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. |
El objetivo principal es evaluar la seguridad a largo plazo del siltuximab en pacientes con enfermedad de Castleman multicéntrica (ECM). |
|
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 |
-Determinar la proporción de pacientes previamente respondedores que mantienen el control de la enfermedad. -Determinar la proporción de pacientes sin exposición previa a siltuximab que presenten control de la enfermedad. -Describir la duración del control de la enfermedad y la supervivencia. -Evaluar la fiabilidad de una escala de síntomas de la enfermedad de Castleman multicéntrica (MCDSS). -Evaluar los niveles de IL-6. -Evaluar la formación de anticuerpos contra siltuximab (inmunogenicidad) después del tratamiento a largo plazo en la población con ECM. |

- 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. |

Para aquellos pacientes asignados originalmente a placebo en el estudio CNTO328MCD2001, también serán elegibles los que hayan recibido siltuximab durante menos de 4 meses después del cambio de tratamiento. -Parámetros analíticos adecuados en las 2 semanas previas a la primera dosis de siltuximab en relación con este protocolo |
|
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 |
-Toxicidad incontrolable, acontecimiento adverso, progresión de la enfermedad o retirada del consentimiento como motivo de la suspensión del tratamiento en un estudio de siltuximab anterior iniciado por el promotor. -Vacunación con vacunas de microorganismos vivos atenuados en las 4 semanas previas a la primera dosis de este estudio. -Alergias, hipersensibilidad o intolerancia conocidas y no controlables a anticuerpos monoclonales, a proteínas murinas, quiméricas o humanas o a sus excipientes. |
