May 31, 2016 updated by: AbbVie (prior sponsor, Abbott)

An Open-Label, Sequential Arm, Multicenter Study to Evaluate the Antiviral Activity, Safety and Pharmacokinetics of ABT-450 With Ritonavir (ABT-450/r) Dosed in Combination With ABT-267 With and Without Ribavirin (RBV) in Treatment-Naïve Subjects With Genotype 1, 2 or 3 Chronic Hepatitis C Virus (HCV) Infection

The purpose of this study was to evaluate the efficacy, safety and pharmacokinetics of ABT-450/r when given together with ABT-267 and with and without RBV in treatment-naïve participants with genotype 1, 2 or 3 chronic HCV infection.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This was a 2 sequential arm, combination treatment study where each arm contained 3 cohorts: one each for HCV genotype 1, 2, and 3. The study consisted of 2 phases, a treatment phase and a post-treatment phase. The treatment phase was designed to explore the antiviral activity, safety and pharmacokinetics of ABT-450/r dosed in combination with ABT-267 with and without RBV for up to 12 weeks. The post-treatment phase was designed to monitor and evaluate Sustained Virologic Response (SVR) 12, SVR 24, and the evolution and persistence of viral resistance to ABT-267 and ABT-450 in HCV genotype 1-, 2-, and 3-infected participants who have been exposed to ABT-267 and ABT-450/r. Arms 1 and 2 were enrolled sequentially.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Suppressed Below the Lower Limit of Quantitation (LLOQ) From Week 4 Through Week 12 [(Extended Rapid Virologic Response (eRVR)]
Time Frame: Week 4 through Week 12
Analysis of the percentage of participants with hepatitis C virus ribonucleic acid less than the lower limit of quantitation (< 25 IU/mL). Participants with missing data were imputed as failures.
Week 4 through Week 12

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Sustained Virologic Response 12 Weeks (SVR12) Post-treatment
Time Frame: Post-treatment Day 1 to Post-treatment Week 12
Sustained Virologic Response 12 (SVR12) is defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) less than the lower limit of quantification (< LLOQ; < 25 IU/mL) 12 weeks after the last dose of study drug. Participants with missing data were imputed as failures.
Post-treatment Day 1 to Post-treatment Week 12
Percentage of Participants With Sustained Virologic Response 24 Weeks (SVR24) Post-Treatment
Time Frame: Post-treatment Day 1 to Post-treatment Week 24
Sustained Virologic Response 24 (SVR24) is defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) less than the lower limit of quantification (LLOQ; < 25 IU/mL) 24 weeks after the last dose of study drug. Participants with missing data were imputed as failures.
Post-treatment Day 1 to Post-treatment Week 24
Percentage of Participants With Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) < 1000 International Units Per Milliliter (IU/mL)
Time Frame: Week 2
Analysis of participants with HCV RNA levels below 1000 IU/mL at Week 2. Participants with missing data were imputed as failures.
Week 2
Percentage of Participants With Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) Below the Lower Limit of Quantitation (LLOQ) at Week 4 Rapid Virologic Response (RVR)
Time Frame: Week 4
Analysis of percentage of participants with hepatitis C virus ribonucleic acid less than the lower limit of quantitation (< 25 IU/mL). Participants with missing data were imputed as failures.
Week 4
Percentage of Participants With Virologic Failure During Treatment
Time Frame: Day 1 through Week 12
Virologic failure during treatment is defined as a participant meeting any virologic stopping criteria, including 1) rebound (defined as the first day of 2 consecutive increases of at least 0.5 log10 IU/mL above nadir (local minimum value), or first day of 2 consecutive HCV RNA >= LLOQ for participants who previously achieved HCV RNA < LLOQ) during treatment, 2) participant who fails to suppress (defined as never achieving HCV RNA < LLOQ during treatment).
Day 1 through Week 12
Percentage of Participants Who Experienced Virologic Relapse Through End of Post Treatment Period (up to 48 Weeks)
Time Frame: Post-treatment Day 1 to Post-treatment Week 48
Virologic relapse is defined as confirmed hepatitis C virus (HCV) ribonucleic acid (RNA) >= lower limit of quantitation (LLOQ) (2 consecutive measurements >= LLOQ) at any point in the post-treatment period among participants with HCV RNA < LLOQ at the end of treatment. Participants with missing data were imputed as failures.
Post-treatment Day 1 to Post-treatment Week 48

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
