Los pacientes pueden haber recibido tratamientos previos sin límite para el GBM. 5. Pacientes en los que se pueda retrasar 2 semanas la cirugía con seguridad para ellos, según el criterio del investigador. 6. ECOG 0-1.

Se deberán discontinuar los esteroides o reducirlos a dosis <10 mg de prednisona o equivalente en el momento de la inclusión o durante el tratamiento con nivolumab. No obstante, se permitirán dosis mayores de esteroides para el control del edema cerebral. 9. Función orgánica adecuada, definida por: a. Hematológica: leucocitos: 2000/ mm3; neutrófilos 1500x 109/L; plaquetas100000/ mm3 100 x 109/L; hemoglobina 9.0 g/dL). b. Hepática: bilirrubina <1.5 x límite superior de la normalidad (LSN), AST y ALT <3.0 LSN (BR< 3 x LSN para pacientes con síndrome de Gilbert). c. Renal: creatinina < 1.5 x LSN o aclaramiento estimado de creatinina > 40 ml/min (Cokcroft-Gault). 10. Las mujeres con capacidad reproductiva deberán utilizar métodos adecuados para evitar la concepción durante el tratamiento hasta al menos 23 semanas después de la última dosis de nivolumab. 11. Las mujeres en capacidad reproductiva deberán tener una prueba negativa de embarazo en suero u orina 24 horas antes del comienzo del tratamiento con nivolumab. 12.

E.4 | Principal exclusion criteria |
1. Presence of extracranial disease. 2. Any serious or uncontrolled medical disorder that, in the opinion of the investigator, may increase the risk associated with study participation or study drug administration, impair the ability of the subject to receive the planned therapy (including brain surgery), or interfere with the interpretation of study results. 3.

Subjects with vitiligo, type I diabetes mellitus, residual hypothyroidism due to autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment, or conditions not expected to recur in the absence of an external trigger are permitted to enroll. 4.
