Study Endpoints
Primary Endpoints
Number of Participants With Adverse Events (AEs)
Up to 6 years

An adverse event (AE) is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

Percentage of Participants Who Achieved Durable Tumor and Symptomatic Response - by Independent Radiology Review
From Day 1 of Cycle 1 of treatment with study medication until treatment failure or discontinuation of treatment or withdrawal from study, or up to 48 weeks after last participant started study medication(approximately 3 years), whichever occurred earlier

Durable tumor and symptomatic response is complete response (CR) + partial response (PR). CR: complete disappearance of all measurable and evaluable disease (eg, pleural effusion) and resolution of baseline symptoms attributed to multicentric Castleman's disease, sustained for at least 18 weeks. PR: \>=50 percent decrease in sum of the product of the diameters of indicator lesion(s), with at least stable disease in all other evaluable disease in the absence of treatment failure sustained for at least 18 weeks. The statistical analysis shows difference in symptomatic response rate (siltuximab+best supportive care \[BSC\] minus Placebo+BSC).

SiltuximabEXPERIMENTALSiltuximab 11 mg/kg, intravenous infusion, given as a 1-hour infusion every 3 weeks.
Siltuximab+best supportive care (BSC)EXPERIMENTALSiltuximab 11 mg/kg will be administered as a 1-hour intravenous infusion every 3 weeks + BSC.
Placebo+BSCPLACEBO_COMPARATORPlacebo will be administered as a 1-hour intravenous infusion every 3 weeks + BSC. Participants who do not respond to placebo during the blinded treatment period will have option to crossover and receive siltuximab 11 mg/kg which will be administered by 1-hour intravenous infusion every 3 weeks + BSC during the unblinded treatment period.
