Filter by:The purpose of this research trial is to find out whether NOV-205 is well tolerated compared to placebo (salt water) in people with hepatitis C. In addition, this trial will test how NOV-205 is absorbed by your body after single and multiple doses of the trial drug, and it will look for early signs of therapeutic activity (decreases in indicators in the blood for the hepatitis C virus and for liver damage). This is known as pharmacokinetics (PK). NOV-205 is an experimental drug. "Experimental" means that the trial drug is currently being tested and is not approved for sale in the United States by the Food and Drug Administration (FDA). However, NOV-205 has been approved by the Russian Federation for treatment of liver diseases including hepatitis C. Clinical studies in that country showed that subjects treated with NOV-205 alone had decreased indicators in the blood for the hepatitis C virus and for liver damage.
Compare the effectiveness of telaprevir (VX-950) in combination with Pegylated Interferon Alfa 2a (Peg-IFN-alfa-2a) with and without Ribavirin (RBV) in reducing plasma hepatitis C virus (HCV) ribonucleic acid (RNA) levels
This is an open label, randomized, comparative, multi-center study. Subjects will be screened within 2 weeks prior to study entry to establish eligibility. Subjects who meet all the selection criteria will be randomly assigned 1:1 to (1) once-a-week, subcutaneous Pegylated interferon alfa-2b (PegIntron) (1.5 mcg/kg body weight) or (2) oral adefovir 10 mg daily. The treatment phase will be 24 weeks for PegIntron and 48 weeks for adefovir. All subjects completing the assigned treatment phase will be followed up for an additional 48 weeks for PegIntron and 24 weeks for adefovir as observation phase. The primary objective is to establish the efficacy profile of PegIntron. Secondary objectives are to compare the efficacy profile of PegIntron with that of adefovir, compare efficacy of PegIntron in lamivudine-naïve and lamivudine-experienced subjects, and to establish the safety profile of PegIntron in treating patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B.
The purpose of this clinical research study is to develop observational clinical experience with the use of entecavir in participants who are either of Black/African-American race or of Hispanic ethnicity.
This study will explore why severe scarring of the liver (cirrhosis) develops so rapidly in hepatitis C-infected patients who have had a liver transplant and possibly in kidney transplant patients as well. The hepatitis C virus (HCV) can cause cirrhosis in about 20 percent of infected persons. Generally, it takes 20 years or more for cirrhosis to develop. After liver transplantation, however, patients may develop cirrhosis in as little as 5 years. Cirrhosis does not develop as rapidly in kidney transplant patients, but it may develop faster than in people who do not undergo transplantation. The study will look at the possible role of immune-suppressing medications given to liver and kidney transplant patients in increasing the severity of hepatitis C infection and in speeding the cirrhotic process. Patients 18 years of age and older with chronic HCV infection who require a liver transplant for end-stage liver disease or a kidney transplant for kidney failure may be eligible for this study. Liver transplant patients are recruited from the Inova Fairfax Liver Transplant Center in Fairfax, Virginia, and from the Georgetown University Medical Center Liver Transplant Institute in Washington, D.C. Kidney transplant patients are recruited from the Transplantation Branch of the National Institute of Diabetes and Digestive and Kidney Diseases. Participants undergo the following procedures: - Regular care: As part of their regular transplant-related treatment, patients have a medical history, physical examinations and blood draws before their transplant and on regularly scheduled visits after the transplant. - Blood draws for research: Special blood tests are done to measure the immune response to HCV. They measure the amount of HCV in the blood, the number of HCV strains present and how they change over time and the HCV antibodies in the blood. - Liver biopsies: This procedure is done at 3 months, 1 year, 3 years and 5 years after the transplant to determine the extent of scarring of the liver and to study the immune responses within the liver, the proportion of liver cells infected with HCV and the presence of scar-producing cells. The biopsy is done during a 1- to 2-day inpatient hospital stay. The patients are given a sedative medication through a vein before the procedure. The skin over the biopsy site is numbed and the biopsy needle is passed rapidly into and out of the liver to collect a small sample of liver tissue for study. - Apheresis: This procedure is done to collect a large number of white blood cells needed to test the immune response to the HCV. On the day before each liver biopsy, blood is drawn through a needle from a vein in one arm and run through a machine that separates and collects the white cells. The red cells and plasma are returned to the patient's body through the same needle or a second needle in the other arm.
This is a phase 2, randomized, open-label study comparing the safety, antiviral activity, and pharmacokinetics of HCV-796 administered in combination with peginterferon alfa 2B (Peg-Intron) plus concomitant Rebetol vs. Peg-Intron plus Rebetol in Hepatitis C Virus (HCV) genotype 1-infected subjects who are either naive to treatment or who have previously failed treatment (non-responders).
The purpose of this trial is to determine the safety, tolerability and effectiveness of KRN7000 for chronic hepatitis B infection.
The purpose of this study is to evaluate the durability of antiviral activity in chronic hepatitis B patients who showed complete response in L-FMAU-301,L-FMAU-302 or L-FMAU-303 trial.
The purpose of this study is to compare the efficacy and safety of 48-week treatment with Clevudine 30 mg qd versus lamivudine 100 mg qd for chronic hepatitis B infection.
PR5I, a hexavalent pediatric combination vaccine is being developed to reduce the number of injections during the first 2 years of life while providing a complete course of immunization against infection caused by H. influenzae type b, hepatitis B virus, Corynebacterium diphtheriae, Clostridium tetani, Bordetella pertussis, and poliovirus types 1, 2, and 3. Primary Objective: To evaluate immunogenicity of PR5I with the adjuvant composition enhancement to the hepatitis B component when administered concomitantly with Prevnar® Secondary Objectives: To assess the safety and immunogenicity of PR5I when administered concomitantly, or one month apart with Prevnar® or separately with licensed vaccines used for routine infant vaccination in Canada.
