Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Part 1a: Dose escalation
INCA035784 will be administered at a protocol defined starting regimen in 28-day cycles as monotherapy to identify the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE[s]). Participants with myeloproliferative neoplasm (MPN) will enroll in this group.
  • Drug: INCA035784
    INCA035784 will be administered at the assigned dose in the dose escalation part and at the protocol defined dose in the dose expansion part.
Experimental
Part 1b: Dose expansion
INCA035784 will be administered as monotherapy at the RDE(s) identified during Part 1a. Participants with myeloproliferative neoplasm (MPN) will enroll in this group.
  • Drug: INCA035784
    INCA035784 will be administered at the assigned dose in the dose escalation part and at the protocol defined dose in the dose expansion part.
