A Study of JNJ-90189892 for Relapsed or Refractory Acute Myeloid Leukemia or Myelodysplastic Neoplasms

Summary

The purpose of Part 1 (Dose Escalation) of the study is to assess the effective dose (recommended Phase 2 dose\[s\] \[RP2Ds\]) that can be safely administered, and dosing regimens of JNJ-90189892 in participants with relapsed or refractory (R/R) acute myeloid leukemia (AML) or R/R higher-risk type of myelodysplastic neoplasms (type of cancer of the blood and bone marrow, which does not respond to treatment or comes back after treatment). 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.
