Condition(s) targeted: Gaucher Disease
Intervention: plant expressed recombinant human glucocerebrosidase (Drug)
Phase: Phase 3
Status: Not yet recruiting

Summary
This is a multi-center, open-label, switchover trial to assess the safety of prGCD in 15
patients with Gaucher disease who are currently being treated with imiglucerase (Cerezyme®)
ERT. Eligible patients will enter a 12-week Stability Evaluation Period to establish the
stability of their disease. Patients with stable disease will then be switched from their
imiglucerase treatment to receive intravenous (IV) infusions of prGCD every two weeks for a
total of 20 IV infusions. The dose of prGCD will be equal to each patient's previous
imiglucerase dose. The infusions will be administered at the selected investigational site
(clinic/hospital) At the end of the 9-month treatment period (20 visits, 38 weeks) eligible
patients will be offered enrollment in an open-label extension study.
