- Received at least 2 prior therapies including an Immunomodulatory Thalidomide Derivative Compounds (IMiD) and a proteasome inhibitor.
- Documented relapsed or progressive multiple myeloma on or after any regimen or is refractory to the most recent line of therapy.
- Received at least 2 prior therapies including an IMiD and a proteasome inhibitor.
- Documented relapsed or progressive multiple myeloma on or after any regimen or is refractory to the most recent line of therapy.

Exclusion Criteria:
- Received any anti-myeloma therapy (other than monoclonal antibodies), including chemotherapy, radiotherapy, biological, immunotherapy or an investigational therapy, including targeted small molecule agents within 5 half-lives (or 14 days if half-live unknown) prior to first dose of first dose of venetoclax, ABBV-838, and dexamethasone.

Arms of the Study
Arm 1
Arm 2
Experimental
Experimental
Arm A Venetoclax QD + ABBV-838 Q3W + Dexamethasone
Arm B Venetoclax QD + ABBV-838 Q1W or Q2W + Dexamethasone Q1W
ABBV-838 administered at cohort-defined doses every 3 weeks (Q3W; starting dose 4.0 mg/kg) in combination with venetoclax (400 mg or 800 mg once daily [QD]) and dexamethasone (40 mg once weekly [Q1W]); once the maximum-tolerated-dose (MTD) and recommended phase two dose (RPTD) are determined, ABBV-838 in combination with venetoclax and dexamethasone at RPTD will be administered in a dose expansion phase of the study.
Dose escalation portion will investigate either the ABBV-838 weekly (Q1W) or bi-weekly (Q2W) dosing interval in combination with venetoclax (400 or 800 mg QD) and dexamethasone (40 mg Q1W). The dose expansion portion will investigate either the ABBV-838 weekly (Q1W) or bi-weekly (Q2W) dosing interval in combination with venetoclax and dexamethasone at the RPTD combination defined from the Dose Escalation portion.
