Active clinical trials for "Hepatitis D"

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.

Background: Chronic hepatitis D is a severe disease of the liver caused by infection with the hepatitis D virus. The hepatitis D virus can only infect a person who also has hepatitis B; therefore, people with delta hepatitis have both hepatitis B and hepatitis D virus infection. Most people with hepatitis D eventually develop cirrhosis, which causes scarring and damage to the liver. There is currently no effective treatment for chronic hepatitis D. Lonafarnib is a drug that was originally designed to treat different types of cancer. It may be able to prevent the hepatitis D virus from reproducing itself. However, it has not been tested on people with hepatitis D. Researchers want to study different doses of lonafarnib to see how they affect virus levels and other symptoms of hepatitis D. Objectives: - To test the safety and effectiveness of lonafarnib as a treatment for chronic hepatitis D. Eligibility: - Individuals at least 18 years of age who have chronic hepatitis D. Design: Participants will be screened with a medical history and physical exam. They will have blood and urine tests, eye exams, and imaging studies of the liver and gall bladder. A liver biopsy may also be performed. Participants will receive either lonafarnib or placebo twice a day for 28 days. For the first 3 days, participants will stay in the hospital to have frequent blood tests. Participants will have four more clinic visits (on days 7, 14, 21, and 28) for blood and urine tests. Eye exams and heart function tests will also be given. Men may be asked to provide sperm samples for further testing. After the 28 days of treatment, participants will stop taking the drug or placebo. They will have regular followup visits for up to 6 months after stopping treatment....

The primary objective of this study is to evaluate the efficacy of bulevirtide combination with pegylated interferon in participants with chronic hepatitis delta (CHD).

This is a retrospective, prospective, noninterventive, multicenter registry study. Patients diagnosed with HDV infection (based on positive HDV RNA) were included in this study and were followed up for at least 5 years to evaluate their disease progression and clinical outcomes (including death, liver transplantation, hepatocellular carcinoma [hcc], liver decompensation, and cirrhosis) during the 5-year follow-up period. All patients were followed up at least once a year after they were included in the study. It was in 2016 HDV infection first reported in China. Since January 1, 2016, all patients diagnosed with HDV infection can be enrolled in this study and evidence confirming the diagnosis (including but not limited to HDV RNA test reports and medical records, etc.) must be delivered. The main test results (including serum HDV RNA, ALT, and tests to determine the presence of liver cirrhosis, decompensation of liver function, and liver cancer such as B-ultrasound and FibroScan) of these patients each year from diagnosis to enrollment should be collected and filled in the case report form (CRF). Follow-up data of patients with serum anti-HDV positive and HDV RNA negative can be recorded and followed up on this platform, with informed consent of the patients is required. Patients whose serum HBV RNA turn positive during the follow-up period will be included in the follow-up cohort of the study.

This single-center, randomized, open-label, pilot study is designed to evaluate the efficacy and safety of 48 weeks of treatment with peginterferon alfa-2a alone versus in combination with ribavirin in participants with CHD.

An Open-label, Dose-ranging Study to Evaluate the Safety and Efficacy of Lonafarnib with Ritonavir Boosting +/- Peginterferon alfa-2a in Patients Chronically Infected with Delta Hepatitis (HDV) (LOWR-2).

This randomized, single blind study will compare the antiviral effect of Pegasys (pegylated interferon alfa-2a) plus placebo versus Pegasys plus tenofovir in patients with chronic hepatitis D. Patients will be randomized to receive 96 weeks of therapy with Pegasys (180 micrograms sc weekly) plus either placebo (orally daily) or tenofovir (245mg orally daily). Anticipated time on study treatment is 2+ years, target sample size is <50.

The objective of this study is to determine the effectiveness of peginterferon alfa-2b 1.5 mcg/kg/week administered for 52 weeks (wk) in previously untreated participants coinfected with hepatitis virus B and D. After 52-week treatment and 52-week follow-up, the virologic, biochemical, and histological response will be evaluated.

Study is to Understand the pattern of hepatitis delta screening among medical providers for Asian patients with chronic hepatitis B Determine the proportion of Asian hepatitis B patients who have been screened and who have chronic hepatitis delta Determine the pattern of hepatitis delta screening after education of medical providers on hepatitis delta

Randomized, double blind study comparing the efficacy of pegylated interferon-alfa2a plus placebo versus pegylated interferon-alfa2a plus tenofovir for the treatment of chronic delta hepatitis. 70 Patients will be randomized 1:1 into the two groups. Treatment duration: 96 weeks. Follow-up: 24 weeks. Long-term-follow-up: until week 358.
