What is being measured

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

  1. Maximum Plasma Concentration (Cmax) of ABT-267 Following Monotherapy on Day 1

    Blood samples were collected pre-dose (time 0) and at 2, 4, and 6 hours post-dose on Day 1 and pre-dose on Day 2 (ABT-267 monotherapy). The samples were analyzed for ABT-267 using validated analytical methods. Maximum plasma concentration (Cmax; measured in ng/mL) was estimated using noncompartmental analyses.

    Measured: Day 1 (pre-dose [time 0] and at 2, 4, and 6 hours post-dose) and Day 2 (pre-dose)

  2. Time of Maximum Plasma Concentration (Tmax) of ABT-267 Following Monotherapy on Day 1

    Blood samples were collected pre-dose (time 0) and at 2, 4, and 6 hours post-dose on Day 1 and pre-dose on Day 2 (ABT-267 monotherapy). The samples were analyzed for ABT-267 using validated analytical methods. Time of maximum plasma concentration (Tmax; measured in hours) was estimated using noncompartmental analyses.

    Measured: Day 1 (pre-dose [time 0] and at 2, 4, and 6 hours post-dose) and Day 2 (pre-dose)

  3. Area Under the Plasma Concentration-time Curve From Time 0 to 24 Hours (AUC[24]) of ABT-267 Following Monotherapy on Day 1

    Blood samples were collected pre-dose (time 0) and at 2, 4, and 6 hours post-dose on Day 1 and pre-dose on Day 2 (ABT-267 monotherapy). The samples were analyzed for ABT-267 using validated analytical methods. Area under the plasma concentration-time curve from time 0 to 24 hours (AUC[24]; measured in ng multiplied by hour/mL) was estimated using noncompartmental analyses.

    Measured: Day 1 (pre-dose [time 0] and at 2, 4, and 6 hours post-dose) and Day 2 (pre-dose)

  4. Plasma Concentration of ABT-267 Pre-dose (Ctrough) on Day 2 and Day 3

    Blood samples were collected pre-dose on Day 2 (prior to second dose of ABT-267 monotherapy) and pre-dose on Day 3 (prior to first dose of combination therapy). The samples were analyzed for ABT-267 using validated analytical methods. Pre-dose plasma concentrations on Day 2 and Day 3 (Ctrough, measured in ng/mL) are reported.

    Measured: Day 2 (pre-dose) and Day 3 (pre-dose)

  5. Number of Participants With Adverse Events (AEs)

    An adverse event was defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and that did not necessarily have a causal relationship with this treatment.

    The investigator assessed the relationship of each AE to the use of direct-acting antiviral agents (DAAs), and rated the severity of each event as either: Mild: The AE was transient and easily tolerated by the participant; Moderate: The AE caused the participant discomfort and interrupted usual activities; Severe: The AE caused considerable interference with the participant's usual activities and could have been incapacitating or life-threatening.

    A serious adverse event was any event that resulted in death, was life-threatening, resulted in hospitalization or prolongation of hospitalization, resulted in a congenital anomaly or persistent or significant disability or was any other important medical event requiring medical or surgical intervention.

    Measured: All AEs were collected from the time of study drug administration to 30 days after last dose of study drug (16 weeks).

  6. Mean Maximal Decrease From Baseline in Hepatitis C Virus (HCV) Ribonucleic Acid (RNA) During ABT-267 Monotherapy

    The baseline value was the last measurement before the first dose of ABT-267 monotherapy (Day 1). The maximal decrease during monotherapy was the change from baseline to the lowest log10 IU/mL HCV RNA level any time from the first dose of ABT-267 on Day 1 to the last log10 HCV RNA level before the first dose of ABT-267 combination therapy (Study Day 3).

    Measured: Pre-dose on Days 1, 2, and 3

Secondary outcomes (5)
  1. Percentage of Participants With Sustained Virologic Response 12 Weeks and 24 Weeks After Combination Therapy

    The percentage of participants with sustained virologic response (plasma Hepatitis C virus ribonucleic acid [HCV RNA] level less than the lower limit of quantitation [< LLOQ]) 12 and 24 weeks after the last dose of combination study drug. The LLOQ for the assay was 25 IU/mL.

    Measured: 12 and 24 weeks after last dose of combination study drug

  2. Percentage of Participants With Rapid Virologic Response

    The percentage of participants with virologic response (plasma HCV RNA less than the lower limit of quantitation [< LLOQ]) after 4 weeks of combination therapy.

    Measured: 4 weeks

  3. Percentage of Participants With End-of-Treatment Response

    The percentage of participants with virologic response (plasma HCV RNA less than the lower limit of quantitation [< LLOQ]) at the end of combination therapy (12 weeks).

    Measured: 12 weeks

  4. Percentage of Participants With Extended Rapid Virologic Response

    The percentage of participants with virologic response (plasma HCV RNA less than the lower limit of quantitation [< LLOQ]) at Weeks 4 through 12 of combination therapy.

    Measured: Weeks 4 to 12

  5. Mean Change in Viral Load From Baseline to Pre-dose on Day 2 and Day 3 of ABT-267 Monotherapy

    The relationship between ABT-267 dose, ABT-267 concentration, and response was analyzed as the change in viral load (measured as log10 IU/mL) from baseline (pre-dose on Day 1) to pre-dose on Days 2 and 3. Plasma concentrations of ABT-267 pre-dose on Days 2 and 3 are presented above in 4. Primary Outcome: Plasma Concentration of ABT-267 Pre-dose (Ctrough) on Day 2 and Day 3.

    Measured: Predose on Days 1, 2, and 3

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing ABT-267, ABT-450 and ABT-333 in people with Chronic Hepatitis C Infection, run by AbbVie (prior sponsor, Abbott) at 4 sites in United States.

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 5 inclusion and 5 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 2 Jul 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Jan 2015). 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?

Maximum Plasma Concentration (Cmax) of ABT-267 Following Monotherapy on Day 1 (time frame: Day 1 (pre-dose [time 0] and at 2, 4, and 6 hours post-dose) and Day 2 (pre-dose)). The study lists 6 primary outcomes in all. 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 NCT01563536, 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 2 Jul 2018.
