Overview

Elacytarabine + idarubicin is a combination therapy investigated for the treatment of relapsed or refractory acute myeloid leukemia (AML). Elacytarabine is a novel lipophilic nucleoside analogue and an elaidic acid ester derivative of cytarabine. It was designed to overcome resistance mechanisms associated with standard cytarabine therapy by enabling cell entry independent of the human equilibrative nucleoside transporter 1 (hENT1) and resisting deactivation by cytidine deaminase. Once inside cells, elacytarabine is metabolized to cytarabine and inhibits both DNA and RNA synthesis, leading to cell death[6][8]. Idarubicin is an anthracycline antineoplastic agent that intercalates into DNA and inhibits topoisomerase II activity, preventing DNA replication and repair[1]. The combination has shown clinical activity in patients with refractory AML in early-phase trials[3][7].
