Resumen

El propósito de este estudio de fase 2/3, aleatorizado, multicéntrico, abierto, de confirmación de dosis y expansión, es evaluar la seguridad y eficacia de zilovertamab vedotin (ZV) en combinación con opciones de tratamiento estándar para el tratamiento del LDCBG r/r. Este estudio se dividirá en 2 partes: Confirmación de dosis (Parte 1) y Expansión de eficacia (Parte 2), e incorporará participantes mayores de 18 años con LDCBG r/r. Las hipótesis son: ZV en combinación con rituximab, gemcitabina y oxaliplatino (R-GemOx) es superior a R-GemOx con respecto a la supervivencia libre de progresión (SLP) según los criterios de respuesta de Lugano evaluados por un comité de revisión independiente ciego (BICR); y que ZV en combinación con bendamustina y rituximab (BR) es superior a BR con respecto a la SLP según los criterios de respuesta de Lugano evaluados por el BICR. Con la enmienda de protocolo 4 (vigente desde el 4 de abril de 2024), se discontinúa la incorporación en la Cohorte B (brazos del estudio con Bendamustina y Rituximab [BR] y ZV + BR). No se realizará ningún análisis de resultados de eficacia ni pruebas de hipótesis para la Cohorte B.
