Myelofibrosis (MF) is a bone marrow illness that affects blood-forming tissues in the body. MF disturbs the body's normal production of blood cells, causing extensive scarring in the bone marrow. This leads to severe anemia, weakness, fatigue, and an enlarged spleen. The purpose of this study is to see how safe and tolerable ABBV-744 is, when given alone, and in combination with ruxolitinib or navitoclax, for adult participants with MF.
ABBV-744 is an investigational drug being developed for the treatment of MF. The study has 4 segments - A, B, C, and D. In Segment A, the safe dosing regimen of ABBV-744 is identified and then, given alone as monotherapy. In Segment B, C, and D, combination therapies of ABBV-744 with either ruxolitinib or navitoclax are given. Adult participants with a diagnosis of MF will be enrolled. Around 130 participants will be enrolled in 60 sites worldwide.
In Segment A, participants will receive different doses and schedules of oral ABBV-744 tablet to identify safe dosing regimen. Additional participants will be enrolled at the identified monotherapy dosign regimen. In Segment B, participants will receive oral ruxolitinib and ABBV-744 will be given as "add-on" therapy. In Segment C, participants will receive ABBV-744 and oral navitoclax. In Segment D, participants will receive ABBV-744 and ruxolitinib. Participants will receive treatment until disease progression or the participants are not able to tolerate the study drugs.
There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of treatment will be checked by medical assessments, blood and bone marrow tests, checking for side effects, and completing questionnaires.

- Percentage of Participants With Adverse Events [ Time Frame: Up to Approximately 1 year from start of study ]An adverse event (AE) is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with the treatment. The investigator assesses the relationship of each event to the use of study drug.

- Time To Cmax (Tmax) Of ABBV-744 [ Time Frame: Up To Week 12 ]The amount of time taken to reach Cmax.
- Area Under The Concentration Versus Time Curve (AUC) Of ABBV-744 [ Time Frame: Up To Week 12 ]AUC of ABBV-744 will be calculated.
- Half-Life (t1/2) Of ABBV-744 [ Time Frame: Up To Week 12 ]Half-life of ABBV-744 will be calculated.
- Accumulation Ratio Of ABBV-744 [ Time Frame: Up To Week 12 ]Pharmacokinetic parameters will include accumulation ratio of ABBV-744.
- Apparent Clearance (CL/F) Of ABBV-744 [ Time Frame: Up To Week 12 ]CL/F of ABBV-744 will be calculated.
- Apparent Volume Of Distribution (Vd/F) Of ABBV-744 [ Time Frame: Up To Week 12 ]Vd/F of ABBV-744 will be calculated.
- Percentage Of Participants With >= 50% Reduction In Total Symptom Score (TSS) [ Time Frame: Up to Week 24 ]TSS is assessed using the Myelofibrosis Symptom Assessment Form (MFSAF) v4.0. MFSAF v4.0 measures the burden of myelofibrosis-related symptoms. The symptoms are assessed on a 11-point numeric rating scale (NRS) anchored from 0 (absent) to 10 (worst imaginable).
- Objective Response Rate (ORR) [ Time Frame: Week 24 ]ORR is defined as the sum of rates of partial remission (PR) or better.
