Background & Aims: Glecaprevir plus pibrentasvir (G/P) is a pangenotypic, once-daily, ribavirin-free direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection. In nine phase II or III clinical trials, G/P therapy achieved rates of sustained virologic response 12 weeks after treatment (SVR12) of 93-100% across all six major HCV genotypes (GTs). An integrated efficacy analysis of 8-and 12-week G/P therapy in patients without cirrhosis with HCV GT 1-6 infection was performed. Methods: Data were pooled from nine phase II and III trials including patients with chronic HCV GT 1-6 infection without cirrhosis who received G/P (300 mg/120 mg) for either 8 or 12 weeks. Patients were treatment naive or treatment experienced with peginterferon, ribavirin, and/or sofosbuvir; all patients infected with HCV GT 3 were treatment naive. Efficacy was evaluated as the SVR12 rate. Results: The analysis included 2,041 patients without cirrhosis. In the intent-to-treat population, 943/965 patients (98%) achieved SVR12 when treated for eight weeks, and 1,060/1,076 patients (99%) achieved SVR12 when treated for 12 weeks; the difference in rates was not significant (p = 0.2). A subgroup analysis demonstrated SVR12 rates > 95% across baseline factors traditionally associated with lower efficacy. G/P was well tolerated, with one DAA-related serious adverse event (< 0.1%); grade 3 laboratory abnormalities were rare. Conclusions: G/P therapy for eight weeks in patients with chronic HCV GT 1-6 infection without cirrhosis achieved an overall SVR12 rate of 98% irrespective of baseline patient or viral characteristics; four additional weeks of treatment did not significantly increase the SVR12 rate, demonstrating that the optimal treatment duration in this population is eight weeks. Lay summary: In this integrated analysis of nine clinical trials, patients with chronic HCV genotype 1-6 infection without cirrhosis were treated for either 8 or 12 weeks with the directacting antiviral regimen glecaprevir/pibrentasvir (G/P). The cure rate was 98% and 99% following 8 and 12 weeks of treatment, respectively; the difference in rates was not significant (p = 0.2), nor was there a significant difference in the cure rates across the two treatment durations on the basis of baseline patient or viral characteristics. These results, along with a favourable safety profile, indicate that G/P is a highly efficacious and well-tolerated pangenotypic eight-week therapy for most patients with chronic HCV infection.
