A Study of JNJ-89853413 for Relapsed or Refractory Acute Myeloid Leukemia or Myelodysplastic Neoplasms
The purpose of Part 1 (Dose Escalation) of the study is to assess the safety and
tolerability, and to identify the recommended Phase 2 dose[s] (RP2D[s]) in participants
with relapsed or refractory (R/R) acute myeloid leukemia (AML) (that is a type of blood
cancer that has come back after treatment/or has stopped responding to treatment) or R/R
higher-risk type of myelodysplastic neoplasms (MDS, type of blood cancer). The purpose of
Part 2 (Cohort Expansion) is to further assess the safety, tolerability and efficacy in
participants with R/R AML or higher-risk types of MDS.
