Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT-267 (ABT-450/r/ABT-267) in Japanese Adults With Subgenotype 1b Chronic Hepatitis C Virus (HCV) Infection (GIFT I)

May 2, 2018 updated by: AbbVie

A Randomized, Double-blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of ABT-450/Ritonavir/ABT-267 (ABT-450/r/ABT-267) in Treatment-Naïve and Treatment-Experienced Japanese Adults With Subgenotype 1b Chronic Hepatitis C Virus (HCV) Infection With and Without Compensated Cirrhosis (GIFT I)

This is a phase 3, double-blinded, multicenter study. The study will consist of 2 substudies: Substudy 1 (SS1) will be double-blinded and enroll non-cirrhotic subjects and Substudy 2 (SS2) will be open label and enroll subjects with compensated cirrhosis.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Non-cirrhotic Treatment-Naïve Participants Who Are Eligible for Interferon (IFN)-Based Therapy and Who Have High Viral Load in the DB Active Treatment Group With a Sustained Virologic Response 12 Weeks Post-treatment
Time Frame: 12 weeks after the last dose of study drug
The percentage noncirrhotic treatment-naïve participants who were eligible for IFN-based therapy and who had high viral load at baseline (HCV RNA ≥ 100,000 IU/mL) in the DB active treatment group with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 weeks after the last dose of active study drug (SVR12). Among noncirrhotic treatment-naïve participants who were eligible for IFN-based therapy and who had high viral load at baseline, superiority of Arm A to a clinically relevant threshold based on historical SVR rate with telaprevir plus pegylated interferon alpha/ribavirin (pegIFN/RBV) in treatment-naïve, non-cirrhotic patients with high viral load; the lower bound of 95% confidence interval (LCB) had to exceed 63% to achieve superiority. The 95% confidence interval was calculated using the normal approximation to the binomial distribution.
12 weeks after the last dose of study drug

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants in the Active Treatment Group With On-treatment Virologic Failure During Treatment
Time Frame: up to 12 weeks

On-treatment virologic failure among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 and all enrolled participants with compensated cirrhosis who received at least one dose of OL ABT-450/r/ABT-267. On-treatment virologic failure is defined as the occurrence of at least one of the following:

  • confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) at any point during treatment after HCV RNA < LLOQ (rebound), or
  • confirmed increase from nadir in HCV RNA (defined as 2 consecutive HCV RNA measurements > 1 log10 IU/mL above nadir) at any time point during treatment (rebound), or
  • HCV RNA ≥ LLOQ persistently during treatment with at least 6 weeks (≥ 36 days) of treatment (failure to suppress).

The 95% confidence interval was calculated using the Wilson's score method.

up to 12 weeks

Time Frame: up to 12 weeks
On-treatment virologic failure among all randomized non-cirrhotic participants who received at least one dose of DB ABT-450/r/ABT-267 in the following subpopulations: noncirrhotic treatment-naïve (T-naïve) participants with a high baseline (BL) viral load (HCV RNA ≥ 100,000 IU/mL) who are eligible for IFN-based therapy (IFN-BT), a low viral load (HCV RNA < 100,000 IU/mL), or who are ineligible for IFN-BT; noncirrhotic treatment-experienced (T-exp) participants who relapsed after prior IFN-BT, who were nonresponders to prior IFN-BT, or who were intolerant to IFN-BT. On-treatment virologic failure is defined in Outcome measure 2. The 95% confidence interval was calculated using the Wilson's score method.
up to 12 weeks

Relapse was defined as confirmed HCV RNA ≥ LLOQ (defined as 2 consecutive HCV RNA measurements ≥ LLOQ) between the final treatment visit and 12 weeks after the last dose of study drugs among participants completing treatment and with HCV RNA < LLOQ at the final treatment visit and at least one post-treatment HCV RNA value. The 95% confidence interval was calculated using the Wilson's score method.
