Summary

This is a Phase 2, open-label, multicenter study to safety \& tolerability, antitumor activity, and pharmacokinetics of FCN-338 in Combination with szacitidine (AZA) or chemotherapy(erythromycin, cytarabine(Ara-C)) in Patients with myeloid neoplasms

Detailed description

Primary Objectives:1.To assess the safety and tolerability of FCN-338 in combination with AZA or chemotherapy in patients with myeloid neoplasms. 2. To explore the antitumor activity of FCN-338 combination therapy in patients with myeloid neoplasms. Secondary Objectives: 1. To assess the pharmacokinetic profile of the FCN-338 combination therapy in patients with myeloid neoplasms.2. To assess the transfusion independence rate in patients with myeloid neoplasms. There were 2 cohorts based on different combination therapies and different indications. Cohort A is FCN-338 combined with AZA (75mg/m², SC, QD, D1-7) for the treatment in relapsed/refractory (R/R) acute myeloid leukemia (AML) patients. Cohort B is FCN-338 combined with intensive chemotherapy for first line (1L) fit AML patients. During the induction phase, patients will be treated with erythromycin (60 mg/m², IV, QD , D1-3) and Ara-C (100 mg/m², IV, QD, D1-7). Patients achieving partial remission (PR) will repeat induction phase once, and patients who do not reach PR after first cycle of induction phase and those who do not achieve complete remission (CR)/Complete remission with incomplete hematological recovery (CRi)/morphologic leukemia-free state (MLFS) after two cycles of induction phase will receive other new antitumor treatments. Patients who achieve CR/CRi/MLFS will undergo consolidation phase with medium- to high-dose Ara-C (1 to 3 g/m²/12h, 6 doses) for 3 to 4 cycles, with the exact dose and number of cycles determined by investigator. Patients with intermediate- to high-risk according to the 2017 European Leukemia Net (ELN) stratification will undergo a total of 24 cycles of maintenance phase after completion of consolidation phase. Maintenance phase will consist of 24 cycles, FCN-338 in combination with AZA (50 mg/m², d1-5) for the first 12 cycles and FCN-338 alone for the rest 12 cycles. FCN-338 will be administered once daily (QD), D1-14 per cycle during induction phase, consolidation phase and maintenance phase.
