Brief Summary:
This is a multi-center, randomized, placebo-controlled, double blind clinical study to assess the efficacy and safety of two separate dose regimens of Alpha-1 MP versus placebo for 156 weeks (i.e., 3 years) using computed tomography (CT) of the lungs as the main measure of efficacy. The two Alpha-1 MP doses to be tested are 60 mg/kg and 120 mg/kg administered weekly by IV infusion for 156 weeks. The study consists of an optional pre-screening phase, Screening Phase, a 156-week Treatment Phase, and an End of Study Visit at Week 160.

Primary Outcome Measures :
  1. Change from Baseline in Whole lung PD15 (15th percentile point) [ Time Frame: Week -3 (baseline measure), Week 52, Week 104, Week 130, Week 156 ]
    Whole lung PD15 measured by CT scan


Secondary Outcome Measures :
  1. Adverse Events (AEs) [ Time Frame: Week -3 through Week 160 ]
    Monitoring of AEs

  2. Serious Adverse Events (SAEs) [ Time Frame: Week -3 through Week 160 ]
    Monitoring of SAEs

  3. Discontinuations from the study due to AEs [ Time Frame: Week -3 through Week 160 ]
    Monitoring of discontinuations due to AEs

  4. Severe COPD Exacerbations [ Time Frame: Week -3 through Week 160 ]
    Severe COPD exacerbations as defined by American Thoracic Society/European Respiratory Society (ATS/ERS) criteria (i.e., COPD exacerbations requiring hospitalization)

  5. Change from Baseline in PD15 of the basal lung region [ Time Frame: Week -3 (baseline measure), Week 52, Week 104, Week 130, Week 156 ]
    PD15 of the basal lung region measure by CT scan

  6. Change from baseline in carbon monoxide diffusing capacity (DLco) [ Time Frame: Weeks 26, 52, 78, 104, 130 and 156 ]
    DLco performed according to American Thoracic Society/European Respiratory Society (ATS/ERS) guidelines

  7. Changes from baseline in forced expiratory volume in 1 second (FEV1) [ Time Frame: Weeks 26, 52, 78, 104, 130 and 156 ]
    FEV1 performed according to ATS/ERS guidelines

  8. Change from baseline in Saint George's Respiratory Questionnaire: Minimum value = 0, maximum value = 100, higher scores indicate worse condition [ Time Frame: Weeks 26, 52, 78, 104, 130 and 156 ]
    Health-related quality of life assessment tool

  9. Change from baseline in the EuroQoL (Quality of Life)- 5 Dimension- 5 Level (EQ-5D-5L): Minimum value (for each one of the 5 levels) = 1, maximum value (for each one of the 5 levels) = 5, higher scores indicate worse condition [ Time Frame: Weeks 26, 52, 78, 104, 130 and 156 ]

Criteria

Inclusion Criteria:

  • Have a documented total alpha1-PI serum level < 11 µM.
  • Have a diagnosis of congenital AATD with an allelic combination of ZZ, SZ, Z(null), (null)(null), S(null), or "at-risk" alleles.
  • At the Screening (Week -3) Visit, have a post-bronchodilator forced expiratory volume in 1 second (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).
  • 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.
  • Have clinical evidence of pulmonary emphysema per the Investigator's judgment.

Exclusion Criteria:

  • Has received alpha1-PI augmentation therapy for more than 1 month within the six months prior to the Screening Visit.
  • Has received alpha1-PI augmentation therapy within one month of the Screening Visit.
  • Has had a chronic obstructive pulmonary disease (COPD) exacerbation within the 5 weeks prior to the Screening Visit or during the Screening Phase.
  • Unable to physically (e.g., unable to fit inside the CT scanner) or mentally (e.g., claustrophobic) undergo a CT scan.
  • History of lung or liver transplant.
  • Any lung surgery during the past 2 years (excluding lung biopsy).
  • On the waiting list for lung surgery, including lung transplant.
  • Smoking during the past 12 months or a positive urine cotinine test at screening that is due to smoking. Maybe on Nicotine replacement, including vapor cigarettes.
  • History of anaphylaxis or severe systemic response to any plasma-derived alpha1-PI preparation or other blood product(s).
  • Use of systemic steroids above a stable dose equivalent to 5 mg/day prednisone (i.e., 10 mg every 2 days) within the 5 weeks prior to the Screening Visit (inhaled steroids are not considered systemic steroids) or during the Screening Phase.
  • Use of systemic or aerosolized antibiotics for a COPD exacerbation within the 5 weeks prior to the Screening Visit or during the Screening Phase.
  • Known selective or severe Immunoglobulin A (IgA) deficiency.
