•1\. Have a documented total alpha1\-PI serum level \< 11 µM.
•2\. Have a diagnosis of congenital AATD with an allelic combination of ZZ, SZ, Z(null), (null)(null), S(null), or at\-risk” alleles. If the genotype has yet to be documented, genotyping (i.e., allelic discrimination) and phenotyping will be performed at the Screening (Week \-3\) Visit.
•3\. At the Screening (Week \-3\) Visit, have a post\-bronchodilator FEV1 \= 30% and \< 80% of
•predicted and FEV1/forced vital capacity (FVC) \< 70% (Global Initiative for Chronic
•Obstructive Lung Disease \[GOLD] stage II or III).
•4\. Have a carbon monoxide diffusing capacity (DLCO) \= 60% of predicted (corrected for HgB) within the past 2 years OR evidence of pulmonary emphysema on CT scan within the past 2 years per the Investigator’s judgment.
•5\. Have clinical evidence of pulmonary emphysema per the Investigator’s judgment.
•Are the trial subjects under 18? no
•Number of subjects for this age range:
•F.1\.2 Adults (18\-64 years) yes

•1\. Has received alpha1\-PI augmentation therapy for more than 1 month within the six months prior to the Screening (Week \-3\) Visit.
•2\. Has received alpha1\-PI augmentation therapy within one month of the Screening (Week \-3\) Visit.
•3\. Has had a COPD exacerbation within the 5 weeks prior to the Screening (Week \-3\) Visit or during the Screening Phase. Investigator discretion should be used to determine if a subject is appropriate for study participation if the subject has had a COPD exacerbation which occurred more than 5 weeks prior to the Screening (Week \-3\) Visit.
•4\. Unable to physically (e.g., unable to fit inside the CT scanner) or mentally (e.g., claustrophobic) undergo a CT scan.
•5\. History of lung or liver transplant.
•6\. Any lung surgery during the past 2 years (excluding lung biopsy).
•7\. On the waiting list for lung surgery, including lung transplant.
•8\. Smoking during the past 12 months or a positive urine cotinine test at screening that is due to smoking.
•9\. History of anaphylaxis or severe systemic response to any plasma\-derived alpha1\-PI preparation or other blood product(s).
•10\. Use of systemic steroids above a stable dose equivalent to 5 mg/day prednisone (i.e.,
