Safety, Tolerability, and Efficacy of 24 Weeks Simeprevir+Sofosbuvir for Chronic Hepatitis C Genotype 1

October 12, 2016 updated by: Mindie H. Nguyen, Stanford University

Safety, Tolerability, and Efficacy of Simeprevir 150 mg Daily Plus Sofosbuvir 400 mg Daily for 24 Weeks in Patients With Chronic Hepatitis C Genotype 1 With CPT Score of 6 or Lower Who Are IFN-Intolerant or Unwilling to be Treated With IFN

The goal of this pilot study is to examine both efficacy and tolerability in patients with HCV genotype 1 and mild decompensation with Child-Pugh-Turcott score of 6 or lower. The CPT score is used to assess the prognosis of chronic liver diseases, as well as the required strength and treatment and necessity of liver transplantation. A higher CPT score denotes higher necessity of liver transplantation.

Detailed Description

Key objectives of this study include:

  1. To describe efficacy (SVR) in a special population of patients with chronic hepatitis C who are not willing or not candidates for IFN-based therapy.
  2. To describe safety, tolerability, and treatment persistency in this patient population with advanced liver disease.
