Phase 1: INCB001158 administered orally twice daily at the protocol-defined starting dose, with dose escalation/de-escalation based on protocol-defined toxicity criteria to determine the maximum tolerated dose. INCB001158 is administered in combination with daratumumab SC. Phase 2: INCB001158 administered orally at the recommended dose from Phase 1 either as a monotherapy or in combination with daratumumab SC.
Daratumumab 1800 mg co-formulated with rHuPH20 (2000 U/mL) and administered subcutaneously once weekly for Cycles 1 and 2, once every 2 weeks for Cycles 3 to 6, and then once every 4 weeks. Daratumumab will be administered either as monotherapy or in combination with INCB001158.
Phase 1: Number of Participants With Any Treatment-emergent Adverse Event (TEAE)
A TEAE was defined as an adverse event (AE) that was reported for the first time or the worsening of a pre-existing event after the first dose of study treatment.
Time frame: up to 454 days
Phase 2: Overall Response Rate (ORR): Number of Participants With a Documented Response of Complete Response (CR), Very Good Partial Response (VGPR), or PR, as Per International Myeloma Working Group (IMWG) Criteria
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.
Time frame: up to Day 386
Phase 1: ORR: Number of Participants With a Documented Response of CR, VGPR, or PR, as Per IMWG Criteria
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%.
