About this study

This is a long-term follow-up banking protocol that collects medical information and tissue (blood, liver and lung) samples for future research; use of data and samples for research purposes is overseen by the Tissue Bank Advisory Committee; the purpose of the Bank is to further research on alpha-1 antitrypsin deficiency.

Read the detailed description

Subject participation includes completion of informed consent, medical questionnaire, and email authorization. Subjects may provide a blood sample for alpha-1 antitrypsin genotype, phenotype and level. Lung and liver tissue may also be provided if available. Subjects may be contacted no more often than annually for updated information.

This project has a certificate of confidentiality from NIH.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Data and tissue samples

    At the end of 15 years the tissue and data sample usage will be analyzed to determine continuation of the project. Each year the investigator provides a summary to the Alpha-1 Foundation.

    Measured: The total number of tissue samples received and used for research are tracked annually.

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?

Data and tissue samples (time frame: The total number of tissue samples received and used for research are tracked annually.). 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 NCT00884455, which also lists 2 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?
