About this study

Official title: A Randomized, Open-Label, Multicenter Study to Evaluate the Efficacy and Safety of ABT-493/ABT-530 in Japanese Adults With Chronic Hepatitis C Virus Infection (CERTAIN-1)

Read the detailed description

The study consisted of two sub-studies that enrolled in parallel. Substudy 1 was randomized, open-label, and active-controlled, wherein HCV treatment-naïve or interferon (IFN)-experienced (i.e., DAA treatment-naïve), genotype (GT)1-infected participants without cirrhosis were enrolled. Substudy 2 was non-randomized, open label, and enrolled special populations of HCV-infected participants [GT1- or GT2-infected subjects with compensated cirrhosis, HCV GT3-, 4-, 5- and 6-infected subjects (with compensated cirrhosis or without cirrhosis), HCV GT1- and GT2-infected subjects who had failed prior DAA treatments (with compensated cirrhosis or without cirrhosis), HCV GT1- or GT2-infected subjects with severe renal impairment (with compensated cirrhosis or without cirrhosis)].

What is being measured

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

Percentage of Participants in Arms A and B With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug.
Measured: 12 weeks after the last actual dose of study drug

Secondary outcomes (4)

Percentage of Participants in Arm A With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug. 95% CI was calculated using the normal approximation to the binomial distribution.
Measured: 12 weeks after the last actual dose of study drug
Percentage of Participants for Each Sub-Population in Arms C and D With Sustained Virologic Response 12 Weeks Post-treatment (SVR12)
SVR12 was defined as plasma hepatitis C virus ribonucleic acid (HCV RNA) level less than the lower limit of quantification [<LLOQ]) 12 weeks after the last dose of study drug. Subpopulations defined as Genotype 1 and 2 infected cirrhotic participants, prior direct acting antiviral agent (DAA) treatment experienced (T-exp) participants, Genotype 3, 4, 5 or 6-infected participants, and participants with severe renal impairment (RI). 95% CI was calculated using the Wilson score method.
Measured: 12 weeks after the last actual dose of study drug
Percentage of Participants With On-treatment Virologic Failure
On-treatment virologic failure was defined as confirmed increase of > 1 log(subscript)10(subscript) IU/mL above the lowest value post-baseline HCV RNA during treatment; confirmed HCV RNA ≥ 100 IU/mL after HCV RNA < LLOQ during treatment, or HCV RNA ≥ LLOQ at end of treatment with at least 6 weeks of treatment. 95% CI was calculated using the Wilson score method.
Measured: Treatment Weeks 1, 2, 4, 8 (end of treatment for 8-week treatment arm), and 12 (end of treatment for 12-week treatment arm) or premature discontinuation from treatment
Percentage of Participants With Post-Treatment Relapse
Post-treatment relapse was defined as confirmed HCV RNA ≥ LLOQ between the end of treatment and 12 weeks after the last dose of study drug among participants with HCV RNA levels < LLOQ at the end of treatment, excluding participants who were been shown to be re-infected. The confidence interval was calculated using the Wilson score method.
Measured: From the end of treatment through 12 weeks after the last dose of study drug

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing ABT-493/ABT-530 and OBV/PTV/r in people with Chronic Hepatitis C Virus and Hepatitis C Virus, 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 8 inclusion and 7 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 16 Jul 2021. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 23 Jul 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 in Arms A and B With Sustained Virologic Response 12 Weeks Post-treatment (SVR12) (time frame: 12 weeks after the last actual 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 NCT02707952, which also lists 6 linked publications.

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 16 Jul 2021.
