FDA Approves AbbVie NDA for Viekira XR for Hepatitis C
FDA has approved an AbbVie NDA for Viekira XR (dasabuvir, ombitasvir, paritaprevir and ritonavir) tablets, a once-daily, extended-release co-formulation of the active ingredients in Viekira PAK for treating patients with chronic genotype 1 (GT1) hepatitis C virus infection, including those with compensated cirrhosis (Child-Pugh A). The company notes the product is not for use in patients with decompensated cirrhosis. The drug can be used without ribavirin in GT1b patients and in combination with twice daily ribavirin in GT1a patients. The approval was based on data from a Phase 3 clinical trial program that demonstrated a 100% sustained virologic response 12 weeks following treatment (SVR12) in GT1b patients with 12 weeks of therapy without ribavirin and 95% SVR12 in GT1a patients when used with ribavirin for 12 or 24 weeks.
