Active clinical trials for "Hepatitis, Chronic"

The purpose of this study is to evaluate the safety and efficacy of ABT-450, ritonavir and ABT-267 (ABT-450/r/ABT-267; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) co-administered with ribavirin (RBV) in hepatitis C virus genotype 1 infected treatment-experienced adults.

This dose-escalating study is to evaluate the efficacy and the safety of different doses of a new bio-product Pegylated Recombinant Consensus Interferon Variant Solution for Injection (PEG-IFN-SA) and Ribavirin（RBV） in the treatment of Chronic hepatitis C who have not been previously treated with Interferon(IFN) by exploring the dose-effect relationship, while identity the optimal dose for phase Ⅲ study. In addition, population pharmacokinetic method is adopted to assess the pharmacokinetic behavior, individuals / intra-individual variability, and the possible factors for further study.

This is a multicenter, double blind, active-controlled, randomized, parallel group study to demonstrate the anti-viral activity and safety of Baracle Tab. and Baraclude Tab. for patients with HBeAg Chronic Hepatitis B. The subject will receive two tablets daily for 48 days.

Background: - Chronic hepatitis C is a serious liver disease. Current treatments have side effects. New drugs have been developed, but they work better in some people than others. Researchers want to learn why. Objective: - To learn why new hepatitis C drugs sometimes do not work. Also, to learn if these drugs are safe and how well they work in people with different virus strains. Eligibility: - Adults age 18 and older who are infected with hepatitis C virus genotypes 1-4 and who have either never been treated or treated previously with an interferon regimen (with or without ribavirin) that failed to clear the virus. Design: Participants will be screened with medical history and physical exam. They will have blood and urine tests and complete questionnaires. Participants will have a Fibroscan, an ultrasound that measures liver stiffness and other liver scans. They will have an electrocardiogram. Eligible participants will have a liver biopsy. Participants will be admitted to the Clinical Center. They will have a physical exam and blood tests, and complete questionnaires. They will take the first study drug dose as a tablet taken once daily. Participants will take the drug at home for 12 weeks. Participants will have 6 study visits. They will have blood and vital signs taken, and complete questionnaires. At week 4, participants will have another liver biopsy. After their last drug dose, participants will have 5 follow-up visits. They will have blood and vital signs taken, and complete questionnaires. They will discuss their medications and side effects. They may have another Fibroscan.

This is a Phase 3, open-label, multicenter study evaluating the efficacy and safety of ABT-450/r/ ABT-267 and ABT-333 coadministered with RBV for 12 weeks in HCV genotype 1b, treatment naïve and Interferon (IFN) (alpha, beta or pegIFN) plus RBV treatment-experienced Asian adults with compensated cirrhosis.

This is a phase IV, single-arm, open-label, multi-centre study to assess the efficacy of TDF in Chronic hepatitis B (CHB) subjects following failure of multiple Nucleos(t)ide analogues (NAs). The study will enrol 200 CHB subjects following failure of multiple NAs. Subjects will be assessed for eligibility at a screening visit, with eligible subjects returning for a baseline assessment after approximately 4 weeks (Screening phase). In the treatment phase all enrolled subjects will receive open label TDF at a dose of 300 milligrams (mg) orally once daily. All the eligible study subjects will undergo safety and efficacy assessments every 12 weeks for a total of 14 visits. Tenofovir disoproxil fumarate, the oral pro-drug of tenofovir (TFV), is a nucleotide analogue that inhibits viral polymerases by direct binding and after incorporation into deoxyribonucleic acid (DNA), by termination of the DNA) chain. TDF is a highly potent treatment in treatment-naïve and lamivudine (LAM) resistant CHB patients. The purpose of our study is to evaluate the efficacy of TDF treatment in Chinese CHB patients following failure of multiple NAs. In addition, the study will also explore the relationship of baseline factors and early HBV DNA suppression to long-term virological response. The efficacy of TDF in multi-drug resistant patients will be analysed separately. The data generated by this study could then be used to optimize the clinical application of TDF and provide new evidence for management of the HBV infections following failure of multiple NAs. The result of this study will help Chinese physicians better manage the CHB patients following failure of multiple NAs.

The purpose of this study is to evaluate the safety and efficacy of Ombitasvir (OBV)/paritaprevir (PTV)/ritonavir (r) with sofosbuvir (SOF) with or without ribavirin (RBV) in adults with Genotype 2 Chronic Hepatitis C Virus (HCV) infection or Genotype 3 HCV infection with or without Cirrhosis.

This open-label study will evaluate the safety and efficacy of co-formulated ombitasvir/paritaprevir/ritonavir and dasabuvir co-administered with sofosbuvir with or without ribavirin administered for either 4 or 6 weeks in treatment naive adults with chronic HCV-genotype 1 infection without cirrhosis

This study will examine the effectiveness of 15 days of therapy with SCY-635 in reducing hepatitis C virus (HCV) RNA levels.

The purpose of the study was to determine safety and efficacy of 48 weeks treatment with Thymosin alpha 1 (Talpha1) in combination with pegylated interferon (PEGIFN) alpha2a and ribavirin (RBV) in adult patients with chronic hepatitis C (CHC) already treated with, and not responding to previous courses of PEGIFN alpha plus RBV combination therapy, in comparison with a concurrent group treated with PEG IFN alpha2a in combination with RBV and placebo.
