A Clinical Trial to Evaluate Clifutinib in Patients With Relapsed or Refractory Acute Myeloid Leukemia(AML)

Phase 1
Conditions
Acute Myeloid Leukemia
Interventions
Registration Number
NCT04827069
Lead Sponsor
Sunshine Lake Pharma Co., Ltd.
Brief 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.

Detailed 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.
