IMULDOSA vs ZUSDURI
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.
ZUSDURI is a small molecule inhibitor of Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2), reducing signaling of pro-inflammatory cytokines.
1000 mg intravenously over 90 minutes every 4 weeks.
200 mg orally once daily, with or without food.

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).
The terminal elimination half-life is approximately 12–15 hours in healthy adults, supporting twice-daily dosing. In patients with hepatic impairment, half-life may be prolonged up to 24 hours, requiring dose adjustment.
Primarily renal excretion as unchanged drug (60-70%) and metabolites (15-20%); biliary/fecal elimination accounts for 10-15%.
ZUSDURI is primarily eliminated via hepatic metabolism with subsequent biliary excretion. Approximately 30% of the dose is excreted unchanged in feces, and less than 5% is recovered unchanged in urine. The major metabolites are excreted in bile and eliminated in feces.
