AbbVie, a global, research-based biopharmaceutical company, submitted marketing authorization applications (MAAs) to the European Medicines Agency (EMA) seeking approval for the company's investigational, all-oral, interferon-free regimen for the treatment of adult patients with chronic genotype 1 (GT1) hepatitis C virus (HCV) infection. The MAAs are supported by data from the largest all-oral, interferon-free clinical programme in GT1 patients conducted to date, which consists of six phase III studies that include more than 2,300 patients in over 25 countries.

"These regulatory submissions bring us closer to offering adult genotype 1 chronic hepatitis C patients an all-oral, interferon-free regimen which has the potential to provide a promising advancement for the hepatitis C community in the European Union," said Scott Brun, vice president, pharmaceutical development, AbbVie. "This regulatory milestone, on the heels of our submission of a New Drug Application in the US, represents an important step for our pipeline."

The EMA has granted AbbVie's request for accelerated assessment for ABT-450/ritonavir, ombitasvir (ABT-267), and dasabuvir (ABT-333), a designation that is granted to new medicines of major public health interest. Review of AbbVie's MAAs will be conducted under the centralized licensing procedure which, when finalized, provides one marketing authorization in all 28 member states of the European Union (EU). Although accelerated assessment could shorten the EMA's review time by approximately two months, it does not guarantee a positive opinion from the EMA's Committee for Medicinal Products for Human Use (CHMP) or final approval by the European Commission. If approved, ABT-450/ritonavir, ombitasvir (ABT-267), and dasabuvir (ABT-333) could be available for marketing in the EU in the first quarter of 2015.

Globally, approximately 160 million people are chronically infected with hepatitis C2 and an estimated 3 million to 4 million people are newly infected each year. In Europe, approximately 17.5 million people have chronic hepatitis C,4 with GT1 as the predominant genotype.


The AbbVie investigational regimen consists of the fixed-dose combination of ABT-450/ritonavir (150/100mg) co-formulated with ombitasvir (ABT-267) 25mg, dosed once daily, and dasabuvir (ABT-333) 250mg with or without ribavirin (weight-based), dosed twice daily. The combination of three different mechanisms of action interrupts the hepatitis C virus replication process with the goal of optimizing sustained virologic response rates across different patient populations.

The AbbVie HCV clinical development program is intended to advance scientific knowledge and clinical care by investigating an interferon-free, all-oral regimen with and without ribavirin with the goal of producing high sustained virologic response rates in as many patients as possible, including those that typically do not respond well to treatment, such as previous non-responders to interferon-based therapy or patients with advanced liver fibrosis or cirrhosis.

ABT-450 was discovered during the ongoing collaboration between AbbVie and Enanta Pharmaceuticals for hepatitis C virus protease inhibitors and regimens that include protease inhibitors. ABT-450 is being developed by AbbVie for use in combination with AbbVie's other investigational medicines for the treatment of hepatitis C.
