SIOP Ependymoma II: An International Clinical Program for the diagnosis and treatment of children, adolescents and young adults with ependymoma
EU CTIS ID: 2024-512222-28-00
What this study is testing
Overall program : To determine whether the assessment of residual disease can be improved by a centralized review of post-operative MRI and whether such review increases the rate of complete resection compared to historical controls. Does central neurosurgical and radiological review increase resection rates? Stratum 1: To compare progression-free survival (PFS) in patients who receive 16 weeks of chemotherapy (VEC+CDDP) following complete surgical resection and radiotherapy to those who undergo complete surgical resection and radiotherapy alone. Stratum 2: To compare the activity of 2 post-operative chemotherapy schedules with VEC or VEC+HD-MTX in patients who have incompletely resected tumour. Stratum 3: To evaluate the progression free survival in children unable to receive radiation therapy and who receive valproate, as a histone deacetylase inhibitor in addition to the primary chemotherapy strategy when compared to those that undergo chemotherapy without valproate.
