Safety Study of an Aerosolized, Recombinant Alpha 1-Antitrypsin in Subjects With Alpha 1-Antitrypsin Deficiency

Completed · Phase 1/Phase 2

Conditions studied: Alpha1-antitrypsin Deficiency

In brief

The purpose of this randomized, double-blind, placebo-controlled study is to evaluate the short-term safety of inhaled recombinant alpha 1-antitrypsin (rAAT) in subjects with alpha 1-antitrypsin deficiency. The subjects are randomized to receive placebo or one of 4 doses of rAAT. The 4 doses are tested in a consecutive manner from lowest to highest.

• If female of childbearing potential, negative urine pregnancy test within 3 days prior to randomization and agreement to employ adequate birth control measures
• No clinically significant abnormalities detected on a 12-lead electrocardiogram (ECG) performed no more than 7 days prior to randomization
