Eligibility Criteria
Inclusion Criteria:
Includes:

Exclusion Criteria:
Includes:

- The participant has received treatment with any investigational drug or device within the 30 days prior to study entry; such use during the study is not permitted
- Participant is HIV positive
- Participant is hepatitis B/C positive
- The participant presents with sustained iron, folic acid and/or vitamin B12 deficiency-related anemia during Screening
- The participant, participant's parent(s), or participant's legal guardian(s) is/are unable to understand the nature, scope, and possible consequences of the study
- The participant has a significant comorbidity that might affect study data or confound the study results
- The participant is unable to comply with the protocol or is otherwise unlikely to complete the study, as determined by the Investigator
- The participant has experienced an anaphylactic/anaphylactoid reaction during treatment with imiglucerase

Outcomes
Primary Outcome Measures
Participants Who Experienced at Least One Adverse Event
Safety was assessed throughout the study by assessments including adverse events, concomitant medication use, and vital signs. Additional safety assessments, including 12-lead ECGs, physical examinations, clinical laboratory tests and determination of the presence of anti-velaglucerase alfa antibodies. Refer to Adverse event section for further details.
Secondary Outcome Measures

5. Study Description
Brief Summary
Gaucher disease is a rare lysosomal storage disorder caused by the deficiency of the enzyme glucocerebrosidase (GCB). Due to the deficiency of functional GCB, glucocerebroside accumulates within macrophages leading to cellular engorgement, organomegaly, and organ system dysfunction. The purpose of this study is to evaluate the safety and efficacy of every other week dosing of GA-GCB (velaglucerase alfa) in participants with type 1 Gaucher disease who were previously treated with imiglucerase.
Detailed Description
Type 1 Gaucher disease, the most common form, accounts for more than 90% of all cases and does not involve the CNS. Typical manifestations of type 1 Gaucher disease include hepatomegaly, splenomegaly, thrombocytopenia, bleeding tendencies, anemia, hypermetabolism, skeletal pathology, growth retardation, pulmonary disease, and decreased quality of life. Gene-Activated® human glucocerebrosidase (GA-GCB; velaglucerase alfa) is produced in a continuous human cell line using proprietary gene-activation technology and has an identical amino acid sequence to the naturally occurring human enzyme. GA-GCB contains terminal mannose residues that target the enzyme to the macrophages-the primary target cells in Gaucher disease. This study was designed to determine the safety of GA-GCB in men, women, and children with Type 1 Gaucher disease who were previously treated with imiglucerase. Each participant's duration of treatment will be 12 months.
