This medicinal product is indicated for the substitution treatment of severe forms of primary alpha-1 antitrypsin deficiency in subjects with phenotype PiZZ or PiSZ with pulmonary emphysema.

Dosage ALFALASTIN 33.33 mg / mL Powder and solvent for solution for injection Box of 1 vial of powder (+ disptransfer) + fl of solvent of 120 ml

Treatment should be started as soon as possible when the first signs of emphysema appear.

This treatment is to be continued:

· Continuously, especially in cases of highly progressive emphysema,

· Either by discontinuous cures during bronchopulmonary infectious outbreaks.

Continuous or recurrent exposure to aerocontaminants that may increase intrapulmonary protease load is the only known factor in the development of emphysema. Stopping smoking is therefore imperative and protection of the subject against potential professional air contaminants is strongly recommended.

Dosage

A dose of 60 mg / kg of ALFALASTIN injected once a week, intravenously, provides a plasma level of alpha-1 antitrypsin comparable to that of non-deficient subjects.

Alpha-1 antitrypsin assays should be performed on the patient once a month for the first six months of treatment and then every three to four months thereafter. The doses to be injected will eventually be corrected so as to maintain a minimum plasma level of 11 μM (0.50 g / l) at 15 μM (0.70 g / l).

Method and route of administration

ALFALASTIN is a powder to be reconstituted extemporaneously with water for injections, according to the procedures described in the section Instructions for use, handling and disposal .

ALFALASTIN should be injected intravenously, all at once, immediately after reconstitution, without exceeding a flow rate of 4 ml / min.
