ClinicalTrials.gov Identifier:	NCT00295061

Purpose

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.

Arms	Assigned Interventions
1 Alpha-1 MP: Experimental Sequential, blinded treatment periods of Alpha-1 MP (experimental), then crossed-over to Prolastin (active comparitor), followed by open-label Alpha-1 MP	Drug: alpha-1 proteinase inhibitor (human) Alpha-1 MP
2 Prolastin: Active Comparator Sequential, blinded treatment periods of Prolastin (active comparitor), then crossed-over to Alpha-1 MP (experimental), followed by open-label Alpha-1 MP	Drug: alpha-1 proteinase inhibitor (human) Prolastin

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).
