-up Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response at Post Treatment Week 24 (SVR24)
Time Frame: Follow-up Week 24
SVR24 was defined as participant's hepatitis C virus RNA less than the lower limit of quantitation, target detected or target not detected at follow-up Week 24. DCV=daclatasvir, SOF=sofosbuvir.
Follow-up Week 24
Percentage of Participants With Viral Breakthrough During the Treatment Period
Time Frame: First dose of study drug (Day 1) up to end of treatment period (up to 12 or 24 weeks, depending on treatment group)
Viral breakthrough is defined as any confirmed increase in viral load ≥1 log from nadir or any confirmed hepatitis C virus RNA levels ≥25 IU/mL on or after Week 8.
First dose of study drug (Day 1) up to end of treatment period (up to 12 or 24 weeks, depending on treatment group)
Percentage of Participants Who Experienced Viral Relapse During Follow-up Period
Time Frame: Day 1 of follow-up period (Week 13 or 25, depending on treatment group) to end of follow-up period (up to 48 weeks)
Viral relapse during follow-up is defined as any confirmed quantifiable hepatitis C virus (HCV) RNA ≥25 IU/mL with HCV RNA levels less than the lower limit of quantitation, target detected or target not detected, ie, HCV RNA <25 IU/mL at the end of treatment.
Day 1 of follow-up period (Week 13 or 25, depending on treatment group) to end of follow-up period (up to 48 weeks)
Change From Baseline in log10 Hepatitis C Virus (HCV) RNA at Follow-up Week 24
Time Frame: Baseline, Follow-up week 24
Change from baseline in log10 HCV RNA at scheduled sampling time.
Baseline, Follow-up week 24
Number of Participants Who Died and With Serious Adverse Events (SAEs) and Grade 3-4 Adverse Events (AEs), During the Treatment Period Prior to Addition of Rescue Therapy
Time Frame: First dose of study drug (Day 1) up to the start of rescue therapy (12 or 24 weeks, depending on treatment group)
AE was defined as any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that does not necessarily have a causal relationship with 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. Based on the severity, AEs were categorized as Grade (Gr) 1=Mild, Gr 2=Moderate, Gr 3=Severe, Gr 4=Very severe.
First dose of study drug (Day 1) up to the start of rescue therapy (12 or 24 weeks, depending on treatment group)
