Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant human glucocerebrosidase; hydrolyzes glucocerebroside to glucose and ceramide, reducing accumulated glucocerebroside in lysosomes of macrophages.
VIMIZIM (elosulfase alfa) is a recombinant human N-acetylgalactosamine-6-sulfatase that hydrolyzes the sulfate ester bond at position 6 of N-acetylgalactosamine in chondroitin sulfate and keratan sulfate, thereby reducing glycosaminoglycan (GAG) accumulation in patients with Morquio A syndrome (mucopolysaccharidosis IVA).
60 U/kg administered intravenously over 60 minutes every 2 weeks.
2 mg/kg administered intravenously once weekly over approximately 4 hours. Pretreat with antihistamines and antipyretics 30-60 minutes prior to infusion.

Mean terminal elimination half-life ranges from 6.1 to 8.9 minutes after intravenous infusion; rapid clearance due to receptor-mediated uptake.
Terminal elimination half-life approximately 9.8 days (range 7.7–13.8 days) in patients with mucopolysaccharidosis VI (MPS VI). Long half-life supports weekly intravenous dosing.
Primarily catabolized via peptide hydrolysis; renal excretion of small peptide fragments and amino acids; less than 1% excreted unchanged in urine.
Primarily renal. No specific data on biliary or fecal elimination; as a recombinant enzyme, likely catabolized to peptides and amino acids, with renal excretion of metabolites.
