For Healthcare Professionals

Applies to laronidase: intravenous solution

General

The most frequently reported infusion reactions included pyrexia, chills, blood pressure, increased, tachycardia, and oxygen saturation decreased.

The most frequently reported adverse reactions included rash, upper respiratory tract infection, injection site reaction, hyperreflexia, paresthesia, flushing, and poor venous access.[Ref]

Hypersensitivity

Common (1% to 10%): Anaphylactic reaction[Ref]

Other

Very common (10% or more): Infusion reactions (up to 49%), pyrexia (up to 30%), otitis media (20%), chills (up to 20%), central venous catheterization required for infusion (15%), oxygen saturation decreased (up to 10%)
Common (1% to 10%): Chest pain, face edema, gravitational/dependent edema, abscess, feeling hot, feeling cold, influenza-like illness, body temperature increased
Frequency not reported: Laryngeal edema, extravasation
Postmarketing reports: Fatigue[Ref]

The most common adverse reactions were infusion reactions; the frequency decreased over time with continued use, and most were classified as mild to moderate in severity. The majority of infusion reactions requiring intervention were ameliorated with slowing of the infusion rate, temporarily stopping the infusion, with or without administering additional antihistamines and/or antipyretics.[Ref]

Gastrointestinal

Very common (10% or more): Nausea, abdominal pain/discomfort
Common (1% to 10%): Vomiting, diarrhea[Ref]

Immunologic

In clinical trials, 99 of 102 patients developed IgG antidrug antibodies. No correlation was demonstrated between presence of antidrug antibodies and therapeutic response or the occurrence of allergic reactions. There was also no consistent association between presence of antibodies that neutralize enzymatic activity and therapeutic response. The potential for antibody neutralization of cellular uptake has not been evaluated. There were 9 patients collectively in clinical studies who experienced severe infusion reactions and were subsequently tested for drug specific IgE antibodies and complement activation. Following testing, 1 of the 9 patients had an anaphylactic reaction consisting of urticaria and airway obstruction and tested positive for both drug specific IgE binding antibodies and complement activation. In a separate open-label study of patients 5 years and younger, none tested positive for IgE. The clinical significance of IgE antibodies has not been established.[Ref]

Very common (10% or more): Antidrug antibody development (97%)
Postmarketing reports: Anaphylactic shock, IgE antibody development, compliment activation[Ref]

Dermatologic

Very common (10% or more): Rash (up to 36%)
Common (1% to 10%): Angioedema, urticaria, pruritus, hyperhidrosis, alopecia, cold sweat
Frequency not reported: Erythema[Ref]

Local

Very common (10% or more): Injection site reaction (up to 18%)
Common (1% to 10%): Injection site pain[Ref]

Frequency not reported: Cyanosis
Postmarketing reports: Cardiorespiratory arrest, cardiac failure[Ref]

Nervous system

Very common (10% or more): Hyperreflexia (14%), paresthesia (14%), headache
Common (1% to 10%): Dizziness, tremor[Ref]

Hematologic

Common (1% to 10%): Thrombocytopenia[Ref]
