NEW YORK &. CARMIEL, Israel–(BUSINESS WIRE)–Pfizer Inc. (NYSE:PFE) and Protalix BioTherapeutics, Inc. (NYSE-MKT:PLX,
TASE:PLX) announced today that the U.S. Food and Drug Administration
(FDA) approved ELELYSO™ (taliglucerase alfa) for injection for paediatric
patients. ELELYSO is therefore now indicated for long-term enzyme
replacement therapy (ERT) for adult and paediatric patients with a
confirmed diagnosis of Type 1 Gaucher disease.
“The approval of ELELYSO to treat paediatric patients with Type 1 Gaucher
disease provides physicians another treatment option for this rare and
potentially debilitating disease,” said Rory O’Connor, Senior Vice
President, Global Medical Affairs, Global Innovative Pharma Business,
Pfizer Inc. “This paediatric 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 paediatric
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-naïve 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
paediatric 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'd 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 haemoglobin value remained
stable through 9 months of ELELYSO treatment.
The recommended dosage of ELELSYO for treatment-naïve adult and
paediatric 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
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 paediatric
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 Philadelphia. “it's important that children with
this disease have access to a range of FDA-approved treatment options
that are effective.”
As part of its ongoing commitment to helping address the unmet medical
needs of people with rare diseases, Pfizer also offers a specialized
support program —. Called Gaucher Personal Support (GPS) —. People
living with Gaucher disease. Pfizer GPS is a one-stop resource for
personalized patient support and speciality pharmacy services for
patients and healthcare professionals. Pfizer GPS employs a dedicated
and caring team of healthcare specialists who are available to help
patients with Gaucher disease and their caregivers with reimbursement
assistance, coordinating and locating infusion services and ongoing
pharmacy support. Using Pfizer GPS, patients and healthcare
professionals can access all support services 24/7 using one toll-free
phone number, 1-855-ELELYSO (1-855-353-5976).
ELELYSO for injection is supplied as 200 units per vial and is available
by prescription only.

IMPORTANT SAFETY INFORMATION
Serious hypersensitivity reactions including anaphylaxis have occurred
in some patients treated with ELELYSO (taliglucerase alfa) for
injection. 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.

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.

body weight given every other week as a 60 to 120 minute intravenous
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 isn't clear. Your doctor should monitor you for antibodies to
ELELYSO if you've developed antibodies or if you've experienced
hypersensitivity reactions to ELELYSO or other ERTs.
If you're pregnant. Plan to become pregnant, you should talk to your
