What was measured

PFS is defined as the time between randomization and initial documented PD according to the CRAB - International Myeloma Working Group (IMWG) criteria or date of death, whichever occurs first. 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 (\> 11.5 mg/dL \[\> 2.88 mmol/L\]); Renal insufficiency (creatinine \> 2 mg/dL \[177 \[micro mol/L or more\]); Anemia (\<10 g/dL or 2 g/dL) lower than LLN) \[hemoglobin \< 6.5 mmol/L or 1.25 mmol/L lower than LLN\]); Bone disease (lytic lesions or osteopenia).

Analysis population: ITT population included participants who were randomly assigned to siltuximab or placebo treatment group based on an 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).
