E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Patient has advanced (loco-regionally recurrent not amenable to curative therapy or metastatic) breast cancer. • Patient must have measurable disease, i.e., at least one measurable lesion as per RECIST 1.1 criteria (Tumor lesions previously irradiated or subjected to other loco-regional therapy will only be considered measurable if disease progression at the treated site after completion of therapy is clearly documented) • Patient progressed after adjuvant or 1 prior systemic treatment in the metastatic setting. Patients with de novo metastatic disease are eligible if they received 1 prior line of therapy • Patient must have received prior systemic treatment that included taxane-based chemotherapy for adjuvant or metastatic disease • Patient must have a site of disease amenable to biopsy, and must be willing to undergo a new tumor biopsy at screening and during therapy on this study, the latter if medically feasible. Patients with an available archival tumor tissue do not need to perform a tumor biopsy at screening if patient has not received anti-cancer therapy since the biopsy was taken. • Patient has histologically and/or cytologically confirmed diagnosis of TNBC (based on most recently analyzed biopsy, local lab) meeting the following criteria: HER2 negative in situ hybridization test or an IHC status of 0 or 1+, and ER and PR expression is <1 percent as determined by immunohistochemistry (IHC)
Other protocol-defined inclusion criteria may apply |
-Pacientes con cáncer de mama avanzado (locorregionalmente recurrente no susceptible de recibir tratamiento curativo o metastásico). -Pacientes con enfermedad medible, es decir, al menos una lesión medible según los criterios RECIST v1.1 (las lesiones tumorales previamente irradiadas o sometidas a otro tratamiento locorregional solo se considerarán medibles si la progresión de la enfermedad en el lugar tratado después de la finalización del tratamiento está claramente documentada). -Pacientes que hayan progresado tras el tratamiento adyuvante o tras una línea previa de tratamiento sistémico para la enfermedad metastásica. Los pacientes con enfermedad metastásica de novo son elegibles si han recibido una línea previa de tratamiento. -Pacientes que hayan recibido tratamiento sistémico previo que incluyera quimioterapia basada en taxanos para la enfermedad adyuvante o metastásica. -Pacientes con una zona de enfermedad en la que pueda realizarse una biopsia y dispuestos a que se les realice una nueva biopsia del tumor en la selección y durante el tratamiento de este estudio, este último si es médicamente factible. Los pacientes con un tejido tumoral archivado disponible no deben someterse a una biopsia tumoral en la selección si no han recibido tratamiento contra el cáncer desde que se realizó la biopsia. -Pacientes con diagnóstico histológica o citológicamente confirmado de CMTN (basado en la biopsia analizada más recientemente, laboratorio local) que cumpla los siguientes criterios: HER2 negativo en la prueba de hibridación in situ o un estado 0 o 1+ de IHQ, y expresión de ER y PR < 1 % según la determinación mediante inmunohistoquímica (IHQ). Se pueden aplicar otros criterios de inclusión definidos por el protocolo. |
