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.

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).

Ribavirin: Clinical Trials, Market Analysis, and Projections

Introduction

Ribavirin, a nucleoside analogue, is a versatile antiviral drug used in the treatment of various viral infections, including hepatitis C, Lassa fever, and other viral diseases. This article delves into the current state of clinical trials, market analysis, and future projections for ribavirin.

Clinical Trials and Efficacy

Lassa Fever Treatment

Ribavirin remains the primary treatment for Lassa fever, particularly in endemic areas. A recent study highlighted the importance of viral load kinetics in patients treated with ribavirin. The study found that the cycle threshold (Ct) value on admission has prognostic value, and patients typically clear the virus within 3-4 weeks of hospitalization. This information is crucial for designing clinical case management and future clinical trial protocols[1].

Hepatitis C Treatment

Ribavirin is commonly used in combination with interferon drugs (such as peginterferon alfa-2a or peginterferon alpha-2b) to treat hepatitis C. Clinical trials have shown that this combination therapy is effective, especially for patients who have never received interferon before. However, ribavirin can cause severe anemia, necessitating dose adjustments in some patients[3][4].

Other Indications

Ribavirin has been explored for its potential in treating other viral infections, such as hepatitis E and coronavirus disease 2019 (COVID-19), although its effectiveness in these areas is still under investigation and considered experimental[4].
