A Safety and Efficacy Study of Two Dose Levels of Taliglucerase Alfa in Pediatric Subjects With Gaucher Disease
A Multicenter, Double-blind, Randomized Safety and Efficacy Study of Two Dose Levels of Taliglucerase Alfa in Pediatric Subjects With Gaucher Disease
This is a multi-center, double-blind trial to assess the safety and efficacy of taliglucerase alfa in untreated subjects (2 to <18 years old) with Gaucher disease randomly assigned to treatment with one of two doses, 30 or 60 units/kg. Subjects will receive an intravenous (IV) infusion of taliglucerase alfa every two weeks. The total duration of treatment will be 12 months. At the end of the 12-month treatment period eligible subjects will be offered enrollment in an open-label extension study if taliglucerase alfa is not commercially available.

Inclusion Criteria:

  • Males and females 2 to <18 years old.
  • Diagnosis of Gaucher disease with leukocyte acid β-glucosidase activity ≤30% of the mean of the reference range for healthy subjects.
  • Subjects who have not received enzyme replacement therapy (ERT) in the past or who have not received ERT in the past 12 months and have a negative anti-glucocerebrosidase antibody assay.
  • Subjects who have not received substrate reduction therapy (SRT) in the past 12 months.
  • Subjects whose clinical condition, in the opinion of the investigator, requires treatment with enzyme replacement therapy (ERT).

Exclusion Criteria:

  • Currently taking another investigational drug for any condition.
  • Presence of neurological signs and symptoms characteristic of Gaucher disease with complex neuronopathic features other than longstanding oculomotor gaze palsy.
  • Presence of unresolved anemia due to iron, folic acid, or vitamin B12 deficiency
  • Previous hypersensitivity reaction to Cerezyme® (imiglucerase) or Ceredase® (alglucerase).
  • History of allergy to carrots.
  • Presence of HIV, HBsAg or hepatitis C infections.
  • Subject's parent(s) or legal guardian(s) are unable to understand the nature, scope and possible consequences of the study.
