What was measured

Overall response rate (ORR) per Central Adjudication Committee is the percentage of participants with a best response of stringent complete response (sCR), complete response (CR), very good partial response (VGPR), or partial response (PR). sCR: * No detectable myeloma cells in the bone marrow. * Normal free light chain ratio. * Absence of clonal cells in the bone marrow. CR: * Negative immunofixation on the serum and urine. * Disappearance of any soft tissue plasmacytomas. * Less than 5% plasma cells in the bone marrow. VGPR: * Serum and urine M-protein detectable by immunofixation but not on electrophoresis, or * At least a 90% reduction in serum M-protein plus urine M-protein level less than 100 mg per 24 hours. PR: * At least a 50% reduction in serum M-protein. * Reduction in 24-hour urinary M-protein by at least 90% or to less than 200 mg per 24 hours. * For patients with non-secretory myeloma, a reduction of at least 50% in the size of soft tissue plasmacytomas is required

Analysis population: All treated participants in the Efficacy Evaluable population. Data not collected.

Groups in this outcome

Phase 1b - ACY-1215 Dose Level 1

Participants received 160 mg ACY-1215 and 4 mg pomalidomide daily on Days 1-21 of each 28-day cycle. Participants also received 40 mg (\<=75 years) or 20 mg (\>75 years) dexamethasone on Days 1, 8, 15, and 22 of each 28-day treatment cycle.

Phase 1b - ACY-1215 Dose Level 3

Participants received 160 mg ACY-1215 twice daily in combination with 4 mg pomalidomide once daily on Days 1-21 of each 28-day cycle. Participants also received 40 mg (\<=75 years) or 20 mg (\>75 years) dexamethasone on Days 1, 8, 15, and 22 of each 28-day treatment cycle.

Phase 2 - ACY-1215 Dose Level 1

Participants received 160 mg ACY-1215 and 4 mg pomalidomide daily on Days 1-21 of each 28-day cycle. Participants also received 40 mg (\<=75 years) or 20 mg (\>75 years) dexamethasone on Days 1, 8, 15, and 22 of each 28-day treatment cycle.

Phase 2 - ACY-1215 Dose Level 3

Participants received 160 mg ACY-1215 twice daily in combination with 4 mg pomalidomide once daily on Days 1-21 of each 28-day cycle. Participants also received 40 mg (\<=75 years) or 20 mg (\>75 years) dexamethasone on Days 1, 8, 15, and 22 of each 28-day treatment cycle.
