Conditions

Acute Myeloid Leukemia (AML), Myelodysplastic Syndrome (MDS)

Brief summary

Incidence of CRS and non-CRS DLTs during the first cycle of treatment (phase 1 only), Type, incidence and severity of AEs according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v5.0, Changes in laboratory safety parameters and vital signs, Overall response rate (ORR) based on best overall response of complete remission, complete remission with partial hematological recovery (CRh); complete remission with incomplete hematological recovery (CRi), morphologic leukemia-free state (MLFS) and partial remission (PR) according to the European LeukemiaNet (ELN) response criteria 2022 (phase 2a only)

Detailed description

Determination of PK parameters including (but not limited to) Cmax, time at Cmax (Tmax), minimal serum concentration (Cmin), area under the concentration-time curve (AUC), total CL, volume of distribution (Vd) and t1/2, Different levels of CR, CRh, Cri, MLFS and PR according to the ELN response criteria 2022, separately and pooled, Event free survival (EFS) based on ELN response criteria 2022, Duration of response (DoR) based on ELN response criteria 2022, Overall survival (OS) (phase 2a only), Number of patients proceeding to a stem cell transplantation (phase 2a only), Transfusion-Independence (TI)
