Active clinical trials for "Hepatitis A"

This observational study will evaluate predictors of early on-treatment response and sustained virological response in patients with chronic hepatitis C receiving Pegasys (peginterferon alfa-2a) and ribavirin. Data will be collected from patients on treatment (24 or 48 weeks) and 24 weeks after the end of treatment.

The purpose of this study is to determine if there is an association between hepatitis C infection and kidney cancer. All patients who are diagnosed with kidney cancer and who will either have a biopsy or surgery will be offered to be tested for hepatitis C. The control group will be colon cancer patients. Both groups would be of recent diagnosis (6 months).

This observational study will assess predictors of early on-treatment and sustained virological response in treatment-naïve patients with chronic hepatitis C initiated on treatment with Pegasys (peginterferon alfa-2a) or peginterferon alfa-2b and ribavirin. Data will be collected during the treatment period (24 or 48 weeks) and 12 and 24 weeks after the end of treatment. Target sample size is <2000.

This is to evaluate the proportion of subjects who show good responses to LAM treatment in Korea.

The objective of the study is to evaluate, in each group, the number of participants who achieve rapid virological response (RVR) after 4 weeks treatment with PegIntron and Rebetol. The study will also assess whether RVR is a reliable predictor of sustained virologic response (defined as undetectable viral load at 24 weeks post-treatment).

The objective of this study is to assess the impact of participant care and support on treatment adherence. PegIntron pen and Rebetol will be administered to participants with Hepatitis C Virus (HCV) in accordance with approved labeling. Sites will be categorized as providing high vs low level of participant management based on information about the level of participant support and management captured on the site questionnaire. Data on each participant will be collected by a physician on an electronic participant case report form (CRF) and by the participant via a questionnaire. Treatment completion rates will be analyzed based on the high vs low level of participant management. The hypothesis is that Physicians investing more time and effort into participant management achieve higher treatment completion rates among their hepatitis C patients than physicians offering less participant management measures.

Participants with Chronic Hepatitis C (CHC) and normal ALT, who have been under treatment with peginterferon alfa-2a and ribavirin for at least 4 weeks, will be enrolled into this non-interventional, open-label study. The primary aim is to evaluate quality of life according to the 36-Item Short-Form Health Survey (SF-36) questionnaire, modified for the Greek population.

The purpose of this study is to describe the genetic diversity of Hepatitis C virus (HCV) NS3/4a protease and NS5A protein of HCV in participants with chronic disease naive-drug or previously failed to double therapy (Peg-interferon and Ribavirin) and to identify the frequency of natural polymorphisms in HCV NS3/4a protease and NS5A protein that are associated with direct-acting antivirals (DAAs)-resistance.

The aim of this study is to prove the superiority of entecavir over lamivudine for preventing the risk of hepatitis B virus reactivation in patients with non-Hodgkin lymphoma on CHOP/R-CHOP.

This study is being conducted to develop new techniques for early diagnosis of liver disease. These techniques are: Shearwave Elastography (SWE) ultrasound and blood biomarkers. SWE ultrasound uses high-frequency sound waves to view soft tissues such as muscles and internal organs and measure stiffness. An ultrasound creates computer images that show internal body organs, such as the liver or kidneys, more clearly than regular x-ray images. Biomarkers are biological molecules found in the blood that provide important information about liver disease.
