Comparative effectiveness of pan-genotypic therapies for the treatment of patients with hepatitis C virus infection in Bulgaria

Abstract

Hepatitis C virus (HCV) is a positive-stranded RNA virus which belongs to the family of Flaviviridae, predominantly infecting liver hepatocytes. HCV infection is a major cause for morbidity worldwide. Aim: The primary objective was to evaluate the comparative effectiveness of pan-genotypic therapies for the treatment of patients with HCV infection in Bulgaria. Materials & methods: The databases MEDLINE, EMBASE, Cochrane Library, PubMed and clinicaltrials.gov were searched to identify studies evaluating the therapeutic efficacy of sofosbuvir/velpatasvir/voxilaprevir, sofosbuvir/velpatasvir and glecaprevir/pibrentasvir for the treatment of HCV patients. Results: The range of sustained virologic response rates among all genotypes achieved after therapy with sofosbuvir/velpatasvir/voxilaprevir was 92–100% (8-week therapy) in treatment-naive patients and 99–100% (12-week therapy) in experienced patients. The range of sustained virologic response rates with glecaprevir/pibrentasvir was 91–100% (12-week therapy) and 97–100% (12-week therapy) with sofosbuvir/velpatasvir. Conclusion: Sofosbuvir/velpatasvir/voxilaprevir is a noninferior therapy offering a simple and short-term treatment regimen with high efficacy, favorable safety profile and good tolerability.
