LYSODREN vs TAZVERIK
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Adrenocorticolytic agent; causes adrenal cortical necrosis and suppresses adrenal steroidogenesis, especially glucocorticoids and mineralocorticoids.
TAZVERIK is a histone methyltransferase EZH2 inhibitor. It selectively inhibits the enzymatic activity of EZH2, leading to decreased trimethylation of lysine 27 on histone H3 (H3K27me3), which results in reactivation of silenced genes and inhibition of proliferation in EZH2-mutant or wild-type cells.
Oral, initial dose 2-6 g/day divided in 3-4 doses, increase gradually to 8-10 g/day. Maximum dose 18 g/day.
600 mg orally twice daily, with or without food, for advanced epithelioid sarcoma. Continue until disease progression or unacceptable toxicity.

18-159 days; clinical context: during chronic therapy, steady-state may not be reached for 3-6 months.
Terminal elimination half-life is approximately 3.6 hours (range 1.6–7.1 hours) in patients with epithelioid sarcoma at steady state. Short half-life supports twice-daily dosing. Consider accumulation with renal or hepatic impairment.
Primarily renal excretion of metabolites; about 10% as unchanged drug. Biliary/fecal excretion accounts for <5%.
Primarily hepatobiliary excretion: approximately 70% of the dose recovered in feces as unchanged drug and metabolites, with <1% excreted renally as unchanged tazemetostat.
