Overview
Brief Summary
The purpose of this study was to evaluate the effect of treatment with ABT-450 co-formulated with ritonavir and ABT-267 (ABT-450/r/ABT-267) and ABT-333; 3-DAA regimen, with or without ribavirin (RBV) in adults with chronic hepatitis C virus genotype 1 (HCV GT1) infection.
Detailed Description
This study (TOPAZ-I; M14-423), was a Phase 3b, open-label, multicenter study conducted outside of the United States which, together with its companion study TOPAZ-II (M14-222; NCT 02167945) conducted in the United States, was designed with the primary objective of assessing the effect of treatment response on long-term clinical outcomes in adults with chronic HCV GT1 infection with or without compensated cirrhosis, who were either treatment-naïve or interferon/ribavirin (IFN/RBV) treatment- experienced. In both studies, participants were treated with the 3-DAA regimen with or without RBV. This study consisted of a screening period of up to 42 days, a treatment period of either 12 weeks for HCV GT1a-infected subjects without cirrhosis and for HCV GT1b-infected subjects without cirrhosis or with compensated cirrhosis or 24 weeks for GT1a-infected participants with compensated cirrhosis, and a 260-week post-treatment period.

Outcomes
Primary Outcomes
Hepatocellular Carcinoma: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to hepatocellular carcinoma (HCC) was defined as number of days from 1st day of study drug dosing for subject to date of hepatocellular carcinoma. All HCC was to be included, whether it occurred while subject was still taking study drug or had previously discontinued study drug. If the subject didn't experience the event of interest nor had died (all-cause death), their data was to be censored at the date of their last available assessment. For those with no post-baseline assessment, their data was to be censored on the 1st day of study drug dosing. All-cause death was a censoring event for HCC. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. The pre-specified analysis of hepatocellular carcinoma included pooled data from TOPAZ-I (this study) and the companion study TOPAZ-II (M14-222; NCT02167945).
Liver Decompensation: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to liver decompensation was defined as number of days from the 1st day of study drug dosing for the participant to the date of liver decompensation. All liver decompensation was to be included, regardless of whether it occurred while the participant was still taking study drug or had previously discontinued study drug. If the participant didn't experience the event of interest nor had died (all-cause death), their data was to be censored at the date of their last available assessment of clinical outcomes. For participants with no post-baseline assessment, their data was to be censored on the 1st day of study drug dosing. All-cause death was a censoring event for liver decompensation. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. The pre-specified analysis of liver decompensation included pooled data from TOPAZ-I (this study) and the companion study TOPAZ-II (M14-222; NCT02167945).
Liver-Related Death: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to liver-related death was defined as days from the 1st day of study drug dosing for the subject to date of liver-related death. All liver-related deaths were to be included, regardless of whether the death occurred while subject was still taking study drug or had previously discontinued study drug. If the subject didn't experience event of interest nor had died (all-cause death), their data was to be censored at date of last available assessment. For those with no post-baseline assessment, data was to be censored on 1st day of study drug dosing. All-cause death was a censoring event for liver-related death. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. The pre-specified analysis of liver-related death included pooled data from TOPAZ-I (this study) and the companion study TOPAZ-II (M14-222; NCT02167945).
Liver Transplantation: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to liver transplantation was defined as days from 1st day of study drug dosing for subject to date of liver transplantation. All liver transplantation was to be included, whether it occurred while the subject was still taking study drug or had previously discontinued study drug. If the subject didn't experience event of interest nor had died (all-cause death), their data was to be censored at the date of their last available assessment. For those with no post-baseline assessment, data was to be censored on 1st day of study drug dosing. All-cause death was a censoring event for liver transplantation. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. The pre-specified analysis of liver transplantation included pooled data from TOPAZ-I (this study) and the companion study TOPAZ-II (M14-222; NCT02167945).
All-Cause Death: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to all-cause death was defined as the number of days from the first day of study drug dosing for the participant to the date of death. All deaths were to be included, regardless of whether the death occurred while the participant was still taking study drug or had previously discontinued study drug. If the participant did not die, their data was to be censored at the date of their last available assessment of clinical outcomes. For participants with no post-baseline assessment, the participant's data was to be censored on the first day of study drug dosing. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. The pre-specified analysis of all-cause death included pooled data from TOPAZ-I (this study) and the companion study TOPAZ-II (M14-222; NCT02167945).
All-Cause Death, Liver-Related Death, Liver Decompensation, Liver Transplantation, Hepatocellular Carcinoma: Time to Event
Time Frame: At Post-Treatment Weeks 52, 104, 156, 208, and 260
Time to the composite of clinical outcomes is the time to the first occurrence of all-cause death, liver-related death, liver decompensation, liver transplantation, or hepatocellular carcinoma. All first occurrences were to be included, regardless of whether it occurred while the participant was still taking study drug or had previously discontinued study drug. If the participant did not experience any of these events, their data was to be censored at the date of their last available assessment of clinical outcomes. For participants with no post-baseline assessment, the participant's data was to be censored on the first day of study drug dosing. The event-free survival rates were estimated using Kaplan-Meier methodology and incidence estimates are presented with 95% confidence intervals. Pre-specified analysis included pooled data from this study and from TOPAZ-II; NCT02167945.
