KOGLUCOID vs VPRIV
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.
VPRIV (velaglucerase alfa) is a recombinant form of human lysosomal glucocerebrosidase that hydrolyzes glucocerebroside to glucose and ceramide, replacing the deficient enzyme in Gaucher disease.

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.
Terminal elimination half-life is approximately 30 minutes (range 15-60 minutes) in Gaucher disease patients, necessitating intravenous infusion over 1-2 hours every other week.
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.
Primarily metabolized via peptide hydrolysis; elimination is predominantly non-renal. Renal excretion accounts for <5% of the dose as intact drug. Fecal elimination of metabolites is negligible.
