AbbVie has announced that the U.S. Food and Drug Administration (FDA) has accepted its New Drug Application (NDA) and granted priority review for the company's, all-oral, interferon-free, two direct-acting antiviral treatment of ombitasvir, paritaprevir, ritonavir (OBV/PTV/r), with ribavirin (RBV). The NDA is for the treatment of adults with chronic genotype 4 (GT4) hepatitis C virus (HCV) infection.

AbbVie's regimen is the first all-oral, interferon-free therapy being evaluated by the FDA for patients in the United Stateswith chronic GT4 HCV infection. This submission affirms the company's commitment to seeking access to curative* therapy for patients living with chronic HCV infection (*curative is defined as when the virus is no longer detectable in the patient's blood 12 weeks after treatment ends; sustained virologic response [SVR12]). 

The FDA granted priority review to AbbVie for the regimen based in part on data from the PEARL-I study, which was recently published online in The Lancet. The FDA grants priority review designation to investigational therapies that treat a serious condition and, if approved, would provide a significant improvement in safety or effectiveness. This designation shortens the regulatory review period for non-new chemical entity NDAs from the normal 10 months to six months. AbbVie's regimen was also granted a Breakthrough Therapy designation by the FDA on June 30, 2014, a status given to investigational treatments for serious or life-threatening conditions with preliminary clinical evidence that may demonstrate substantial improvement on at least one clinically significant endpoint compared to available therapy.
