Arm Groups
| Arm | Description | Assigned 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. |
|
|
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. |
