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 12 Weeks After Discontinuation of Therapy (SVR12)

    SVR12 was defined as HCV RNA < the lower limit of quantitation (LLOQ; ie, 15 IU/mL) 12 weeks after stopping the study treatment.

    Measured: Posttreatment Week 12

  2. Percentage of Participants Who Permanently Discontinued the Study Drug Due to an Adverse Event

    Measured: First dose date up to Week 12

Secondary outcomes (13)
  1. Percentage of Participants With Sustained Virologic Response 4 Weeks After Discontinuation of Therapy (SVR4)

    SVR4 was defined as HCV RNA < LLOQ 4 weeks after stopping study treatment.

    Measured: Posttreatment Week 4

  2. Percentage of Participants With Sustained Virologic Response 24 Weeks After Discontinuation of Therapy (SVR24)

    SVR24 was defined as HCV RNA < LLOQ 24 weeks after stopping study treatment.

    Measured: Posttreatment Week 24

  3. Change From Baseline in HCV RNA

    Measured: Baseline; Weeks 2, 4, 6, 8, and 12

  4. Percentage of Participants With HCV RNA < LLOQ on Treatment

    Measured: Weeks 2, 4, 6, 8, and 12

  5. Percentage of Participants With Virologic Failure

    Virologic failure was defined as:

    • On-treatment virologic failure:
    • Breakthrough (confirmed HCV RNA ≥ LLOQ after having previously had HCV RNA < LLOQ while on treatment), or
    • Rebound (confirmed > 1 log10 IU/mL increase in HCV RNA from nadir while on treatment), or
    • Non-response (HCV RNA persistently ≥ LLOQ through 8 weeks of treatment)
    • Virologic relapse:
    • Confirmed HCV RNA ≥ LLOQ during the posttreatment period having achieved HCV RNA < LLOQ at last on-treatment visit

    Measured: Baseline to Posttreatment Week 24

  6. Number of Participants Who Develop Viral Resistance (as Assessed by Presence of HCV NS5A and NS5B Genes) to SOF and VEL During Treatment and After Discontinuation of Treatment

    Baseline deep sequencing of the HCV NS5A and NS5B genes was performed for all participants. For all participants with virologic failure, deep sequencing was performed at the first time point after virologic failure if the plasma or serum sample was available and HCV RNA was > 1000 IU/mL.

    Measured: First dose date up to Posttreatment Week 24

  7. Pharmacokinetic (PK) Parameter: AUCtau of SOF

    AUCtau is defined as the population PK derived area under the concentration versus time curve of the drug over the dosing interval.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  8. PK Parameter: AUCtau of GS-331007 (Metabolite of SOF)

    AUCtau is defined as the population PK derived area under the concentration versus time curve of the drug over the dosing interval.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  9. PK Parameter: AUCtau of VEL

    AUCtau is defined as the population PK derived area under the concentration verses time curve of the drug over the dosing interval.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  10. PK Parameter: Cmax of SOF

    Cmax is defined as the population PK derived maximum concentration of the drug.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  11. PK Parameter: Cmax of GS-331007 (Metabolite of SOF)

    Cmax is defined as the population PK derived maximum concentration of the drug.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  12. PK Parameter: Cmax of VEL

    Cmax is defined as the population PK derived maximum concentration of the drug.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

  13. PK Parameter: Ctau of VEL

    Ctau is defined as the population PK derived concentration of the drug at the end of a 24 hour dosing interval. The 24 hour Ctau is estimated based on the combination of sparse PK samples collected at random times across the dosing interval as well as intensive PK samples collected for up to 12 hours post-dose.

    Measured: Sparse PK samples at Weeks 6, 8, and 12 (all participants). Intensive PK samples at predose, 0.25, 0.5, 1, 2, 4, 6, 8, 10, and 12 hours postdose once at Week 6, 8, or 12 (participants who enrolled in the optional PK substudy (N=1))

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 2 inclusion and 0 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 6 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 22 sites in United Kingdom, Canada, Spain, Israel, Australia and 1 more country. 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 12 Nov 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 12 Weeks After Discontinuation of Therapy (SVR12) (time frame: Posttreatment Week 12). The study lists 2 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 NCT03036852, which also lists 2 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 6 Mar 2020.
