CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Genzyme, a Sanofi company, announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has adopted a positive opinion recommending approval of Cerdelga® (eliglustat) capsules, an oral treatment for certain adults living with Gaucher disease type 1.
The European Commission (EC) is expected to make a final decision on granting marketing authorization for Cerdelga in the EU in the coming months. Cerdelga was approved by the U.S. Food and Drug Administration in August, and is under review by other regulatory authorities around the world.
"Today's CHMP opinion is the next step in ensuring that Cerdelga is available to eligible adults with Gaucher disease type 1 living in the European Union," said David Meeker, MD, Genzyme President and CEO. "The standard of care for Gaucher disease is Cerezyme® (imiglucerase for injection). With the availability of an effective oral therapy, Cerdelga would offer some patients and their physicians more choice in how to manage this serious disease."
The CHMP opinion was based on data from the Cerdelga clinical development program, which is the largest ever conducted in Gaucher disease, with approximately 400 patients treated in 29 countries. Genzyme has been researching an oral therapy for Gaucher disease for fifteen years.
The most common adverse reactions (greater than or equal to 10%) are fatigue, headache, nausea, diarrhea, back pain, pain in extremities, and upper abdominal pain.
About Gaucher Disease
Gaucher disease is an inherited condition affecting fewer than 10,000 people worldwide. People with Gaucher disease do not have enough of an enzyme, β-glucosidase (glucocerebrosidase) that breaks down a certain type of fat molecule. As a result, lipid engorged cells (called Gaucher cells) amass in different parts of the body, primarily the spleen, liver and bone marrow. Accumulation of Gaucher cells may cause spleen and liver enlargement, anemia, excessive bleeding and bruising, bone disease and a number of other signs and symptoms. The most common form of Gaucher disease, type 1, generally does not affect the brain.
About Genzyme's Gaucher Disease Program
Driven by a long-term commitment to meeting unmet needs in the Gaucher community, Genzyme has been researching and developing treatments for those living with Gaucher disease for over 20 years. The company's first approved therapy was the world's first treatment for Gaucher disease. A few years later, Genzyme developed a next-generation enzyme replacement therapy for Gaucher disease, which is now the standard of care with unmatched years of efficacy and safety data. In 2014, Genzyme was the first to bring to market a first-line oral treatment for Gaucher disease, providing a new treatment option for patients. Genzyme will continue to serve this community and remains committed to future advancements.
Cerdelga (eliglustat), a novel glucosylceramide analog given orally, was designed to partially inhibit the enzyme glucosylceramide synthase, which results in reduced production of glucosylceramide. Glucosylceramide is the substance that builds up in the cells and tissues of people with Gaucher disease. The concept was initially developed by the late Norman Radin, PhD, from the University of Michigan. In pre-clinical studies, the molecule, developed with James A. Shayman, MD, also from the University of Michigan, showed specificity for glucosylceramide synthase. Following an extensive pre-clinical and early clinical research program, Cerdelga was studied in the largest Phase 3 clinical program ever conducted in Gaucher disease.
IMPORTANT SAFETY INFORMATION
Indications and Usage
CERDELGATM (eliglustat) capsules are indicated for the long-term treatment of adults with Gaucher disease type 1 (GD1) who are CYP2D6 extensive metabolizers (EMs), intermediate metabolizers (IMs), or poor metabolizers (PMs) as detected by an FDA-cleared test. Patients who are CYP2D6 ultra-rapid metabolizers (URMs) may not achieve adequate concentrations of CERDELGA to achieve a therapeutic effect. A specific dose cannot be recommended for those patients whose CYP2D6 genotype cannot be determined (indeterminate metabolizers).
Important Safety Information
CERDELGA is contraindicated in the following patients due to the risk of significantly increased CERDELGA plasma concentrations which may result in prolongation of the PR, QTc, and/or QRS cardiac intervals that could result in cardiac arrhythmias: EMs or IMs taking a strong or moderate CYP2D6 inhibitor concomitantly with a strong or moderate CYP3A inhibitor and IMs or PMs taking a strong CYP3A inhibitor.
Drugs that inhibit CYP2D6 and CYP3A may significantly increase the exposure to CERDELGA; Cerdelga dose adjustment may be needed, depending on metabolizer status. See section 7 of the full Prescribing Information for more details and other potentially significant drug interactions.
Because CERDELGA is predicted to cause increases in ECG intervals at substantially elevated plasma concentrations, use is not recommended in patients with pre-existing cardiac disease, long QT syndrome, or in combination with Class IA and Class III antiarrhythmic medications.
The most common adverse reactions (≥10%) for CERDELGA are: fatigue, headache, nausea, diarrhea, back pain, pain in extremities, and upper abdominal pain.
Only administer CERDELGA during pregnancy if the potential benefit justifies the potential risk; based on animal data, CERDELGA may cause fetal harm. Discontinue drug or nursing based on importance of drug to mother. CERDELGA is not recommended in patients with moderate to severe renal impairment or in patients with hepatic impairment.

Cerezyme Important Safety Information
Approximately 15% of patients have developed IgG antibodies to Cerezyme during the first year of therapy. Approximately 46% of patients with detectable IgG antibodies experienced symptoms of hypersensitivity, and these patients have a higher risk of hypersensitivity. It is suggested that patients be monitored periodically for IgG antibody formation during the first year of treatment.
Hypersensitivity has also been observed in patients without detectable IgG antibodies. Symptoms suggestive of hypersensitivity have been noted in approximately 6.6% of all patients, and anaphylactoid reactions in less than 1%. Treatment with Cerezyme should be approached with caution in patients who have exhibited hypersensitivity symptoms such as pruritus, flushing, urticarial, angioedema, chest discomfort, dyspnea, coughing, cyanosis, and hypotension. Pre-treatment with antihistamines and/or corticosteroids and a reduced rate of infusion may allow continued treatment in most patients.
In less than 1% of patients, pulmonary hypertension and pneumonia have been observed during treatment with Cerezyme. These are known complications of Gaucher disease regardless of treatment. Patients with respiratory symptoms in the absence of fever should be evaluated for the presence of pulmonary hypertension.
Approximately 13.8% of patients have experienced adverse events related to treatment with Cerezyme. Some of these are injection site reactions such as discomfort, pruritus, burning, swelling or sterile abscess at the site at the site of venipuncture. Additional adverse reactions that have been reported include nausea, abdominal pain, vomiting, diarrhea, rash, fatigue, headache, fever, dizziness, chills, backache, and tachycardia. Transient peripheral edema has also been reported for this therapeutic class of drug.
