NCT00356564
Persistence of seroprotective antibody concentrations \& immunological memory shown by the ability to mount a response to a challenge dose of HBV vaccine
NCT01464008
The efficacy of combination antiviral therapy for chronic hepatitis C is influenced by many factors. Important patient-specific factors include, age, gender, race, body weight. Important virus-specific factors include HCV genotype and serum HCV RNA level. Finally, important treatment-related factors include the type of interferon, dose of ribavirin and the duration and adherence to treatment. Despite the importance of patient- and virus-specific factors, the most important indicator of treatment success is a rapid, profound and sustained decrease in serum HCV RNA levels after the start of treatment. The on-treatment virological response can thus be used to predict the probability that a given patient will achieve an SVR if they remain on therapy. It can also be used to individualize the duration of treatment. In this study, treatment for patients with chronic hepatitis C was individualized on the basis of clinical characteristics and the on-treatment virological response. The aim was to investigate the usefulness of undetectable HCV RNA levels at week 4 (RVR) and 12 in tailoring the duration of treatment and predicting SVR in Chinese patients with chronic hepatitis C.
NCT00290303
The purpose of this study is to compare the immune response, safety and reactogenicity of Tritanrix™-HepB/Hib-MenAC vaccine given either with or without a birth dose of hepatitis B vaccine to Tritanrix™-HepB/Hiberix™ when given to healthy infants (born to mothers who do not carry hepatitis B virus) at 6, 10 \& 14 weeks of age. This study will also include a small group of infants born to mothers who do carry hepatitis B virus; these infants will receive a birth dose of hepatitis B vaccine and will be vaccinated with Tritanrix™ HepB/Hib-MenAC at 6, 10 \& 14 weeks age.
NCT00366366
This study assessed the immunogenicity and safety of two vaccination regimens that employed either GSK Biologicals' combined DTPa-HBV-IPV/Hib vaccine or DTPa-IPV/Hib vaccine. In the two groups, infants received the DTPa-IPV/Hib vaccine at 3 and 4 months of age, as the first 2 doses of the primary vaccination course. At 5 months of age, they received either the DTPa-IPV/Hib vaccine co-administered with the HBV vaccine or a dose of the DTPa-HBV-IPV/Hib vaccine as a 3rd dose. Infants in the two groups had previously received 2 doses of HBV vaccine at birth and at 1 month of age.
NCT00383227
Comparison of adjuvanted hepatitis B vaccine to double dose of Engerix™-B in pre- /haemodialysis patients aged ≥15 years
NCT01798576
This prospective, national, multicenter, observational study will evaluate in routine clinical practice the efficacy and safety of re-treatment with Pegasys (peginterferon alfa-2a) plus ribavirin or regimens containing direct-acting antivirals in participants with chronic hepatitis C who failed previous treatment. Participants will be followed for the duration of their treatment (24, 48 or 72 weeks) and for 24 weeks of follow-up.
NCT01878799
Background: \- Present treatment for hepatitis C includes the use of a weekly injection and two different pills. This treatment is associated with serious side effects. Drugs that can be taken by mouth and cure HCV infection without serious side effects would be a great help to the large number of people infected with HCV. GS-7977 and GS-5885 are new medications being developed to treat the hepatitis C virus (HCV) infection. They are still being researched and are not approved by the Food and Drug Administration. They are being developed as treatment for hepatitis C as a single pill taken once a day. Objectives: \- To determine whether a combination of the two study drugs can safely and effectively treat HCV infection in people with HIV infection and who do not have cirrhosis of the liver. Eligibility: \- Individuals who have HIV infection and have liver disease caused by infection with HCV. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. Urine samples will be collected from participants who might become pregnant. If a participant has not had a liver biopsy in the past 3 years, one will be required. * Participants will take one pill daily for 12 weeks. This pill will be a combination of the two study drugs. * Treatment will be monitored with frequent clinic visits and blood tests over a total of 60 weeks.
