    93
Randomized trial of Hepatitis C-genotype 1-infected patients with compensated cirrhosis comparing the standard of care (Peginterferon/Ribavirin/Sofosbuvir) versus the off-label combination of simeprevir+ sofosbuvir without Ribavirin.
Patients can be treatment naive or prior null response to Peg/RBV, and must be genotype subtype 1a.

Must have Child's Class A cirrhosis/compensated and no history of decompensation

Drug Pegylated Interferon alfa-2b

1.5 ugm/kg/week subcutaneously injected along with ribavirin and sofosbuvir for 12 weeks total

  • Other names: Pegintron

Drug Simeprevir

150 mg daily orally along with pegylated interferon and sofosbuvir for a total of 12 weeks

  • Other names: Olysio

Drug Ribavirin

1000-1200 mg daily divided twice daily for 12 weeks in combination with pegylated interferon and sofosbuvir

  • Other names: Ribavirin Ribasphere Ribapak
