Clinical Trial Summary

This trial is an open-label, single-arm, phase 0/1 study of high-grade glioma that aims to evaluate the feasibility, preliminary efficacy and safety of the precision treatment strategy.

Description:

The investigators have established a precision treatment strategy, that select chemotherapeutic drugs or targeted drugs based on information from PTCs drug-screening or/and bioinformatic prediction. In this study, the investigators are going to exploit this strategy for the precision treatment of recurrent high-grade gliomas. The investigators will evaluate the feasibility, safety and preliminary efficacy via collecting the indexes comprising clinical presentation, results of imaging examination, clinical assays, KPS, neurological score, etc.

Intervention

Drug:
• Receiving chemotherapeutic or targeted drugs recommended by molecular tumor board.
Patients will be treated with FDA-approved chemotherapeutic or targeted drugs which were recommended by the molecular tumor board (MTB), based on their expertise, patients willingness as well as evidences from PTCs-drug screening and bioinformatic prediction for drug response.
