Pharmacology
Ivosidenib is a small molecule inhibitor of the mutant isocitrate dehydrogenase 1 (IDH1) enzyme that reduces 2-hydroxyglutarate (2-HG) levels and induces myeloid differentiation in IDH1-mutated AML; in IDH1-mutated cholangiocarcinoma, it also reduces 2-HG levels in tumor tissue.
Gilteritinib is a small molecule inhibitor of multiple receptor tyrosine kinases, including FLT3; it inhibits FLT3 receptor signaling and proliferation in cells expressing FLT3-ITD and FLT3 tyrosine kinase domain mutations, and induces apoptosis in leukemic cells expressing FLT3-ITD.
