Lung Volume Reduction Coils for Emphysema in Alpha-1 Antitrypsin Deficiency

Official Title

Evaluation of the PneumRx, Inc. Lung Volume Reduction Coil for the Treatment of Emphysema in Alpha-1 Antitrypsin Deficient Patients

Brief Summary

      The objective of this study is to evaluate the safety and effectiveness of the RePneu Lung
      Volume Reduction Coil (LVRC) in patients with Alpha-1-Antitrypsin deficiency (AATD) caused
      emphysema. The hypothesis is that emphysema in AATD patients shows similar tissue destruction
      profile was well as symptoms and thus will respond favorably to LVRC treatment, demonstrating
      improvement in lung function, exercise capacity, and quality of life relative to their
      baseline status.

Study Type


Primary Outcome

symptomatic improvement in St. George's Respiratory Questionnaire (SGRQ) from Baseline (Pre-Treatment Visit) compared to the 6 months Follow-up Visit

Secondary Outcome

 Percent change in FEV1 from Baseline (Pre-Treatment Visit)
