About this study

Official title: A Randomized, Open-lable, Multicenter, Parallel Group Study to Compare SVR Rate of Pegasys Plus Ribavirin for 48 Weeks vs. 36 Weeks in Patients With Chronic Hepatitis C

The purpose of this study is to evaluate the effect of PEGASYS® (peginterferon alfa-2a 40KD) plus Robatrol® (ribavirin) combination therapy given for 36 weeks versus 48 weeks on the clearance of HCV viremia 24 weeks after treatment end

Read the detailed description

Pegylated interferon plus ribavirin brings a good therapeutic response and curability. However, the adverse effects and sufferings are lots. Response-guided, personalized treatment is current principle. In patients of CHC, GT1 PR treatment for 24 weeks is established in rapid virologic responders (RVR) who have low viral load before treatment. As to patients with RVR but high viral load (HVL), the treatment duration is 48 weeks that is the same as patients with complete early virologic response (cEVR). Is a shorter duration of treatment feasible for those with a good virokinetic response? The ideal treatment duration for patients of chronic hepatitis C, GT-1, high viral load with RVR has had no enough data yet. Is it really necessary to double the treatment duration (48 weeks) for patients of chronic hepatitis C, GT-1, high viral load with RVR? Is 36-week adequate for them? A multicenter trial of INDIV-2 was presented at EASL 2010. They treated CHC patients of naïve GT1 HVL and RVR for 30 weeks and got similarly good SVR as those treated for 48 weeks (85% vs. 82%).

Therefore, investigators design a randomized controlled study to investigate the SVR rates between treatment for 36 weeks and for 48 weeks in patients of CHC, GT1, HVL and RVR.

What is being measured

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

  1. Sustained virological response

    Sustained virological response (SVR) defined as percentage of patients with HCV RNA < 15 IU/ML as measured by the Roche COBAS AmpliPrep / COBAS TaqMan® HCV Test at 24 weeks post completion of the 36 or 48 week treatment periods.

    Measured: At 24 weeks after end of treatment

Secondary outcomes (3)
  1. Virological Response Rate at week 2

    Virological Response Rate at week 2 defined as the percentage of patients with HCV RNA < 15 IU/ML as measured by the Roche COBAS AmpliPrep / COBAS TaqMan® HCV at 2 weeks post treatment.

    Measured: At treatment week 2

  2. Virological response at end of treatment

    Virological response at end of treatment defined as the percentage of patients with HCV RNA < 15 IU/ML as measured by the Roche COBAS AmpliPrep / COBAS TaqMan® HCV Test after the last dose of study medication(± 28 days).

    Measured: At end of treatment

  3. Correlation of virological response and SVR rate

    Correlation of virological response (HCV RNA < 15 IU/ML) at week 2 and SVR rate in each group.

    Measured: At 24 weeks after end of treatment

Questions about this trial

What is this clinical trial studying?

A study testing Peginterferon alfa-2a plus Ribavirin in people with Chronic Hepatitis C, run by Chang Gung Memorial Hospital at 7 sites in Taiwan.

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 6 inclusion and 18 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: stopped early, as of the sponsor's last update on 29 Jul 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in 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.

Are results available for this study?

The study was stopped early (reason given: early termination due to difficult collection of patients). Results are not available in the source record.

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?

Sustained virological response (time frame: At 24 weeks after end of treatment). 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 Jul 2015.
