SVR12 data from OMEGA-1, a global open-label Phase 2b study of the efficacy and safety of JNJ-4178 in non-cirrhotic patients with HCV genotypes 1, 2, 4, 5 and 6, were presented at the conference by Dr. Stefan Zeuzem, Professor of Medicine and Chief of the Department of Medicine I at the Goethe University Hospital, Frankfurt, Germany.

The results showed that 98.9% (181/183) of patients treated with JNJ-4178 for 6 weeks achieved SVR12, while 97.8% (178/182) of patients treated with JNJ-4178 for 8 weeks achieved SVR12, with both arms meeting the pre-specified endpoint of statistical non-inferiority compared to historic controls. The triple combination was generally well-tolerated in both arms of the study, with the most frequent adverse events being headache and fatigue. Further information on the study can be found at www.clinicaltrials.gov (NCT02765490).
