ELAHERE vs JYLAMVO
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ELAHERE (mirvetuximab soravtansine) is an antibody-drug conjugate (ADC) targeting folate receptor alpha (FRα). It consists of a humanized anti-FRα antibody conjugated to the maytansinoid DM4, a microtubule inhibitor. Upon binding to FRα on tumor cells, the ADC is internalized and releases DM4, which binds to tubulin and disrupts microtubule polymerization, leading to cell cycle arrest and apoptosis.
JYLAMVO (methotrexate) is a folate analog that inhibits dihydrofolate reductase (DHFR), thereby disrupting DNA synthesis and repair. It also inhibits purine and thymidylate synthesis, leading to immunosuppressive and antineoplastic effects.
6 mg/kg adjusted ideal body weight intravenously every 3 weeks until disease progression or unacceptable toxicity.
Oral: 30 mg twice daily for adults with relapsed or refractory acute myeloid leukemia (AML) as a monotherapy.

Terminal half-life approximately 6.2 days (range 3.7-9.5 days) after IV administration; supports every-3-week dosing interval.
Terminal elimination half-life is 12-16 hours in adults with normal renal function; prolonged to 24-48 hours in severe renal impairment (CrCl <30 mL/min).
Fecal (approximately 80%) as unchanged drug; renal (approximately 8%) as unchanged drug and metabolites.
Primarily renal elimination as unchanged drug (approximately 70-80%) with minor biliary/fecal excretion (20-30%).
