Coblopasvir and sofosbuvir for treatment of chronic hepatitis C virus infection in China: A single-arm, open-label, phase 3 trial
Liver Int 2020 Nov;40(11):2685-2693.PMID:33047868DOI:10.1111/liv.14633.
Background & aim: An affordable, pangenotypic regimen remains as an unmet medical need for chronic hepatitis C patients in China. This single-arm, open-label, multicenter, phase 3 trial evaluated the efficacy and safety of Coblopasvir, a pangenotypic non-structural protein 5A (NS5A) inhibitor, combined with sofosbuvir for treating Chinese patients with chronic hepatitis C virus (HCV) infection. Methods: Treatment-naïve and interferon-experienced adult patients, including those with advanced fibrosis (F3) or compensated cirrhosis (F4), were treated with a universal, combinational regimen of Coblopasvir 60 mg and sofosbuvir 400 mg, once daily, for 12 weeks. The primary efficacy endpoint was sustained virological response at post-treatment week 12 (SVR12). Results: Overall, 371 patients (men, 51%; age, 47 ± 11 years; genotype 1a < 1%, 1b 48%, 2a 26%, 3a 6%, 3b 7% and 6 12%) were enrolled from 19 sites. Fifty-one patients (14%) had F3, 39 patients (11%) had F4 and 39 patients (11%) were interferon experienced. The overall SVR12 was 97% (95% CI, [94%, 98%]) for the full analysis set and was equal to or above 90% for all predefined subsets. Ten patients (3%) experienced virological relapse and two patients did not complete follow-up. No adverse events (AEs) occurred at a frequency ≥5%, and the most often reported AEs (≥1%) were neutropenia and fatigue. The majority of AEs were mild to moderate and transient without specific medical intervention. Conclusions: The universal, pangenotypic combo of Coblopasvir plus sofosbuvir is an efficacious and safe treatment for Chinese patients monoinfected with HCV of genotype 1, 2, 3 and 6, including those with compensated cirrhosis. Lay summary: The regimen of Coblopasvir and sofosbuvir is a safe and effective treatment for Chinese patients with genotype 1, 2, 3 and 6 HCV infection, including those with compensated cirrhosis. Therefore, this regimen would be a novel choice of treatment for this patient population.
Safety and efficacy of Coblopasvir and sofosbuvir in patients with genotypes 1, 2, 3 and 6 HCV infections without or with compensated cirrhosis
J Viral Hepat 2020 Jan;27(1):45-51.PMID:31520460DOI:10.1111/jvh.13208.
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.
