HIDE SMILES / InChI
Lestaurtinib (CEP-701, KT-5555) is an orally bio-available polyaromatic indolocarbazole alkaloid derived from K-252a. Lestaurtinib is a multi-targeted tyrosine kinase inhibitor which has been shown to potently inhibit FLT3 at nanomolar concentrations in preclinical studies, leading to its rapid development as a potential targeted agent for treatment of AML. Phase I studies have shown lestaturtinib to be an active agent particularly when used in combination with cytotoxic drugs. Currently, Phase II and Phase III studies are underway aiming to establish the future of this agent as a treatment option for patients with FLT3-ITD AML.

Sample Use Guides

Induction chemotherapy with or without sequential treatment with oral Lestaurtinib (CEP-701) at 80 mg bid. For patients with duration of first CR of 1 to 6 months, the induction regimen will be MEC.
Route of Administration: Oral
Lestaurtinib (CEP-701) potently inhibits FLT3/ITD autophosphorylation with a half maximal inhibitory concentration (IC50) of approximately 2 nM. Inhibition of FLT3 to 15% of its baseline level of autophosphorylation (the level of inhibition required to induce a significant cytotoxic effect on FLT3-dependent cell lines) occurs at a concentration of roughly 5 uM.
