Alpha-1 antitrypsin (AAT) deficiency enzyme replacement therapy: alpha-1 proteinase inhibitor (Aralast/NP®, Glassia®, Prolastin/C® and Zemaira®) - Minnesota Health Care Programs

These services may or may not be covered by your HealthPartners plan. Please see your plan documents for your specific coverage information. If there is a difference between this general information and your plan documents, your plan documents will be used to determine your coverage.

Administrative Process

Drug therapies to replace alpha-1 proteinase inhibitor in individuals with alpha-1 antitrypsin deficiency require prior authorization from Pharmacy Administration.

Coverage

Coverage for drug therapy in alpha-1 antitrypsin deficiency is generally provided when medically necessary.

Alpha-1 antitrypsin (AAT) inhibitor therapy is medically necessary for members with emphysema due to AAT deficiency when all the following criteria are met:

  1. Low serum concentration of AAT < 11 micromoles/L (or less than 80mg/dL or less than 0.8 g/L), which is considered the threshold thought to protect against emphysema; and
  2. Progressive panacinar emphysema is present with a documented rate of decline in forced expiratory volume in 1 second (FEV1); and
  3. Ex-smoker or non-smoker.

Definitions

Alpha-1 antitrypsin deficiency: Alpha-1 antitrypsin is an antiprotease found in human plasma that inhibits the neutrophil elastase enzyme from degrading elastin tissues in the lung. Deficiency is an inherited disorder associated with the early onset of pulmonary emphysema in adults. Although replacement therapies have not been shown to prevent or reverse emphysema in AAT deficiency, population studies suggest a minimum plasma threshold of 11 micromoles/L, below which there is insufficient AAT to protect the lung leading to emphysema.

Alpha-1 proteinase inhibitor therapy is indicated for chronic augmentation and maintenance therapy in adults with emphysema due to congenital deficiency of alpha1-proteinase inhibitor. The effect of augmentation therapy on pulmonary exacerbations and on the progression of emphysema in alpha1-deficiency has not been demonstrated in randomized, controlled clinical trials. Clinical data demonstrating the long-term effects of chronic augmentation and maintenance therapy of individuals is not available. It is not indicated as therapy for lung disease in patients in whom severe alpha1-proteinase deficiency has not been established.

Currently available alpha-1 proteinase inhibitor products include Aralast NP®, Glassia®, Prolastin®-C and Zemaira®.
