CAMBRIDGE, Mass., June 19, 2012 (GLOBE NEWSWIRE) -- Idenix Pharmaceuticals, Inc. (Nasdaq:IDIX), a biopharmaceutical company engaged in the discovery and development of drugs for the treatment of human viral diseases, today announced results from an ongoing phase IIb study of IDX184 in combination with pegylated interferon and ribavirin (PegIFN/RBV). Of the first cohort of 31 patients enrolled in the study, those who achieved an eRVR (n=18), defined as having undetectable levels of virus at 4 weeks and 12 weeks, were randomized to stop treatment after either an additional 12 weeks (n=9) or 36 weeks (n=9) of PegIFN/RBV. Of the nine patients who completed their 12-week PegIFN/RBV extended treatment phase, 100% of patients (4/4) in the 100 mg arm and 80% of patients (4/5) in the 50 mg arm achieved a sustained virologic response four weeks after the completion of treatment (SVR4). Patients who did not achieve an eRVR automatically entered the 36-week PegIFN/RBV extended treatment phase which is ongoing. To date, the side effect profile of IDX184 combined with PegIFN/RBV is consistent with that of PegIFN/RBV alone.
