NCT ID: NCT01698723 Recruiting - Liver Failure Clinical Trials

A Trial of Ribavirin in Patients With ACLF Due to Hepatitis E Virus

HEVRibavirin
Start date: September 2012
Phase: Phase 2
Study type: Interventional

The term Acute on chronic liver failure (ACLF) describes a clinical entity characterized by an acute and rapid deterioration of liver function in a patient with previously well-compensated liver disease owing to the effects of a precipitating event. In this condition two insults act simultaneously, one being the preexisting liver injury (chronic liver disease) and the other acute injury which is responsible for the acute decompensation. HEV being a major factor responsible for this clinical entity and has a very high mortality rate. Ribavirin being a safe drug and has been shown to inhibit the replication of HEV, can be an important drug in the treatment of these patients. Therefore the present study is designed to study the impact of Ribavirin in reducing the mortality due to HEV related ACLF.

NCT ID: NCT01697501 Completed - Clinical trials for Hepatitis B, Chronic

A Study Evaluating IL28B Polymorphism in Patients With HBeAg-Negative Chronic Hepatitis B Treated With Pegasys (Peginterferon Alfa-2a) in Study ML18253

Start date: November 2012
Phase: Phase 3
Study type: Interventional

This cross-sectional multicenter study will evaluate the IL28B polymorphism in patients with HBeAg-negative chronic hepatitis B treated with Pegasys (peginterferon alfa-2a) in the predecessor ML18253 study. The study consists of a single visit where eligible patients will undergo a blood test for IL28B genotyping, with a phone follow-up 7 days after the visit.

NCT ID: NCT01690845 Recruiting - Acute Liver Failure Clinical Trials

Molecular Adsorbent Recirculating System (MARS®) in Hypoxic Hepatitis

MARS in HH
Start date: June 2012
Phase: Phase 2
Study type: Interventional

Hypoxic hepatitis (HH) is reported to be the most frequent cause of elevated aminotransferase levels in hospital. Up to 10 % of critically ill patients develop HH during the course of their intensive care unit (ICU) stay. Occurrence of HH is a life threatening event and ICU-mortality is reported to be up to 60%. Early therapeutic intervention is of central prognostic importance in patients with HH to improve the hemodynamic impairment as early as possible, to reduce hyperammonemia and hepatic encephalopathy, to avoid progression of organ failure and to improve outcome. Studies reported that Molecular Adsorbent Recirculating System (MARS®) therapy improved the hemodynamic situation in patients with acute and acute on chronic liver failure. The study hypothesis is that MARS® therapy in critically ill patients with severe HH improves hepatic hemodynamics and function and consecutively the course of the disease. 40 patients with suffering of severe HH with aminotransferase levels > 40 times the upper limit of normal of more than 12 hours will be randomized 1:1 to MARS® therapy (n=20) or conventional therapy (n=20). 4 MARS®-sessions will be performed on three consecutive days, each for at least 12 hours. Treatment will be continued under special circumstances. The maximum duration of the treatment phase is 7 days. The primary endpoint is the difference of the indocyanine plasma disappearance rate at day 7. The expected duration of the study is 2 years.

NCT ID: NCT01686789 Completed - Clinical trials for Chronic Hepatitis C Virus

Randomized Controlled Open Label Trial of Peg Alpha 2a Interferon and Adjusted-dose of Ribavirin vs. Standard Therapy in the Treatment of Naive Chronic Hepatitis C Patients Infected With Genotype 4

Start date: January 2011
Phase: Phase 4
Study type: Interventional

The study aims to study the outcome of pharmacokinetics-adjusted dose ribavirin (plus pegIFN) on the SVR in chronic HCV patients.

NCT ID: NCT01685203 Completed - Clinical trials for Hepatitis C, Chronic

A Study to Evaluate the Safety and Effect of Co-administration of ABT-450 With Ritonavir (ABT-450/r) and ABT-267 in Adults With Chronic Hepatitis C Virus Infection

PEARL-I
Start date: August 2012
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and efficacy of co-administration of ABT-450 (also known as paritaprevir) with ritonavir (ABT-450/r) and ABT-267 (also known as ombitasvir) in adults with chronic hepatitis C virus infection.

NCT ID: NCT01684787 Completed - Chronic Hepatitis C Clinical Trials

Study to Evaluate the Treatment for Chronic Hepatitis C With Normal Transaminases in HIV Positive Patients

CONTRA
Start date: September 2006
Phase: Phase 4
Study type: Interventional

In the current practice patients with normal levels of ALT were not treated. However, a percentage of patients will present an advanced grade of fibrosis and cirrhosis. Another reason to treat is the similar response to the treatment than elevated ALT patients published recently in mono-infected patients. The investigators have not data concerning the evolution and response to the treatment in co-infected patients with normal ALT. In the story of treatment chronic hepatitis C of co-infected patients HCV/HIV, sometimes, it assumes a behavior similar between mono and co-infected patients and the results are different. In the case of normal ALT the investigators do not know if the natural history in co-infected patients is similar than the mono-infected patients, and also the response of the treatment. This study prospective and controls is the answer of this question. The main hypothesis is if the response of treatment in co-infected patients is not inferior than mono-infected patients. The objective is to evaluate the efficacy and safety of peginterferon alfa-2a and ribavirin in HIV positive patients with chronic hepatitis and persistently normal ALT. Every CASE (patient with normal ALT) will have a CONTROL (patient with elevated ALT), concerning genotype, gender and hospital.

NCT ID: NCT01681420 Completed - HIV Clinical Trials

Improving Blood Safety and HIV Testing in Brazil

Start date: August 1, 2012
Phase: N/A
Study type: Interventional

Conduct a randomized controlled trial (RCT) to test the hypothesis that offering client-centered HIV counseling and testing (HCT) to blood donor candidates will reduce the risk of HIV contamination in the blood supply and also increase appropriate referrals to preventive and care services to persons in need in São Paulo, Brazil.

NCT ID: NCT01679834 Completed - Clinical trials for Hepatitis C, Chronic

An Observational Study of Pegasys in Dual- or Triple-Therapy in Patients With Chronic Hepatitis C

Start date: November 24, 2014
Phase: N/A
Study type: Observational

This multicenter, observational study will assess the efficacy and the safety of Pegasys (peginterferon alfa 2a) in dual- or triple therapy in patients with chronic hepatitis C. Patients will receive Pegasys and/or ribavirin and/or a protease inhibitor according to local guidelines. Data will be collected for 96 weeks.

NCT ID: NCT01678131 Completed - Chronic Hepatitis C Clinical Trials

Evaluating Fine Needle Aspiration to Measure Hepatic Vaniprevir (MK-7009) Concentrations in Participants With Chronic Hepatitis C (MK-7009-048)

Start date: October 30, 2012
Phase: Phase 1
Study type: Interventional

This study will evaluate the technical feasibility of using fine needle aspiration (FNA) of liver tissue to obtain vaniprevir (MK-7009) liver pharmacokinetic (PK) data, working towards identifying a minimally invasive, reproducible platform to measure liver PK. The study will be done in 2 parts. In Part 1, participants will be randomized to one of five FNA/core needle biopsy (CNB) time-point collection sequences. In Part 2, participants will be randomized to one of two possible doses of vaniprevir and will be assigned to one of five FNA/CNB time-point collection sequences; participants in Part 2 will also receive background therapy with pegylated interferon alpha-2b (Peg-IFN alpha-2b) and ribavirin (RBV). The primary hypothesis is that there is a greater than 80% posterior probability that vaniprevir concentrations are successfully obtained at least 60% of the time from FNA liver samples collected at 2 of 3 specified timepoints.
