Phase IIb Aviator study demonstrates high SVR rates against genotype 1 HCV

Results from "Aviator,"  AbbVie's phase IIb clinical trial of its investigational direct-acting antivirals (DAAs) for the treatment of hepatitis C virus (HCV) infection, continue to demonstrate high sustained viral response (SVR) rates against genotype 1 HCV, across patient types. Data show greater than 90 percent SVR were achieved in patients new to treatment and in patients who had previously failed treatment with pegylated interferon and ribavirin (null responders). In addition, similar high SVR rates observed after 12 and 24 weeks of treatment in the Phase IIb trial reinforce the adequacy of the 12-week treatment duration for the investigational interferon-free, triple DAA combination.  The triple-DAA combination is currently being studied in Phase III clinical trials. Results will be featured in the official press conference at the 2013 International Liver Congress^® (ILC) in Amsterdam on Wednesday, April 24 at 11:00 CEST and presented on Thursday, April 25.

"These new results from the Aviator study further demonstrate that this investigational all-oral therapy combination can achieve high sustained viral response after 12 weeks of treatment," said Kris Kowdley , M.D., Director of the Liver Center of Excellence and Director of Research in the Digestive Disease Institute at Virginia Mason Medical, and Clinical Professor of Medicine at the University of Washington in Seattle. "The consistency of high sustained viral response rates that we have seen in clinical trials across populations is encouraging, especially given the proportion of patients with these characteristics who have failed with interferon plus ribavirin treatment."

"AbbVie's clinical development program aims to improve virologic cure rates, including in patients who have historically been harder to treat with current therapies, such as prior null responders. While further studies are required to confirm these findings, we remain encouraged by the high viral response rates and the safety profile we have seen in the Aviator study," said Barry Bernstein , divisional vice president, infectious disease development, AbbVie. "Our Phase III trials are progressing well and we remain focused on bringing an interferon-free treatment option to patients with HCV genotype 1 infection."
