  • Sovaldi®
  • GS-7977
  • PSI-7977

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 12 Weeks After Discontinuation of Therapy (SVR12)
Time Frame: Posttreatment Week 12
SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ, ie, < 25 IU/mL) 12 weeks following the last dose of study drug. Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.
Posttreatment Week 12
Adverse Events Leading to Permanent Discontinuation of Study Drug(s)
Time Frame: Up to 24 weeks
The percentage of participants experiencing an adverse event leading to permanent discontinuation of study drug(s) was analyzed.
Up to 24 weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response at 4 and 24 Weeks After Discontinuation of Therapy (SVR4 and SVR24)
Time Frame: Posttreatment Weeks 4 and 24
SVR4 and SVR24 was defined as HCV RNA < LLOQ at 4 and 24 weeks following the last dose of study drug, respectively. Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.
Posttreatment Weeks 4 and 24
Percentage of Participants Experiencing Viral Breakthrough or Viral Relapse
Time Frame: Up to Posttreatment Week 24

Viral breakthrough was defined as having confirmed detectable HCV RNA levels (HCV RNA > LLOQ) after having previously had undetectable HCV RNA levels (HCV RNA < LLOQ) while on treatment.

Viral relapse was defined as having achieved undetectable HCV RNA levels (HCV RNA < LLOQ) at end of treatment, but did not achieve an SVR.

Data for this outcome measure was not collected for the Placebo 12 Weeks (GT2/3) group.

Up to Posttreatment Week 24
