Brain Slice Explants to Predict Drug Response in Brain Tumors

Study Overview
=================
Brief Summary
-----------------
This biospecimen collection study will evaluate the feasibility of engrafting and testing resected Central nervous system (CNS) tumors tumor tissue ex vivo to estimate drug response, in pediatric and adult subjects. CNS tumors display remarkable heterogeneity and unfortunately there are no reliable precision oncology platforms that can identify the most effective therapy for each patient. Recent work has demonstrated the success of functional precision oncology platforms using patient-derived explant (PDE) at predicting drug response in various cancers. Since PDEs maintain important aspects of tumor heterogeneity they may prove effective as functional models for CNS tumors. The purpose of this study is to explore the feasibility of using a novel PDE platform to generate drug sensitivity scores from patients with central nervous system tumors in Pediatric and adult subjects having low- or high-grade CNS tumors resected. The secondary objective is to estimate the proportion of successfully scaled PDEs generated per given tumor size.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of specimens yielding scores | The proportion of evaluable specimens yielding patient-derived explant (PDE) drug sensitivity scores. Specimens will be collected during surgery for tumor resection. Excised specimens will be processed to generate PDE-based functional drug screening models. A panel of therapeutics will be chosen for each specimen according to pre-set criteria determined. | Up to 28 days | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The scalability of evaluable specimens | The percentage of evaluable specimens amenable to proportionally scaled patient-derived explant (PDE) generation per specimen size will be studied. | Up to 28 days |
