Drug Information available for: Sofosbuvir

Arm Intervention/treatment
Experimental: SOF/VEL
SOF/VEL for 12 weeks
400/100 mg FDC tablet(s) administered orally once daily
Other Names:
  • Epclusa®
  • GS-7977/GS-5816

Primary Outcome Measures :
  1. Percentage of Participants With Sustained Virologic Response (SVR) 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, 15 IU/mL) at 12 weeks after stopping study treatment.

  2. Percentage of Participants Who Permanently Discontinued Any Study Drug Due to an Adverse Event [ Time Frame: Up to Week 12 ]

Secondary Outcome Measures :
  1. Percentage of Participants With Virologic Failure [ Time Frame: Up to Posttreatment Week 12 ]

    Virologic failure was defined as the following:

    • On Treatment Virologic Failure: HCV RNA persistently ≥ LLOQ through 12 weeks of treatment (nonresponse), or
    • Relapse: HCV RNA ≥ LLOQ at Posttreatment Week 12 having achieved HCV RNA < LLOQ at end of treatment.
