A simple, pangenotypic and effective treatment regimen for patients with a broad range of chronic hepatitis C virus (HCV) infections remains an unmet medical need. We conducted a phase 2, randomized, open study involving untreated patients with chronic HCV genotypes 1, 2, 3, or 6 infections. Patients without cirrhosis were randomly assigned in a 1:2 ratio to receive capsules of the NS5A inhibitor coblopasvir at a dose of 30 or 60 mg plus tablets of the nucleotide polymerase inhibitor sofosbuvir (400 mg) once daily for 12 weeks. Patients with cirrhosis received 60 mg coblopasvir plus sofosbuvir for 12 weeks. The primary endpoint was the sustained virologic response at 12 weeks after the end of therapy (SVR12). Of the 110 patients who were enrolled in the study, 59 were male, 62.7% had HCV genotype 1, 24.5% had genotype 2, 6.4% had genotype 3, and 6.4% had genotype 6. The average age was 45.5 years. A total of 10.9% of patients had compensated cirrhosis. The rate of SVR12 was 98.2% in the intention‐to‐treat (ITT). One genotype 6 patient with cirrhosis experienced virologic relapse. One genotype 2 patient without cirrhosis failed to complete the follow‐up and quit the study. Serious adverse events (SAEs) were reported in 2 patients and were not related to coblopasvir and sofosbuvir. Most adverse events (AEs) did not require treatment. Coblopasvir plus sofosbuvir taken once daily for 12 weeks provided high rates of sustained virologic response (SVR) and had a good safety profile among patients with HCV genotypes 1, 2, 3, or 6 infections, including those with compensated cirrhosis.
