Trial summary

Anemia is more frequent in patients receiving telaprevir with pegylated-interferon/ribavirin than in those receiving pegylated-interferon/ribavirin alone. The objective was to measure the impact of telaprevir on ribavirin bioavailability and to assess the concomitant renal function. Read more about this study

About this study

Official title: Ribavirin Bioavailability After Telaprevir Exposure in Hepatitis C Patients Treated With PEGylated -Interferon/Ribavirin/Telaprevir Triple Therapy

Anemia is more frequent in patients receiving telaprevir with pegylated-interferon/ribavirin than in those receiving pegylated-interferon/ribavirin alone. The objective was to measure the impact of telaprevir on ribavirin bioavailability and to assess the concomitant renal function.

What is being measured

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

  1. Change in ribavirin plasma trough concentration between baseline and week 4 of triple therapy

    Plasma ribavirin trough concentrations were measured using a validated high-performance liquid chromatography-diode array detector method, a highly specific, sensible, and precise method of quantification

    Measured: before telaprevir initiation during the previous course of PEG (pegylated)-IFN (interferon)/ribavirin combination therapy (T-1), and during the early phase (week 4 ± 2 weeks) of therapy

Secondary outcomes (5)
  1. Change in renal function between baseline and week 4 of triple therapy

    Renal function was assessed with the commonly used Modification of the Diet in Renal Disease (MDRD) study equation which allows to assess the estimated glomerular filtration rate (eGFR).

    Measured: Before telaprevir initiation (T-1), and during the early phase (week 4 ± 2 weeks) of therapy

  2. Ribavirin plasma trough concentration at week 8 of therapy

    Measured: at the later phase of therapy (Week 8 ± 2 weeks)

  3. Ribavirin plasma trough concentration after telaprevir withdrawal

    Measured: after telaprevir cessation (at least 4 weeks after telaprevir withdrawal (Week 16))

  4. Renal function at week 8 of therapy

    Measured: at the later phase of therapy (Week 8 ± 2 weeks)

  5. Renal function after telaprevir withdrawal

    Measured: after telaprevir cessation (at least 4 weeks after telaprevir withdrawal (Week 16))

Questions about this trial

What is this clinical trial studying?

An observational study of Hepatitis C, run by Hospices Civils de Lyon at 1 site in France.

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 3 inclusion and 1 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 29 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. 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.

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?

Change in ribavirin plasma trough concentration between baseline and week 4 of triple therapy (time frame: before telaprevir initiation during the previous course of PEG (pegylated)-IFN (interferon)/ribavirin combination therapy (T-1), and during the early phase (week 4 ± 2 weeks) of therapy). 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 29 Aug 2016.
