E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to evaluate the long-term safety of siltuximab in subjects with MCD. |
|
E.2.2 | Secondary objectives of the trial |
- To determine the proportion of previously responding subjects who maintain disease control
- To determine the proportion of siltuximab-naive subjects who experience disease control
- To describe the duration of disease control and survival
- To assess reliability of a multicentric Castleman’s disease symptom scale (MCDSS)
- To evaluate IL-6 levels
- To assess formation of antibodies to siltuximab (immunogenicity) after long-term treatment in the MCD population |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
- Have multicentric Castleman's disease
- Have previously been enrolled in Study C0328T03 or CNTO328MCD2001 (either treatment arm)
- Have had their last administration of study treatment (siltuximab or placebo) less than 6 weeks (window of plus 2 weeks) prior to first dose
- Patients must not have had disease progression while receiving siltuximab. For those patients originally assigned to placebo in the CNTO328MCD2001 study, patients who have received less than 4 months of siltuximab following crossover will also be eligible
- Have adequate clinical laboratory parameters within 2 weeks prior to the first dose of siltuximab for this study. |
|
E.4 | Principal exclusion criteria |
- Unmanageable toxicity, an adverse event, progression of disease, or withdrawal of consent as reason for discontinuing treatment from previous sponsor-initiated siltuximab study
- Vaccination with live, attenuated vaccines within 4 weeks of first dose of this study
- Known unmanageable allergies, hypersensitivity, or intolerance to monoclonal antibodies or to murine, chimeric, or human proteins or their excipients |
