Multiple myeloma (MM) is a plasma cell disease characterized by the growth of clonal plasma
cells in the bone marrow. The purpose of this study is to assess the safety and toxicity of
ABBV-453 in adult participants with relapsed/refractory (R/R) MM. Adverse events and change
in disease activity will be assessed.

ABBV-453 is an investigational drug being developed for the treatment of R/R MM. Part 1 will
be a monotherapy dose escalation phase to determine the best dose of ABBV-453. In Part 2,
participants are placed in 1 of 3 groups called treatment arms. Each group receives a
different treatment. Approximately 28 to 48 adult participants in Part 1 and 150 to 312 adult
participants in Part 2 with R/R MM will be enrolled in the study in approximately 70 sites
worldwide.

In Part 1 and the Japan Cohort, Participants will receive oral ABBV-453 tablets once daily
(QD) in 28-day cycles. In Part 2, Arm 1, participants will receive continuous doses of oral
ABBV-453 tablets QD in combination with oral dexamethasone tablets once weekly in 28-day
cycles. In Part 2, Arm 2, participants will receive continuous doses of oral ABBV-453 tablets
QD in combination with subcutaneous injections of daratumumab every 1 to 4 weeks and oral
dexamethasone tablets once weekly in, 28-day cycles. In Part 2, Arm 3, participants will
receive continuous doses of oral ABBV-453 tablets QD in combination with subcutaneous
injections of daratumumab every 1 to 4 weeks, oral lenalidomide capsules QD on Days 1-21, and
oral dexamethasone tablets once weekly, in 28-day cycles.

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 an approved
institution (hospital or clinic). The effect of the treatment will be frequently checked by
medical assessments, blood tests, and side effects.

Study CDFV890G12101 is an open-label, phase 1b, multicenter study with a randomized two-dose
optimization part, and a dose expansion part consisting of two groups evaluating DFV890 in
patients with myeloid diseases. The purpose of this study is to assess the safety,
tolerability, pharmacokinetics, pharmacodynamics, efficacy and recommended dose for single
agent DFV890 in patients with lower risk (LR: very low, low or intermediate risk)
myelodysplastic syndromes (LR MDS) and lower risk chronic myelomonocytic leukemia (LR CMML).
