Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Recombinant human α-galactosidase A enzyme that hydrolyzes globotriaosylceramide (Gb3) and other glycosphingolipids with terminal α-galactosyl groups, thereby reducing accumulation in tissues.
Recombinant adenosine deaminase (ADA) enzyme replacement therapy; degrades adenosine and deoxyadenosine, reducing toxic metabolites and restoring immune function.
1 mg/kg intravenously over 2 hours every 2 weeks.
25 mg/kg body weight administered intramuscularly once weekly.

Terminal elimination half-life approximately 0.5–1 hour; short half-life necessitates twice-weekly intravenous dosing.
Terminal elimination half-life is approximately 3-6 months (mean ~100 days) in patients with PEG-ADA deficiency; clinical context: sustained enzyme replacement allows weekly or biweekly dosing.
Primarily eliminated via renal excretion as intact protein; minimal biliary/fecal elimination (<1%).
Renal excretion of unchanged drug and metabolites: approximately 100% eliminated renally; no significant biliary/fecal elimination.
