             or who are post-menopausal or surgically sterilized.

          -  Diagnosis of alpha1-antitrypsin deficiency [only individuals with a ZZ or Z null

          -  Forced expiratory volume in one second (FEV1) ≥ 50% of predicted post bronchodilator

          -  No respiratory exacerbations within 6 weeks of baseline. Subjects can be re-screened
             if exacerbations exist at the time of enrollment.

          -  No signs of chronic and/or acute Hepatitis A, Hepatitis B, Hepatitis C, HIV infection
             and Parvovirus B19, by NAT (for Parvovirus B19, nucleic acid testing (NAT) result must
             be < 10^4 IU/mL).

          -  No significant abnormalities in serum hematology, serum chemistry, serum inflammatory
             / immunogenic markers and urinalysis.

          -  No significant abnormalities in ECG.

          -  Not on intravenous augmentation therapy for at least 8 weeks prior to initial dosing
             with study drug/placebo and willing to forego intravenous augmentation therapy for the
             duration of the study.

        Exclusion Criteria:

          -  Clinically significant intercurrent illnesses (except for respiratory or liver disease
             secondary to AAT deficiency), including: cardiac, hepatic, renal, endocrine,
             neurological, hematological, neoplastic, immunological, skeletal or other) that in the
             opinion of the investigator, could interfere with the safety, compliance or other

          -  Allergy to lidocaine or any other medicines used in the bronchoscopy process

          -  Exacerbation of chronic obstructive pulmonary disease (COPD) in the previous 6 weeks.

          -  Participation in another clinical trial involving investigational medication or
             interventional treatment within 30 days prior to baseline visit.

          -  Participation in observational clinical trial which involves any invasive procedure
             scheduled to occur during the AAT inhaled study period. If participating in an
             observational clinical trial that already completed all diagnostic procedures (e.g.
             liver biopsy), any adverse events (AEs) experienced must have returned to baseline
             within 30 days prior to baseline visit.
