Dosages

Enzyme replacement therapy (ERT) in lysosomal acid lipase (LAL) deficiency
  • Intravenous
    • 0 years up to 18 years
      • Neonates and Infants 0-6 months with rapid disease progression:
        Start: 1-3 mg/kg/dose once a week.
        Higher starting dose may be considered based on severity of disease and rapid progression. In case of suboptimal clinical response dose can be further increased to 5 mg/kg/dose. Doses higher than 7.5 mg/kg/dose have not been studied.

        Infants and children without rapid disease progression before 6 months of age:
        1 mg/kg/dose once every 2 weeks. In case of suboptimal response, increase to 3 mg/kg/dose

Side effects in children

Infants (< 6 months).

Very common (> 10%): anaphylactic reaction, hypersensitivity (including irritability, agitation, vomiting, urticaria, eczema, itching and pallor). Eyelid edema. Tachycardia. Shortness of breath. Diarrhea. (Maculopapular) skin rash. Hyperthermia, fever. Presence of drug-specific antibody, decrease in oxygen saturation, increase in blood pressure, heart rate and respiratory rate.


Children 

Very common (> 10%): hypersensitivity (including chills, eczema, laryngeal edema, nausea, itching and urticaria). Dizziness. Abdominal pain, diarrhea. Fatigue, fever.
Common (1-10%): anaphylactic reaction. Transient hypercholesterolemia and hypertriglyceridemia. Tachycardia. Hyperemia, hypotension. Dyspnea. Abdominal distention. (Papulomatous) skin rash. Borstongemia, reaction at infusion site (including extravasation, pain and urticaria at infusion site).
Anaphylaxis can occur during infusion for up to 1 year after initiation of treatment. Most hypersensitivity reactions occur during or within 4 hours of infusion.
The development of antibodies to sebelipase alfa is observed more frequently in infants compared with children and adults. Presence of inhibitory antibody activity has been demonstrated in 58% of infants.
