About this study

Interferon-based monotherapy has been considered effective to treat acute hepatitis C in ordinary patients. However, the efficacy of this treatment has not been evaluated in prospective interventional studies for dialysis patients. The aim of the study is the evaluate the efficacy of peginterferon alfa-2a monotherapy for 24 weeks in this special clinical setting, and concomitantly evaluate retrospectively the dialysis patients with acute hepatitis C who did not receive intervention as the reference.

Read the detailed description

Chronic viral hepatitis is common in dialysis patients, with the reported prevalence and annual incidence of 3-80% and 2.9%, respectively. The high incidence and prevalence in thse patients are attributed to potential nosocomial exposure to hepatitis C virus during dialysis, resulting in high rates of acute hepatitis C virus infection. It is estimated that about 65-80% of the patients who have acute hepatitis C will evolve to chronic infection, leading to chronic hepatitis, cirrhosis, hepatic decompensation, and hepatocellular carcinoma (HCC). Currently, interferon and pegylated interferon monotherapy remains effective to treat acute hepatitis C in ordinary patients, with the sustained virologic response (SVR) rates ranging from 65-90% after 12-24 weeks of therapy. However, few data regarding the efficacy and safety of interferon-based monotherapy is known till now. Treatment of weekly 135 pegylated interferon alfa-2a has shown superior safety to thrice weekly 3 million unit (MU) standard interferon alfa-2a for dialysis patients with chronic hepatitis C. Under the excellent safety profiles of treating dialysis patients with low dose pegylated interferon alfa-2a, we aimed to evaluate the efficacy of weekly 135 ug pegylated interferon alfa-2a for a total of 24 weeks for dialysis patients with acute hepatitis C, and also evaluate the SVR rate by retrospective chart review for dialysis patients with acute hepatitis C who did not receive interferon-based therapy to evaluate if early intervention for these patients will improve overall disease outcome.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Pegylated interferon alfa-2a in people with Hepatitis C, run by National Taiwan University Hospital at 5 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 4 inclusion and 14 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 Dec 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 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.

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?

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?

Sustained virologic response (SVR) (time frame: 1.0 year). 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 Dec 2012.
