Trial summary

Pegylated interferon in combination with ribavirin is the current standard treatment of chronic hepatitis C virus infection, but is expensive and has several adverse effects. To modify this standard treatment by optimizing its therapeutic effect and decreasing its adverse events are important. Read more about this study

About this study

Official title: An Open-label, Multi-center, Randomized Study Comparing the Effects of Oral Hypoglycemic Agents on Viral Kinetics of Chronic Hepatitis C Patients Receiving Pegylated Interferon Alfa 2b Plus Ribavirin

Pegylated interferon in combination with ribavirin is the current standard treatment of chronic hepatitis C virus infection, but is expensive and has several adverse effects. To modify this standard treatment by optimizing its therapeutic effect and decreasing its adverse events are important. Recent studies have identified a close link between metabolic profiles, insulin resistance and Hepatitis C Virus (HCV) infection. Several pilot studies in western world have have found beneficial effects of oral hypoglycemic agents on chronic Hepatitis C (CHC) genotype 1 infected patients. Whether this concept still holds true in Taiwanese people remains unknown.

The objective of this clinical trial is to evaluate the effect of oral hypoglycemic agents (daily for 4 weeks of run-in period and 8 weeks of combination treatment) on CHC genotype 1 infected Taiwanese patients receiving 48 weeks of Peg-IFN plus ribavirin (RBA), and the enrolled subjects will be randomized into 4 treatment groups (including Acarbose, Metformin, Pioglitazone and standard care control groups). During the trial and 24 weeks after the end of treatment, serial serum HCV RNA, alanine aminotransferase (ALT) levels, and other clinical data will be evaluated to determine the therapeutic response and adverse events of the CHC patients.

Pegylated interferon in combination with ribavirin is the current standard treatment of chronic hepatitis C virus infection, but is expensive and has several adverse effects. To modify this standard treatment by optimizing its therapeutic effect and decreasing its adverse events are important.

Recent studies have identified a close link between metabolic profiles, insulin resistance and HCV infection. Chronic hepatitis C (CHC) patients with higher pretreatment HOMA-IR (insulin resistance) index have poor therapeutic response than the ones with lower HOMA-IR index. Thus, it is reasonable to increase the therapeutic response of CHC patients by lowering insulin resistance. Several pilot studies in western world have been conducted to evaluate this concept by adding oral hypoglycemic agents into pegylated interferon plus ribavirin treatment, and have found beneficial effects of oral hypoglycemic agents on CHC genotype 1 infected patients. Whether this concept still holds true in Taiwanese people remains unknown.

To evaluate the effect of oral hypoglycemic agents on CHC genotype 1 infected Taiwanese patients, we design this study and evaluate the virologic, biochemical and histological responses of CHC patients receiving pegylated interferon plus ribavirin treatment, and hope to identify similar beneficial effects of oral hypoglycemic agents in CHC Taiwanese patients.

We plan to enroll about 80 chronic hepatitis C genotype 1 infected patients from the clinics into this study. All patients should have informed consent, not receive any interferon-based therapy or anti-viral medication, abstinence from alcohol beverage for more than 6 months and conformed to the regulations of Bureau of National Health Insurance, Taiwan. All patients will be randomly assigned into 4 different treatment arms. The patients assigned into the first 3 arms will receive one kind of the following oral hypoglycemic agents, such as Acarbose, Metformin, or Pioglitazone for 12 weeks (including 4 weeks of run-in period and 8 weeks of combination treatment with pegylated interferon alfa plus ribavirin). From week 13, all the patients of the first 3 arms will receive pegylated interferon alfa plus ribavirin for 40 weeks. The last arm is the control group; all the patients in the last arm will receive standard pegylated interferon alfa plus ribavirin treatment for 48 weeks. During the trial and 24 weeks after the end of treatment, the serum HCV RNA levels, clinical and biochemical data will be evaluated to determine the therapeutic response and adverse events of the patients.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Pioglitazone, Acarbose and Metformin in people with Chronic Hepatitis C, run by National Taiwan University Hospital at 1 site 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 7 inclusion and 13 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: status not confirmed, as of the sponsor's last update on 27 Nov 2012. 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 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.

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?

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 Virologic Response (time frame: at the end of 24 weeks post-treatment follow-up). 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 27 Nov 2012.
