Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
PRIMARY OBJECTIVE:
For pilot phase (CLOSED TO ENROLLMENT):
I. To determine the feasibility of using the results of real-time in vitro drug screening, whole exome sequencing, and RNA sequencing of participant-derived specimens to guide treatment recommendations by a specialized tumor board, in a clinically actionable timeframe, for children and young adults with recurrent medulloblastoma or ependymoma
For efficacy phase:
II. To determine the progression-free survival (PFS) in children and young adults with relapsed medulloblastoma and ependymoma who received the specialized tumor board recommendation and compare to historical cohorts.
SECONDARY OBJECTIVE:
For pilot (CLOSED TO ENROLLMENT) and efficacy phases:
I. To determine the safety and describe the toxicity of treating children and young adults with relapsed medulloblastoma and ependymoma according to a specialized tumor board recommended treatment plan.
EXPLORATORY OBJECTIVES:
Pilot Phase (CLOSED TO ENROLLMENT):
I. To estimate the objective response rate, progression free survival at 6 months (PFS-6) and overall survival (OS) of relapsed medulloblastoma in children and young adults treated with an individualized treatment regimen.
II. To assess Quality of Life (QOL) measures in participants with relapsed medulloblastoma treated with an individualized regimen.
III. To archive tumor and normal DNA from each participant along with serial blood draw following therapies as biospecimens for later studies to determine whether cfDNA sequences in the participant's blood serve as biomarkers of tumor burden, response to therapy, or development of drug resistance.
Efficacy Phase:
I. To determine the overall survival (OS) and objective response rate (ORR) in children and young adults with relapsed medulloblastoma and ependymoma who received the specialized tumor board recommendation and compare to historical cohorts.
II. To generate PDX models of relapsed medulloblastoma and ependymoma to facilitate future in vivo testing of therapeutic agents.
III. To assess the correlation between available genomic data (WES and RNAseq) and patient outcomes, evaluating its potential complementary role in guiding therapeutic decisions alongside the primary drug screening approach.
IV. To archive tumor and normal DNA from each participant along with serial blood draw following therapies as biospecimens for later studies to determine whether cell free DNA (cfDNA) sequences in the participant's blood serve as biomarkers of tumor burden, response to therapy, or development of drug resistance.
V. To assess patient and/or proxy satisfaction with study participation via patient-reported outcome (PRO) measures in the context of race ethnicity and other health related social risks.
VI. To assess on therapy toxicity in the context of race, ethnicity and other health related social risks.
Participants were initially enrolled in a pilot phase (CLOSED TO ENROLLMENT), and additional participants will be enrolled in the efficacy phase. Participants may continue treatment as tolerated for up to two years or until disease progression. After two years, patients may be eligible to continue therapy if they are experiencing clinical benefits, have disease control, and it is deemed appropriate to do so by their physician. Participants will be followed until progression, death, or up to 5 years from start of therapy.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Participants must have surgically accessible disease.
3. Prior Therapy:
1. The participant must have received at least one prior therapy at the time of initial diagnosis.
2. Relapsed medulloblastoma or relapsed ependymoma are eligible.
3. Participants must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study and would be eligible for surgical resection per institutional guidelines
* Participants must have received last chemotherapy or biologic agent at least 7 days prior to registration.
* Monoclonal antibody treatment: \> 21 days prior to registration.
* Bevacizumab participants must have received last dose \> 21 days prior to study registration
4. Participant must be a candidate for surgical resection or biopsy with anticipated ability to obtain the minimum tissue requirements for study.
5. Radiation - Participants must have:
1. Had their last fraction of local irradiation to primary tumor \>= 12 weeks prior to registration.
2. Had their last fraction of craniospinal irradiation or total body irradiation \>= 12 weeks prior to registration
3. At least 14 days after local palliative radiation (small-port)
6. Age \>=12 months to \<= 39 years of age.
7. Karnofsky \>= 50 for participants \> 16 years of age and Lansky \>= 50 for participants \<= 16 years of age. Participants who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
