IMPOYZ vs ZUSDURI
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IMPOYZ is a monoclonal antibody that binds to and inhibits the activity of interleukin-23 (IL-23), a cytokine involved in inflammatory and immune responses. By blocking IL-23, it reduces the production of pro-inflammatory cytokines and attenuates the inflammatory cascade.
ZUSDURI is a small molecule inhibitor of Janus kinase 1 (JAK1) and Janus kinase 2 (JAK2), reducing signaling of pro-inflammatory cytokines.

Terminal elimination half-life 6–8 hours in adults with normal renal function; prolonged to 15–30 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 (70–80% as unchanged drug via glomerular filtration and tubular secretion); biliary/fecal (15–20%) with minor hepatic metabolism.
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.
