Clinical Trials And Postmarketing Experience

The following adverse reactions associated with the use of imiglucerase were identified in clinical studies or postmarketing reports. Because some of these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

System Organ Class Adverse Reactions
Nervous system disorders dizziness, headache
Cardiac disorders tachycardia
Vascular disorders cyanosis,* flushing,* hypotension*
Respiratory, thoracic and mediastinal disorders cough,* dyspnea,* pneumonia, pulmonary hypertension
Gastrointestinal disorders abdominal pain, diarrhea, nausea, vomiting
Immune system disorders anaphylaxis,* hypersensitivity
Skin and subcutaneous tissue disorders angioedema,* pruritus,* rash, urticaria*
Musculoskeletal and connective tissue disorders back pain
General disorders and administration site conditions chest discomfort,* chills, fatigue, infusion-site burning, infusion-site discomfort, infusion-site swelling, pyrexia
* Signs and symptoms suggestive of hypersensitivity and other infusion-associated reactions [see WARNINGS AND PRECAUTIONS].

Adverse reactions reported in pediatric patients 2 years of age and older were similar to adults.


As with all therapeutic proteins, there is potential for immunogenicity. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay. Additionally, the observed incidence of antibody (including neutralizing antibody) positivity in an assay may be influenced by several factors including assay methodology, sample handling, timing of sample collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies in the studies described below with the incidence of antibodies in other studies or to other imiglucerase products may be misleading.

Approximately 15% of patients treated and tested to date have developed IgG antibody to Cerezyme during the first year of therapy. Patients who developed IgG antibody did so largely within 6 months of treatment and rarely developed antibodies to Cerezyme after 12 months of therapy. Approximately 46% of patients with detectable IgG antibodies experienced symptoms of hypersensitivity. Patients with antibody to Cerezyme have higher risk of hypersensitivity reaction [see WARNINGS AND PRECAUTIONS]. Patients who developed IgG antibody to Cerezyme had increased elimination half-life compared to patients without antibody [see CLINICAL PHARMACOLOGY].
