* Prior HSCT with relapse beyond 3 months or prior CAR-T therapy in B-ALL with relapse beyond 2 months may be included only if off immunosuppression for a minimum of 4 weeks and no evidence of GVHD.
* Receiving at the time of first investigational medicinal product (IMP) administration corticosteroid as a concomitant medication with corticosteroid dose more than 10 mg/day of oral prednisone or the equivalent.
* AML, BPDCN, or HR-MDS participants with prior treatment with cellular therapy, eg, chimeric antigen receptor T cell (CAR-T) or chimeric antigen receptor NK cell (CAR-NK). Prior CAR-T therapy is allowed for participants with B-ALL.
* Concurrent treatment with other investigational drugs.
* Pregnant and breast-feeding women.
* History of solid organ transplant, including corneal transplant.
* Average QTc (using the Fridericia correction calculation) greater than 470 millisecond (msec) at screening.
* Pediatric arm only: Participants with known inherited bone marrow failure syndromes (e.g., bloom syndrome, ataxia-telangiectasia, Fanconi anemia, Kostmann syndrome, Shwachman syndrome). Participants with Down syndrome with adequate organ function as per Investigator discretion are allowed to participate in the study.
* Adult arm Expansion/Optimization- Participants with MDS evolving from a pre-existing myeloproliferative neoplasm (MPN), MDS/MPN including chronic myelomonocytic leukemia (CMML), atypical chronic myeloid leukemia (aCML), unclassifiable MDS/MPN and therapy-related MDS (t-MDS).
* Confirmed diagnosis of acute promyelocytic leukemia (APL) or juvenile myelomonocytic leukemia (JMML) according to WHO 2022 classification.
