ELAHERE vs PADCEV
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.
Enfortumab vedotin is an antibody-drug conjugate (ADC) directed against Nectin-4, a cell adhesion molecule expressed on urothelial carcinoma cells. The antibody portion binds to Nectin-4, leading to internalization and release of the microtubule-disrupting agent monomethyl auristatin E (MMAE) via proteolytic cleavage. MMAE binds to tubulin and inhibits microtubule polymerization, inducing G2/M phase arrest and apoptosis.
6 mg/kg adjusted ideal body weight intravenously every 3 weeks until disease progression or unacceptable toxicity.
1.25 mg/kg (up to 125 mg) intravenously on days 1, 8, and 15 of a 28-day cycle

Terminal half-life approximately 6.2 days (range 3.7-9.5 days) after IV administration; supports every-3-week dosing interval.
Approximately 3.4 days (range 2.8-4.2 days) at steady state, supporting every-3-week dosing. Terminal half-life consistent with IgG1 clearance.
Fecal (approximately 80%) as unchanged drug; renal (approximately 8%) as unchanged drug and metabolites.
Primarily metabolized via catabolism into small peptides and amino acids; minimal renal excretion (<5% unchanged drug in urine). No biliary/fecal data available.
