Обзор

This is a prospective, multicenter, phase Ⅱ study consisting of dose escalation and ex-pansion stages in unfit newly diagnosed AML.

Подробное описание

This is a prospective, multicenter, phase Ⅱ study consisting of dose escalation and ex-pansion stages in unfit newly diagnosed AML. Patients in dose escalation stage received oral MAX-40279 at three doses, in combination with VEN and AZA in 28-day cycles. Three to six patients were enrolled at each dose level. The dose limiting toxicities (DLTs) observation period was 28 days after the first dose. All evaluable patients with ≥1 cycle treatment were included in preliminary efficacy analysis.
