Filter by:In this study, adult Indonesian subjects with human immunodeficiency virus (HIV) coinfected with chronic hepatitis C (CHC) will be given peginterferon alfa-2b (PEG-IFN) plus ribavirin (RBV) combination therapy. The efficacy rate (sustained virologic response, end of treatment virologic response, and sustained biochemical response), the subject morbidity rate as caused by other opportunistic infection (eg, bacterial pneumonia, tuberculosis, and other bacterial infection), and the safety and tolerability of this combination therapy will be examined.
The objective of this study is to compare the efficacy of peginterferon alfa-2b (PegIFN-2b) monotherapy administered at a dose of 0.5 ug/kg vs stronger neo minophagen C (SNMC) in participants with chronic hepatitis C (CHC) and liver fibrosis (Metavir fibrosis score of F2 and F3) who were previously treated with interferon. The trial will evaluate the effect of treatment on the progression of liver fibrosis, liver inflammation, and liver function. Treatment will be administered for up to 156 weeks with a 4-week follow-up.
The purpose of this study is to assess the ability of eltrombopag to elevate platelet counts thereby reducing the need for platelet transfusions in chronic liver disease patients with thrombocytopenia undergoing elective invasive procedures. The clinical benefit of eltrombopag will be measured by the proportion of subjects who avoid platelet transfusions, before, during and up to 7 days after undergoing an invasive procedure. In addition, bleeding events will be monitored during this time. The number of transfusions, safety events and medical resource utilisation will be monitored during this time and for up to 30 days after undergoing an invasive procedure to help further evaluate clinical benefit.
Optimal ribavirin dosages are essential in achieving SVR (sustained virological response). Several studies have shown higher SVR rates in patients receiving higher doses of ribavirin. Therefore we propose a randomized controlled open label multicenter trial to investigate wether high (25-29mg/kg) dose ribavirin can improve outcome in patients in infected with hepatitis C virus genotype 1 or 4 compared to standard dose (12-15mg/kg).
To evaluate the efficacy of pegylated interferon alfa-2a 40 kD (PEGASYS) combination therapy with ribavirin (Copegus)given for 24 or 48 weeks in patients with chronic hepatitis C (CHC) virus infection genotype 2 or 3 who responded during (i.e. had HCV-RNA <50 IU/mL at the end of previous therapy), but relapsed after (i.e. had detectable HCV-RNA after the end of prior treatment) previous therapy with pegylated interferon and ribavirin given for at least 12 weeks and at most 24 weeks.
An open-label, multi-center, prospective, randomized study to evaluate the efficacy, safety and tolerability of LCP-Tacro tablets given once daily vs. azathioprine, each in combination with prednisone, for the treatment of autoimmune hepatitis (AIH).
The purpose of this clinical research study is to find out whether a combination of entecavir (ETV) plus tenofovir (TNF) works better against Hepatitis B virus than adefovir (ADV) added to continuing lamivudine (LVD) therapy in patients whose Hepatitis B virus (HBV) is resistant against lamivudine. The safety of this treatment will also be studied.
This study will assess the efficacy of everolimus as an inhibitor of fibrosis progression in liver transplant patients who have a recurrence of hepatitis C viral infection in the transplant
This study will test whether the combination of two medications, tenofovir and emtricitabine, are safer and more effective for treating chronic hepatitis B than tenofovir alone. Chronic hepatitis B is a liver disease caused by infection with the hepatitis B virus. Several medications, including standard and pegylated interferon and the anti-viral drugs lamivudine, adefovir, entecavir and telbivudine, are currently used to treat the disease. Problems are associated with all of these agents, however, including development of viral resistance with long-term therapy of the anti-virals. Since many patients require long-term therapy to prevent their disease from worsening, a major goal of new approaches to treatment is to prevent the development of viral resistance. Combination treatment has been shown to be an effective strategy in preventing this resistance. Tenofovir is an anti-viral drug approved for use in patients with HIV infection. In small studies in patients infected with both HIV and hepatitis B, tenofovir lowered the level of hepatitis B virus in the blood, with no viral resistance reported when used for up to 5 years. Emtricitabine is an anti-viral drug similar to lamivudine and is effective at lowering viral load and improving liver damage. Patients 18 years of age and older with chronic hepatitis B may be eligible for this study. Participants are admitted to the NIH Clinical Center for a complete medical history and examination, including blood and urine tests, chest X-ray, electrocardiogram, abdominal ultrasound, Fibroscan (ultrasound exam of the liver that measures the amount of scarring), bone mineral density scan and liver biopsy. They are then randomly assigned to take combination treatment with tenofovir plus emtricitabine or tenofovir alone for at least 48 weeks. During the treatment period, patients visit the Clinical Center for blood tests and a physical examination every 2 weeks for the first month and then every 4 to 12 weeks. After 48 weeks, patients are readmitted to the Clinical Center for a complete evaluation that includes all the tests done at the start of therapy, including a liver biopsy. Patients who seem to have improved with treatment may continue therapy for up to 192 weeks, when they are again admitted to the Clinical Center for a complete medical evaluation and liver biopsy. Patients whose condition has not improved after 48 weeks of treatment have their treatment changed or stopped and continue to have regular outpatient clinic visits for 24 more weeks.
The purpose of this study is to find out if a new investigational hepatitis B virus (HBV) vaccine, HEPLISAV™, is safe and effective for end-stage renal disease (ESRD) patients. Two dose levels will be studied: a single dose and a double dose. We expect both dose levels to safely immunize patients against HBV. The study will determine which dose does this best.
