LAZCLUZE vs WIDAPLIK
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.
WIDAPLIK is a small-molecule inhibitor of cyclin-dependent kinase 12 (CDK12). By selectively inhibiting CDK12, it interferes with the phosphorylation of RNA polymerase II, leading to reduced expression of DNA damage response genes and promoting apoptosis in cancer cells.
20 mg orally once daily with or without food.

The terminal elimination half-life of Lazcluze is approximately 24-30 hours, supporting once-daily dosing with steady-state achieved within 5-7 days.
Terminal elimination half-life is 12 hours (range 10–14 h) in healthy adults; prolonged to 24–36 h in moderate renal impairment (CrCl 30–50 mL/min).
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 excretion as unchanged drug (approximately 70%) with 20% as inactive metabolites; 10% via feces.
