"The approval of ELELYSO to treat pediatric patients with Type 1 Gaucher disease provides physicians another treatment option for this rare and potentially debilitating disease," said
The safety and efficacy of ELELYSO were assessed in fourteen pediatric patients with Type 1 Gaucher disease in two clinical trials. The first trial consisted of nine patients in a 12-month, multi-center, double-blind, randomized study in treatment-naive patients aged two to 13 years. At the end of the 12-month study, therapeutic efficacy of ELELYSO was demonstrated, as measured by a decrease in spleen and liver volume and an increase in platelet count. A second trial consisted of 5 pediatric patients aged 6 to 16 years who were switched from imiglucerase to ELELYSO. The trial was a 9-month, multi-center, open-label, single-arm study in patients who had been receiving treatment with imiglucerase at dosages ranging from 9.5 units/kg to 60 units/kg every other week for a minimum of 2 years. ELELYSO was administered for 9 months at the same dose as each patient's previous imiglucerase dose. If needed, adjustment of dosage was allowed during the study in order to maintain stability of clinical parameters. Mean spleen and liver volume, platelet count and hemoglobin value remained stable through 9 months of ELELYSO treatment.
The recommended dosage of ELELSYO for treatment-naive adult and pediatric patients four years of age and older is 60 units per kg of body weight administered every other week as a 60 to 120 minute intravenous infusion.
Patients previously treated on a stable dosage of imiglucerase are recommended to begin treatment with ELELYSO at that same dosage when they switch from imiglucerase to ELELYSO. Dosage adjustments can be made based on achievement and maintenance of each patient's therapeutic goals.
Serious hypersensitivity reactions, including anaphylaxis, have occurred in some patients treated with ELELYSO. The most common adverse reactions for ELELYSO in clinical trials were itching, flushing, headache, joint pain, pain in extremity, abdominal pain, vomiting, fatigue, back pain, dizziness, nausea and rash. Vomiting occurred more often in pediatric patients than adults.
"While Type 1 Gaucher disease can manifest in childhood or adulthood, the disease more often presents during childhood," said Paige Kaplan, MB, BCh, Section of Biochemical Genetics (Metabolic Diseases), Children's Hospital of

INDICATION ELELYSO™ is indicated for long-term enzyme replacement therapy (ERT) for adult and pediatric patients with a confirmed diagnosis of Type 1 Gaucher disease. IMPORTANT SAFETY INFORMATION Serious hypersensitivity reactions including anaphylaxis have occurred in some patients treated with ELELYSO (taliglucerase alfa) for injection, for intravenous use. When treated with ELELYSO your doctor should monitor you before and after infusion for reactions.
Medical support should be readily available when ELELYSO is given. Discontinue ELELYSO immediately if you show signs or symptoms of anaphylaxis during infusion and get immediate medical care. Signs and symptoms of anaphylaxis included hives, low blood pressure, flushing, wheezing, chest tightness, nausea, vomiting and dizziness.
Signs and symptoms of hypersensitivity included itching, swelling under the skin, flushing, redness, rash, nausea, vomiting, cough, chest tightness and throat irritation. These reactions occurred up to 3 hours after the start of infusion.
Management of hypersensitivity reactions is based on the severity of the reaction. Your doctor may manage the reactions by slowing or temporarily stopping the infusion, and/or treating with medications such as an antihistamine, a fever reducer and/or corticosteroids for mild reactions. Treatment with antihistamines and/or corticosteroids prior to infusion with ELELYSO may prevent these reactions from reoccurring. If severe hypersensitivity reactions occur, immediately stop the infusion of ELELYSO and get immediate medical care.
You should be carefully re-evaluated for treatment with ELELYSO if serious or hypersensitivity reactions including anaphylaxis occur.
The most common adverse reactions for ELELYSO are itching, flushing, headache, joint pain, pain in extremity, abdominal pain, vomiting, fatigue, back pain, dizziness, nausea and rash. Vomiting occurred more often in children than adults.
The recommended dosage of ELELYSO for adults and children who are 4 years of age and older and not taking another ERT is 60 units per kg of body weight given every other week as a 60 to 120 minute intravenous infusion.
As with all therapeutic proteins, including (enzyme replacement therapy) ERTs, there is a possibility of developing antibodies to ELELYSO. The relationship between developing antibodies and hypersensitivity reactions is not clear. Your doctor should monitor you for antibodies to ELELYSO if you have developed antibodies or if you have experienced hypersensitivity reactions to ELELYSO or other ERTs.
If you are pregnant, or plan to become pregnant, you should talk to your doctor about potential benefits and risks.
