Lumizyme® (alglucosidase alfa) is supplied as a sterile, nonpyrogenic, white to off-white lyophilized cake or powder that must be reconstituted for intravenous administration. Certain measures, outlined below, should be followed to ensure proper product storage and preparation for infusion.
Lumizyme is available only in 50 mg units, supplied in single-dose vials. Lumizyme does not contain any preservatives and should be stored and handled according to these guidelines:
Lumizyme should be reconstituted, diluted, and administered by a health care professional using aseptic technique. Do not use filter needles during preparation. Reconstitution devices may be used to prepare successive vials of Lumizyme without the need to enter and withdraw from numerous vials of sterile water. Such devices are available from Sanofi Genzyme by contacting Medical Information at 800-745-4447, option 2.
Remove Lumizyme vials from refrigeration and allow them to reach room temperature (about 30 minutes) before starting reconstitution. Organize a clean work area and prepare the following supplies:
1. Lumizyme 50 mg vials
2. Sterile Water for Injection, USP
3. 0.9% Sodium Chloride for Injection, USP
4. Syringes for reconstitution and dilution
5. Needles (do not use filter needles during preparation)
6. Intravenous administration set
7. In-line low protein-binding 0.2 μm filter
You may need additional supplies, depending on the IV infusion protocol of your facility or practice.
The recommended dosage of Lumizyme is 20 mg per kg of body weight (administered every two weeks). For more details on calculating vials needed per dose and recommended total infusion volume based on patient weight, see the Dosing & Administration page.

LUMIZYME® (alglucosidase alfa) is a hydrolytic lysosomal glycogen-specific enzyme indicated for patients with Pompe disease (GAA deficiency).
WARNING: HYPERSENSITIVITY REACTIONS INCLUDING ANAPHYLAXIS, IMMUNE-MEDIATED REACTIONS, AND RISK OF ACUTE CARDIORESPIRATORY FAILURE
Hypersensitivity Reactions Including Anaphylaxis
Patients treated with LUMIZYME have experienced life-threatening hypersensitivity reactions, including anaphylaxis. Appropriate medical monitoring and support measures, including cardiopulmonary resuscitation equipment, should be readily available during LUMIZYME administration. If a severe hypersensitivity reaction (e.g. anaphylaxis) occurs, discontinue LUMIZYME immediately and initiate appropriate medical treatment.
Consider risks and benefits of re-administering LUMIZYME following severe hypersensitivity reactions. If a mild or moderate hypersensitivity reaction occurs, the infusion rate may be slowed or temporarily stopped. Prior to LUMIZYME administration, consider pretreating with antihistamines, antipyretics, and/or corticosteroids.
Immune-Mediated Reactions
Immune-mediated reactions presenting as proteinuria, nephrotic syndrome, and necrotizing skin lesions have occurred in some patients following LUMIZYME treatment. Monitor patients for the development of systemic immune-mediated reactions involving skin and other organs while receiving LUMIZYME.
Risk of Acute Cardiorespiratory Failure
Infantile-onset Pompe disease patients with compromised cardiac or respiratory function may be at risk of serious acute exacerbation of their cardiac or respiratory compromise due to fluid overload and require additional monitoring.
Infusion Associated Reactions (IARs): Infusion Associated Reactions (IARs) have been observed in patients treated with Lumizyme. Discontinue immediately or adjust the infusion rate and provide medical treatment based on the severity of the reaction. Closely monitor patients who have experienced IARs when re-administering LUMIZYME.
Risk of Cardiac Arrhythmia and Sudden Cardiac Death during General Anesthesia for Central Venous Catheter Placement: Caution should be used when administering general anesthesia for the placement of a central venous catheter intended for LUMIZYME infusion.
Risk of Antibody Development: Patients with Infantile-onset Pompe disease should have a cross-reactive immunologic material (CRIM) assessment early in their disease course and be managed by a specialist knowledgeable in immune tolerance induction in Pompe disease to optimize treatment. Evidence suggests that patients who develop high and sustained IgG antibody titers may experience reduced clinical efficacy.
Monitoring: Laboratory Tests: Patients should be monitored for IgG antibody formation every 3 months for 2 years and then annually thereafter. Patients who experience hypersensitivity reactions, including anaphylaxis, may also be tested for IgE antibodies to LUMIZYME and other mediators of anaphylaxis.
The most frequently reported adverse reactions (≥ 5%) in clinical trials were hypersensitivity reactions and included: anaphylaxis, rash, pyrexia, flushing/feeling hot, urticaria, headache, hyperhidrosis, nausea, cough, decreased oxygen saturation, tachycardia, tachypnea, chest discomfort, dizziness, muscle twitching, agitation, cyanosis, erythema, hypertension/increased blood pressure, pallor, rigors, tremor, vomiting, fatigue, and myalgia.
