Examining the clinical course of genotype 1 chronic hepatitis C patients treated with the cosmos regimen: including patients with advanced liver disease and East Asian ancestry

摘要

The COSMOS study was a phase 2a clinical trial that showed high cure rates of genotype 1 chronic hepatitis C (CHC) and a favorable side effect profile using a 12-week regimen of simeprevir + sofosbuvir (SIM + SOF). Given the small number of patients treated with the SIM + SOF regimen in the COSMOS trial, there is uncertainty regarding the efficacy and safety of this combination therapy. We now report our experience with the COSMOS regimen in the multiethnic population of Hawaii, including patients of East Asian ancestry and with decompensated cirrhosis.
