Active clinical trials for "Hepatitis B, Chronic"

This prospective, multicenter, observational study will evaluate on-treatment predictors of response in patients with HBeAg positive or HBeAg negative chronic hepatitis B receiving treatment with peginterferon alfa-2a (PEGASYS®) in accordance with local labeling and the summary of product characteristics. Data will be collected from patients for the duration of their treatment and for up to 24 weeks thereafter.

The purpose of this study is to compare the liver toxicity in HIV-infected patients with chronic hepatitis B and/or hepatitis C, who start a new antiretroviral drug regimen, as well as the influence of the degree of pre-existing liver fibrosis on the incidence of liver toxicity.

This open--label, multicenter, national observational study will investigate the effectiveness of standard of care treatment with peginterferon alfa-2a in participants with chronic hepatitis B (CHB). Participants who have never received any hepatitis B virus (HBV) treatment and participants previously treated with nucleos(t)ide analogs (NAs) are qualified for enrollment. The observation period is 48 weeks (peginterferon alfa--2a standard of care treatment) and for up to 24 weeks thereafter (72 weeks in total).

The purpose of this study is to collect epidemiological data in children and adolescents with chronic hepatitis B(CHB), in particular data on the prevalence of HBeAg positive disease with associated ALT levels , active HBeAg negative disease and decompensated CHB in the pediatric population. Family history and history of HBV transmission is essential to assess the course of the disease and can be used to determine the best mode of treatment This information will be used to assist with the feasibility and design of studies for the Novartis clinical pediatric development program, as the current epidemiology of ediatric CHB is not accurately known in Western countries or the rest of the world making pediatric studies difficult to plan and conduct. This study forms part of the Novartis Pediatric Investigational Plan, a post marketing approval commitment to the EMEA Pediatric Committee.

Background and rationale Chronic hepatitis B is the most common cause of liver cirrhosis and hepatocellular carcinoma worldwide.(1) Antiviral therapy with oral nucleoside analogs and interferon can reduce viral load and hepatic necroinflammation, and may reduce the risk of hepatocellular carcinoma and cirrhotic complications. (2-4) Peginterferon has both direct antiviral and immunomodulatory effects. The advantages of this drug include a finite course of treatment and the lack of drug resistance. However, it requires subcutaneous injections and carries some side effects. Besides, only 30% to 40% of treated patients have sustained response to treatment.(5-8) To reduce the costs and side effects of treatment, it is important to predict if a patient will respond to peginterferon. Genetic host studies on peginterferon response will provide a lot of knowledge on the interaction between the host and the virus to induce immune control, also outside the setting of immune modifying therapy. Recently, genome wide association studies (GWAS) identified genetic polymorphisms of the IL28B gene that were shown to be associated with treatment response to interferon and ribavirin in patients with chronic hepatitis C.(9-12) The same polymorphisms are also associated with natural clearance of hepatitis C virus. Whether the same phenomenon applies to patients with chronic hepatitis B is unclear. Furthermore, response to conventional interferon has shown to decrease the risk of hepatocellular carcinoma and to prolong survival.(13) Virological and serological response to PEG-IFN is durable in a substantial proportion of patients through 3 years of follow-up (14), but whether treatment benefits are sustained after that period and amount to clinically meaningful results is unknown. To date, a GWAS to predict the response to peginterferon in chronic hepatitis B patients has not been performed. Polymorphisms in genes such as IL28B can be identified through a GWAS and can be used to assess the chance of response to treatment and select patients who have a high probability of response to peginterferon. We aim to perform a GWAS in chronic hepatitis B patients previously treated with peginterferon to identify polymorphisms in genes that are associated with response to this treatment regimen.

This observational, non-interventional cohort study will evaluate predictors of response in patients with chronic hepatitis B receiving standard of care Pegasys therapy. Efficacy and safety parameters will also be evaluated. Patients included in the study will be followed for the duration of their treatment and for up to 3 years thereafter.

This study will explore HBV kinetics in CHB patients during the first 24 weeks of treatment with telbivudine

This study is a retrospective study. Enrollment study.

Explore the relevance of effective diagnosis of liver changes. To explore the characteristics of clinical indicators that can effectively diagnose liver histopathological changes, and to provide clinical indicators for patients with chronic hepatitis B to receive timely treatment of histopathological changes, and provide important evidence for patients with chronic hepatitis B to receive timely treatment.

This study was a retrospective clinical observational cohort study. All patients with chronic hepatitis B (CHB) whose HBsAg decreased by less than 10% were treated continuously with interferon in the Department of Hepatology, Beijing Ditan Hospital, Beijing Medical University, Beijing Capital University, 2008.10-2017.4. The total interferon treatment time of the enrolled subjects was 48 weeks. The subjects were randomly divided into the following two observation cohorts: 1) patients with chronic hepatitis B treated with continuous interferon for 48 weeks; 2) intermittent interferon For 48 weeks of treatment for patients with chronic hepatitis B, the interferon treatment interval was 3 months. HBV DNA content, HBsAg/anti-HBs, HBeAg/anti-HBe and biochemical markers, serum AFP and liver imaging (liver ultrasound) were collected before treatment (baseline) and during treatment. The primary outcome measure was the rate at which HBsAg disappeared at 48 weeks of treatment. The secondary evaluation index was the 48-week HBeAg seroconversion rate. To investigate the efficacy, influencing factors and safety of interferon intermittent treatment of chronic hepatitis B.

This is a local, prospective observational study (regulatory post marketing surveillance) to access the safety and effectiveness of Baraclude in Korean pediatric patients with chronic HBV infection who are between the ages of 2 and less than 16 years.
