Safety and Efficacy of Ledipasvir/Sofosbuvir Fixed-Dose Combination in Adults With Chronic HCV and HBV Coinfection

18. februar 2020 oppdatert av: Gilead Sciences

A Phase 3b Open-Label Study of Ledipasvir/Sofosbuvir Fixed-Dose Combination for 12 Weeks in Subjects With Chronic Genotype 1 or 2 Hepatitis C Virus (HCV) and Hepatitis B Virus (HBV) Coinfection

The primary objectives of this study are to determine the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) in adults with chronic genotype 1 or 2 HCV infection who are coinfected with HBV in Taiwan.

FibroScan is a non-invasive device that assesses the hardness (or stiffness) of the liver using the technique of transient elastography. FibroScan results range from 2.5 kPa to 75 kPa with higher scores indicating greater liver stiffness. Per protocol, cirrhosis status was determined as follows:

  • Presence of cirrhosis = FibroScan result of > 12.5 kPa
  • Absence of cirrhosis = FibroScan result of ≤ 12.5 kPa
