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

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02273349
Recruitment Status : Withdrawn

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.

Arm Intervention/treatment
Experimental: Treatment
Patients with Alpha-1-Antitrypsin deficiency treated with endoscopic lung volume reduction using Lung Volume Reduction Coils (PneumRx Inc.)
Device: Lung Volume Reduction Coil (PneumrX Inc.)
Endoscopic Lung Volume Reduction

Primary Outcome Measures :
  1. symptomatic improvement in St. George's Respiratory Questionnaire (SGRQ) from Baseline (Pre-Treatment Visit) compared to the 6 months Follow-up Visit [ Time Frame: 6 months ]
    Quality of Life

Secondary Outcome Measures :
  1. Percent change in FEV1 from Baseline (Pre-Treatment Visit) [ Time Frame: 6 and 12 months ]
    Lung function

  2. Decrease in the Residual Volume and the RV/TLC ratio [ Time Frame: 6 and 12 months ]
    Lung function

  3. Improvement in the 6 minute walk distance [ Time Frame: 6 and 12 months ]

  4. Changes in mMRC Dyspnoe Scale [ Time Frame: 6 and 12 months ]

Other Outcome Measures:
  1. Number and type of device-related and procedure-related serious adverse events (SAE) attributed to the use of RePneu LVRC [ Time Frame: up to 6 months ]
    SAE device and procedure related
