Trial Outcomes & Findings for A Study to Evaluate the Efficacy and Safety of ABT-493/ABT-530 in Adults With Chronic Hepatitis C Virus (HCV) Genotype 2 Infection (NCT NCT02640482)

NCT ID: NCT02640482

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 active study drug. The primary efficacy endpoint was the noninferiority of the percentage of participants who achieved SVR12 in Arm A Double Blind (DB) Active Drug excluding prior sofosbuvir (SOF) + ribavirin (RBV) ± pegylatedinterferon (pegIFN) failures compared with the historical control rate for patients treated with the current standard of care (SOF + RBV for 12 weeks).

PRIMARY outcome

Timeframe: 12 weeks after the last actual dose of active study drug

Population: All randomized participants who received at least one dose of study drug in Arm A DB excluding participants with prior SOF + RBV ± pegIFN failures.

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 active study drug. The primary efficacy endpoint was the noninferiority of the percentage of participants who achieved SVR12 in Arm A Double Blind (DB) Active Drug excluding prior sofosbuvir (SOF) + ribavirin (RBV) ± pegylatedinterferon (pegIFN) failures compared with the historical control rate for patients treated with the current standard of care (SOF + RBV for 12 weeks).

SECONDARY outcome

Timeframe: 12 weeks after the last actual dose of active study drug

Population: All randomized participants who received at least one dose of study drug in Arm A DB excluding participants with prior SOF + RBV ± pegIFN failures.

SVR12 was defined as plasma HCV RNA level \<LLOQ 12 weeks after the last dose of study drug. The secondary efficacy endpoint was the superiority of the percentage of participants who achieved SVR12 in Arm A Double Blind (DB) Active Drug excluding prior SOF + RBV ± pegIFN failures compared with the historical control rate for patients treated with the current standard of care (SOF + RBV for 12 weeks). As pre-specified in the study protocol, the primary outcome measure and the secondary outcome measure are not tested independently from each other. Rather, the two measures are ranked in a fixed sequential testing procedure that only if success was demonstrated for the primary outcome (i.e. non-inferiority test of Arm A SVR12 rate to the standard of care) did we test the first secondary outcome (i.e. superiority test of Arm A SVR12 rate to the standard of care).
