Trial Outcomes & Findings for A Study to Evaluate the Efficacy and Safety of ABT-493/ABT-530 in Japanese Adults With Genotype 2 Chronic Hepatitis C Virus Infection (NCT NCT02723084)
NCT ID: NCT02723084
Last Updated: 2021-07-16
Results Overview
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification \[\<LLOQ\]) 12 weeks after the last dose of study drug. The primary efficacy endpoint was non-inferiority of the ABT-493/ABT-530 8-week regimen (Arm A) to the sofosbuvir and ribavirin 12 week regimen (Arm B) in SVR12 using a non-inferiority margin of 10% in the intent-to-treat (ITT) population.
