Gene Therapy for Alpha 1- Antitrypsin Deficiency
Trial Parameters
Brief Summary
This is a study of gene therapy to treat alpha 1-antitrypsin (AAT) deficiency. This study aims to treat AAT deficiency with a single administration of AAV8hAAT(AVL), a gene therapy that codes for an oxidation resistant form of the AAT protein, which if safe and if efficacious, will protect the lung on a persistent basis. We hope to learn the safety/toxicity and initial evidence of efficacy of intravenous delivery of this gene therapy to alpha 1-antitrypsin deficient individuals.
Eligibility Criteria
Inclusion Criteria: * AAT genotype ZZ, or Z null heterozygotes, and if on augmentation therapy, pre-therapy AAT serum levels \<11 μM * Emphysema as assessed by chest high resolution computational tomography (HRCT) * Lung function parameters consistent with mild to moderate loss of lung function and the presence of emphysema. * Troponin T within normal limits * Normal liver ultrasound and serum alpha fetoprotein * Normal kidney function * No contraindications to receiving corticosteroid immunosuppression Exclusion Criteria: * Individuals receiving systemic corticosteroids or other immunosuppressive medications for pre-existing conditions. * Inability to tolerate immunosuppression with corticosteroids (e.g., uncontrolled diabetes) * Individuals with an immunodeficiency disease, or evidence of active infection of any type, including human immunodeficiency virus * Evidence of major central nervous system, major psychiatric, musculoskeletal or immune disorder * Prior history of myocardial i
