An Open-Label, Multicenter, Randomized, Non-Inferiority Pharmacokinetic and Safety/Tolerability Study of Two Different Weekly Doses of Alpha1-Proteinase Inhibitor Subcutaneous (Human) 15% in Patients With Alpha1-Antitrypsin Deficiency Compared to Corresponding Standard 60 mg/kg/Week and 120 mg/kg/Week Doses of Intravenous Alpha1-Proteinase Inhibitor (5%)

Summary

This study is designed to compare two different weekly doses of a medicine called Alpha1-Proteinase Inhibitor given by injection under the skin with the standard doses of the same medicine given through a vein. Adults with Alpha-1 Antitrypsin Deficiency will take part. Participants will be randomly assigned to one of the treatment groups, and both the study doctors and participants will know which treatment is being given. The main goals of the study are to understand how the body processes the medicine (pharmacokinetics) and to assess how safe and well tolerated the different weekly doses are.
