Hepatitis DPhase 2NCT01495585
Lonafarnib for Chronic Hepatitis D
A Phase 2 study testing Lonafarnib in people with Hepatitis D, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at 1 site in United States.
Trial summary
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. Read more about this study

- All sexes
- No healthy volunteers
- Adult, Older adult
Who may be able to join
- Age 18 years or above, male or female.
- Serum alanine or aspartate aminotransferase activities above the upper limit of normal (ALT > 41 or AST > 31 U/L) on an average of three determinations taken during the previous 6 months. The mean of the three determinations will be defined as baseline levels.
- Presence of anti-HDV in serum.
- Evidence of chronic hepatitis on liver biopsy done within the previous 12 months with a necroinflammatory score in histology activity index of at least 5 (out of a maximum of 18) and at least 1 for hepatic fibrosis (out of a maximum of 6).

- Written informed consent.
Who cannot join
- Decompensated liver disease, defined by bilirubin > 4mg/dL, albumin < 3.0 gm/dL, prothrombin time > 2 sec prolonged, or history of bleeding esophageal varices, ascites or hepatic encephalopathy. Laboratory abnormalities that are not thought to be due to liver disease may not necessarily require exclusion. Patients with ALT levels greater than 1000 U/L (> 25 times ULN) will not be enrolled but may be followed until three determinations are below this level.
- Pregnancy or inability to practice adequate contraception, in women of childbearing potential or in spouses of such women. Adequate contraception is defined as vasectomy in men, tubal ligation in women, or use of two barrier methods such as condoms and spermicide combination, birth control pills, an intrauterine device, Depo-Provera, or Norplant.
- Significant systemic or major illnesses other than liver disease, including, but not limited to, congestive heart failure, renal failure (eGFR < 50 ml/min), organ transplantation, serious psychiatric disease or depression (only if felt to be at high risk by the NIH psychiatric consultation service), and active coronary artery disease.
- Systemic immunosuppressive therapy within the previous 2 months.
- Evidence of another form of liver disease in addition to viral hepatitis (for example autoimmune liver disease, primary biliary cirrhosis, primary sclerosing cholangitis, Wilson disease, alcoholic liver disease, nonalcoholic steatohepatitis (but not steatosis), hemochromatosis, or alpha-1-antitrypsin deficiency).

About this study
Official title: Treatment of Chronic Delta Hepatitis With Lonafarnib
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....
Read the detailed description
Chronic delta hepatitis is a serious form of chronic liver disease caused by infection with the hepatitis D virus (HDV), a small RNA virus that requires farnesylation of its major structural protein (HDV antigen) for replication. We propose to treat between 12 and 14 patients with chronic delta hepatitis using the farnesyltransferase inhibitor (FTI) lonafarnib for a duration of twenty-eight days. Farnesyltransferase inhibitors have not been used in the therapy of delta hepatitis. Patients with HBsAg and HDV RNA in serum, elevated aminotransferases, or moderate-to-severe chronic hepatitis and HDV antigen on liver biopsy will be enrolled. Before receiving therapy, patients will be monitored for at least three months with regular testing for alanine aminotransferase (ALT) levels and will undergo Clinical Center admission for medical evaluation and percutaneous liver biopsy. Two dosing groups of lonafarnib will be assessed, with a placebo cohort in each group. At each clinic visit, patients will be questioned about side effects and symptoms, undergo focused physical examination, and have blood drawn for complete blood counts, HDV RNA, and routine liver tests (including ALT, AST, alkaline phosphatase, direct and total bilirubin, and albumin). At two-week intervals, for a period of 28 days, patients will also be tested for HBsAg, anti-HBs, HBV DNA, and prothrombin time. At the end of 28 days of treatment, patients will undergo repeat physical examination, assessment of symptoms (using a symptom scale questionnaire), complete blood counts, routine liver tests, and hepatitis B and D viral markers. The primary therapeutic endpoint will be an improvement in quantitative serum HDV RNA levels after 28 days of lonafarnib therapy. The primary safety endpoint will be the ability to tolerate the drug at the prescribed dose for the 4 week duration. Several secondary endpoints will be measured, including side effects, ALT levels, and symptoms. Therapy will be stopped for intolerance to lonafarnib (which will be carefully defined). This study is designed as a phase 2a study assessing the safety, tolerance and antiviral activity of two dose levels of lonafarnib, a farnesyltransferase inhibitor.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Lonafarnib in people with Hepatitis D, run by National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 31 Aug 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 31 Aug 2016). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in Quantitative Serum HDV RNA Levels After 28 Days of Lonafarnib Therapy. (time frame: 28 days). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01495585, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Aug 2016.
