IDVYNSO vs OSIMERTINIB MESYLATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
IDVYNSO is a selective dopamine D3 receptor antagonist, which modulates dopaminergic neurotransmission in the mesolimbic pathway.
Osimertinib is an irreversible epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor that selectively inhibits EGFR exon 19 deletion and L858R substitution mutations, as well as T790M resistance mutations, with less activity against wild-type EGFR.
5 mg/kg IV once daily for 14 days; then 2.5 mg/kg IV once daily for 14 days.
80 mg orally once daily, with or without food.

Terminal elimination half-life is 12–18 hours, supporting twice-daily dosing in patients with normal renal function.
Terminal elimination half-life is approximately 48 hours (range 36-60 h) based on population pharmacokinetic analysis, supporting once-daily dosing.
Renal excretion of unchanged drug accounts for approximately 60% of elimination; biliary/fecal excretion accounts for 30%, with the remainder metabolized.
Osimertinib is eliminated primarily via feces (67.8%, with 1.2% as unchanged drug) and urine (13.8%, with 0.8% as unchanged drug). The remainder is recovered as metabolites.
