Brief Summary:
The purpose of this study was to evaluate the safety and efficacy of ombitasvir/ paritaprevir/ ritonavir and dasabuvir in adults with genotype 1b chronic hepatitis C virus (HCV) infection and cirrhosis.

Condition or disease Intervention/treatment Phase
Chronic Hepatitis C Infection Compensated Cirrhosis Drug: Ombitasvir/Paritaprevir/Ritonavir Drug: Dasabuvir Phase 3

Detailed Description:
This was a multicenter study evaluating the efficacy and safety of ombitasvir/ paritaprevir/ritonavir and dasabuvir administered for 12 weeks in HCV genotype 1b (GT1b)-infected, treatment-naïve and previous pegylated interferon (pegIFN)/ ribavirin (RBV) treatment-experienced adults with compensated cirrhosis. The duration of the study was up to 36 weeks (not including a screening period of up to 42 days) and consisted of a 12-week Treatment Period and a 24-week Post-Treatment Period for all participants who received study drugs.

Arm Intervention/treatment
Experimental: Ombitasvir/Paritaprevir/Ritonavir plus Dasabuvir
Ombitasvir/Paritaprevir/Ritonavir (25/150/100 mg once daily) and Dasabuvir (250 mg twice daily) administered for 12 weeks
Drug: Ombitasvir/Paritaprevir/Ritonavir
Tablet; paritaprevir co-formulated with ritonavir and ombitasvir
Other Names:
  • ABT-267 also known as ombitasvir
  • ABT-450 also known as paritaprevir
  • Ritonavir also known as norvir

Drug: Dasabuvir
Tablet
Other Name: ABT-333




Primary Outcome Measures :
  1. 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.

    The primary efficacy endpoints were non-inferiority and superiority of the percentage of participants who achieved sustained virologic response 12 weeks after treatment in each treatment arm compared with the historical threshold for sofosbuvir and peginterferon (pegIFN)/RBV for the treatment of subjects with HCV GT1b infection and cirrhosis.



Secondary Outcome Measures :
  1. Percentage of Participants With On-Treatment Virologic Failure [ Time Frame: Day 1 through Week 12 ]
    On-Treatment Virologic Failure is defined as confirmed HCV RNA >= LLOQ after HCV RNA < LLOQ during treatment, or confirmed increase from nadir (local minimum value) in HCV RNA [2 consecutive HCV RNA measurements > 1 log10 IU/mL above nadir] at any time point during treatment, or failure to suppress during treatment [all on-treatment values of HCV RNA >= LLOQ] with at least 6 weeks [defined as active study drug duration ≥ 36 days] of treatment.

  2. Percentage of Participants With Post-Treatment Relapse [ Time Frame: Post-treatment Day 1 to Post-treatment Week 12 ]
    Post- Treatment Relapse is defined as confirmed HCV RNA >= LLOQ between end of treatment and 12 weeks after last actual dose of active study drug [up to and including the SVR12 assessment time point] for a participant with HCV RNA < LLOQ at Final Treatment Visit who completes treatment.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Chronic HCV genotype 1-infection prior to study enrollment. Chronic HCV-infection is defined as the following:

    • Positive for anti-HCV antibody (Ab) or HCV RNA > 1,000 IU/mL at least 6 months before Screening, and positive for HCV RNA and anti-HCV Ab at the time of Screening; or
    • HCV RNA > 1,000 IU/mL at the time of Screening with a liver biopsy consistent with chronic HCV-infection (or a liver biopsy performed prior to enrollment with evidence of chronic hepatitis C disease).
  2. Screening laboratory result indicating HCV genotype 1b-infection.
  3. Compensated cirrhosis defined as a Child-Pugh Score of 5 or 6 at Screening.

Exclusion Criteria:

  1. Women who are pregnant or breastfeeding.
  2. Positive test result for Hepatitis B surface antigen (HBsAg) or positive human immunodeficiency virus (HIV) antibody (confirmed by Western Blot).
  3. Any current or past clinical evidence of Child-Pugh B or C classification or clinical history of liver decompensation such as ascites (noted on physical exam), variceal bleeding, or hepatic encephalopathy.
  4. Confirmed presence of hepatocellular carcinoma indicated on imaging techniques such as computed tomography (CT) scan or magnetic resonance imaging (MRI) within 3 months prior to Screening or on an ultrasound performed at Screening (a positive ultrasound result will be confirmed with CT scan or MRI.)
  5. Use of contraindicated medications within 2 weeks of dosing
  6. Screening laboratory analyses showing any of the following abnormal laboratory results:

    • Calculated creatinine clearance (using Cockcroft-Gault method) < 30 mL/min
    • Albumin < 2.8 g/dL
    • International normalized ratio (INR) > 1.8. Participants with a known inherited blood disorder and INR > 1.8 may be enrolled with permission of the AbbVie Study Designated Physician.
    • Hemoglobin < 10 g/dL
    • Platelets < 25,000 cells per mm3
    • Total bilirubin > 3.0 mg/dL
