简要总结
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.
详细描述
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).

- Total survival time (OS)(30 days after last subject discontinues treatment (assessed up to approximately 24 months))
- CR mitigation duration (DoR-CR)(Time from the date at which the patient's objective status is first noted to be a CR to the earliest date progression is documented (assessed up to approximately 24 months)
- 12-lead ECG(From the start of the study treatment to the end of the study treatment(Within 4 weeks after the last administration))
