Clinical Trial Summary

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of Clifutinib Besylate in Relapsed/refractory AML patients with FLT3-ITD mutation.

Description:

It is a multi-center , open-label, single arm study conducted in 2 parts. Dose-escalation part: Subjects will receive oral Clifutinib Besylate once on C0D1.After 3 days,they will receive Clifutinib Besylate once daily repeatedly until disease progression or unacceptable toxicity occurs, each cycle is defined as 28 days.

Expansion part:Expansion cohort might be set to further investigate the safety and efficacy of Clifutinib Besylate at or lower MTD dose recommended by dose-escalation part.
