7 Clinical Trials for Various Conditions
The Phase 3 LIMT-2 study will evaluate the safety and efficacy of Peginterferon Lambda treatment for 48 weeks with 24 weeks follow-up compared to no treatment for 12 weeks in patients chronically infected with HDV. The primary analysis will compare the proportion of patients with HDV RNA \< LLOQ at the 24-week post-treatment visit in the Peginterferon Lambda treatment group vs the proportion of patients with HDV RNA \< LLOQ at the Week 12 visit in the no-treatment comparator group.
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.
This is a Phase 2b/3 study designed to evaluate the safety and efficacy of chronic treatment with brelovitug (a.k.a BJT-778; BTG) for chronic hepatitis delta virus (HDV) infection. The comparator in this study will be 24-weeks of delayed treatment. During the 24-weeks of delayed treatment, participants will complete the same visits and assessments as those randomized to initiate brelovitug immediately. At the completion of 24-week delayed treatment period, all participants will start treatment with brelovitug.
This is a multicenter, open label, randomized Phase 3 clinical study to evaluate the efficacy and safety of the combination of tobevibart + elebsiran for the treatment of chronic hepatitis delta in comparison to delayed treatment.
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
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).
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.
