Description of intervention(s) / exposure
Treatment: Drugs - INCA033989
Treatment: Drugs - Ruxolitinib

Experimental: Part 1a Dose Escalation Cohort Disease Group A - with MF - INCA033989 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 myelofibrosis (MF) will enroll in this group.

Experimental: Part 1a Dose Escalation Cohort Disease Group A - with ET - INCA033989 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 with essential thrombocythemia (ET) will enroll in this group.

Experimental: Part 1a: Dose Escalation Cohort Disease Group B - with TGB-MF SubOpt R - INCA033989 will be administered at a protocol defined starting regimen in 28- day cycles and will allow for the evaluation of INCA033989 in combination with ruxolitinib to identify the maximum tolerated dose (MTD) and/or recommended dose for expansion (RDE[s]). Participants with myelofibrosis (MF) exhibiting suboptimal response (SubOpt R) will enroll in this group.

Experimental: Part 1b: Dose Expansion - with MF - INCA033989 will be administered as monotherapy at the RDE(s) identified during Part 1a. Participants with treatment group A (TGA) myelofibrosis MF will enroll in this group.

Experimental: Part 1b: Dose Expansion - with TGB-MF SubOpt R - INCA033989 will be administered as an add-on therapy in combination with ruxolitinibat at the RDE(s) identified during Part 1a. Participants with treatment Group B (TGB) MF SubOpt R will enroll in this group.

Experimental: Part 1b: Dose Expansion - with ET - INCA033989 will be administered as monotherapy at the RDE(s) identified during Part 1a. Participants with treatment group A (TGA) essential thrombocythemia (ET) will enroll in this group.

Experimental: Part 1c: Dose Expansion - INCA033989 will be administered at the dose level found to exhibit an overall positive benefit/risk as monotherapy or as combination therapy with Ruxolitinib. Participants with myelofibrosis (MF) will enroll in this group. The participants enrolled in the monotherapy arm will be offered the option to crossover to combination therapy with ruxolitinib if a suboptimal response to monotherapy is observed after 12 weeks.


Treatment: Drugs: INCA033989
INCA033989 will be administered at protocol defined dose.

Treatment: Drugs: Ruxolitinib
Rux will be administered according to Prescribing Information/SmPC.
