LAZCLUZE vs TZ-3
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
LAZCLUZE (lazertinib) is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) that irreversibly binds to and inhibits EGFR tyrosine kinase, including mutant forms with T790M resistance mutations and exon 19 deletions, thereby blocking downstream signaling pathways involved in tumor cell proliferation and survival.
(S)-3-(4-(2-((3-fluorophenyl)amino)-2-oxoethyl)piperazin-1-yl)-N,N-dimethylpropanamide; selectively inhibits the interaction between the PD-1/PD-L1 immune checkpoint, blocking the PD-1/PD-L1 pathway and restoring antitumor T-cell function.

The terminal elimination half-life of Lazcluze is approximately 24-30 hours, supporting once-daily dosing with steady-state achieved within 5-7 days.
12–18 hours (terminal). Steady-state achieved in ~3 days. Extended to ~30 hours in severe renal impairment.
Lazcluze is primarily eliminated via biliary excretion into feces, with approximately 70-80% of the administered dose recovered as unchanged drug in feces. Renal elimination accounts for less than 10% of the dose, with less than 1% excreted unchanged in urine.
Primarily renal (60–70% unchanged), with 20–30% biliary/fecal, and <10% metabolized. Dosage adjustment required in renal impairment.
