Pfizer Inc. (NYSE:PFE) today announced that the Orthodox Union (OU) has granted kosher certification to ELELYSO™ (taliglucerase alfa) for injection, an enzyme replacement therapy (ERT) for the long-term treatment of adults with a confirmed diagnosis of Type 1 Gaucher disease. ELELYSO is the first prescription medication to be certified kosher by the OU, a milestone for the brand which was approved by the U.S. Food and Drug Administration (FDA) in May 2012.

“Type 1 Gaucher disease is a rare disease, most frequently found among individuals of Ashkenazi Jewish descent, which has a significant impact on patients and their families,” said Rory O’Connor, Pfizer’s Senior Vice President, Head of Global Medical Affairs, Innovative Pharma Business. “This certification reflects Pfizer’s commitment to all patients suffering from Type 1 Gaucher disease.”

ELELYSO is an FDA-approved plant-based treatment option for Type 1 adult Gaucher patients that, in addition, meets the stringent standards of kosher regulation and inspections. The OU, the most recognized certifier of kosher products worldwide, inspected the Protalix Biotherapeutics  manufacturing facility in Israel in which ELELYSO is produced to ensure that the treatment met all applicable qualifications. The criteria were met due to Protalix’s innovative and proprietary manufacturing system which uses genetically engineered carrot cells grown in a simple solution of water, plant extracts, sugar, and a mixture of vitamins and minerals to produce ELELYSO.

“We are proud to grant kosher certification to ELELYSO. Gaucher disease and its treatment options are an important issue in the Jewish community, as one in 14 Ashkenazi Jews are carriers for the disease compared to the general population,” said Rabbi Menachem Genack, CEO of OU Kosher. “In a life or death situation, Jewish law clearly sets aside the kosher status of a prescription medicine, but in other cases, it is preferable and sometimes recommended that a medicine be certified kosher. We commend Pfizer for taking this step and making this commitment to the Jewish community.”

Protalix is the first Israeli biotech firm to partner with Pfizer Inc. ELELYSO is the first FDA-approved plant cell-based recombinant therapeutic protein.

“Protalix has a close connection and deep understanding of the Gaucher community,” said Shomrat Shurtz, Senior Director of lysosomal therapeutics products, Protalix. “This is yet another example to the strong commitment from both Pfizer and Protalix to Gaucher patients.”

Important Safety Information

As with any intravenous protein medicine, like enzyme replacement therapy (ERT), severe allergic reactions (including anaphylaxis) have been observed in patients treated with ELELYSO. If this occurs, ELELYSO should be immediately discontinued, and appropriate medical treatment should be initiated. Patients who have experienced anaphylaxis to ELELYSO or another ERT should proceed with caution upon retreatment.

In addition, infusion reactions (including allergic reactions) – defined as a reaction occurring within 24 hours of the infusion – were the most commonly observed reactions to ELELYSO. The most commonly observed infusion reactions were headache, chest pain or discomfort, weakness, fatigue, hives, abnormal redness of the skin, increased blood pressure, back or joint pain, and flushing. Other infusion or allergic reactions included swelling of the face, mouth, and/or throat; wheezing; shortness of breath; skin color turning blue; coughing; and low blood pressure. Most of these reactions were mild and did not require treatment.

Management of infusion reactions is based on the type and severity of the reaction. Your doctor may manage infusion reactions by temporarily stopping the infusion, slowing the infusion rate, or treating with medications such as an antihistamine and/or a fever reducer. Treatment with antihistamines and/or corticosteroids prior to infusion with ELELYSO may prevent these reactions.

Other common adverse reactions observed were upper respiratory tract infections, throat infection, flu, urinary tract infection, and pain in extremities.

As with all therapeutic proteins, including ERTs, there is a possibility of developing antibodies to ELELYSO. However, it is currently unclear whether this has an impact on the clinical response or adverse reactions. Patients with an immune response to other ERTs who are switching to ELELYSO should continue to be monitored for antibodies. Comparison of the frequency of antibodies across ERTs may be misleading. Patients who have developed infusion or immune reactions with ELELYSO or with another ERT should be monitored for antidrug antibodies when being treated with ELELYSO.

If you are pregnant, or plan to become pregnant, you should talk to your doctor about potential benefits and risks.
