Idenix Announces Positive Clinical Data for HCV Drug Candidates IDX184 and IDX719
Idenix Pharmaceuticals, Inc. (Nasdaq: IDIX) 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.
