R-7128(Mericitabine) is a selective nucleoside analog inhibitor of the hepatitis C virus (HCV) NS5B RNA-dependent RNA polymerase, with activity across all HCV genotypes.
Mericitabine (RG7128) is a nucleoside polymerase inhibitor (NPI). Patients randomized to mericitabine with HCV RNA <15 IU/mL from week 4 to 22 (extended rapid virologic response; eRVR) stopped all treatment at week 24; all other patients continued Peg-IFNα-2a/RBV to complete 48 weeks of treatment. The primary efficacy endpoint was sustained virologic response (SVR; HCV RNA <15 IU/mL after 24 weeks of treatment-free follow-up). SVR was achieved in 56.8% (95% confidence interval [CI]: 45.9-67.0) of mericitabine-treated patients and 36.5% (95% CI: 27.0-47.1) of placebo-treated patients (Δ = 20.3%; 95% CI 5.5-35.2). SVR rates were higher in mericitabine- than placebo-treated patients when subdivided by IL28B genotype (CC, 77.8% versus 56.0%; non-CC, 44.1% versus 16.2%) and hepatic fibrosis (noncirrhotic, 63.3% versus 41.9%; cirrhotic, 38.1% versus 21.7%). Overall relapse rates were 27.7% and 32.0% in mericitabine- and placebo-treated patients, respectively. No evidence of NS5B S282T-variant virus or phenotypic resistance to mericitabine was observed in the one patient who experienced partial response. No S282T variants were detected in any baseline samples. The safety profile of mericitabine was similar to that of, and fewer patients in the mericitabine than in the placebo group discontinued treatment for safety reasons.
