NORTH CHICAGO, Illinois, April 22, 2014 /PRNewswire/ --AbbVie (NYSE: ABBV)
submitted its New Drug Application (NDA) to the U.S. Food and Drug
Administration (FDA) 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 NDA is
supported by data from the largest all-oral, interferon-free clinical program
in GT1 patients conducted to date,(1) with six Phase III studies that included
more than 2,300 patients in over 25 countries.

"This NDA submission is a significant advancement for AbbVie's HCV development
program," said Scott Brun, M.D., vice president, Pharmaceutical Development,
AbbVie. "Based on the robust data that have been generated in our
international Phase III HCV program, we believe our all-oral, interferon-free
regimen holds the potential to be a promising new therapy for patients living
with this chronic infection."

In May of 2013, AbbVie's investigational direct-acting antiviral (DAA) regimen
with and without ribavirin for HCV genotype 1 was designated as a Breakthrough
Therapy by the U.S. FDA. This designation is intended to help expedite the
development of drugs for serious or life-threatening conditions and is based
in part on preliminary clinical evidence demonstrating a drug or regimen may
have substantial improvement on at least one clinically significant endpoint
compared to available therapy.

AbbVie plans to submit applications for regulatory approval of its regimen in
the European Union in early May.

In the U.S., an estimated 3.2 million people are living with HCV and the
infection is most prevalent among those born between 1945 and 1965.(2)

About AbbVie's Investigational HCV Regimen

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 RBV
(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.

AbbVie's HCV Development Program

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

ABT-450 was discovered during the ongoing collaboration between AbbVie and
Enanta Pharmaceuticals (NASDAQ: ENTA) 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.
