Intervention / Treatment
Detailed Description
This research study will assign a specific drug treatment based on lab tests performed on the participant's tumor from tumor tissue taken from a biopsy done when he/she was first diagnosed or if taken when he/she relapsed or progressed. All participants will get Temozolomide and Etoposide to start. Then depending on review of the participant's tumor tissue he/she will also receive one of the following: Sorafenib, Everolimus, Erlotinib, or Dasatinib.
The purpose of this research study is to learn about the feasibility of obtaining and using information from studies done on tumor tissue in order to help make treatment decisions for patients with relapsed or refractory pediatric brain tumors. The investigators also want to find out the effects this therapy has on the participant and the participant's brain tumor.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
EXPERIMENTAL: Regimen B
Depending on tumor biology testing, subjects assigned to Regimen B will receive: Temozolomide 150 mg/m2/dose daily PO on days 1-5, Etoposide 50 mg/m2/dose daily PO on days 1-12, and Everolimus 3 mg/m2/dose daily PO on days 1-28. Cycles will be repeated every 28 days for up to 12 cycles. |
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.
Other Names:
Temozolomide combined with Etoposide is considered the "best available" combination of low-dose oral cytotoxic agents for patients with refractory or recurrent CNS tumors.
Other Names:
Etoposide combined with Temozolomide is considered the "best available" combination of low-dose oral cytotoxic agents for patients with refractory or recurrent CNS tumors.
