Chronic Hepatitis Delta clinical trials

Peginterferon Lambda and Lonafarnib Boosted With Ritonavir 48-Week Combination Therapy for Delta Hepatitis

Background: Chronic hepatitis D is a serious liver disease caused by a virus. Currently, no medications are approved to treat chronic hepatitis D. Objective: To test a combination of 3 drugs in people with chronic hepatitis D. Eligibility: People 18 years or older with chronic hepatitis D. Design: Participants will be in the study about 2 years. They will have 3 inpatient stays of 3 to 5 days. Participants will be screened. They will have a physical exam with blood tests. They will have a test of their heart function and an ultrasound: a wand that uses sound waves to create images of the liver will be rubbed over the skin on their torso. Participants will stay in the clinic for a 3-day baseline visit. They will have imaging scans, an eye exam, and a visit with a reproductive specialist. They will have a liver biopsy: about 1 inch of liver tissue will be removed, either with a tube inserted through a vein in the neck, or with a needle inserted through the participant s side. Participants will take the study drugs for 48 weeks. Two of them are tablets taken twice a day at home; 1 is a shot administered once a week. Participants will begin taking the drugs during a 5-day stay in the clinic. Then they will have 15 outpatient visits while taking the drugs and 7 more after they finish. The last 3-day clinic stay will be 6 months after participants finish taking the drugs. The liver biopsy, imaging scans, and other tests will be repeated.
