For Healthcare Professionals

Applies to galsulfase: intravenous solution

General

During a double-blind, placebo-controlled trial, 19 patients received galsulfase (the active ingredient contained in Naglazyme) and 20 patients received placebo. Serious side effects included apnea, pyrexia, and respiratory distress. Severe side effects included chest pain, dyspnea, laryngeal edema, and conjunctivitis.

During 4 open-label clinical trials, common side effects included pruritus, urticaria, pyrexia, headache, nausea, and vomiting. Serious side effects included laryngeal edema, urticaria, angioedema, and other allergic reactions. Severe side effects included urticaria, rash, and abdominal pain.

During each trial, the most common side effects requiring interventions were infusion reactions.

Other

Infusion reactions have been reported as early as the first week and as late as the 146th week of galsulfase (the active ingredient contained in Naglazyme) therapy.

Infusion reaction symptoms generally abated with slowing or temporary interruption of the infusion along with administration of additional antihistamines, antipyretics, and occasionally corticosteroids. Most patients were able to complete their infusions. Subsequent infusions were managed with a slower rate of galsulfase administration and treatment with additional prophylactic antihistamines. In patients who had more severe reactions, treatment included prophylactic corticosteroids.

Other side effects have included abdominal pain (47%), ear pain (42%), pain (32%), chills/rigors (21%), chest pain (16%), malaise (11%), umbilical hernia (11%), pyrexia, and facial edema. Infusion reactions (some severe) have been reported in 56% of patients despite routine pretreatment with antihistamines. Serious symptoms reported during infusion have included angioedema, laryngeal edema, pyrexia, anaphylactoid reaction, respiratory distress, apnea, and urticaria. Severe symptoms of infusion reactions have included chest pain, dyspnea, apnea, laryngeal edema, conjunctivitis, rash, and urticaria. The most common infusion reaction symptoms have included pyrexia, chills, rash, urticaria, dyspnea, nausea, vomiting, pruritus, erythema, hypertension, abdominal pain, and headache. Symptoms of infusion reactions have also included respiratory distress, chest pain, hypotension, angioedema, conjunctivitis, tremor, cough, retrosternal pain, and joint pain. Recurrent infusion reactions have been reported in 70% of patients during multiple infusions, but not always in consecutive weeks. Serious reactions occurring during galsulfase infusion (including anaphylaxis, shock, hypotension, bronchospasm, and respiratory failure) have been reported during postmarketing experience. Additional infusion reactions (including pyrexia, erythema, pallor, bradycardia, tachycardia, hypoxia, cyanosis, tachypnea, and paresthesia) have been reported during postmarketing experience.

Hypersensitivity

Hypersensitivity side effects have included anaphylaxis and severe allergic reactions. Some reactions have been life-threatening and have included anaphylaxis, shock, respiratory distress, dyspnea, bronchospasm, laryngeal edema, and hypotension. Angioedema and other allergic reactions (unspecified) have been reported.

Respiratory

Respiratory side effects have included dyspnea (21%), pharyngitis (11%), nasal congestion (11%), apnea, respiratory distress, and laryngeal edema. Acute respiratory complications associated with administration have been reported.

Musculoskeletal

Musculoskeletal side effects have included arthralgia (42%).

Dermatologic

Dermatologic side effects have included rash (21%), pruritus, and urticaria.

Ocular

Cardiovascular side effects have included hypertension (11%). A risk of acute cardiorespiratory failure and the possible development of congestive heart failure have been reported.
