Active clinical trials for "Hepatitis D"

Two LNF-containing regimens will be evaluated in the D-LIVR Phase 3 study: (1) LNF/RTV/PEG IFN-alfa-2a and (2) LNF/RTV. Each of these arms will have efficacy endpoints that measure clinical benefit with regard to viral suppression and alanine aminotransferase (ALT) normalization. For each LNF-containing regimen, a composite endpoint of EOT (48 weeks) virologic response and ALT normalization will be used. Virologic response will be defined as a 2 log10 IU/mL reduction from baseline.

The goal of this observational study is to evaluate the effectiveness of the carnitine-orotate complex and biphenyl dimethyl dicarboxylate in the adjuvant therapy of chronic hepatitis D in real clinical practice: a prospective cohort study

This study will evaluate the safety and effectiveness of a long-acting form of alpha interferon called pegylated interferon in treating hepatitis D virus (HDV) infection. HDV only infects people who already have hepatitis B infection. HDV is often severe and progressive. Alpha interferon is the standard treatment for HDV, given by injection once a day or three times a week for up to 12 months. However, this treatment does not work for everyone, and those who respond usually relapse when the drug is stopped. The sustained-release form of the drug, pegylated interferon, is given just once a week. Pegylated interferon is more effective than standard interferon in hepatitis C patients, with patients experiencing longer-term improvement. This study will evaluate the effects of pegylated interferon on hepatitis D and hepatitis B. It will determine whether long-term therapy with this drug improves inflammation and scarring of the liver, thereby delaying or reversing cirrhosis, and whether the improvement can be maintained. Patients with chronic hepatitis D over 6 years old may be eligible for this study. Participants will have a medical evaluation, including a history and physical examination, blood tests, routine urinalysis and 24-hour urine collection. Chest X-ray, electrocardiogram, abdominal ultrasound and liver biopsy will be done if these tests have not been done within the last year. In addition, depending on their age and individual health status, some patients may have exercise stress testing, an eye examination, hearing test, and psychiatric consultation. All patients will fill out a health-related quality of life questionnaire. Patients will receive pegylated interferon by injection once a week and have blood tests to measure the effects of treatment on the liver and on HBV and HDV levels. The medical examination and liver biopsy will be repeated at the end of 12 months. Patients who improved with treatment may continue therapy long-term. Medical evaluations and liver biopsies will be repeated at 3 years and at 5 years.

Background: Infection with hepatitis D virus leads to a chronic liver disease with no effective treatment. Lonafarnib has improved hepatitis D virus levels in blood, but the medication still needs more research. Ritonavir makes other drugs more effective and is used with lonafarnib to make it more effective. Lambda interferon stimulates the body s response to viruses. Researchers want to see if combining these drugs fights hepatitis D and helps the liver. Objectives: To see if combining lonafarnib, ritonavir, and lambda interferon is safe and effective to treat chronic hepatitis D infection. Eligibility: Adults at least 18 years old with chronic hepatitis D infection Design: Participants will be screened with a physical exam, medical history, and blood and urine tests. Throughout the study, all participants will: Follow rules for medicine, food, and contraception Take hepatitis B medicine Have weight checked Have routine blood and urine tests Give stool samples Female participants will have pregnancy tests. Participants will have 3 visits before treatment. They will repeat screening tests and have a heart test and liver scan. Participants will have a 5-day inpatient stay. They will: Baseline blood and urine tests Have eye tests Answer health questions Have a liver sample taken and liver blood pressure measured. Participants will be sedated. Have reproductive tests Start the study drugs and have blood draws Over 24 weeks of treatment, participants will: -Take 2 study drugs by mouth every day and 1 as a weekly injection

This is a multicenter, open-label, randomized clinical trial to Assess Efficacy and Safety of 3 Doses of Myrcludex B for 24 Weeks in Combination with Tenofovir Compared to Tenofovir Alone to Suppress HBV Replication in Patients with Chronic Hepatitis D

Development of preclinical translational models for chronic liver tumors and diseases study, such as spheroids cultured in autologous medium and murine xenograft models to test the efficacy of new therapeutic strategies.

Background: - Chronic hepatitis D is a liver disease caused by the hepatitis D virus (HDV). It can be severe and progressive. Most people with hepatitis D will develop scarring and damage to the liver. There is no FDA approved drug to treat chronic hepatitis D. Researchers want to know if the drugs lonafarnib and ritonavir can help people with chronic hepatitis D. Objective: - To find out if treatment of hepatitis D with lonafarnib and ritonavir is safe and effective. Eligibility: - People 18 years of age and older with chronic hepatitis D. They must not have HIV or other major illnesses. Design: Participants will be screened with medical history, physical exams, and blood tests. Participants will have 24 weeks of treatment. They will then have 24 weeks of follow-up. Participants will be in 1 of 6 treatment groups. Those in each group will receive different doses of the study drugs. Some groups will start with placebo but will receive treatment after 3 months of placebo. Participants will also take drugs to treat hepatitis B. Participants will have many visits. These will include: One three-day stay at the Clinical Center Physical exams EKG: small sticky patches will be put on the chest, arms, and legs to trace heart rhythm Ultrasounds of the abdomen Urine and blood tests Stool samples Eye exams Evaluations by a reproductive endocrinologist (women) or urologist (men). Men may provide a sperm sample (optional).

To evaluate safety and tolerability of lambda over a 48-week treatment period in HDV patients.

Chronic hepatitis B is a disease of the liver caused by the hepatitis B virus. It affects nearly 1 million Americans. Approximately 25% of patients with chronic hepatitis B will develop liver cirrhosis and 5% of patients will develop liver cancer. Presently, two medications have been shown effective in the treatment of hepatitis B: lamivudine and alpha interferon. Alpha interferon (an antiviral drug that acts through the immune system) is given by injection once daily or three times a week for four to six months. Lamivudine (also known as 3-thiacytidine: 3TC) is an antiviral medication given as a pill once a day for twelve months. These treatments have been known to provide long-term improvement in one third of patients receiving them. In previous research, the drug lamivudine was shown to stop the growth of the hepatitis B virus and to lead marked decreases in the levels of hepatitis B virus and to improvements in the disease in 50 to 70% of patients. However, once lamivudine therapy was discontinued the virus returned to levels noted before the therapy began. In those studies lamivudine was given for 3 to 12 months then discontinued. This study will investigate the safety and effectiveness of long-term therapy with lamivudine. This study will select 60 patients diagnosed with hepatitis B. After a thorough medical examination and liver biopsy, subjects will be given lamivudine. The drug will be taken by mouth in tablet form (100 mg) once a day for up to 5 years. Subjects will undergo regular check-ups and after 1 year of therapy be admitted to the Clinical Center for another medical examination and liver biopsy to assess progress. Patients who have benefitted from the therapy will continue taking the medication for up to 5 years. A third liver biopsy will be done during the last year of treatment. The effectiveness of lamivudine will be determined by whether levels of hepatitis B virus decrease in the blood, whether liver enzymes improve, and whether inflammation and scarring decreases in the liver biopsies.
