Inquiry Form for the Alpha-1 Biomarker Consortium (A1BC) Study

In May 2020, the National Institutes of Health awarded a grant to identify and characterize biomarkers in Alpha-1 Antitrypsin Deficiency. The grant was awarded to Jeanine D’Armiento, MD, PhD at Columbia University in New York City and Charlie Strange, MD at the Medical University of South Carolina as Co-Principal Investigators. 

What is a Biomarker?

A biomarker is a quantifiable parameter that is measured and evaluated as an indicator of a disease process or a response to therapy; for example, FEV1 is used to predict lung decline. Progression of lung disease in patients with Alpha-1 Antitrypsin Deficiency is variable and while some patients may have stable lung function over many years, some progress and deteriorate rapidly.

About the A1BC Study

The A1BC study will follow a cohort of patients with confirmed PiZZ Alpha-1 Antitrypsin Deficiency to measure a number of different biomarkers in blood and sputum and obtain high resolution CT scans at baseline, 18 months and 3 years later. If the study is able to determine markers that allow the identification of patients at risk for lung function decline, the investigators may be able to study early interventions and find ways to avoid serious complications.

Who is Eligible to Participate in the A1BC?

The A1BC Study is looking for patients who are:

  1. ZZ Alphas
  2. Adults 18 years and older
  3. Enrolled in the Alpha-1 Research Registry
