Filter by:The purpose of this study is to conduct a prospective, three-group study that randomly assigns 700 parolees, in a community residential drug treatment program, to enter one of three groups: 1) a PCPC (Parolee Comprehensive Care + Phone Coaching Program), which includes nurse case management and specialized hepatitis education sessions and the hepatitis A/B (HAV/HBV) vaccination series (to all eligible) and coach-facilitated mentoring (mostly by cell-phone); 2) a Parolee Brief Hepatitis Education + HBV vaccination + Phone Coaching (PBCP) Program, which includes brief hepatitis/HIV education, HAV/HBV vaccination and coach-facilitated mentoring; or 3) a Usual Care (UC) control program, which includes brief general health information, one-on-one coaching and the HAV/HBV vaccine.
A Phase 2 Study to Evaluate the Safety, Efficacy, Pharmacokinetics, and Pharmacodynamics of VX-135 and Daclatasvir in Treatment-Naïve Adult Subjects With Genotype 1 Chronic Hepatitis C
This study is to to evaluate the safety, tolerability, and efficacy of sofosbuvir (SOF) plus ribavirin (RBV) in Egyptian adults with genotype 4 hepatitis C virus (HCV) infection.
This safety surveillance study is being conducted in accordance with Korea Food and Drug Administration (KFDA) "Basic standard for reexamination of new drug". Primary objective: - To assess the safety of AVAXIM 160U (Hepatitis A vaccine) administered under the routine practice, according to Korea Food and Drug Administration "Basic standard for reexamination of new drug" based on the pharmaceutical law in Korea.
The purpose of this study is to measure intrahepatic HCV RNA levels at the time of liver transplantation in patients receiving antiviral therapy while on the liver transplant waiting list. This will eventually be correlated with the degree of hepatic fibrosis present within different geographic sites in the cirrhotic liver. Tissue samples will be obtained from the patient's liver explant as well as hilar lymph nodes. Upon the removal of the cirrhotic liver at the time of transplantation, the explant will be biopsied multiple times in different segments of the liver and preserved for viral detection studies as well as analysis of the degree of fibrosis. Peripheral blood mononuclear cells (PBMCs) will be obtained for viral detection at the time of transplantation. Serum HCV RNA levels will also be obtained at 1 month, 3 months and 6 months post liver transplantation. Study Hypotheses: - Virological relapse or non-response is higher is patients with cirrhosis due to failure of antiviral medication to concentrate adequately in a fibrotic liver having an altered sinusoidal micro-architecture - HCV may persist in different geographic regions of the fibrotic liver in part predicated on blood supply to that area and this may have an effect on overall virological response. These differences in viral persistence and detection may exist in different lobes of the liver or even within a few centimeters within the same portion of the liver parenchyma. - PBMC and hilar lymph nodes may be extrahepatic reservoirs of HCV viral persistence in patients receiving antiviral therapy and may account for virological relapse post-therapy - There may be varying degrees of fibrosis within the same cirrhotic liver which may impact on hepatic synthetic function and antiviral response to treatment.
Proof-of Concept, Open-Label, Two-Stage Study without Direct Individual Benefit The proposed study design consists of two treatment periods and one treatment arm. Treatment Period 1 involves the administration of RBV monotherapy for a period of 8 weeks and Treatment Period 2 involves administration of up to 16 weeks combination therapy with RBV plus HCQ.
Entecavir (ETV) has shown superior ability to suppress hepatitis B virus (HBV) replication, histology improvement as well as low rate of emergence of resistant mutants. Out of range of clinical recommendations for treatment of chronic hepatitis B (CHB), chronic HBV carriers with persistently normal ALT and viral load more than 10^5 copies/mL have progression of liver disease during long-term follow-up. In addition, certain proportions of these patients do have significant inflammation and fibrosis in liver histology. This study will be able to identify who are at risk of liver disease progression and evaluate efficacy of ETV regarding improvement of liver histology during short-term (1-year) and long-term ETV treatment (3-year).
The purpose of this study is to evaluate the safety and antiviral activity of ABT-450/ritonavir/ABT- 267 (ABT-450/r/ABT-267; ABT-450 also known as paritaprevir; ABT-267 also known as ombitasvir) and ABT-333 (also known as dasabuvir) with and without ribavirin (RBV) in patients with chronic hepatitis C virus genotype 1a (HCV GT1a) infection without cirrhosis.
This study aims to demonstrate that patients with chronic hepatitis C (CHC) and B (CHB) experiencing regression of liver cirrhosis after effective antiviral therapy have decreased risk for hepatocellular carcinoma (HCC). Primary aim is to determine the incidence of HCC in patients with cirrhosis secondary to CHC and CHB, after treatment is provided, and to identify the magnitude of the decreased risk for HCC in patients experiencing regression of fibrosis. As a secondary aim, environmental risk factors for HCC development will be sought, in order to determine a subset of patients in whom it will be safe to stop surveillance.
To assess the pharmacokenetic characteristics of 600 mg BID BI 207127 / 120 mg QD faldaprevir /ribavirin in a small number of GT1b HCV infected patients with mild hepatic impairment (CPA) (Arm 1) versus 400 mg BID BI 207127 / 120 mg QD faldaprevir /ribavirin in a small number of GT1b HCV infected patients with moderate hepatic impairment (CPB) (Arm 2).
