IMULDOSA vs MEPSEVII
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Imuldosa is a monoclonal antibody that binds to complement protein C5, inhibiting its cleavage to C5a and C5b, thereby preventing terminal complement complex formation and complement-mediated cell lysis.
MEPSEVII (vestronidase alfa) is a recombinant form of human beta-glucuronidase that hydrolyzes accumulated glycosaminoglycans (GAGs) in lysosomes, restoring enzymatic activity in patients with Mucopolysaccharidosis VII (Sly syndrome).
1000 mg intravenously over 90 minutes every 4 weeks.
1 mg/kg administered intravenously once weekly over 4 hours.

Terminal elimination half-life is 27-33 hours in adults with normal renal function; prolongs to >50 hours in severe renal impairment (CrCl <30 mL/min).
Terminal elimination half-life: 9.4 hours (range 6.3–16.6 hours) in patients with mucopolysaccharidosis VII; supports weekly intravenous dosing.
Primarily renal excretion as unchanged drug (60-70%) and metabolites (15-20%); biliary/fecal elimination accounts for 10-15%.
Renal: negligible; primarily catabolized via peptide hydrolysis to amino acids, which are recycled or excreted in urine as metabolites.
