Enanta Pharmaceuticals, Inc., (NASDAQ: ENTA), a research and development-focused biotechnology company dedicated to creating small molecule drugs in the infectious disease field, announced today that new Phase 2b data related to ABT-450, Enanta's lead HCV protease inhibitor identified in its ongoing collaboration with AbbVie, as well as new preclinical data on Enanta's proprietary cyclophilin inhibitor, EDP-546, will be presented at the International Liver Congress, (ILC), which is the 48th Annual Meeting of the European Association for the Study of the Liver (EASL) taking place in Amsterdam April 24-28, 2013.
“Safety and Efficacy of Interferon-Free Regimens of ABT-450/r, ABT-267, ABT-333 ± ribavirin in Patients with Chronic HCV GT1 Infection: Results from the Aviator Study”
Results from "Aviator," AbbVie's Phase 2b clinical trial of ABT-450 combined with two of AbbVie's proprietary 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. SVR rates of 96% to 99% after 12 weeks of treatment were achieved in patients new to treatment (naïve) and 93% in patients who had previously failed treatment with pegylated interferon and ribavirin (null responders). In addition, similarly high SVR rates over 90% observed after 24 weeks of treatment in the Phase 2b 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 3 clinical trials. Data from the "Aviator" study will be presented during the official ILC press conference in Amsterdam on Wednesday, April 24 at 11:00 am CEST and also in an oral presentation on Thursday, April 25.
