About this trial

This is a Phase 1, open-label, single ascending dose (SAD) and multiple dose (MD) study of AIR-001 in participants with alpha-1 antitrypsin deficiency (AATD) due to PiZZ genotype.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Male or female participants >18 years and <75 years of age at the time of signing informed consent

Total serum AAT levels < 11µM (57 mg/dL)

Pi*ZZ genotype confirmed by DNA sequencing within the SERPINA1 gene with no known co-occurring SERPINA1 null variants

Spirometry: Forced expiratory volume in 1 second (FEV1) ≥ 40% of predicted

Disqualifiers

Female participants who are nursing or lactating

Participant has received AAT augmentation therapy within 30 days prior to Screening Visit or plans to receive AAT augmentation therapy at any time during study participation.

Known or suspected allergy or intolerance to AIR-001 or its components

Acute respiratory tract infection or clinically-diagnosed chronic obstructive pulmonary disease (COPD) exacerbation that required antibiotic treatment and/or systemic corticosteroids within the 8 weeks prior to dosing.
