Outcome Measures
Primary Outcomes (1)
The Primary Outcome Will be to Determine the Effect of Carbamazepine on Hepatic ATZ Load.
The effect of Carbamazepine on hepatic ATZ load will be measured by the number of hepatocytes with PAS+/diastase-resistant globules and/or steady state levels of ATZ by immunoblot analysis.
52 weeks
Secondary Outcomes (1)
For the Secondary Outcomes we Will Determine the Effect of Carbamazepine Treatment on Hepatic Fibrosis.
52 weeks
Study Arms (2)
Drug-Carbamazepine (Tegretol XR)
ACTIVE COMPARATOROne arm receives Drug-Carbamazepine (Tegretol XR).All subjects have severe liver disease due to alpha-1-antitrypsin deficiency.
Drug-Carbamazepine (Tegretol XR) Placebo
PLACEBO COMPARATOROne arm receives Carbamazepine (Tegretol-XR) placebo.All subjects have severe liver disease due to alpha-1-antitrypsin deficiency.
Interventions
To reduce the likelihood of hypersensitivity reactions the subjects will be started on 400 mg/day in 2 doses and the dose will be increased weekly by 200mg/day until reaching a stable therapeutic concentration with a dose not exceeding 1200mg/day(or 1000mg/day in subjects less than 15 years of age). The CBZ tablets will be encapsulated..
Carbamazepine (Tegretol XR)Placebo-the subjects will be started on 400mg/day in 2 doses and the dose will be increased weekly by 200 mg/day until reaching a dose not exceeding 1200 mg/day (or 1000 mg/day in subjects less than 15 years of age). The placebo group will receive encapsulated tables without Carbamazepine.
Eligibility Criteria
You may qualify if:
- Age greater than or equal to 14 years to less than or equal to 80 years of age.
- Alpha-1-Antitrypsin deficiency confirmed by ZZ or SZ phenotype \& serum level
- \< 83mg/dl.
- HVPG greater than or equal to 10 mmHg unless collateral vessels are visualized via transvenous biopsy.
You may not qualify if:
- Child Pugh Score greater than or equal to 12. Serum total bilirubin \> 5 mg/dl. INR \> 2.2.

Limitations and Caveats
The primary \& secondary outcomes could not be assessed because the number of subjects with available pre \& post biopsies was insufficient in subject number and sample quality to conduct the analyses. As described in more detail in Outcome Measures. .

Data Sharing
- IPD Sharing
- Will share
We will share data and liver tissue with other researchers. They may be doing research in areas similar to this research or in other unrelated areas. These researchers may be at Washington University, at other research centers and institutions, or industry sponsors of research. We may also share research data with large data repositories (a repository is a database of information) for broad sharing with the research community. If individual research data is placed in one of these repositories only qualified researchers, who have received prior approval from individuals that monitor the use of the data, will be able to look at the information.