NCT02898922
Background Hepatitis B virus (HBV) co-infection in individuals with hepatitis C virus (HCV) can enhance the severity of hepatitis and the risks of liver cirrhosis and hepatocellular carcinoma (HCC). Hepatitis B vaccine is an effective measure to prevent HBV infection. Whether patients with HCV infection have non-protective antibody responses to hepatitis B vaccination more frequently than healthy subjects is still controversial and studies about cytokine response have been seldom reported. Methods Not-in-treatment patients with chronic HCV infection and 1:2 community/gender matched healthy control were obtained from a community-based screening. All participants received three doses of hepatitis B vaccine (20 μg HBsAg/ml/dose) on 0, 1 and 6 months schedule. Anti-HBs was tested 1 month after the third dose of vaccination and was compared between two groups. Spot-forming cells (SFCs) of interferon-γ (IFN-γ), interleukin-2 (IL-2), interleukin-4 (IL-4), interleukin-5 (IL-5) and interleukin-6 (IL-6) produced by lymphocyte were tested by enzyme-linked immunospot (ELISPOT) and were compared between two groups.
NCT01962155
The aim of our prospective study is to construct and validate a non-invasive model consisting biochemical markers, FibroScan, and radiological parameters for evaluating liver fibrosis caused by hepatitis B virus in mainland China.
NCT00880477
This study will assess the immunogenicity, safety and reactogenicity of GSK Biological's DTPa-HBV-IPV/ Hib vaccine as compared to GSK's DTPa-IPV/Hib vaccine co-administered with HBV according to a three-dose immunisation course and as a booster dose in infants born to hepatitis B antigen seronegative mothers and previously primed with a birth dose of GSK's HBV vaccine.
NCT01358864
The aim of this trial is to evaluate the efficacy and the safety of BI 201335 given for 12 or 24 weeks in combination with PegIFN/RBV given for 48 weeks as compared to PegIFN/RBV alone in chronic GT-1 hepatitis C virus infected patients who failed a prior PegIFN/RBV treatment.
NCT02732639
This study evaluated the efficacy and safety of 48-week treatment with pegylated interferon (PEG-IFN) alfa-2a (Pegasys) monotherapy in participants with chronic hepatitis D (CHD). Treatment was followed by 24 weeks of treatment-free follow-up.
NCT02716779
This study examined the influence of ribavirin on the initial virological response in treatment-naïve participants with chronic hepatitis C, genotype 1. Participants were randomized to 1 of 3 treatment groups to receive placebo, ribavirin monotherapy 1000 milligrams (mg) to 1200 mg orally daily depending on body weight or pegylated interferon (PEG-IFN) alfa-2a (Pegasys®) 180 micrograms (mcg) subcutaneously (SC) weekly, for 6 weeks. Following the initial 6 weeks, all participants received combination therapy with PEG-IFN alfa-2a plus ribavirin (Copegus®) for 12 weeks. If there was an initial virological response after 12 weeks of combination therapy, treatment could be continued for a further 36 weeks outside of the study.
NCT02368288
The aim of interferon therapy in HBeAg positive chronic hepatitis B was to make patients obtain immune control to hepatitis B virus defined as occurred HBeAg seroconversion and HBsAg loss with sustained viral response after treatment. However this target could not be get if patients keep HBV DNA positive during interferon treatment and offend relapse after withdraw of treatment. In this trail, Nucleoside(acid) analogues(NA) will add on patients with HBV DNA load ≥1000copies/ml after 6 months of interferon treatment, and the efficacies of the combine therapy were evaluated by the rates of HBeAg seroconversion and HBsAg loss after 48 weeks of combined therapy, compared with control group.
NCT01480284
The purpose of this study is to evaluate the efficacy and safety of GSK548470 administered once daily at a dose level of 300 mg to Japanese patients with compensated chronic hepatitis B untreated with any nucleic acid analogue. In efficacy, the non-inferiority of GSK548470 to ETV will be verified using the antiviral effect as the index.
