Standard Chemotherapy Versus Chemotherapy Chosen by Cancer Stem Cell Chemosensitivity Testing in the Management of Patients With Recurrent Glioblastoma Multiforme (GBM).

Description

Brief Summary
The purpose of this clinical study is to confirm the utility of chemosensitivity tumor testing on cancer stem cells (ChemoID) as a predictor of clinical response in poor prognosis malignant brain tumors such as recurrent glioblastoma (GBM).


Detailed Description
This study is designed as a parallel group randomized controlled clinical trial to determine if recurrent Glioblastoma (GBM) patients treated with drugs predicted by the ChemoID assay will have better outcomes than patients treated with standard-of-care control therapy chosen by the Physician. Upon obtaining informed consent, all eligible participants affected by recurrent GBM will have a tumor biopsy to undergo ChemoID drug response testing with multiple FDA-approved chemotherapeutic agents. Eligible participants will be randomized to a standard treatment arm with control treatment (chemotherapy chosen by the Physician from a provided list), or to a study arm of FDA-approved drugs selected by the ChemoID drug response assay.

  • If indicated radiation therapy and chemotherapy must start within 8 weeks of tumor resection or biopsy. Exclusion Criteria:
  • Subjects with newly diagnosed GBM
  • Pregnant women or nursing mothers cannot participate in the study. Women of childbearing age must have a negative pregnancy test within 72 hours prior to study entry. Women of childbearing potential must practice medically approved contraceptive precautions;
