Alpha-1 Proteinase Inhibitor (Alpha-1PI) Deficiency or Alpha-1 Antitrypsin (AAT) Deficiency is a rare, chronic, autosomal, co-dominant hereditary disorder characterized by reduced or non-existent levels of endogenous Alpha-1PI in the blood and lungs. Alpha-1-antitrypsin (AAT), a naturally occurring inhibitor of serine proteases such as neutrophil elastase, is normally produced in the liver. With insufficient Alpha-1PI, proteolytic enzymes, such as trypsin and elastin become imbalanced, resulting in a gradual destruction of pulmonary connective tissue and loss of alveolar units, presenting as slowly progressive, moderate to severe panacinar emphysema that presents most often in the third or fourth decade of life .
AAT blocks the destructive action of trypsin and elastin as well as several other proteases. Replacement therapy for AAT deficiency with human plasma derived Alpha-1PI has been shown to increase serum and lung levels of AAT with significantly lower CT-measured mean annual rate of lung density loss at total lung capacity.
· Alpha-1 proteinase inhibitor therapy is considered medically necessary for the treatment of emphysema due to congenital alpha-1 antitrypsin (AAT) deficiency if the medical appropriateness criteria are met. (See Medical Appropriateness below.)
· Alpha-1 proteinase inhibitor therapy for the treatment of other conditions/diseases, including, but not limited to, the following is considered investigational:
Lung disease without congenital alpha-1-antitrypsin (A1A) deficiency
INITIAL APPROVAL CRITERIA
· Patient is at least 18 years of age; AND
· Patient is not a tobacco smoker; AND
· Patient is receiving optimal medical therapy (e.g., comprehensive case management, pulmonary rehabilitation, vaccinations, smoking cessation, self-management skills, etc.); AND
· Patient does not have immunoglobulin-A (IgA) deficiency with antibodies against IgA; AND
Emphysema due to alpha-1-antitrypsin (AAT) deficiency
· Patient has an FEV1 in the range of 30-65% of predicted; AND
· Patient has alpha-1-antitrypsin (AAT) deficiency with PiZZ, PiZ (null), or Pi (null, null) phenotypes; AND
· Patient has AAT- deficiency and clinical evidence of panacinar/panlobular emphysema; AND
· Patient has low serum concentration of AAT ≤ 57 mg/dL or ≤ 11 μM/L as measured by nephelometry
· Patient continues to meet universal and other indication-specific relevant criteria such as concomitant therapy requirements (not including prerequisite therapy), performance status, etc. identified in the Initial Approval Criteria; AND
· Disease response with treatment as defined by elevation of AAT levels above baseline, substantial reduction in rate of deterioration of lung function as measured by percent predicted FEV1, or improvement in CT scan lung density; AND
· Absence of unacceptable toxicity from the drug. Examples of unacceptable toxicity include severe hypersensitivity reactions, etc.
