Filter by:1. Evaluate the safety, tolerability, and virologic activity of escalating single (and multiple) doses of XTL6865, a mixture (1:1) of two human monoclonal antibodies (HCV-AbXTL68 and HCV-AbXTL65), in patients with chronic hepatitis C virus infection. 2. Assess the pharmacokinetics of XTL6865 in the presence and absence of viral infection.
Open-label studies, anecdotal reports, and in vitro scientific research indicate that 4-methylumbelliferone (active ingredient of the dietary supplement Heparvit®) may prevent and reverse the symptoms and complications of chronic infection with hepatitis B virus (HBV)and hepatitis C virus (HCV). This effect has been observed among naïve patients as well as those who are non-responders to interferon, commonly used as first-line therapy for HBV and HCV. In order to scientifically address the efficacy of this 4-methylumbelliferone on chronic viral hepatitis, a randomized, placebo-controlled, blinded study is needed. It is hypothesized that 4-methylumbelliferone may reduce the impact and aggressiveness of HBV and HCV upon the liver, thereby slowing the progression to potentially life threatening liver diseases such as cancer and cirrhosis. This is a preliminary study designed to determine any indications under controlled conditions that may warrant further detailed clinical studies.
Objectives: Primary To evaluate the safety, tolerability, and efficacy of Peginterferon a-2a plus Ribavirin for the treatment of chronic hepatitis C (CHC) infection in persons co-infected with human immunodeficiency virus (HIV) who have failed to achieve a sustained virologic response following previous interferon therapy. Secondary - To evaluate the virological response to Peginterferon a-2a plus Ribavirin at weeks 12 and 24 as compared to baseline values. - To evaluate the sustained virological response Peginterferon a-2a plus Ribavirin at post-treatment weeks 4, 12, and 24 as compared to baseline. - To evaluate the histological effects of long-term Peginterferon a-2a therapy through comparison of liver biopsy results following 96 weeks of Peginterferon a-2a therapy to baseline values. - To evaluate the safety and tolerability of long-term Peginterferon a-2a therapy in patients who have previously failed to achieve a sustained virologic response following interferon therapy. - To investigate the effects of long-term Peginterferon a-2a therapy on clinical outcomes of HIV disease. Study Design: All qualifying patients will enter the treatment phase and be dosed as follows: Peginterferon a-2a 180mg by subcutaneous route once weekly plus Ribavirin: - 800 mg (400 mg bid) if body weight < 65 kg - 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg - 1200 mg (600 mg bid) if body weight > 85 kg Patients with undetectable levels of HCV-RNA at Treatment Week 24 will continue on previously assigned Peginterferon a-2a plus Ribavirin combo-therapy for an additional 24 weeks. Patients with detectable levels of HCV-RNA will be randomized to Peginterferon a-2a mono-therapy or no treatment for 72 weeks. - Group A: Peginterferon a-2a 90mg mono-therapy for 72 weeks. - Group B: No CHC therapy for 72 weeks All patients entering the study are required to have a baseline liver biopsy (within 18 months of study entry). Patients entering the 72-week randomized arm of the trial will have a post-study liver biopsy upon completion of the trial. Study Population: 100 HIV infected adults with chronic hepatitis C infection who have failed to achieve a sustained virologic response following previous interferon therapy. Dosage and Administration: Combo-therapy: Peginterferon a-2a 180mg by subcutaneous route once weekly plus Ribavirin: - 800 mg (400 mg bid) if body weight < 65 kg - 1000 mg (400 mg a.m. and 600 mg p.m.) if body weight > 65 kg and < 85 kg - 1200 mg (600 mg bid) if body weight > 85 kg Mono-therapy: Peginterferon a-2a 90mg in 1mL solution administered subcutaneously once weekly. Efficacy Evaluations: Laboratory analysis, liver biopsies, quality of life assessments, and changes in Peginterferona-2a and Ribavirin dosages will be obtained. Safety Evaluations: - Assessment of laboratory evaluations - vital signs - incidence and severity of adverse experiences - dose adjustments - premature withdrawal for safety reasons - progression of disease as measured by HCV viral load - AIDS defining events
The purpose of this study is to compare three treatment regimens in patients who have received a liver transplant for end-stage liver disease caused by Chronic Hepatitis C infection.
This study is designed to evaluate the safety and antiviral activity of tenofovir disoproxil fumarate (TDF, tenofovir DF) compared to adefovir dipivoxil (ADV) for the treatment of HBeAg-positive chronic hepatitis B. Participants will receive either TDF or the approved hepatitis B therapy ADV. After 48 weeks all participants will be switched to open-label TDF.
