NCT ID: NCT01548820 Completed - Clinical trials for Chronic Hepatitis B Virus Treatment

Resistance to Lamivudine in HBV Egyptian Patients

Start date: June 2010
Phase: N/A
Study type: Observational

On treatment parameters for Lamivudine resistance in HBV treated Egyptian patients

NCT ID: NCT01532843 Completed - Chronic Hepatitis B Clinical Trials

Lowering Viral Load With Nucleos(T)Ide Analogues Prior to Peginterferon Treatment to Ncrease Sustained Response in CHB

PEGON
Start date: June 2012
Phase: Phase 4
Study type: Interventional

Treatment with a nucleoside analogue and subsequent viral decline has shown to partially restore immune hyporesponsiveness in chronic hepatitis B patients. Recent pilot studies investigating whether the effect of lowering viral load with nucleoside analogue therapy prior to the initiation of peginterferon results in higher sustained off-treatment responses showed contradictory findings. The aim of this study is to investigate sustained off-treatment response to peginterferon alfa-2b in chronic HBeAg-positive hepatitis B patients who are pretreated with nucleos(t)ide analogues, thereby lowering viral load

NCT ID: NCT01531166 Completed - Chronic Hepatitis B Clinical Trials

A Cohort Study in Korean Patients With Chronic Hepatitis B (CHB) Receiving Pegylated Interferon

Start date: September 2011
Phase: N/A
Study type: Observational

The current proposed study aims to bring answers following issues: the antiviral efficacy and safety profiles in Korean Chronic Hepatitis B (CHB) patients who are mostly infected with solely genotype C HBV, a proper duration of Pegasys® therapy post-treatment durability or accumulation of HBeAg seroconversion/HBsAg loss, preventable effect on long-term disease progression to liver cirrhosis and liver cancer. In addition, this study aims to collect more data on the efficacy and safety in a real-life clinical setting of Pegasys® therapy in patients with CHB.

NCT ID: NCT01531075 Completed - Clinical trials for Inflammatory Bowel Disease

Hepatitis B Vaccine in Patients With Inflammatory Bowel Disease

HBV VIP
Start date: April 2012
Phase: N/A
Study type: Interventional

The objective is to assess the efficacy of Hepatitis B Virus vaccination in a population of IBD patients treated with immunosuppressive medications.

NCT ID: NCT01524679 Completed - Chronic Hepatitis B Clinical Trials

Peg-interferon ADDed to an Ongoing Nucleos(t)Ide Based Treatment in Patients With Chronic Hepatitis B to Induce Decrease of HBs-Antigen

PADD-ON
Start date: August 2012
Phase: Phase 2
Study type: Interventional

A prospective, randomised, open-label phase IIb clinical trial assessing the effect of pegylated interferon alfa-2a(Pegasys®) 180 μg once weekly for 48 weeks added to an ongoing nucleos(t)ide based treatment in patients with chronic HBeAg-negative hepatitis B The primary objective of the trial is to investigate whether the add-on of pegylated interferon alfa-2a to a continued treatment with nucleos(t)ide analogues increases the percentage of patients who have significant decrease (≥ 1log10) of HBs antigen after 48 weeks. 170 Patients with chronic hepatitis B, HBe antigen negative, already being treated with an oral antiviral regimen and having a nondetectable viral load for at least 12 months are included.

NCT ID: NCT01522625 Completed - Chronic Hepatitis B Clinical Trials

Tenofovir in Chronic Hepatitis B With Mild ALT Elevation

Start date: January 2012
Phase: Phase 4
Study type: Interventional

This study aims to clarify whether patients with chronic hepatitis B with high viral load will benefit from oral antiviral therapy despite only mildly elevated serum liver enzyme.

NCT ID: NCT01521975 Completed - Clinical trials for Hepatitis B, Chronic

A Two-year Study of Telbivudine in HBeAg Negative Hepatitis

STEN
Start date: January 1, 2011
Phase: Phase 4
Study type: Interventional

Based on GLOBE study supplying predictability analysis results, ROADMAP strategy provides an individualized telbivudine treatment roadmap strategy designed to achieve optimal viral suppression and low resistance rate in patients with chronic hepatitis B(CHB), which includes adding ADV treatment at different time points according to individual patient response. China CHB Guidelines (China Medical Association 2010) make impress on and confirm LDT ROADMAP strategy particularly, which may be a large potential to expand the naïve patients. We are lack of optimal model in HBeAg(-). In China HBeAg(-) is around 38% of total CHB patients. In GLOBE study, LdT treatment against HBeAg(-) patients with HBV DNA <7log showed a good 2 year efficacy, but we still look forward to more efficient treatment and lower resistance rate. This study complies with the principle of individualized therapy recommended and ethical principles. It is expected that this study design with individualized treatment approach may improve efficacy and lower the resistance rates. In addition, it will provide important information on how to bring greater benefits to patients with CHB.

NCT ID: NCT01519960 Completed - Clinical trials for Hepatitis B, Chronic

A Study of Pegasys (Peginterferon Alfa-2a) Versus Untreated Control in Children With HBeAg Positive Chronic Hepatitis B

Start date: July 11, 2012
Phase: Phase 3
Study type: Interventional

This parallel group, open label study will evaluate the safety and efficacy of Pegasys (peginterferon alfa-2a) versus untreated control in children (age 3 years to <18 years at baseline) with HBeAg positive chronic hepatitis B. Children without advanced fibrosis and without cirrhosis will be randomized 2:1 to treatment Group A, receiving Pegasys 45-180 mcg subcutaneously weekly for 48 weeks, or to the untreated control Group B. Children with advanced fibrosis will be assigned to treatment group C and receive 48 weeks of treatment with Pegasys. Children in the untreated control Group B who have not experienced seroconversion 48 weeks after randomization may enter the Switch Arm to receive 48 weeks of Pegasys treatment. This offer will be available for 1 year following 48 weeks from randomization. Anticipated time on study treatment is 48 weeks. All subjects will be followed up for 5 years after the end of treatment (A,C,Switch)/principal observation (B) period.

NCT ID: NCT01519921 Completed - Clinical trials for Hepatitis B, Chronic

A Study of PEGASYS (Peginterferon Alfa-2a (40KD)) in Patients With HBeAg Positive Chronic Hepatitis B.

Start date: October 2005
Phase: Phase 4
Study type: Interventional

This study will evaluate the efficacy and safety of PEGASYS (peginterferon alfa-2a) in patients with HBeAg positive chronic hepatitis B. Patients will be stratified into group A (treatment naïve patients) or B (YMDD mutant patients). All patients will receive PEGASYS 180 micrograms subcutaneously once weekly for 48 weeks, followed by 24 weeks of treatment-free follow up.
