Background & AimsPatients with chronic hepatitis C virus (HCV) infection and cirrhosis have a higher risk for liver-related complications and have historically been more difficult to cure than patients without cirrhosis. We evaluated the safety and efficacy of ombitasvir/paritaprevir/ritonavir and dasabuvir, without ribavirin, for 12 weeks in patients with HCV genotype 1b infection and compensated cirrhosis.MethodsTreatment-naïve and peginterferon/ribavirin treatment-experienced patients received 12 weeks of ombitasvir/paritaprevir/ritonavir (25/150/100 mg once daily) and dasabuvir (250 mg twice daily). Key inclusion criteria were hemoglobin ⩾10 g/dl, albumin ⩾2.8 g/dl, platelet count ⩾25 Ã 109/L, creatinine clearance ⩾30 ml/min, and Child-Pugh score ⩽6. Efficacy was assessed by the percentage of patients achieving SVR (HCV RNA <25 IU/ml) 12 weeks post-treatment (SVR12). Efficacy and safety were assessed in all patients receiving study drug.ResultsSixty patients with HCV genotype 1b infection and cirrhosis received treatment. The study population comprised 62% male, 55% treatment-experienced, 83% with IL28B non-CC genotype, 22% with platelet count <90 Ã 109/L, and 17% with albumin <3.5 g/dl. All 60 patients completed treatment, and SVR12 was achieved in 100% (95% CI, 94.0-100%) of patients. The most common adverse events were fatigue (22%), diarrhea (20%), and headache (18%). Only one patient (1.7%) experienced a serious adverse event. Laboratory abnormalities were infrequently observed and not clinically significant.ConclusionsThe HCV regimen of ombitasvir/paritaprevir/ritonavir and dasabuvir without ribavirin for 12 weeks achieved 100% SVR12 and was well tolerated in HCV genotype 1b-infected patients with cirrhosis, suggesting that this 12-week ribavirin-free regimen is sufficient in this population.
