Study of the Effect of Aerosolized, Recombinant Alpha 1-Antitrypsin on Epithelial Lining Fluid Analytes in Subjects With Alpha 1-Antitrypsin Deficiency
Summary
The study was a Phase 1B/2A, uncontrolled, open-label, single-center study in individuals with congenital AAT (alpha 1-antitrypsin) deficiency. A baseline bronchoscopy with bronchoalveolar lavage (BAL) was performed 3 to a maximum of 4 weeks prior to the first administration of study drug. Fifteen eligible subjects were randomized to receive 1 of 3 dosing regimens of rAAT (100 mg daily, 100 mg twice daily, or 200 mg daily) administered via nebulization for 7 consecutive days. A post-treatment nadir BAL was obtained on study Day 8 (12 hours after last dose for subjects who receive drug therapy twice daily and 24 hours after the last dose for subjects who receive study product daily). BALs were conducted in the same lung lobe/segment. Follow-up visits took place on Day 15 and Day 36.
