CAMBRIDGE, Mass. -- (BUSINESS WIRE) -- Genzyme, a Sanofi company (EURONEXT: SAN and NYSE: SNY), today announced that the U.S. Food and Drug Administration (FDA) approved a supplement to expand the indication for Lumizyme® (alglucosidase alfa). Lumizyme manufactured at the 4000L scale is now indicated for all Pompe patients of any age or phenotype. The approval of this indication is now consistent with that of the rest of the world, where alglucosidase alfa manufactured at the 4000L is the only scale available. Previously, in the United States, Lumizyme had been approved only for patients with late onset Pompe disease.
“We are thankful to the entire Pompe community who has been on this journey to provide a sustainable, long-term option for Pompe patients in the United States,” said Genzyme President and CEO, David Meeker, M.D. “We are pleased we can now offer alglucosidase alfa produced at the 4000L scale to all patients in the US.”
In the United States, alglucosidase alfa is manufactured at two different production scales. Alglucosidase alfa manufactured at the 160L scale (initial pilot scale) has a brand name of Myozyme® (alglucosidase alfa) and alglucosidase alfa manufactured at the 4000L (final manufacturing scale) has a brand name of Lumizyme.
Based on the biochemical and clinical data provided as part of the submission, FDA concluded that alglucosidase alfa manufactured at both scales in the US (i.e., Lumizyme and Myozyme) are comparable. The overall safety profile of alglucosidase alfa remains unchanged.
Specific updates to the Lumizyme product label include:
Lumizyme, marketed as Myozyme outside of U.S., is approved in more than 65 countries. For the complete Lumizyme label, visit www.lumizyme.com.
About Pompe Disease
Pompe disease is a progressive, debilitating and often fatal neuromuscular disease caused by a genetic deficiency or dysfunction of the lysosomal enzyme acid alpha-glucosidase (GAA) affecting an estimated 1 in 40,000 people worldwide. This enzymatic defect results in the accumulation of glycogen primarily in muscle tissues that leads to muscle weakness, loss of respiratory function, and often premature death. Absent treatment, when symptoms occur in infancy, babies typically die within the first year of life. When symptoms occur in childhood or adulthood, patients often lose their ability to walk and require wheelchairs to assist with mobility and experience difficulty breathing as well as mechanical ventilation to breathe.
Important Safety Information for Lumizyme and Myozyme
LUMIZYME® (alglucosidase alfa) is a hydrolytic lysosomal glycogen-specific enzyme indicated for patients with Pompe disease (acid α-glucosidase (GAA) deficiency).
IMPORTANT SAFETY INFORMATION
WARNING: RISK OF ANAPHYLAXIS, HYPERSENSITIVITY AND IMMUNE-MEDIATED REACTIONS, and RISK OF CARDIORESPIRATORY FAILURE
See full prescribing information for complete boxed warning.
Life-threatening anaphylactic reactions and severe hypersensitivity reactions, presenting as respiratory distress, hypoxia, apnea, dyspnea, bradycardia, tachycardia, bronchospasm, throat tightness, hypotension, angioedema (including tongue or lip swelling, periorbital edema, and face edema), and urticaria, have occurred in some patients during and after alglucosidase alfa infusions. Immune-mediated reactions presenting as proteinuria, nephrotic syndrome, and necrotizing skin lesions have occurred in some patients following alglucosidase alfa treatment. Closely observe patients during and after alglucosidase alfa administration and be prepared to manage anaphylaxis and hypersensitivity reactions. Inform patients of the signs and symptoms of anaphylaxis, hypersensitivity reactions, and immune-mediated reactions and have them seek immediate medical care should signs and symptoms occur.
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.
WARNINGS AND PRECAUTIONS
Anaphylaxis and Hypersensitivity Reactions: Life-threatening anaphylaxis and hypersensitivity reactions have been observed in some patients during and after treatment with alglucosidase alfa. If anaphylaxis or severe hypersensitivity reactions occur, immediately discontinue infusion and institute appropriate medical treatment.
Immune-Mediated Reactions: Monitor patients for the development of systemic immune-mediated reactions involving skin and other organs.
Risk of Acute Cardiorespiratory Failure: Patients with compromised cardiac or respiratory function may be at risk of acute cardiorespiratory failure. Caution should be exercised when administering alglucosidase alfa to patients susceptible to fluid volume overload.
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 alglucosidase alfa infusion.
Appropriate medical support and monitoring measures should be available during infusion.
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 (6.1).
USE IN SPECIFIC POPULATIONS
Pregnancy: Based on animal data, alglucosidase alfa may cause fetal harm.
