Pompe disease is a chronic disorder, in which the body does not produce enough of the acid α-glucosidase (GAA) enzyme on its own. Lumizyme® (alglucosidase alfa) is a medication administered by intravenous infusion to provide a replacement for the missing enzyme directly into the bloodstream. Lumizyme does not correct the underlying genetic cause of Pompe disease and should be administered as prescribed by your doctor.
It is recommended that Lumizyme infusions are administered by a healthcare professional every 2 weeks, and each infusion lasts about 4 hours. You’ll be monitored during the infusion for potential life-threatening reactions. During the infusion, you can do other things such as read, watch television, or visit with family and friends. It’s a good idea to talk to your doctor before you start treatment so you know what to expect and what kind of things you should alert your healthcare team about. If you experience a severe allergic reaction during an infusion, the infusion should be discontinued and you will receive appropriate medical care.
LUMIZYME® (alglucosidase alfa) is an enzyme replacement therapy for patients with Pompe disease (acid α-glucosidase (GAA) deficiency).
WARNING: Risk of anaphylaxis, hypersensitivity and immune-mediated reactions, and risk of cardiorespiratory failure
Anaphylaxis and Hypersensitivity Reactions: Life-threatening anaphylaxis and hypersensitivity reactions have been observed in some patients during and after treatment with alglucosidase alfa. If such a reaction is severe enough, your doctor may decide to immediately discontinue the infusion and provide you with immediate medical care. Appropriate medical support and monitoring measures should be available during infusion.
Immune-Mediated Reactions: You or your child may be monitored for the development of systemic immune-mediated reactions while receiving Lumizyme. If these reactions occur, your doctor may discontinue the infusion and initiate appropriate medical treatment.
Risk of Acute Cardiorespiratory Failure: Infant Pompe patients with heart or breathing problems who are experiencing an acute respiratory condition may be at risk for increasing the seriousness of these problems as a result of Lumizyme administration due to the infusion fluid, and your child’s doctor may require additional monitoring for these infants.
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. Ventricular arrhythmias and slow heart rate resulting in cardiac arrest or death have been observed in infant Pompe patients with cardiac hypertrophy during general anesthesia for central venous catheter placement. Appropriate medical support and monitoring measures should be available during infusion.
Risk of Antibody Development: Since Lumizyme is a protein, it is possible that patients receiving it develop antibodies. Some patients who develop high IgG antibody levels that last for a while may have reduced response to Lumizyme. Patients should be monitored for IgG antibody formation every 3 months for 2 years and then annually thereafter.
The most frequently reported adverse reactions during Lumizyme studies in patients were allergy reactions and included: anaphylaxis, rash, fever, flushing/feeling hot, hives, headache, excessive sweating, nausea, cough, less oxygen in the blood, fast heart rate, rapid breathing, chest discomfort, dizziness, muscle twitching, agitation, bluish or purple skin, redness of skin, high blood pressure/increased blood pressure, facial paleness, chills, tremor, vomiting, fatigue, and muscle pain.
If you are pregnant, you should use Lumizyme only if your doctor has determined that its use outweighs any risks to your unborn child.
