(alglucosidase alfa) for Injection, for Intravenous Use




Life-threatening anaphylactic reactions, severe allergic reactions and immune mediated reactions have been observed in some patients during LUMIZYME infusions. Therefore, appropriate medical support should be readily available when LUMIZYME is administered [see WARNINGS AND PRECAUTIONS].

Because of the potential risk of rapid disease progression in Pompe disease patients less than 8 years of age, LUMIZYME is available only through a restricted distribution program called the LUMIZYME ACE Program®. Only prescribers and healthcare facilities enrolled in the program may prescribe, dispense or administer LUMIZYME. LUMIZYME may be administered only to patients who are enrolled in and meet all the conditions of the LUMIZYME ACE Program. To enroll in the LUMIZYME ACE Program call 1-800-745-4447 [see WARNINGS AND PRECAUTIONS].


LUMIZYME (alglucosidase alfa) consists of the human enzyme acid α-glucosidase (GAA), encoded by the most predominant of nine observed haplotypes of this gene. LUMIZYME is produced by recombinant DNA technology in a Chinese hamster ovary cell line. The LUMIZYME manufacturing process differs from that for MYOZYME®, resulting in differences in some product attributes. Alglucosidase alfa degrades glycogen by catalyzing the hydrolysis of a-1,4- and a-1,6- glycosidic linkages of lysosomal glycogen.

Alglucosidase alfa is a glycoprotein with a calculated mass of 99,377 daltons for the polypeptide chain, and a total mass of approximately 109,000 daltons, including carbohydrates. Alglucosidase alfa has a specific activity of 3 to 5 Units/mg (one unit is defined as that amount of activity that results in the hydrolysis of 1 micromole of synthetic substrate per minute under specified assay conditions). LUMIZYME is intended for intravenous infusion. It is supplied as a sterile, nonpyrogenic, white to off-white, lyophilized cake or powder for reconstitution with 10.3 mL Sterile Water for Injection, USP. Each 50 mg vial contains 52.5 mg alglucosidase alfa, 210 mg mannitol, 0.5 mg polysorbate 80, 9.9 mg sodium phosphate dibasic heptahydrate, 31.2 mg sodium phosphate monobasic monohydrate. Following reconstitution as directed, each vial contains 10.5 Ml reconstituted solution and a total extractable volume of 10 mL at 5 mg/mL alglucosidase alfa. LUMIZYME does not contain preservatives; each vial is for single use only.

What are the possible side effects of alglucosidase alfa (Lumizyme, Myozyme)?

Some people receiving an injection of alglucosidase alfa have had a reaction to the infusion. This type of reaction can occur when the medicine is injected into the vein, or as long as 3 hours after the injection. Tell your caregivers or get emergency medical help right away if you have any of these signs of a severe allergic reaction:

  • feeling like you might pass out, even while lying down;
  • feeling restless, nervous, dizzy, or nauseated;
  • pale skin, redness under your skin, sweating, feeling hot or cold;
  • fast or slow heart...
