Brief Summary:
The purpose of this study is to evaluate the safety and antitumor activity of INCB001158 in combination with daratumumab SC, compared with daratumumab SC alone, in participants with relapsed or refractory multiple myeloma who have received at least 3 but not more than 5 prior lines of multiple myeloma therapy.

Condition or disease Intervention/treatment Phase
Relapsed or Refractory Multiple Myeloma Drug: INCB001158 Biological: Daratumumab SC Phase 1 Phase 2

Layout table for study information
Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 98 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Intervention Model Description: An initial equal randomization of participants between INCB001158 in combination with daratumumab SC (Treatment Group A), daratumumab SC monotherapy (Treatment Group B), and INCB001158 monotherapy (Treatment Group C) will be conducted. Participants in the INCB001158 monotherapy group will be treated for at least 2 cycles provided that the participants are not progressing and will then cross over to INCB001158 + daratumumab SC at the time of disease progression. After the equal randomization period, a response adaptive randomization design will be used to compare the objective response rate of Treatment Groups A and B with adjustments to the randomization rate based on the observed objective response rate.

Arm Intervention/treatment
Experimental: INCB001158 + daratumumab SC Drug: INCB001158
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. Phase 2: INCB001158 administered orally at the recommended dose from Phase 1.

Biological: 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.

Active Comparator: Daratumumab monotherapy Biological: 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.

Experimental: INCB001158 monotherapy cross over INCB001158 + daratumumab SC
INCB001158 monotherapy, then cross over to INCB001158 + daratumumab SC
Drug: INCB001158
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.

Biological: 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.




Primary Outcome Measures :
  1. Phase 1: Number of treatment-emergent adverse events with INCB001158 in combination with daratumumab [ Time Frame: Up to approximately 2 years ]
    Defined as any adverse event either reported for the first time or worsening of a pre-existing event after first dose of study drug.

  2. Phase 2: Objective response rate with INCB001158 in combination with daratumumab compared to daratumumab monotherapy [ Time Frame: Up to approximately 2 years ]
    Defined as the proportion of participants with a documented response of partial response (PR) or better, per International Myeloma Working Group (IMWG) criteria.


Secondary Outcome Measures :
  1. Time to response [ Time Frame: Up to approximately 2 years ]
    Defined as the time from the first dose of study drug to the first documented response PR or better, as per IMWG criteria.

  2. Duration of response [ Time Frame: Up to approximately 2 years ]
    Defined as time from first documented response PR or better, as per IMWG criteria, until date of disease progression or death, whichever occurs first.

  3. Progression-free survival [ Time Frame: Up to approximately 3 years ]
    Defined as the duration from the date of first dose of study drug until either progressive disease (PD), as per IMWG criteria, or death, whichever occurs first.

  4. Minimal residual disease [ Time Frame: Up to approximately 2 years ]
    Defined as the percentage of MRD-negative participants.

  5. Overall survival [ Time Frame: Up to approximately 3 years ]
    Defined as the time from the first dose of study drug to the first documented response PR or better, as per IMWG criteria.
