Part 1a Dose Escalation Cohort Disease Group A - with MFINCA033989INCA033989 will be administered at a protocol defined starting regimen in 28-day cycles to identify the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE\[s\]). Participants with myelofibrosis (MF) will enroll in this group.
Part 1a Dose Escalation Cohort Disease Group A - with ETINCA033989INCA033989 will be administered at a protocol defined starting regimen in 28-day cycles to identify the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE\[s\]). Participants with essential thrombocythemia (ET) will enroll in this group.
Part 1b: Dose Expansion - with ETINCA033989INCA033989 will be administered at the RDE(s) identified during Part 1a. Participants with treatment group A (TGA) essential thrombocythemia (ET) will enroll in this group.
Part 1b: Dose Expansion - with MFINCA033989INCA033989 will be administered at the RDE(s) identified during Part 1a. Participants with treatment group A (TGA) myelofibrosis MF will enroll in this group.
