Inclusion Criteria

• Eastern Cooperative Oncology Group Performance Status of 0 to 2

For Parts A & B:

  • Relapsed or refractory (R/R) acute myeloid leukemia (AML) as defined by the 2016 WHO Classification
  • R/R myelodysplastic syndromes (MDS) as defined by the 2016 WHO Classification with intermediate, high or very high risk by Revised International Prognostic Scoring System (IPSS-R)

For Part C:

• Treatment-naïve (TN) (ie, previously untreated) MDS as defined by the 2016 WHO Classification with intermediate, high or very high risk by IPSS-R

For Part D:

• TN AML as defined by the 2016 WHO Classification, including secondary AML and therapy-related AML in participants who are ineligible (IE) for intensive chemotherapy (IC) and allogeneic hematopoietic stem cell transplant (HSCT)

Exclusion Criteria
  • Acute promyelocytic leukemia
  • Immediately life-threatening, severe complications of leukemia such as disseminated/uncontrolled infection, uncontrolled bleeding, and/or uncontrolled disseminated intravascular coagulation
  • Participants who have received prior treatment with a CD47 or SIRPα targeting agent
  • Participant is on chronic systemic immunosuppressive therapy or corticosteroids
  • Prior systemic cancer-directed treatments or investigational modalities ≤ 5 half-lives or 4 weeks prior to starting study treatment, whichever is shorter (relapsed or refractory participants only).
  • Any condition including, active or uncontrolled infection, or the presence of laboratory abnormalities, which places the participant at unacceptable risk if he/she were to participate in the study
  • Pregnant or nursing participants.
