About this study

Official title: Real World Evidence of the Effectiveness of Paritaprevir/r - Ombitasvir, ± Dasabuvir, ± Ribavirin in Patients With Chronic Hepatitis C -An Observational Study in Kuwait

The interferon-free combination regimen of paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± ribavirin (RBV) for the treatment of chronic hepatitis C (CHC) has been shown to be safe and effective in randomized controlled clinical trials with strict inclusion and exclusion criteria under well controlled conditions.

This observational study is the first effectiveness research examining the ABBVIE REGIMEN ± RBV, used according to local label, under real world conditions in Kuwait in a clinical practice patient population.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02798315
Study groupRoleWhat they receive
Participants With Hepatitis C Virus (HCV) Genotype 1 or 4Participants with HCV genotype 1 or 4 receiving paritaprevir/r - ombitasvir with or without dasabuvir (ABBVIE REGIMEN) ± RBV. The prescription of a treatment regimen is at the discretion of the physician in accordance with local clinical practice and label, is made independently from this observational study and precedes the decision to offer the patient the opportunity to participate in this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants Achieving Sustained Virological Response 12 Weeks Post-treatment (SVR12)

    SVR12 defined as the HCV ribonucleic acid (RNA) level less than 50 IU/mL 12 weeks after the last dose of study drug

    Measured: 12 weeks (i.e. at least 70 days) after the last dose of study drug

Secondary outcomes (10)
  1. Percentage of Participants With Virological Response at End of Treatment (EoT)

    Virological response defined as HCV RNA level less than 50 IU/mL.

    Measured: Up to EoT, maximum of 24 weeks

  2. Percentage of Participants With Relapse at EoT

    Relapse defined as HCV RNA less than 50 IU/mL at EoT followed by HCV RNA greater than or equal to 50 IU/mL.

    Measured: Up to EoT, maximum of 24 weeks

  3. Percentage of Participants With Breakthrough.

    Breakthrough defined as at least 1 documented HCV RNA less than 50 IU/mL followed by HCV RNA greater than or equal to 50 IU/mL during treatment.

    Measured: Up to EoT, maximum of 24 weeks

  4. Percentage of Participants Meeting the SVR Non-response Categories of On-treatment Virologic Failure or Relapse

    On-treatment virologic failure defined as breakthrough (at least 1 documented HCV RNA less than 50 IU/mL followed by HCV RNA greater than or equal to 50 IU/mL during treatment) or failure to suppress (each measured on-treatment HCV RNA value greater than or equal to 50 IU/mL). Relapse (defined as HCV RNA <50 IU/mL at EoT or at the last on-treatment HCV RNA measurement followed by HCV RNA ≥50 IU/mL post-treatment).

    Measured: 12 weeks (i.e. at least 70 days) after the last dose of study drug

  5. Percentage of Participants Meeting the SVR Non-response Categories of Premature Study Drug Discontinuation or Missing SVR12 Data and/or None of the Above Criteria

    Premature study drug discontinuation category is defined as participants who prematurely discontinued study drug and who experienced no on-treatment virologic failure. The final SVR non-response category was defined as missing SVR12 data and/or none of the above criteria.

    Measured: 12 weeks (i.e. at least 70 days) after the last dose of study drug

  6. Adherence to ABBVIE Regimen: Percentage of the Direct-acting Antiviral (DAA) Dose Taken in Relation to the Target Dose of DAA

    Percentage of the DAA dose taken in relation to the target dose of DAA (cumulative dose taken divided by target dose in percent), presented as the number of participants taking > 95% to ≤ 105% of the target dose and those taking > 80% to ≤ 95% of the target dose.

    Measured: Up to 48 weeks

  7. Adherence to RBV: Percentage of RBV Dose Taken in Relation to the Target Dose of RBV

    Percentage of the RBV dose taken in relation to the target dose of RBV (cumulative dose taken divided by target dose in percent), presented as the number of participants taking > 95% to ≤ 105% of the target dose and those taking > 80% to ≤ 95% of the target dose.

    Measured: Up to 48 weeks

  8. Adherence: Percentage of Planned Duration of RBV Taken by Participant

    Measured: Up to 48 weeks

  9. Change From Baseline in the PAM-13 Questionnaire

    The PAM-13 item scale is a measure used to assess the patient knowledge, skill, and confidence for self-management. Each of the 13 items can be answered with one of four possible response options, which are "disagree strongly" (1), "disagree" (2), "agree" (3), "agree strongly" (4). Based on responses to the 13-item measure, the score is calculated by adding up the raw scores (range of the sum: 13 - 52) and mapping up the value onto a scale of 0-100 indicating strength of agreement with the 13 items. A higher score indicates that the patient is likely to participate more actively in health care processes and takes more responsibility for his or her health.

    Measured: Up to 48 weeks

  10. Patient Support Program (PSP) Questionnaire: Utilization of PSP Components

    Percentage of participants using each component of the PSP, including personal support, educational and information material (printed, online) and additional digital and mobile resources (web-portal, app, and reminders).

    Measured: Up to EoT, maximum of 24 weeks

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Hepatitis C, run by AbbVie.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 31 Dec 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants Achieving Sustained Virological Response 12 Weeks Post-treatment (SVR12) (time frame: 12 weeks (i.e. at least 70 days) after the last dose of study drug). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02798315, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Dec 2018.
