Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Participants With Adverse Events

    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.

    Up to Approximately 1 year from start of study

Secondary Outcomes (16)

  • Percentage Of Participants Who Achieve Spleen Volume Reduction Of 35% Or Greater (SVR35)

    Up To Week 24

  • Maximum Observed Plasma Concentration (Cmax) of ABBV-744

    Up To Week 12

  • Time To Cmax (Tmax) Of ABBV-744

    Up To Week 12

  • Area Under The Concentration Versus Time Curve (AUC) Of ABBV-744

    Up To Week 12

  • Half-Life (t1/2) Of ABBV-744

    Up To Week 12

  • +11 more secondary outcomes

Study Arms (5)

Segment A: ABBV-744 Dose Identification and Optimization

EXPERIMENTAL

Participants who have been previously treated with Janus Kinase inhibitor(s) (JAKi) and stopped such therapy, will receive different dosing regimens and schedules of ABBV-744 to identify the safe dosing regimen and schedule.

Drug: ABBV-744

Segment A: ABBV-744 Monotherapy

EXPERIMENTAL

Participants will receive the identified safe dosing regimen of ABBV-744 as monotherapy.

Drug: ABBV-744

Segment B: Ruxolitinib + ABBV-744 "Add on" Therapy

EXPERIMENTAL

Participants whose disease (myelofibrosis) is inadequately controlled by ongoing ruxolitinib therapy will receive ruxolitinib and ABBV-744 as "add-on" therapy.

Drug: ABBV-744Drug: Ruxolitinib

Segment C: ABBV-744 + Navitoclax

EXPERIMENTAL

Participants who have previously been exposed to JAKi, and stopped such therapy, will receive ABBV-744 and navitoclax.

Drug: ABBV-744Drug: Navitoclax

Segment D: ABBV-744 + Ruxolitinib

EXPERIMENTAL

Participants who have never received JAKi will receive ABBV-744 and ruxolitinib.

Drug: ABBV-744Drug: Ruxolitinib
