NCT ID: NCT00161707

Last Updated: 2021-05-05

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 40 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2003-01-07
• Study Completion Date: 2003-10-01

Brief Summary

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.

Conditions

Eligibility Criteria

Inclusion Criteria
