What was measured

One-year PFS rate is defined as the percentage (%) of participants surviving 1 year after randomization without progression to multiple myeloma or death estimated by the Kaplan-Meier method and based on the International Myeloma Working Group (IMWG) calcium, renal, anemia, and bone lesions (CRAB) criteria. Progressive disease (PD) is defined as presence of an M- component in serum plus clonal plasma cells in the bone marrow plus 1 or more of the following: Calcium elevation (greater than \[\>\] 11.5 milligram per deciliter \[mg/dL\] \[\> 2.88 millimoles per liter {mmol/L}\]); Renal insufficiency (creatinine \> 2 mg/dL \[177 micromoles per liter or more\]; Anemia (hemoglobin less than \[\<\] 10 gram per deciliter \[g/dL\] or 2 g/dL lower than lower limit of normal \[LLN\] \[hemoglobin \< 6.5 mmol/L or 1.25 mmol/L lower than LLN\]); Bone disease (lytic lesions or osteopenia).

Analysis population: Intent-to-treat (ITT) population included participants who were randomly assigned to siltuximab or placebo treatment group based on an integrated voice response system (IVRS).

Groups in this outcome

Siltuximab

Participants received 15 milligram per kilogram (mg/kg) of siltuximab as a 1-hour intravenous (IV) infusion every 4 weeks until disease progression, unacceptable toxicity, withdrawal of consent, or the end of the study (up to 4 years after randomization of the last participant).

Placebo

Participants received placebo as a 1-hour IV infusion every 4 weeks until disease progression, unacceptable toxicity, withdrawal of consent, or the end of the study (up to 4 years after randomization of the last participant).

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
