FDA Approves Pfizer's Gaucher Drug for Children

James Radke


Pfizer Inc. and Protalix BioTherapeutics, Inc. announced the U.S. Food and Drug Administration (FDA) has approved Elelyso (taliglucerase alfa) for injection in pediatric patients with a confirmed diagnosis of Type 1 Gaucher disease.

“This pediatric indication, along with the recent announcement that Elelyso received kosher certification by the Orthodox Union (OU), reinforces the ongoing commitment of Pfizer to addressing the needs of the Gaucher community.”

In a press release, Pfizer’s  Rory O’Connor, Senior Vice President, Global Medical Affairs, Global Innovative Pharma Business, stated, "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,” adding,  “This pediatric indication, along with the recent announcement that Elelyso received kosher certification by the Orthodox Union (OU), reinforces the ongoing commitment of Pfizer to addressing the needs of the Gaucher community.”

The safety and efficacy of Elelyso were assessed in fourteen pediatric patients with Type 1 Gaucher disease who were part of two clinical trials; a 12-month, multi-center, double-blind, randomized study in treatment-naïve patients that included children aged two to 13 years (n=9) and 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 then switching to Elelyso. That study included children aged 6 to 16 years (n=5).

According to the drug manufacturers,  the recommended dosage of Elelyso for treatment-naïve 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.

“It is important that children with this disease have access to a range of FDA-approved treatment options that are effective.”

The addition of the pediatric indication is welcome news.   Paige Kaplan, MB, BCh, Section of Biochemical Genetics (Metabolic Diseases), Children's Hospital of Philadelphia  stated “While Type 1 Gaucher disease can manifest in childhood or adulthood, the disease more often presents during childhood,” adding,  “It is important that children with this disease have access to a range of FDA-approved treatment options that are effective.”
