Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Males and females, ≥ 18 years of age
  • Subjects chronically infected with HCV Genotype (GT)-1b only as documented by positive HCV RNA and anti-HCV antibody at screening and either:
  • Positive anti-HCV antibody, HCV RNA or positive HCV genotype test at least 6 months prior to screening
  • or

Asunaprevir + DaclatasvirExperimentalAsunaprevir 100mg soft capsule by mouth twice daily for 24 weeks and Daclatasvir 60mg tablet by mouth once daily for 24 weeks
Receives: Drug: Asunaprevir; Drug: Daclatasvir

What is being measured

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

  1. Percentage of Participants With Sustained Virologic Response (SVR) at Post-Treatment Follow-up Week 24 (SVR24)

    SVR was defined as Hepatitis C Virus ribonucleic acid (HCV RNA) < lower limit of quantitation (LLOQ) target detected (TD) or not detected (TND) at post-treatment follow-up Week 24.

    Measured: 24 Weeks after treatment discontinuation (Follow-up Week 24)

Secondary outcomes (9)
  1. Percentage of Participants With Sustained Virologic Response (SVR) at Post-Treatment Follow-up Week 12 (SVR12)

    SVR12 was defined as HCV RNA < LLOQ target detected or not detected at post-treatment follow-up Week 12. For SVR12, missing HCV RNA data at follow-up Week 12 was imputed using the Next Value Carried Backwards (NVCB) approach.

    Measured: 12 Weeks after treatment discontinuation (Follow-up Week 12)

  2. Number of Participants With Adverse Events (AEs), Serious AEs (SAEs), Death, and AEs Leading to Discontinuation

    An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. An SAE is an AE resulting in any of the following outcomes or deemed significant for any other reason: death, initial or prolonged inpatient hospitalization, life-threatening experience (immediate risk of dying), persistent or significant disability/incapacity, or a congenital anomaly, or a medically important event.

    Measured: 7 days after treatment discontinuation

  3. Percentage of Participants With SVR24 by the rs12979860 Single Nucleotide Polymorphisms (SNP) in the IL 28B Gene at Post-Treatment Follow-up Week 24

    Participants categorized into three genotypes based on SNPs in the IL28B gene were assessed for SVR24, defined as response in which hepatitis C virus RNA levels below lower limit of quantitation or below target detected or target not detected at follow-up Week 24.

    Measured: 24 Weeks after treatment discontinuation (Follow-up Week 24)

  4. Percentage of Participants With HCV RNA< LLOQ Target Not Detected at the End of Treatment (Week 24)

    Blood was drawn from each participant to assess HCV RNA plasma levels using the Roche COBAS® Taqman quantitative RT-PCR assay, v2.0. The lower and upper limits of quantitation (LOQs) of the assay for HCV GT-1 were 25 IU/mL and 3.91 X10^8 IU/mL, respectively; the limit of detection was ~ 10 IU/mL

    Measured: Week 24 (End-of Treatment)

  5. Number of Participants With Rapid Virologic Response (RVR)

    RVR was defined as HCV RNA < LLOQ, target not detected at treatment Week 4.

    Measured: Treatment Week 4

  6. Percentage of Participants With Complete Early Virologic Response (cEVR)

    cEVR was defined as HCV RNA < LLOQ, target not detected at treatment Week 12.

    Measured: Treatment Week 12

  7. Number of Participants With Extended Rapid Virologic Response (eRVR)

    eRVR was defined as HCV RNA < LLOQ, target not detected at treatment Weeks 4 and 12.

    Measured: Treatment Week 4 and Week 12

  8. Number of Participants With HCV RNA < LLOQ Target Detected or Not Detected at the End of Treatment (Week 24)

    Antiviral efficacy is measured by the number of participants with HCV RNA< LLOQ (lower limit of quantification), TD (target detected) or TND (target not detected) at End of Treatment (Week 24)

    Measured: Week 24 (End-of Treatment)

  9. Number of Participants With Virologic Response (VR) at Treatment Week 4 and 12

    VR was defined as HCV RNA < LLOQ, target detected or not detected at specific time points (Week 4 and Week 12)

    Measured: Treatment Week 4 and 12

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Asunaprevir and Daclatasvir in people with Hepatitis C, run by Bristol-Myers Squibb at 38 sites in 3 countries.

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 15 inclusion and 13 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 11 Aug 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 38 sites in China, South Korea, Taiwan. 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 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 11 Jul 2019). 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 With Sustained Virologic Response (SVR) at Post-Treatment Follow-up Week 24 (SVR24) (time frame: 24 Weeks after treatment discontinuation (Follow-up Week 24)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 11 Aug 2020.
