Abstract
INTRODUCTION: Glecaprevir/pibrentasvir is approved for treating chronic hepatitis C virus (HCV) genotypes (GT) 1-6. We evaluated real-world effectiveness, safety, and patient-reported outcomes of glecaprevir/pibrentasvir in underserved patient populations, focusing on persons who use drugs infected with HCV. METHODS: Data were pooled from nine countries (13 November 2017-31 January 2020). Patients had HCV GT1-6, with or without compensated cirrhosis, with or without prior HCV treatment and received glecaprevir/pibrentasvir consistent with local label at their physician's discretion. Patients with prior direct-acting antiviral exposure were excluded from efficacy and quality-of-life analyses. The percentage of patients achieving sustained virologic response at post-treatment week 12 (SVR12) was assessed. Mean changes from baseline to SVR12 visit in 36-Item Short-Form Health Survey mental and physical component summary scores were reported. Safety was assessed in patients receiving at least one dose of glecaprevir/pibrentasvir. RESULTS: Of 2036 patients, 1701 (83.5%) received 8-week glecaprevir/pibrentasvir. In 1684 patients with sufficient follow-up, SVR12 rates were 98.0% (1651/1684) overall, 98.1% (1432/1459) in 8-week treated patients, 97.0% (519/535) in persons who use drugs, and greater than 95% across subgroups. Mean changes from baseline in mental and physical component summary scores were 3.7 and 2.4, respectively. One glecaprevir/pibrentasvir-related serious adverse event was reported; six glecaprevir/pibrentasvir-related adverse events led to discontinuation. CONCLUSIONS: Glecaprevir/pibrentasvir was highly effective, well tolerated, and improved quality of life in HCV-infected persons who use drugs and other underserved patients. TRIAL REGISTRATION: These multinational post-marketing observational studies are registered with ClinicalTrials.gov, number NCT03303599.
