Study Details
Study Description
Brief Summary
The purpose of this study is to evaluate the tolerability and safety of subcutaneous (SC) delivery of co-formulated daratumumab and rHuPH20 preparation (DARA SC) in Japanese participants with relapsed or refractory multiple myeloma (MM).

| Experimental: DARA SC Participants will receive DARA SC (daratumumab 1800 milligram [mg] with Recombinant Human Hyaluronidase [rHuPH20] 30,000 units [U] that is 2000 U/milliliter [U/mL]) subcutaneous (SC) injection once weekly for the first 8 weeks in Cycles 1 and 2 (Days 1, 8, 15, and 22 of each week), every 2 weeks in Cycles 3 to 6 (Days 1 and 15) for the following 16 weeks and then every 4 weeks (from Cycle 7 [Day 1]) in subsequent cycles until disease progression, unacceptable toxicity, or any other reason for discontinuation. Each cycle is 28 days in duration. |
Drug: DARA SC
Participants will receive 1800 mg daratumumab with 30,000 U (2000 U/mL) rHuPH20 SC injection once weekly for the first 8 weeks in Cycles 1 and 2 and every 2 weeks in Cycles 3 to 6 for 16 weeks and then every 4 weeks in subsequent cycles until disease progression, unacceptable toxicity, or any other reason for discontinuation.

Outcome Measures
Primary Outcome Measures
- Number of Participants With Adverse Events Including Dose Limiting Toxicity [Up to 30 days after last study drug dose (approximately up to 1 year)]
An adverse event (AE) is any untoward medical occurrence in participant who received study drug without regard to possibility of causal relationship.
Secondary Outcome Measures
- Maximum Observed Concentration (Cmax) of Daratumumab [Up to 8 weeks after the last dose of study drug (approximately up to 1 year)]
Maximum observed concentration of daratumumab will be measured.
- Maximum Serum Trough Concentration (Ctrough) of Daratumumab [At Cycle 3 Day 1 predose concentration]
Ctrough is the concentration of daratumumab prior to the next drug administration.
- Serum Concentration of Daratumumab and Recombinant Human Hyaluronidase (rHuPH20) (Plasma) Antibodies [Up to 8 weeks after the last dose of study drug (approximately up to 1 year)]
Serum levels of antibodies to daratumumab and rHuPH20 will be analyzed for evaluation of potential immunogenicity.
- Overall Response Rate [Approximately up to 1 year]
Overall Response is partial response (PR)/better as per International Myeloma Working Group (IMWG) criteria. PR: >=50% reduction of serum M-protein, >=90% reduction in 24 hour urinary M-protein or to <200 mg/24 hours; if serum and urine M-protein are not measurable, >=50% decrease in difference between involved and uninvolved free light chains (FLC) levels; if serum and urine M-protein and serum free light assay is not measurable, >=50% reduction in bone marrow plasma cell (PC), with baseline bone marrow PC percentage >=30%; if present at baseline, >=50% reduction in size of soft tissue plasmacytomas; Very good partial response: serum and urine M-component detectable by immunofixation or >=90.0% reduction in serum M-protein and urine M-protein <100mg/24 hours; Complete response (CR):negative immunofixation on serum and urine, disappearance of soft tissue plasmacytomas and <5.0% PCs in bone marrow; Stringent complete response (sCR): CR plus normal FLC ratio and absence of clonal PCs.
- Duration of Response (DOR) [First documentation of confirmed PR or better to the date of first documented progressive disease (PD), or date of death due to PD, whichever occurs first (approximately up to 1 year)]
DOR is date of first documentation of confirmed PR or better to date of first documented PD (as per IMWG criteria), or date of death due to PD, whichever occurs first. PD: 25% increase from lowest response value in 1 of following: serum M-component, urine M-component (absolute increase must be >= 0.5 gram per deciliter [g/dL], >= 200 mg/24 hours respectively), Only in participants without measurable serum and urine M-protein levels: difference between involved and uninvolved FLC levels (absolute increase must be >10 milligram per deciliter (mg/dL), only in participants without measurable serum and urine M-protein levels and without measurable disease by FLC levels, bone marrow PC% (absolute percentage must be >=10%), definite development of new bone lesions or soft tissue plasmacytomas or increase in size of bone lesions or tissue plasmacytomas and development of hypercalcemia (serum calcium >11.5 mg/dL) attributed solely to PC proliferative disorder.
- Time to Response [Approximately up to 1 year]
Time to response is defined as the time between Cycle 1 Day 1 and the first efficacy evaluation date that the participant has met all criteria for PR or better (as per IMWG criteria). PR: >=50% reduction of serum M-protein, >=90% reduction in 24 hour urinary M-protein or to <200 mg/24 hours; if serum and urine M-protein are not measurable, >=50% decrease in difference between involved and uninvolved FLC levels; if serum and urine M-protein and serum free light assay is not measurable, >=50% reduction in bone marrow PC, with baseline bone marrow PC percentage >=30%; if present at baseline, >=50% reduction in size of soft tissue plasmacytomas; Very good partial response: serum and urine M-component detectable by immunofixation or >=90.0% reduction in serum M-protein and urine M-protein <100mg/24 hours; CR: negative immunofixation on serum and urine, disappearance of soft tissue plasmacytomas and <5.0% PCs in bone marrow; sCR: CR plus normal FLC ratio and absence of clonal PCs.
