Real-life Data of Glecaprevir/Pibrentasvir in Chronic Hepatitis C Patients: A Single-center Study

Abstract

Background: Glecaprevir/pibrentasvir (G/P) is a pangenotypic direct-acting antiviral (DAA) drug with a high resistance barrier. It has been used in patients with chronic hepatitis C in Turkey since March 2019. This drug’s efficacy and safety data in Turkey are very limited, and there are not enough studies on real-life data. Objectives: In this study, we aim to present real-life data, efficacy, and safety for our patients. Methods: In this retrospective, observational, single-center study, 116 patients who were started on G/P (100mg/40mg) oral therapy at the infectious diseases clinic between March 2019 and December 2021 due to HCV were included. Of the 116 patients included in the study, 92 were analyzed. Demographic data of the patients, previous treatment experience, drug use, viral load (HCV RNA levels at the 4th week of treatment and 12th week after treatment), and viral genotype data were obtained retrospectively from the automation system. Statistical analysis IBM SPSS version 21.0 statistical package program was used. Results: Seventy-one (77.2%) of the patients were male, and 21 (22.8%) were female, with a mean age of 47.4 (18-89). Genotype distribution of patients 8.7% (n = 8) type 1a, 31.5% (n = 29) type 1b, 26.1% (n = 24) type 2, 22.9% (n = 21) type 3, 10.9% (n = 10) were type 4, 8.7% (n = 8) of the patients were treatment-experienced. In our study, there were no patients with cirrhosis. SVR-12 could not be obtained from a patient infected with only genotype 1a. In addition, this patient was co-infected with Hepatitis B. No side effects were observed in any of the patients that required treatment discontinuation. The SVR-12 rate was 98.6% with patients per protocol analysis (PP), but the SVR-12 rate was 77.2% with intention to treat analysis (ITT). Conclusions: In conclusion, this study suggested that G/P therapy in Turkey is used in real life with very high efficacy and tolerability. In addition, a significant change was observed in the genotype distribution previously reported in Turkey in the patient group we treated.
