Brief Summary:
Alpha-1 Anti-trypsin Deficiency (AATD) is a genetic disease with lung and liver disease presentations. The purpose of this study is to examine the density of the lung as measured by chest computed tomography (CT) and determine if existing emphysema predicts changes in the rate of subsequent emphysema or changes in CT, serum or plasma biomarkers of interest. The overarching goal is to develop biomarkers that can be used in interventional trials since lung function changes do not typically inform disease progression in AATD.

Condition or disease
Alpha 1-Antitrypsin Deficiency Genetic Disease

Detailed Description:

Progression of lung disease in patients with Alpha-1 Anti-trypsin deficiency is variable and while some patients may have stable lung function over many years, some progress and deteriorate rapidly. Currently there are no predictors that would help identify patient at risk of rapid deterioration. The aim of this study is to identify markers and features in CT imaging that may allow identification of these patients early before deterioration. To achieve this, the study will follow a cohort of patients with confirmed Alpha-1 Anti-trypsin deficiency and lung disease and measure a number of biomarkers in blood and sputum and obtain high resolution CT scans at baseline and again three years later. If the study is able to determine markers that allow the identification of patients at risk early, the investigator may be able to study early interventions in later studies and possibly find ways to avoid serious complications. Patients will be followed longitudinally to assess deterioration of lung function.

Study procedures include: Review of medical history and medication history, blood draw, complete Pulmonary Function Test (PFT), induced sputum (at some sites), completion of questionnaires and CT Chest scan. All of the mentioned procedures above will be performed on enrollment and repeated at 18 months and 36 months, with the exception of monthly Alpha- net exacerbation questionnaires.

Time Perspective: Prospective
Target Follow-Up Duration: 18 Months
Official Title: Alpha-1 Antitrypsin Disease Cohort: Longitudinal Biomarker Study of Disease - Alpha-1 Biomarker Research Consortium (A1BC)
Actual Study Start Date : March 23, 2022
Estimated Primary Completion Date : February 2026
Estimated Study Completion Date : February 2026

Moderate to Advanced Emphysema
Patients with moderate or advanced Emphysema as measured by baseline inspiratory PERC-15 below the study median
Minimal Emphysema
Patients with minimal emphysema as measured by baseline inspiratory PERC-15 above the study median

Primary Outcome Measures :
  1. Change in lung density over three years [ Time Frame: 3 years ]
    Change in lung density over three years determined by using the 15th percentile point of Hounsfield units in inspiratory high resolution CT scans (PERC-15)

Biospecimen Retention:   Samples With DNA
Blood samples will be collected for analysis in the ongoing clinical trial as well as for banking to for a bio-repository for future AATD studies. Participants will have the option to agree/not agree to partake in the optional bio-repository.
