General information

Class/mechanism: FLT3 inhibitor, tyrosine kinase inhibitor (TKI). Midostaurin or its active metabolites CGP62221 and CGP52421 inhibit activity of wild type FLT3, FLT3 mutant kinases (ITD and TKD), KIT (wild type and D816V mutant), PDGFRα/β, VEGFR2, and members of the serine/threonine kinase PKC (protein kinase C) family. Midostaurin induced apoptosis in leukemic cells expressing ITD and TKD mutant FLT3 receptors or overexpressing wild type FLT3 and PDGF receptors. Midostaurin also causes apoptosis in mast cells and inhibits histamine release, proliferation, and KIT signaling.[1][2][3]
Route: PO
Extravasation: n/a

For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.[1]
