Summary:

      The purpose of this study is to evaluate the effects of weekly augmentation therapy with
      ARALAST Fraction IV-1 (Fr IV-1) on epithelial lining fluid (ELF) alpha 1-proteinase inhibitor
      levels and other ELF analytes and to assess the safety of the treatment. Eligible subjects
      with a diagnosis of severe congenital alpha 1-antitrypsin deficiency will receive 8
      consecutive weekly treatments with 60 mg/kg/week of functional ARALAST Fr IV-1 administered
      intravenously. The efficacy and safety assessments will include two bronchoscopies with
      bronchoalveolar lavage on study initiation and on study termination and multiple imaging and
      laboratory safety assessments. Each subject will participate for a minimum of 12 weeks.

             otherwise approved by the Sponsor) after a minimum of 28-day washout of any prior
             replacement therapy (if applicable).

          -  Pulmonary functions at screening meeting the following criteria:

               1. Forced expiratory volume at 1 second (FEV1) >= 50% of predicted value; or

               2. FEV1 > 35% of predicted value and diffusing capacity for carbon monoxide > 45% of
                  predicated value, with no supplemental oxygen therapy and < 3 pulmonary
                  exacerbations or bronchitis requiring antibiotics/corticosteroids within the past
                  12 months).

          -  For any female of childbearing potential, a negative urine test for pregnancy within 7
             days prior to the first bronchoalveolar lavage (BAL) visit and agreement to employ
             adequate birth control measures for the duration of the study.

          -  No clinically significant abnormalities detected on a 12-lead electrocardiogram (ECG)
             performed at the screening visit (ECG previously obtained within the past 12 months
             may be used, if available).

               8. Platelet count >= 105/mm3

          -  If the subject is treated with respiratory medications, such as inhaled
             bronchodilators or inhaled corticosteroids, or other chronic medications for the
             treatment of the subjects´s other medical condition(s), the subject's medication doses
             were unchanged for at least 14 days prior to the baseline BAL visit.

        Exclusion Criteria:

          -  Clinically significant pulmonary impairment, other than chronic pulmonary disease
             (COPD).

          -  The subject has received any alpha 1 proteinase inhibitor (α1-PI) augmentation therapy

             including intravenous and inhaled) within 28 days prior to screening.

          -  The subject has received an investigational drug or device within 1 month prior to
             screening, or the subject is currently receiving an investigational drug or device. If
             the subject receives another investigational drug or device after enrollment, the
             subjects is to be withdrawn from the trial.

             pulmonary exacerbation within 14 days prior to screening.

             than 15 mg/dL) and/or antibody against IgA.

          -  The subject is pregnant or lactating, or intends to become pregnant during the course
             of the study.
