KOGLUCOID vs MYOZYME
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
KOGLUCOID (velaglucerase alfa) is a recombinant form of human glucocerebrosidase, which catalyzes the hydrolysis of glucocerebroside to glucose and ceramide. It replaces the deficient enzyme in patients with Gaucher disease, reducing accumulation of glucocerebroside in macrophages.
Alglucosidase alfa is a recombinant form of human acid alpha-glucosidase (GAA) that hydrolyzes glycogen to glucose in lysosomes. It replaces deficient GAA enzyme activity in patients with Pompe disease.
60 U/kg intravenously over 4 hours every 2 weeks.

Terminal elimination half-life is approximately 15-30 minutes (range 11-35 min) in plasma after IV infusion. Short half-life necessitates frequent dosing (every 2 weeks). This reflects rapid clearance via receptor-mediated uptake into macrophages.
The terminal elimination half-life of alglucosidase alfa is approximately 2.3 hours at steady state. This short half-life necessitates weekly intravenous infusions to maintain therapeutic enzyme levels in target tissues.
KOGLUCOID (velaglucerase alfa) is a recombinant human glucocerebrosidase used for Gaucher disease. It is a protein therapeutic; elimination occurs via catabolism (proteolysis) to small peptides and amino acids. No significant renal or biliary excretion of intact drug. <1% excreted unchanged in urine.
Renal elimination is the primary route of clearance for alglucosidase alfa. Following intravenous administration, the drug is cleared via catabolism into small peptides and amino acids, which are then excreted renally. Less than 5% of the administered dose is excreted unchanged in urine. Biliary/fecal elimination is negligible.
