A Clinical Study of SKLB1028 Capsule in the Treatment of Recurrence/Refractory AML Patients

Phase 2

• Conditions: Acute Myeloid Leukemia
• Interventions: Drug: SKLB1028 150mg bid; Drug: SKLB1028 200mg bid; Drug: SKLB1028 300mg qd

• Registration Number: NCT04015024
• Lead Sponsor: CSPC ZhongQi Pharmaceutical Technology Co., Ltd.

Brief Summary

Patients will receive oral SKLB1028 for 28 days as a course of treatment, and then to evaluate the side effects,tolerability and best dose for treating relapsed or refractory acute myeloid leukemia With FLT3 Mutations.

Detailed Description

It is an open,multicenter,queue extension study designed to characterize the efficacy and safety of different administration regimens of SKLB1028 capsules in patients with recurrent/refractory acute myeloid leukemia with FLT3 mutation. Divided into three dose groups,150mg BID,200mg BID,300mg QD. The main end point is total remission rate (ORR), total survival time (OS), progress-free survival time (PFS), remission duration, FLT3 suppression rate, competitive parameters, safety (incidence of adverse events).
