Active clinical trials for "Hepatitis A"

The aim of this randomized clinical study is to show non-inferiority of a change of anti-viral therapy from telbivudine to lamivudine in patients who have achieved an undetectable viral load at week 24 of telbivudine therapy compared to continuous treatment with telbivudine with respect to the viral breakthrough rate at week 108 as the primary clinical outcome.

To show the feasibility of liver transplantation in HCV-HIV coinfected patients. To study the two-year survival after transplantation, the interaction between HCV and HIV after transplantation, the influence of HIV on HCV recurrence after transplantation, the interaction between immunosuppressive and antiretroviral drugs in particular anti-proteases, immunological follow-up and quality of life of these patients

The purpose of this study is to develop a clinical understanding of early liver transplantation (ELT) for patients with severe alcoholic hepatitis (SAH) and identify the public's opinion regarding this practice.

The study is aimed to provide high-risk, HIV-infection, men who have sex with men (MSM) with healthcare education regarding viral hepatitis C, through either serious game intervention or traditional online health education. After the education, each participants will be followed for 48 weeks and the change of risky sexual behaviors, acquisition of HCV and other STIs will be followed during the study periods.

This is a Phase 3b/4, prospective, open-label, randomized, multicenter study of peginterferon alfa-2b plus ribavirin in participants with chronic hepatitis C, genotype 1. The study consists of two parts: (1) a noninterventional arm (HOMA IR <= 2) and (2) an interventional arm (HOMA IR > 2), where HOMA IR is the insulin resistance index for the participants calculated by fasting insulin (uU/mL) x [fasting glucose (mmol/L)/22.5]. Participants in the noninterventional arm are treated according to the European labeling and response rates are evaluated at Month 1 (optional), 3, 6, 12, and follow up. Participants in the interventional arm are treated with PEG-Intron 1.5 ug/kg (subcutaneous) once weekly plus weight-based REBETOL 800-1400 mg (oral capsules) daily for a variable period depending on their response at Week 12: (1) HCV-RNA positive with < 2-log drop in viral load, treatment will be discontinued; (2) HCV-RNA positive with >= 2-log drop in viral load; participants will be randomized (1:1) to Group A (stop treatment at Week 48) or Group B (stop treatment at Week 72); and (3) HCV-RNA negative, treatment will be changed to be according to the European labeling and response rates will be evaluated at Month 6, 12, and follow up. All participants will go on with their treatment after Week 12 until the results of the HCV polymerase chain reaction (PCR) are available (maximum of 4 weeks).

This study will evaluate the hepatic (liver) and plasma pharmacokinetics of Vaniprevir (MK-7009) by evaluation of ribonucleic acid (RNA) of the hepatitis C virus (HCV) in genotype 1, HCV-infected participants.

This study is designed to test two separate strategies for treatment of anemia (low hemoglobin) and neutropenia (low white blood cells) in HIV/HCV coinfected patients who are being treated with pegylated interferon and ribavirin.

HCV infection is treated with oral drugs, termed as 'direct-acting anti-viral agents' (DAAs). In India, four DAAs are available (sofosbuvir [SOF], daclatasvir [DCV], ledipasvir [LDV] and velpatasvir [VEL]). Globally, DAA based regimens have obtained excellent rates of cure. Cure of HCV infection is defined as undetectable HCV RNA 12 weeks after stopping drugs, also referred to as sustained virological response at week 12 (SVR12). Using these DAA based treatment regimens, a small number (up to 5%) of people fail to achieve SVR12 and HCV RNA reappear after a few weeks of stopping the drugs (virological relapse). Data on management of virological relapse are extremely limited, especially in genotype 3, and no guidelines exist regarding re-treatment options for such group. Hence, we plan to re-treat such people using what appear to be the best combination treatment in each situation and to review our experience over time. Participants with chronic HCV infection who relapsed following standard DAA-based treatment regimen will be invited to participate. We propose to re-treat them with the anti-HCV drug combination which appears to be the most suited to his/her clinical profile, based on the current empiric knowledge - the choice of drugs will be based on HCV genotype, the previous treatment regimen and the presence/absence of liver cirrhosis, etc. During anti-HCV treatment, participants will be given expected standard of care and HCV RNA will be tested at 4-week intervals starting from week 4 and till RNA becomes undetectable, and then at the end of treatment and 12 weeks after the treatment was stopped - as is the usual practice during such treatment. Relevant clinical, laboratory and treatment details will be recorded in a pre-defined data collection form. Treatment outcome will be categorized as success (SVR12), treatment failure (any detectable HCV RNA at the end of 24 weeks treatment duration) or relapse (HCV RNA negative at the end of treatment, but positive at 12 weeks after stopping treatment). If possible, a 5-ml blood specimen will be collected before starting re-treatment from all participants; in addition, another similar specimen will be collected following the treatment in those in whom the re-treatment is unsuccessful. These will be stored and may be used in future for virological studies to look for drug-resistance variations.

The aim of the study is to screen for hepatitis B, hepatitis C and AIDS viruses using a Dried Blood Spot in drug users

The primary objective of this study is to assess changes in alanine aminotransferase (ALT) in hepatitis C virus (HCV)-infected subjects given daily doses of JKB-122 for 3 months who have been nonresponsive to, intolerable to, or relapsed from prior interferon-based therapies (pegylated or standard) either alone or in combination with ribavirin or other anti-HCV therapies including direct-acting anti-viral agents.
