Real-World Effectiveness of 8-Week Glecaprevir/Pibrentasvir in Treatment-Naïve, Compensated Cirrhotic HCV Patients

Introduction: The EXPEDITION-8 clinical trial has demonstrated that treatment-naïve patients with compensated cirrhosis (TN/CC) of HCV genotypes 1–6 can achieve a 98% intent-to-treat sustained virologic response rate 12 weeks post-treatment with an 8-week glecaprevir/pibrentasvir (G/P) regimen. Further real-world evidence is needed to support the effectiveness of 8-week G/P in a clinical practice setting and to consolidate these treatment recommendations. The aim of this study is to contribute real-world evidence for the effectiveness of an 8-week G/P treatment in TN/CC patients with HCV genotypes 1–6. Methods: Retrospective real-world data from 494 TN/CC patients with HCV genotypes 1–6 were collected between August 2017 to December 2020 from the Symphony Health Solutions administrative claims database. Demographic and clinical characteristics were collected at baseline. Patients were required to have a follow-up HCV ribonucleic acid level at least 8 weeks or more after the end of treatment. The percentage of patients achieving a sustained virologic response (SVR) is reported. Results: The majority of patients were male (58%) and Caucasian (40%), with a mean age of 58 years; 74%, 12%, 12%, and 1% of patients were HCV genotype 1, 2, 3, and 4–6 infected, respectively. SVR was achieved in 95.5% of all patients. Across patient subgroups, SVR was achieved in 95.6% of patients with HCV genotype 3 and in 93% of HCV patients with a recent diagnosis of illicit drug use or abuse (within 6 months prior to G/P initiation). Conclusion: Early real-world evidence indicates high effectiveness of the 8-week G/P regimen in TN/CC patients of HCV genotypes 1–6 from a large US claims database.
