About this study

Official title: Safety and Tolerability of Ribavirin (RO 20-9963) in Combination With Peginterferon Alfa-2a (40 kD)in Patients With Chronic Hepatitis C

This single arm study will evaluate the safety and tolerability of ribavirin in combination with PEGASYS in patients with chronic hepatitis C. Patients will receive ribavirin 800mg, or 1000-1200mg po daily, according to HCV genotype and body weight (< and >75kg)in combination with PEGASYS 180micrograms sc weekly. The anticipated time on study treatment is 3-12 months, and the target sample size is >500 individuals.

What is being measured

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

  1. Number of Participants With Non-Serious Adverse Events (AEs) And Serious Adverse Events (SAEs)

    An AE was any untoward medical occurrence in a participant who received study drug. An SAE was 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; congenital anomaly. Number of participants with non-serious AEs were exclusive of serious AEs.

    Measured: From signing of informed consent up to end of study (up to Week 72)

Secondary outcomes (3)
  1. Percentage of Participants With Sustained Virological Response (SVR) at 24 Weeks After End of Therapy

    SVR at 24 weeks after end of therapy was defined as a negative result of HCV Ribonucleic Acid (HCV RNA) qualitative assay 24 weeks after end of therapy. Percentage of participants with SVR was calculated as [number of participants with negative results of HCV RNA qualitative assay 24 weeks after end of therapy divided by the total number of participants analyzed] multiplied by 100. The participants who failed to undergo tests at 24 weeks after completion of therapy were considered not amenable to therapy.

    Measured: 24 weeks after end of therapy (Week 72)

  2. Percentage of Participants With Undetectable HCV RNA at Weeks 12, 24 and 48 After Therapy Initiation

    HCV RNA levels of < 50 International Units per milliliter (IU/mL) were defined as undetectable HCV RNA. The percentage of participants with undetectable HCV RNA was calculated as [number of participants with undetectable HCV RNA divided by the total number of participants analyzed] multiplied by 100 for Weeks 12, 24 and 48.

    Measured: Weeks 12,24 and 48 After Therapy Initiation

  3. Percentage of Participants With Change in Hemoglobin Level

    Change in hemoglobin level (compared to baseline) was reported as "significant decrease", "Normal" (no change), "Increase", "Decrease", and "Missing". Significant decrease was defined as per Investigator's discretion.

    Measured: Baseline, Weeks 2, 4, 8, 12, 24, 36, 48 and follow-up Weeks 4 (Week 52), 12 (Week 60), and 24 (Week 72)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing peginterferon alfa-2a [Pegasys] and ribavirin in people with Hepatitis C, Chronic, run by Hoffmann-La Roche at 93 sites in Russia.

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 4 inclusion and 4 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 20 Jan 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 93 sites in Russia. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 20 Jan 2016). 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?

Number of Participants With Non-Serious Adverse Events (AEs) And Serious Adverse Events (SAEs) (time frame: From signing of informed consent up to end of study (up to Week 72)). 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 20 Jan 2016.
