ELAHERE vs KADCYLA
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.
KADCYLA (ado-trastuzumab emtansine) is an antibody-drug conjugate composed of trastuzumab, a humanized anti-HER2 antibody, linked to the microtubule inhibitor DM1 (maytansinoid). It binds to HER2 receptors on tumor cells, internalized via receptor-mediated endocytosis, and releases DM1 intracellularly, causing cell cycle arrest and apoptosis.
