All Clinical Trials for Ribavarin
| Trial ID | Title | Status | Sponsor | Phase | Start Date | Summary |
|---|---|---|---|---|---|---|
| NCT00502970 ↗ | Short Course of Interferon Treatment in Patients With HCV Infection | Completed | Getz Pharma | Phase 4 | 2004-05-01 | To determine if a shorter course of interferon and ribavirin therapy will be sufficient in carefully selected patients with chronic hepatitis C virus genotype 3 infection, as compared to the standard length of treatment of 6 months. |
| NCT00502970 ↗ | Short Course of Interferon Treatment in Patients With HCV Infection | Completed | Aga Khan University | Phase 4 | 2004-05-01 | To determine if a shorter course of interferon and ribavirin therapy will be sufficient in carefully selected patients with chronic hepatitis C virus genotype 3 infection, as compared to the standard length of treatment of 6 months. |
| NCT00703872 ↗ | HDV-Interferon in the Treatment of Chronic Hepatitis C Nonresponders and Naive Hepatitis C Patients | Unknown status | Hepasome Pharmaceuticals | Phase 2 | 2008-05-01 | A Phase II, Open Label, Multi-Center, Proof-Of-Concept Study determing whether treatment with HDV-Interferon (HDV-IFN), by oral or subcutaneous (injection) routes, and ribavirin results in similar efficacy [Rapid Virologic Response (RVR)] and safety as the reported efficacy and safety with pegylated alpha-interferon-2a and ribavirin (historical control) in patients with chronic hepatitis C (treatment naïve by oral route and non-responders by SC route respectively). |
| NCT00842205 ↗ | Role of Heme Oxygenase in the Pathogenesis of Hepatocellular Injury in Chronic Hepatitis C Virus (HCV) Infection | Unknown status | IGA MZ, Czech Republic | N/A | 2007-01-01 | In the presented project, the role of heme oxygenase 1 and 2 in the procesess associated with fibroproduction in the chronic HCV infection will be studied. Heme oxygenase expression will be evaluated by the techniques of molecular genetics and immunohistochemistry, both in the liver tissue and in peripheral blood mononuclear cells. These parameters will be correlated with basic virological and clinical characteristics of the chronic HCV infection. The investigators' expected results may help in understanding the mechanisms of fibroproduction in chronic HVC infection and, therefore, contribute to explain individual differences in the development of chronic HCV infection. |
| NCT00842205 ↗ | Role of Heme Oxygenase in the Pathogenesis of Hepatocellular Injury in Chronic Hepatitis C Virus (HCV) Infection | Unknown status | Charles University, Czech Republic | N/A | 2007-01-01 | In the presented project, the role of heme oxygenase 1 and 2 in the procesess associated with fibroproduction in the chronic HCV infection will be studied. Heme oxygenase expression will be evaluated by the techniques of molecular genetics and immunohistochemistry, both in the liver tissue and in peripheral blood mononuclear cells.

| NCT01458080 ↗ | WEUSKOP5410: Observational Study in ENABLE Clinical Trials | Completed | GlaxoSmithKline | 2011-05-01 | Hepatitis C Virus (HCV) is a leading cause of chronic liver disease (CLD) worldwide. Current mainstay of treatment is combination therapy with pegylated interferon and ribavarin. Thrombocytopenia as a treatment related adverse event or a complication of chronic liver disease often necessitates dose reduction and discontinuation in these patients. Revolade®/Promacta® (eltrombopag) is an oral second generation thrombopoietic growth factor in development for the treatment thrombocytopenia associated with various conditions, including secondary thrombocytopenia related to CLD and hepatitis C. In 2009 a phase III trial for CLD patients undergoing an elective invasive procedure (ELEVATE) was terminated early due to an imbalance of thromboembolic events (TEE) between the placebo and the eltrombopag arm. Currently, two global interventional Phase III trials (ENABLE 1 and ENABLE 2) are being conducted in approximately 1500 patients to evaluate the efficacy of eltrombopag in enabling HCV patients to achieve sustained viral response. Due to the similarities between the patient groups in ELEVATE and ENABLE, there is a concern that invasive procedures may influence the risk of TEE in the ENABLE population. This observational, non-interventional, retrospective, multicentre, nested case-control study will collect data from chart abstraction and medical record review to augment data from the ENABLE case report forms particularly with regards to invasive procedures. The study population includes cases and controls drawn from the ~1500 participants of the ENABLE trials. All eligible cases of TEE will be included in the study as cases. All other patients who participated in the ENABLE trials and did not experience a TEE, will be eligible to be selected as controls. Case report forms will be developed to enable standardized data capture. The Sponsor has contracted with the Clinical Research Organization, Outcome Sciences Inc to manage the study. ENABLE investigators will work with Outcome staff to obtain relevant information from the treating physician (e.g. surgeon) and the facility where the invasive procedure was performed (pre-operative tests, peri-operative course, diagnostic testing for TEE). Single point abstraction will be performed to obtain data from the medical record and from any additional data resources obtained by the investigator (e.g., operative note, anesthesia record). Analyses will be conducted using logistic regression models to estimate the risks. The primary objective of the study is to evaluate if there is an increased risk for TEE among patients who had an invasive procedure while exposed to eltrombopag (during the ENABLE trials). | |
