About this study

Official title: Open-Label, Phase 3b Study To Determine Efficacy and Safety of Telaprevir, Pegylated-Interferon-alfa-2a and Ribavirin in Hepatitis C Genotype 1 Infected, Stable Liver Transplant Subjects

The purpose of this study is to evaluate the effectiveness of telaprevir in combination with Peg-IFN-alfa-2a and ribavirin in stable liver transplant patients with chronic hepatitis C virus (HCV) genotype 1.

Read the detailed description

This is an open-label (all people know the identity of the intervention), multicenter study in genotype 1 chronic HCV infected liver transplant patients who will be treated for 12 weeks with telaprevir 750 mg every 8 hours given in combination with Peg-IFN-alfa-2a and ribavirin followed by 36 weeks of treatment with Peg-IFN-alfa-2a and ribavirin alone. The total treatment duration will be 48 weeks. Safety will be evaluated throughout the study and will include evaluations of adverse events, clinical laboratory tests, electrocardiogram, vital signs, and physical examination.

What participants receive

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

  • TelaprevirDrug

    Type=exact number, unit=mg, number=375, form=tablet, route=oral. Patients will receive 2 oral tablets (750 mg) every 8 hours for 12 weeks.

  • Pegylated interferon alfa-2aDrug

    Type=exact number, unit=µg, number=180, form=injection, route=subcutaneous. 180 microgram (µg) per week, subcutaneous injection, for 48 weeks.

  • RibavirinDrug

    Type=exact number, unit=mg, number=200, form=tablet, route=oral. Starting from 600 mg (3 tablets) per day on Day 1. This dose will become higher or lower based on blood results and the investigators opinion (to a goal of 1000 to 1200 mg/day [5 to 6 tablets] based on subject weight), twice daily regimen, for 48 weeks.

  3. Number of patients achieving SVR24 planned(c)

    SVR24 planned(c) is defined as having an undetectable plasma HCV RNA level 24 weeks after the last planned dose of study medication.

    Measured: Week 72

  4. Number of patients having an undetectable HCV RNA level at Week 4 of treatment

    Measured: Week 4

  5. Number of patients having an undetectable HCV RNA level at Week 12 of treatment

    Measured: Week 48

  9. Number of patients having less than 25 IU/mL at the planned end of treatment

    Virologic failure is defined as patients who meet a virologic stopping rule and/or meet the definition of viral breakthrough.

    Measured: Week 48

  11. Number of patients with relapse after undetectable HCV RNA at actual end of treatment

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous undetectable HCV RNA (less than 25 IU/mL, target not detected) at actual end of treatment.

    Measured: Week 48

  12. Number of patients with relapse after undetectable HCV RNA at planned end of treatment

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous undetectable HCV RNA (less than 25 IU/mL, target not detected) at planned end of treatment.

    Measured: Week 48

  13. Number of patients with relapse after previous HCV RNA less than 25 IU/mL at planned end of treatment

    Number of patients who relapse, defined as having confirmed detectable HCV RNA during the follow-up period after previous HCV RNA less than 25 IU/mL at planned end of treatment.

    Measured: Week 48

  14. Number of patients with viral breakthrough

    Number of patients with viral breakthrough (defined as an increase more than 1 log in HCV RNA level from the lowest level reached, or a value of HCV RNA more than 100 IU/mL in patients whose HCV RNA has previously become less than 25 IU/mL during treatment).

    Measured: Week 48

  15. Change from baseline in log HCV RNA values

    Change from baseline in log HCV RNA values at each time point during treatment.

    Measured: Up to Week 52

  16. Number of patients who have changes in liver graft biopsy histology

    Measured: Up to Week 72

  17. Number of patients with adverse events

    Measured: Up to Week 72

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Telaprevir, Pegylated interferon alfa-2a and Ribavirin in people with Chronic Hepatitis C Virus (HCV) Infection, run by Janssen-Cilag International NV at 21 sites in 6 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 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 30 Jun 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in France, Germany, Belgium, Spain, Austria 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Number of patients achieving sustained virologic response (SVR) 12 planned (time frame: Week 60). 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 30 Jun 2016.
