Siltuximab 11 mg/kg, intravenous infusion, given as a 1-hour infusion every 3 weeks.
Type=exact number, unit=mg/kg, number=11, form=intravenous solution, route=intravenous. Siltuximab given as a 1-hour infusion every 3 weeks.
- Number of Participants With Adverse Events (AEs) [ Time Frame: 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 Previously Responding Participants Who Maintained Disease Control [ Time Frame: Up to 6 years ]Percentage of participants maintaining disease control (defined as stable or better response) was defined as the percentage of previously responding participants who had not progressed during the long-term safety extension based on investigator assessment. A worsening in any of the measures will be considered as a progression of the disease.
- Percentage of Siltuximab-naive Participants Who Experienced Disease Control [ Time Frame: Up to 6 years ]Percentage of participants experiencing disease control was defined as the percentage of siltuximab-naïve participants who had stable or better response during the long-term safety extension based on investigator's judgment. Disease control was defined as stable or better response assessed by the investigators.
- Duration of Disease Control [ Time Frame: Up to 6 years ]Duration of disease control (DODC) was defined as the time from the first siltuximab administration in this study to disease progression as assessed by the investigator. Disease control was defined as stable or better response assessed by the investigators. Kaplan-Meier method was used to estimate the duration of disease control.
- Overall Survival [ Time Frame: Up to 6 years ]Overall survival was defined as the time between the first study siltuximab administration and death due to any cause. Kaplan-Meier method was used to estimate the overall survival.
- Number of Participants Positive for Antibodies to Siltuximab [ Time Frame: Up to 6 years ]Serum samples were screened for antibodies binding to siltuximab and number of participants positive for antibodies to siltuximab was reported.
