The purpose of this clinical study (ChAMP - Comparability pharmacokinetics of Alpha-1 Modified Process) is to compare the pharmacokinetic, safety and tolerability of Alpha-1 Proteinase Inhibitor (Human), modified process (Alpha-1 MP) and Prolastin in adult Alpha1-antitrypsin deficient patients. Patients will be infused intravenously with study drug on a weekly schedule for 24 weeks.

Primary Outcome Measures:
  • Alpha-1 MP vs. Prolastin® of Area Under the Curve (AUC) From Day 0 to Day 7 [ Time Frame: Day 0 to Day 7 ]
    The primary objective of this study was to demonstrate the pharmacokinetic comparability (geometric least square mean ratio of AUC between the Alpha-1 MP vs. Prolastin®, 90% confidence interval falls within 0.80-1.25, FDA Guidance as being "bioequivalent" between two treatments) of Alpha-1 MP to Prolastin® in subjects with alpha-1-anti-trypsin (AAT) deficiency by comparing AUC from Day 0 to Day 7 of plasma Alpha1-PI measured by the functional activity (potency) assay. AUC from Day 0 to Day 7 was calculated at steady state at the end of the first and second 8-week treatment periods during the 16-week double-blind, crossover phase.

Detailed Description:

The objective of this study is to demonstrate the pharmacokinetic comparability of Alpha-1 MP to Prolastin® in subjects with Alpha1-antitrypsin deficiency.

This study is divided into three 8-week treatment sequences including an initial 8-week double-blind treatment period (with one of the 2 study drugs), a second 8-week double-blind treatment period (with the other study drug), and a third 8-week open-label treatment period (with Alpha-1 MP).
