What was measured

CR: negative immunofixation on serum/urine, disappearance of soft tissue plasmacytomas, \<5% bone marrow plasma cells (PCs). VGPR: serum/urine M-component detectable by immunofixation but not on electrophoresis, or ≥90% reduction in serum M-protein (SMP) plus urine M-protein (UMP) \<100 milligrams (mg)/24 hours. PR: ≥50% reduction of SMP and reduction in 24-hour UMP by ≥90% or to \<200 mg/24 hours. SMP and UMP not measurable: decrease of ≥50% in the difference between involved and uninvolved FLC levels is required in place of the M-protein criteria. SMP and UMP not measurable, and serum free light assay is not measurable: ≥50% reduction in bone marrow PCs is required in place of M-protein, if Baseline bone marrow PC percentage was ≥30%. If present at Baseline, a ≥50% reduction in the size of soft tissue plasmacytomas is required.

Analysis population: No participants had a response of PR or better; thus, analysis was not conducted.

Groups in this outcome

Phase 1: INCB001158 75 mg BID + Daratumumab

In Phase 1, participants received oral INCB001158 75 milligrams (mg) twice daily (BID) in 28-day cycles starting at Cycle 1, and 1800 mg subcutaneous daratumumab, administered once weekly for Cycles 1 and 2, once every 2 weeks for Cycles 3 to 6, and once every 4 weeks thereafter. Treatment continued until disease progression, unacceptable toxicity, or discontinuation from study treatment for any other reason.

Phase 1: INCB001158 100 mg BID + Daratumumab

In Phase 1, participants received oral INCB001158 100 mg BID in 28-day cycles starting at Cycle 1, and 1800 mg subcutaneous daratumumab, administered once weekly for Cycles 1 and 2, once every 2 weeks for Cycles 3 to 6, and once every 4 weeks thereafter. Treatment continued until disease progression, unacceptable toxicity, or discontinuation from study treatment for any other reason.
