Brief Summary:

Gaucher disease, the most prevalent lysosomal storage disorder, is caused by mutations in the human glucocerebrosidase gene (GCD)leading to reduced activity of the lysosomal enzyme glucocerebrosidase and thereby to the accumulation of substrate glucocerebroside (GlcCer)in the cells of the monocyte-macrophage system.

This is the first trial to utilize a recombinant active form of lysosomal enzyme, glucocerebrosidase, (human prGCD)which is expressed and purified in a bioreactor system from transformed carrot plant root cell line.

Exclusion Criteria:

  1. Have clinical evidence of any active significant disease that could potentially compromise the ability of the investigator to evaluate or interpret the effects of the study treatment on safety assessment and thus increase the risk to the subject to unacceptable levels.
