Sofosbuvir-Based Regimens Well Tolerated in Asian American Patients with HCV

Sofosbuvir for the treatment of hepatitis C specifically in Asian American communities was well-tolerated, according to a new report.

Investigators from NYU School of Medicine identified 186 eligible patients from across 11 sites in the United States and enrolled them in their study in order to evaluate sofosbuvir-based regimens in a cohort of Asian Americans. The study authors said that there is only limited data about treatment outcomes in Asian Americans with hepatitis C.

The study period lasted from December 2013 through June 2017 and the investigators measured sustained virologic response rates at 12 and 24 weeks post-treatment. The study authors also examined secondary endpoints of safety by tolerability and adverse events.

At the start of the study, 31% of the patients were cirrhotic, or 57 of 186. Another third of the group was treatment experienced, the study authors wrote. The medication adherence assessments were based on patient’s self-reports, they said, which could mean they were underestimated.

Many of the subjects (42%) received ledispavir/ sofosbuvir combination therapy. The overall sustained virologic response was 95%, the study authors said, with a range from 86% in genotype 1b on sofosbuvir plus ribavirin to 100 in genotype 1b in patients on the ledipasvir plus sofosbuvir in the subgroup analysis.

The sustained virologic response was significantly lower, the study authors wrote, in cirrhotic than non-cirrhotic patients (88% vs. 98%, respectively). Cirrhotic patients with treatment failure were primary genotype 1, the study authors said, including genotypes 1a, 1b, as well as one patient with genotype 5.
