Inclusion Criteria
  • Eastern Cooperative Oncology Group Performance Status of 0 to 2
  • Not eligible for stem cell/bone marrow transplant or have refused stem cell/bone marrow transplant or have relapsed after autologous or allogeneic stem cell/bone marrow transplant
  • Eligible for and agree to BM aspirate prior to treatment start
  • Measurable disease M component in serum (≥ 0.5 g/dL) and/or urine (≥ 0.2 g excreted in a 24 hour collection sample)
  • Must have received at least 3 prior lines of therapy including a proteasome inhibitor and an immunomodulatory agent or those who are double refractory to a PI and an immunomodulatory agent and have demonstrated disease progression (DP) on or within 60 days of completion of the last therapy; participants previously treated with an alkylating agent, in addition to an IMiD or proteasome inhibitor, are allowed to enroll in the trial
  • Participants must have adequate liver, kidney, and bone morrow function
  • Participants with a history of chronic heart failure must have cardiac ECHO indicating left ventricular ejection fraction (LVEF) ≥ 45% within 21 days prior to first dose of study drug
  • Participants in the combination therapy arms must be eligible to receive pomalidomide/dexamethasone, bortezomib/dexamethasone or lenalidomide/dexamethasone or other approved agents per current prescribing information for MM.
  • Participants who will receive combination therapy with Pomalidomide/Dexamethasone must have received at least two prior therapies including lenalidomide and a proteasome inhibitor and have demonstrated disease progression on or within 60 days of completion of the last therapy
Exclusion Criteria
  • Received anti-cancer therapy including chemotherapy, immunotherapy, radiation, biologic, any investigational therapy or herbal therapy within a period of 21 days prior to the first dose of ABBV-838, and have unresolved toxicities ≥ grade 2
  • Concurrent metastatic solid tumors
  • Non-Measurable M Protein (serum or urine) and measurable sFLC (< 100 mg/mL)
  • Major surgery within 21 days prior to the first dose of ABBV-838
  • Clinically significant uncontrolled condition(s) including but not limited to the following:

Grade ≥ 3 peripheral neuropathy or grade 2 peripheral neuropathy with pain Uncontrolled hypercalcemia Active uncontrolled infection Symptomatic congestive heart failure Unstable angina pectoris or cardiac arrhythmia Psychiatric illness/social situation that would limit compliance with the study

  • Major immunologic reaction to any IgG containing agent or auristatin based agent
  • Participants who are taking strong CYP3A4 inhibitors
  • Positive for HIV (Human Immunodeficiency Virus) or with active hepatitis B and/or C
  • Corneal pathology that would limit evaluation of loss in visual acuity associated with corneal deposits.
  • Prior exposure to pomalidomide for subjects enrolling in the pomalidomide/dexamethasone combination arm.

Primary Outcome Measures
NameTimeMethod
Maximum tolerated dose of ABBV-838Up to 2 years from first dose of study

The highest dose level at which less than 2 of 6 subjects or less than 33% of (if cohort is expanded beyond 6) subjects experience a dose limiting toxicity.

Maximum plasma concentration (Cmax) of ABBV-838Cycle 1 Day 1 (C1D1) and C3D1 pre- and post-dose; C1D4, C1D8, C1D15, C2D1, C2D15, C3D4, C3D8, C3D15, C4D1, and all subsequent ABBV-838 pre-dose dosing cycles

The maximum plasma concentration (Cmax: measured in ng/ml) is the highest concentration that a drug achieves in the blood after the first dose, but before administration of a second dose.

Secondary Outcome Measures
NameTimeMethod
Preliminary activity of ABBV-838 monotherapyAt screening, Cycle 1 Day 15 (C1D15), C3D15, C4D1, and for subjects who have been on ABBV-838 for ≥ 6 cycles, radiologic tumor assessments may be performed every 3 cycles per Investigator discretion up to approximately 3 years

Response evaluation will be based on International Myeloma Working Group (IMWG) Response Criteria.
