Abstract
BACKGROUND & AIMS: The efficacy and safety of interferon-free regimens for the treatment of chronic hepatitis C virus (HCV) infections require further evaluation and comparison with those of interferon-containing regimens. We compared a regimen of peginterferon, ribavirin, and sofosbuvir with a regimen of simeprevir and sofosbuvir in patients with HCV infection and unfavorable treatment features. METHODS: We performed a prospective open-label study of 82 patients with chronic HCV genotype 1a infection and Child's grade A cirrhosis enrolled from 2 clinics at a single center in Atlanta, Georgia, from December 2013 through January 2014. Fifty patients (61%) had not responded to treatment withpeginterferon and ribavirin (null responders), and 32 (39%) were therapy naive; 39 (48%) were African American. Subjects were assigned randomly to groups given simeprevir (150 mg/day) and sofosbuvir (400 mg/day) (n = 58 in the final analysis) or peginterferon alfa 2b (1.5 mcg/kg/wk), ribavirin (1000-1200 mg/day), and sofosbuvir (400 mg/day) (n = 24 in the final analysis). Both regimens were given for 12 weeks. The primary trial end point was the proportion of patients with undetectable HCV-RNA levels 12 weeks after therapy completion (SVR12). RESULTS: A significantly greater percentage of patients (93%) given simeprevir and sofosbuvir achieved an SVR12 than those given the interferon-containing regimen (75%) (P = .02). Patients given the interferon-containing regimen had a significantly higher rate of virologic relapse than patients given simeprevir and sofosbuvir (P = .009), as well as worse self-reported outcomes and more side effects. Quality-of-life scores were higher in patients with SVR12 than those without, regardless of treatment regimen. CONCLUSIONS: In a prospective study of patients with chronic HCV genotype 1a infection and cirrhosis (48% African American and 61% prior null responders), a 12-week regimen of simeprevir and sofosbuvir produced a significantly higher rate of SVR12 and was better tolerated, with a lower viral relapse rate, than a 12-week regimen of peginterferon, ribavirin, and sofosbuvir. Clinicaltrials.gov no: NCT021683615.
