Active clinical trials for "Hepatitis A"

To determine the effect of an integrated care protocol on antiviral treatment and sustained virologic response (SVR) rates following initiation of direct acting antiviral therapies (DAA) treatments in 2011.

Subjects are being asked to take part in a research study to test two levels of alcohol services for patients with hepatitis C virus (HCV) who drink alcohol. The two levels differ in intensity of alcohol services and in whether or not they include a focus on liver health. The study will look at which level of alcohol services best decreases alcohol use among patients with HCV.

Hepatitis C Virus, (HCV), infection is a major health concern in the UK with up to 0.7% of the population infected. At best, 25% of those infected will clear the infection spontaneously, though for those who develop a chronic infection, they may go onto to develop liver cirrhosis or liver cancers. The standard of care within the NHS is that patients with a history of intravenous drug use or those currently on methadone are at high risk of having HCV infection and should be offered HCV testing. Once diagnosed they can be referred to nurse led treatment pathways. Less than 10% of the methadone users are even tested for HCV and of them fewer than 20% go onto treatment regimens that successfully clear the infection despite regular interactions with heath care staff. Pharmacists who have daily interactions with patients receiving methadone are ideally placed to deliver anti HCV therapy as they have daily contact with this client group and are well placed to advise on the drug therapy. The SuperDOT C study will examine the impact of pharmacy led Directly Observed Therapy (DOT) for HCV treatment in patients attending Community Pharmacies in participating Health Boards within NHS Scotland. The impact of this approach will be compared with those referred to standard care pathways on how well participants clear their HCV infection.

The purpose of this study is to evaluate the efficacy and safety of triple therapy of AbbVie adults with chronic hepatitis C virus ("HCV"), who have not responded to prior treatment with protease inhibitors. The "Triple therapy" of AbbVie attacks various sites of the viral genome, thus increasing the potential efficacy of the treatment, especially for patients who have failed PI treatment.

A Phase 1, First-in-Human, Randomized, Placebo-Controlled, Double-Blind Study to Evaluate the Safety, Tolerability, and Pharmacokinetic Profiles of Single Ascending and Multiple Oral Doses of MB-110 in Healthy Volunteers and to Evaluate the Antiviral Activity of MB-110 in Hepatitis C Virus Infected Subjects

Patients with chronic hepatitis C that are under opiate substitution therapy are likely to have psychiatric comorbidities such as depression; hence an Interferon based therapy is contraindicated. Additionally many of these patients have a borderline compliance, which makes it impossible to treat them at specialized hepatological centers. An ideal opportunity to treat this patients is treatment with DAAs (Direct Acting Antiviral) which can be administered daily together with the opiate substitution therapy at a low threshold facility.

This is a nonrandomized, open-label, no-control, dose-escalation Phase 1b trial in 18 patients with chronic HBV infection to determine the safety, preliminary efficacy, and pharmacokinetics (PK) of QL-007 after administration over 28 days of multiple oral doses in a fasted state at the following planned dose levels: 200 mg/day (100 mg two times a day (BID)), 400 mg/day (200 mg BID), then 600 mg once daily (QD), with 6 patients for each cohort.

Chronic Hepatitis B is the most common cause of chronic viral liver disease worldwide afflicting 350 million persons, leading to significant morbidity and mortality due to liver disease and HCC in 20-40% of infected persons. With the advent of nucleoside analogues, this rescued patients with significant risk of disease progression, but in most circumstances, therapy was needed long term as HBsAg seroclearance was an uncommon occurrence, and stopping therapy was associated with relapse of disease and hepatitis B flares. The use of pegylated interferons showed increased HBeAg seroconversion and HBsAg seroclearance rates compared to nucleoside analogues , however combination nucleos(t)ide analogue therapy has been quite disappointing. However a recent showed that the combination of telbivudine and tenofovir in a response guided therapy design, had a remarkable 6% HBsAg seroclearance at week 52 in patients. Such results require further confirmation. There is currently an unmet need for the large number of patients on long term nucleoside analogue therapy who have not achieved HBeAg seroconversion or HBsAg seroclearance. Such patients are seeking alternatives to long term therapy hence an exploration of other therapeutic strategies is attractive. An additional benefit of telbivudine has been the surprising improvement in renal function and this study seeks to examine whether this can improve the renal impairment that may be seen with tenofovir. Our study proposes to examine if the combination of tenofovir and telbivudine can improve endpoints. Patients fulfilling inclusion and exclusion criteria will be randomized to tenofovir or tenofovir and telbivudine (1:1 ratio). The primary endpoint will be a qHBsAg reduction of >1log at week 96, which may predict future HBsAg seroclearance, which is also a secondary endpoint. An additional primary endpoint is increase in eGFR in the combination arm compared to the monotherapy arm. The study aims to enroll 146 patients randomized 1:1 ratio (73:73) patients. Multivariate analysis will be performed of baseline and on-treatment factors that predict the primary outcome.

The purpose of this study is to compare efficacy and safety of continuing Lamivudine plus Adefovir or Adefovir versus switching to Entecavir plus Adefovir in patients with LAM-resistant chronic hepatitis B who have suboptimal response to Lamivudine plus Adefovir or Adefovir

This Registry will enroll adolescent and pediatric participants who received at least one Gilead Hepatitis C Virus (HCV) direct acting antiviral (DAA) while participating in a Gilead-sponsored chronic hepatitis C clinical trial. The primary objective of this Registry is to determine the long-term safety of anti-HCV regimens in the pediatric population. Secondary objectives of this Registry are to determine whether subsequent detection of HCV RNA in participants who relapse following sustained virologic response (SVR) represents the re-emergence of pre-existing virus, the development of resistance mutations, or whether it is due to re-infection, and to characterize resistance mutations and the persistence of resistance mutations in pediatric participants who did not achieve SVR. Once enrolled, participants will be followed for up to 5 years.
