Study: NCT02015728

Intervention type: DEVICE
Group type: EXPERIMENTAL
Intervention: Tumor biology testing
Description: Tumor biology studies will be performed in a CLIA-approved clinical pathology laboratory using standard procedures. Immunohistochemical (IHC) testing will be performed on formalin fixed tumor obtained at the time of diagnosis and/or relapse. Results will be interpreted by a qualified pediatric pathologist and will be scored on a scale of 0 to 4+ commenting on both percentage of positive cells and intensity of staining. Results will further be reported as a binary result (positive/negative). If more than one tumor specimen is available from different surgical procedures (e.g. initial diagnosis and relapse), the results from the relapse specimen will be prioritized. Results will determine kinase inhibitor treatment arm assignment which will be administered in addition to the best available combination of low-dose oral cytotoxic agents, including temozolomide and etoposide.

Group type: EXPERIMENTAL
Intervention: Temozolomide
Description: Temozolomide combined with Etoposide is considered the best available combination of low-dose oral cytotoxic agents for patients with refractory or recurrent CNS tumors.
