               -  GD-related readily palpable enlarged liver.

          -  Not received treatment for GD (investigational products, miglustat, velaglucerase
             alfa, or imiglucerase) within 12 months prior to study entry.

          -  Ability to comprehend and willing to sign the ICF.

          -  Legal guardian (and patient if age appropriate) understood the nature of the

          -  Female patients of childbearing potential must had agreed to use a medically
             acceptable method of contraception at all the times during the study. Male patients
             must have used a medically acceptable method of birth control throughout their
             participation in the study and were required to report the pregnancy of a partner.

        Exclusion Criteria:

          -  Type 2 or 3 GD.

          -  Splenectomy.

          -  Antibody positive to ISU302 or imiglucerase during screening or the patient had
             experienced an anaphylactic reaction to ISU302 or imiglucerase. - Treatment with any
             non-GD-related investigational drug or medical device within 30 days prior to study
             entry; such use during the study was also not permitted.

          -  Currently receiving red blood cell (RBC) growth factor (eg, erythropoietin) chronic

          -  Positive for human immunodeficiency virus (HIV) and hepatitis B or C.

          -  Exacerbated anemia at screening (due to iron, folic acid, or vitamin B12 deficiency or
             infectious/immune-mediated cause).

          -  Significant comorbidity(ies) that could affect study data or confounded the study
             results (eg, malignancies, primary biliary cirrhosis, autoimmune liver disease).

          -  Pregnant or lactating female patients and those not willing to use highly effective
