INTRODUCTIONA pan-genotypic and effective treatment regimen for patients with chronic hepatitis C virus (HCV) infection remains an unmet medical need in China. Alfosbuvir is a novel potent HCV NS5B polymerase inhibitor in development for the treatment of chronic HCV infection. We conducted a phase 3 study to evaluate the efficacy and safety of alfosbuvir in combination with daclatasvir in Chinese patients with HCV infection.METHODSAll patients received 600 mg alfosbuvir tablets plus 60 mg daclatasvir tablets once daily for 12 weeks. The primary endpoint was sustained virological response 12 weeks after the end of treatment (SVR12). A follow-up visit was done at week 4 and 12, and those who achieved SVR12 were followed up at post-treatment week 24.RESULTSOf the 326 patients who received at least one dose of the study drug, 320 (98.2% [95% confidence interval (CI): 96.5%-99.5%]) achieved sustained virological response at post-treatment week 12 (SVR12), which was superior to the historical SVR12 rate of 88% (p < 0.0001). The SVR12 rates were similar regardless of most baseline characteristics. The most common adverse event (AE) (≥ 10%) was hypercholesterolemia. Serious adverse events (SAEs) were reported in 25 (7.7%) patients, none of which was judged to be related to the study drug. The majority of AEs were mild to moderate in severity.CONCLUSIONSAlfosbuvir plus daclatasvir for 12 weeks was highly effective and safe in Chinese patients infected with HCV genotype 1, 2, 3, or 6, suggesting that this regimen could be a promising option for HCV treatment in China irrespective of genotype.TRIAL REGISTRATIONClinicalTrial.gov identifier, NCT04070235.

AbstractAlfosbuvir is a novel potent HCV NS5B polymerase inhibitor in development for the treatment of chronic HCV infection. Our previous studies indicated that alfosbuvir monotherapy was well‐tolerated and druggable in healthy subjects and HCV‐infected patients. Here, we evaluate the efficacy and safety of alfosbuvir in combination with daclatasvir in Chinese patients with HCV genotype 1, 2, 3 or 6. In this open‐label study, patients with chronic HCV infection were randomly assigned with a 1:1:1 ratio to receive 12 weeks of daclatasvir 60 mg plus alfosbuvir at a dose of 400, 600 or 800 mg (Cohort A, B or C) daily. Randomization was stratified by HCV genotype and the presence or absence of cirrhosis at screening. The primary endpoint was a sustained virologic response 12 weeks after the end of treatment (SVR12). A total of 124 patients were enrolled in the study, all of whom were available for post‐treatment week 12 assessments. SVR12 was achieved in 92.7% (38/41), 95.2% (40/42) and 100% (41/41) of patients in Cohort A, B and C respectively. The most common adverse events were hepatic steatosis, upper respiratory tract infection, hypercholesterolaemia, hypertriglyceridaemia, blood bilirubin increased, and total bile acids increased. There were no discontinuations due to adverse events, and no treatment‐related serious adverse events were reported. Once‐daily oral administration of alfosbuvir plus daclatasvir were highly effective and safe in Chinese patients infected with HCV genotype 1, 2, 3 or 6, suggesting this regimen could be a promising drug candidate for HCV treatment irrespective of genotype.(ClinicalTrials.gov number, NCT04070235).
