Exclusion criteria: - Infection/co-infection: HCV genotype other than 1b or 4, Human immunodeficiency virus type 1 or 2 - Liver disease of non-HCV etiology: Any evidence of liver disease of non-HCV etiology. This includes, but is not limited to, acute hepatitis A, hepatitis B (hepatitis B surface antigen positive), drug- or alcohol-related liver disease, autoimmune hepatitis, hemochromatosis, Wilson?s disease, alpha-1 antitrypsin deficiency, non-alcoholic steatohepatitis, primary biliary cirrhosis, or any other non-HCV liver disease considered clinically significant by the investigator - Hepatic decompensation: History or evidence of clinical hepatic decompensation (presence of ascites, bleeding varices or hepatic encephalopathy) - Organ transplantation/renal replacement therapy: Prior organ transplant (other than cornea, hair transplant or skin graft), except for history of kidney transplant with subsequent renal failure requiring hemodialysis and for which use of immunosuppressants has been discontinued; Considered for kidney transplant or imminent renal replacement therapy (including intermittent hemodialysis; continuous hemofiltration and hemodialysis; and peritoneal dialysis) for participants with severe renal impairment within a time frame that overlaps with study participation - Key protocol defined laboratory abnormalities

Design outcomes

Primary

MeasureTime frame
Secondary Objective: To evaluate safety and tolerability of a 12-week treatment regimen containing SMV and DCV. To evaluate on-treatment virologic response of a 12-week treatment regimen containing SMV and DCV. To evaluate the efficacy (SVR4 and SVR24) of a 12-week treatment regimen containing SMV and DCV. To evaluate the frequency of on-treatment failure during a 12-week treatment regimen containing SMV and DCV. To evaluate the frequency of viral relapse after a 12-week treatment regimen containing SMV and DCV. To assess changes from baseline in the HCV NS3/4A and NS5A sequence in subjects not achieving SVR. To evaluate plasma PK of SMV in subjects with severe renal impairment or ESRD on hemodialysis using a population PK modeling approach. Additional secondary objectives are listed in the protocol;Primary end point(s): Percentage of Participants With Sustained Virologic Response at Week 12 After End of Treatment (SVR12);Timepoint(s) of evaluation of this end point: 12 weeks after end of treatment (EOT) (Week 12 of follow-up phase);Main Objective: The primary objective is to evaluate the efficacy (SVR12) of a 12-week treatment regimen containing SMV and DCV in subjects with chronic HCV genotype 1b or 4 infection and either severe renal impairment or ESRD on hemodialysis.
