What was measured

Duration of response was calculated from the date of initial documentation of a response (PR or better) to the date of first documented evidence of progressive disease, as defined in IMWG criteria. Disease progression (IMWG criteria): increase of 25 percent (%) from lowest response level in Serum M-component (the absolute increase must be \>=0.5 g/dL) and/or; urine M-component (the absolute increase must be \>=200 mg/24 hours) and/or; only in participants without measurable serum and urine M-protein levels: the difference between involved and uninvolved free light chain levels (absolute increase must be \>10 milligram per deciliter (mg/dL); Development of hypercalcemia (corrected serum calcium \>11.5 mg/dL or 2.65 millimole per liter \[mmol/L\]) that can be attributed solely to the plasma cell proliferative disorder.

Analysis population: Responders in all treated analysis set. Only those participants with confirmed PR and those who experienced progressive disease were analyzed.

Groups in this outcome

Daratumumab 8 mg/kg

Daratumumab 8 milligram per kilogram (mg/kg) every 4 weeks (Q4W) until disease progression or unacceptable toxicity.

Daratumumab 16 mg/kg

Daratumumab 16 mg/kg weekly for 8 weeks; then every 2 weeks (Q2W) for 16 weeks; then Q4W until disease progression or unacceptable toxicity.
