About this study

Official title: Non-insulin-dependent Diabetes Mellitus and Insulin Resistance in Chronic Hepatitis C Patients Treated With Combination Therapy With Pegylated Interferon and Ribavirin in Taiwan

The influence of insulin sensitivity and glucose tolerance on the effects of antiviral therapy for HCV remains unclear. The aim of the present study was (1) To elucidate the clinical and virological factors associated with sustained viral response in patients with combination therapy with PEG-IFN and ribavirin. (2) To clarify the influence of diabetes mellitus (DM), impaired glucose tolerance test (IGT) and insulin resistance (IR) on the HCV response to combination therapy with PEG-IFN and ribavirin. (3) To test the influence of combination therapy on HOMA IR

Read the detailed description

Total 300 treatment-naïve chronic hepatitis C patients will be enrolled. The prevalence of NIDDM, IGT and IR will be explored in this hospital-based study among the clinically defined chronic hepatitis C Taiwanese. The clinical manifestations of chronic hepatitis C in the biochemical, virological and histopathological aspects will be evaluated. Liver enzymes will be measured on a multichannel autoanalyzer. Virological markers for HCV including serum HCV RNA detected using a standardized automated qualitative PCR assay, HCV RNA genotypes determined for genotypes 1a, 1b, 2a, 2b and 3a and serum HCV RNA levels measured by using the branched DNA assay. The liver histology will be assessed for scoring the disease activity grade quantitatively according to the histological activity index (HAI). Patients are assigned a diagnosis of DM if there was documented use of oral hypoglycemic medication or insulin, random glucose in excess of 200 mg/dL, or fasting glucose greater than 126 mg/dL on two occasions. A standard oral glucose tolerance test (OGTT) will be performed. In addition to an OGTT, a history of diabetes mellitus by chart review and/or questionnaire will be also obtained. Standard antiviral therapy will be carried out with PEG-IFN, given subcutaneously weekly plus 1,000-1,200 mg of oral ribavirin daily. Patients will receive another 24 week of follow-up period to determine the virological response.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Aug 2009. 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.

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 virological response (SVR) rate, HCV RNA seronegative by PCR throughout 24-week off-treatment period; biochemical, virological and histological characteristics of CHC patients; HOMA-IR change after combination therapy (time frame: 18 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00687999, which also lists 6 linked publications.

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 6 Aug 2009.
