Viral Kinetics and Liver Gene Expression in Response to Ribavirin and Peginterferon Therapy of Chronic Hepatitis C
NCT00718172 · View on ClinicalTrials.gov ↗
Study Summary
Up to 120 patients with chronic hepatitis C will be enrolled in a study of viral kinetics and liver gene expression before and during combination therapy with peginterferon and ribavirin. Adult patients with chronic hepatitis C virus (HCV) infection who have compensated liver disease and have not received interferon in the past will be randomized into one of four groups. Groups A and C will undergo liver biopsy before starting peginterferon therapy and Groups B and D will undergo biopsy 6 hours after the initial dose of peginterferon. Furthermore, Groups C and D will receive a run-in period of 4 weeks of ribavirin therapy before starting peginterferon. All patients will receive the standard recommended doses of peginterferon alfa 2a (180 mcg sc weekly) and ribavirin (1000 or 1200 mg daily for genotypes 1, 4-6 and 800 mg daily for genotype 2 and 3) for up to 48 weeks (24 weeks for genotype 2 and 3). All patients in Groups C and D, irrespective of genotype, will be pretreated with ribavirin at a dose of 1000 or 1200 mg, depending on patient body-weight. After the initial peginterferon injection, patients will have blood taken and symptoms recorded at 6, 24, 48, 72 hours and weekly thereafter for four weeks to assess viral kinetic response. Liver biopsy tissue taken before or 6 hours after the initial dose of peginterferon will be assessed by standard light microscopy and also subjected to RNA extraction and microarray analysis of mRNA expression. Patients will be monitored carefully during therapy and tested regularly for HCV RNA levels. Therapy will be given for 48 weeks, but will be discontinued early for patients with genotype 1 infection if HCV RNA levels do not decline by at least 2 log IU/ml by week 12 (lack of an early virological response) or do not decline to undetectable levels by week 24 (lack of HCV RNA clearance). Patients with other genotypes with be treated for a full course of therapy regardless of early responses. After completing therapy, patients wi

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00718172
The ClinicalTrials.gov registry entry for NCT00718172 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 81 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), which has 375 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Hepatitis C, Chronic appearing as the primary indexed condition, and to 3 interventions — of which Liver Biopsy is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00718172 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
