Brief Summary:
The purpose of this study is to compare the efficacy (rate of very good partial response [VGPR] or better as best response as defined by the International Myeloma Working Group [IMWG] criteria) of daratumumab subcutaneous (Dara-SC) in combination with carfilzomib and dexamethasone (Kd) with the efficacy of Kd in participants with relapsed refractory multiple myeloma who were previously exposed to daratumumab intravenous (Dara-IV) to evaluate daratumumab retreatment.

Condition or disease Intervention/treatment Phase
Multiple Myeloma Drug: Carfilzomib 20 mg/m^2 Drug: Carfilzomib 70 mg/m^2 Drug: Dexamethasone 40 mg Drug: Dara-SC 1800 mg Phase 2

Detailed Description:
For relapsed or refractory multiple myeloma, the treatment is determined on an individual basis. Common standard of care regimens use either a proteasome inhibitor (PI) or an immunomodulatory agent (IMiD) in combination with dexamethasone with or without a monoclonal antibody (mAb) such as daratumumab. After relapse from PIs or IMiDs, patients are often retreated with drugs that have same mechanism of action to which they have been sensitive. The disease becomes refractory and all effective treatment options are exhausted. Daratumumab is a human IgG1 mAb that binds with high affinity to unique epitope on cluster of differentiation 38 (CD38) and attacks tumor cells that overexpress CD38. Study is to determine the efficacy of Dara-SC in combination with carfilzomib and dexamethasone (DKd) in adult participants with relapsed refractory MM who had 1 or 2 prior line(s) of treatment including a line containing Dara-IV to evaluate daratumumab retreatment. The MM treatment is determined on an individual basis where patient's age, prior therapy, bone marrow function, co-morbidities, patient preference and time to relapse are considered. Common standard of care regimens use either PI or an IMiD in combination with dexamethasone with or without a mAb. It is a targeted immunotherapy that attacks tumor cells that overexpress CD38, a transmembrane glycoprotein, in a variety of hematological malignancies including multiple myeloma. The study will be conducted in 3 phases: Screening (28 days), Treatment, and Follow-Up. Assessments like chest X-ray, spirometry test, electrocardiogram (ECG), will be performed during Screening phase. During the Treatment Phase, participants will be randomized to receive Kd or DKd. Efficacy assessments like bone marrow examination will be performed. Follow-up will continue until the end of study.

Primary Outcome Measures :
  1. Percentage of Participants Achieving Very Good Partial Response (VGPR) or Better Response [ Time Frame: Approximately 2 years ]
    Percentage of participants achieving VGPR or better response according IMWG criteria for VGPR will be reported. IMWG criteria for VGPR: Serum and urine M-component detectable by immunofixation but not on electrophoresis, or greater than or equal to (>=) 90 percent (%) reduction in serum M-protein plus urine M-protein less than (<) 100 milligram (mg)/24 hours.


Secondary Outcome Measures :
  1. Overall Response Rate (ORR) [ Time Frame: Approximately 2 years ]
    ORR is defined as percentage of participants who achieve partial response (PR) or better (including VGPR, CR, sCR) responses prior to subsequent anti-myeloma therapy. IMWG criteria for PR: >=50% reduction of serum M-protein and reduction in 24-hour urinary M-protein by >=90% or to <200 mg/24 hours; If the serum and urine M-protein are not measurable, a decrease of >=50% in the difference between involved and uninvolved free light chain (FLC) levels is required in place of the M-protein criteria; If serum and urine M-protein are not measurable, and serum free light assay is also not measurable, >=50% reduction in bone marrow plasma cells (PCs) is required in place of M-protein, provided baseline bone marrow plasma cell percentage was >=30%; additionally, if present at baseline, a >=50% reduction in the size of soft tissue PCs is also required.

  2. Percentage of Participants Achieving Complete Response (CR) or Stringent Complete Response (sCR) [ Time Frame: Approximately 2 years ]
    Complete response is based on serum M-Protein assessments. IMWG criteria for CR: Negative immunofixation on the serum and urine, and Disappearance of any soft tissue plasmacytomas (PCs), and <5% PCs in bone marrow. IMWG criteria for sCR defined as, CR plus normal free light chain (FLC) ratio, and Absence of clonal PCs by immunohistochemistry, immunofluorescencea or 2- to 4- color flow cytometry.

  3. Progression Free Survival (PFS) [ Time Frame: Up to approximately 3.3 years ]
    PFS is time from date of randomization to date of documented progressive disease (PD) on first line treatment given for multiple myeloma (MM) or death, whichever comes first. IMWG criteria for PD: >=25% from lowest response level in serum M-component (the absolute increase must be >=0.5 gram per deciliter [g/dL]) and/or in urine M-component (the absolute increase must be >=200 mg/24 hour); only in participants without measurable serum and urine M-protein levels: increase of >=25% in the difference between involved and uninvolved free light chain levels and the absolute increase must be >10 mg/dL. BMPC%: the absolute % must be >=10%; definite increase in size of existing bone lesions or soft tissue plasmacytomas; definite development of new bone lesions or soft tissue plasmacytomas; development of hypercalcemia (corrected serum calcium >11.5 milligrams per deciliter (mg/dL) or 2.65 millimoles per liter [mmol/L]) that can be attributed solely to PC proliferative disorder.

  4. Overall Survival (OS) [ Time Frame: Up to approximately 3.3 years ]
    OS is defined as the time from the date of first dose of study drug to date of death due to any cause. If the participant is alive or the vital status is unknown, the participant will be censored at the date the participant will be last known to be alive.

  5. Percentage of Participants With Negative Minimal Residual Disease (MRD) [ Time Frame: Approximately 2 years ]
    Percentage of participants who have achieved MRD negative status will be assessed.

  6. Time to Next Treatment [ Time Frame: Up to approximately 3.3 years ]
    Time to next treatment is defined as the time from randomization to the start of the next-line treatment.

  7. Serum Concentrations of Daratumumab [ Time Frame: Arm A: Cycle 1 (each cycle of 28 days) Day 1 (Cycle 1 Day 1), Cycle 3 Day 1; Arm B: Cycle 1 Day1, Cycle 3 Day 1, Cycle 7 Day 1 and Follow Up (post treatment Week 8) ]
    Serum concentrations of daratumumab will be assessed.

  8. Number of Participants with Anti-Daratumumab Antibodies [ Time Frame: Arm A: Cycle 1 (each cycle of 28 days) Day 1 (Cycle 1 Day 1), Cycle 3 Day 1; Arm B: Cycle 1 Day1, Cycle 3 Day 1, Cycle 7 Day 1 and Follow Up (post treatment Week 8) ]
    Number of participants who test positive for anti-daratumumab antibodies will be reported.

  9. Number of Participants with Anti-recombinant Human Hyaluronidase (rHuPH20) Antibodies [ Time Frame: Arm A: Cycle 1 (each cycle of 28 days) Day 1 (Cycle 1 Day 1), Cycle 3 Day 1; Arm B: Cycle 1 Day1, Cycle 3 Day 1, Cycle 7 Day 1 and Follow Up (post treatment Week 8) ]
