Abstract
Treatment with an all‐oral interferon‐free antiviral regimen using simeprevir and sofosbuvir with or without ribavirin (RBV) for 12 weeks resulted in high sustained virologic response (SVR) rates along with minimal adverse events in non–liver transplant (LT) patients with hepatitis C virus (HCV) genotype 1 infection. This is the first multicenter report on the efficacy, safety, and tolerability of this regimen in LT recipients. A total of 123 patients (76% male, 74% white, 60% genotype 1a, 30% METAVIR F3‐F4, 4% decompensation, 11% cholestatic recurrence, 7% had kidney transplant, and 82% previously failed pegylated interferon/RBV‐based regimens) received treatment and were followed for a median of 30 weeks (range 12‐53 weeks). The median time from LT to treatment was 32 months (range 2‐317 months). Tacrolimus was the primary immunosuppression in 91% of patients. Minimal immunosuppression dose adjustments were required. An SVR 12 weeks after treatment completion (SVR12) was achieved in 90% of patients (95% confidence interval 84%‐96%). In patients with genotype 1a infection, the SVR12 rate was significantly lower in those with METAVIR F3‐F4 (71%) compared to those with F0‐F2 (91%). Half of the patients achieved undetected HCV RNA at treatment week 4, and their SVR12 rate was significantly higher (96%) compared to those with detectable HCV RNA (83%). Treatment was very well tolerated with mild degrees of adverse events, except for one death possibly due to drug‐induced lung injury. In the 25 patients who received RBV, 72% developed anemia requiring intervention. Conclusion: An all‐oral interferon‐free antiviral regimen using simeprevir and sofosbuvir with or without RBV for 12 weeks was very well tolerated and resulted in excellent SVR12 rates in LT recipients with HCV genotype 1 infection.
