Recurrent Glioblastoma | Diagnostic Test: ChemoID assay Drug: Chemotherapy | Phase 3 |
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.
Study Type : | Interventional (Clinical Trial) |
Estimated Enrollment : | 150 participants |
Allocation: | Randomized |
Intervention Model: | Parallel Assignment |
Intervention Model Description: | parallel group randomized controlled clinical trial |
Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
Masking Description: | Study investigators will be kept blind to the schedule. All participants will be screened by the ChemoID drug response assay; however, the treating physician will receive the ChemoID results only for those participants who are randomized to ChemoID-guided treatment arm. |
Primary Purpose: | Diagnostic |
Official Title: | Standard Chemotherapy Versus Chemotherapy Chosen by Cancer Stem Cell Chemosensitivity Testing in the Management of Patients With Recurrent Glioblastoma Multiforme (GBM). |
Actual Study Start Date : | May 15, 2018 |
Estimated Primary Completion Date : | June 30, 2023 |
Estimated Study Completion Date : | December 31, 2023 |

Active Comparator: Physician Choice treatment
Participants will be treated with control chemotherapy treatment (standard-of-care chemotherapy chosen by the Physician from the provided list). Control chemotherapy treatment will be chosen from any of the following standard-of-care chemotherapy drugs or combinations:
|
Diagnostic Test: ChemoID assay
The ChemoID test is a CLIA-certified and CAP-accredited drug response assay performed by a hospital clinical pathology laboratory that uses patient's live tumor cells to indicate which chemotherapy agent (or combinations) will kill not only bulk of tumor cells, but importantly the cancer stem cells (CSCs) that are known to cause cancer to recur. During the assay, cancer stem cells and bulk tumor cells from an individual patient are exposed to FDA-approved chemotherapy drugs. The test measures the cytotoxic effect of actual doses of standard-of-care chemotherapies. The ChemoID drug response assay reports a prioritized list of effective and ineffective chemotherapies. The test is designed to target cancer stem cells to mitigate tumor relapse. Drug: Chemotherapy Chemotherapies chosen by Physician or ChemoID assay are in the same list of FDA approved drugs to treat recurrent ovarian cancer
Other Name: Cytotoxic chemotherapy drugs |
Experimental: ChemoID-guided treatment
Participants will be treated with ChemoID-guided standard-of-care chemotherapy drugs from the provided list. ChemoID-guided treatment will be chosen from the following standard-of-care chemotherapy drugs or combinations:
