MC230715 Pilot Study of the Mechanistic Feedback From CNS Tumors With Latent Residual Disease to Guide Individualized Therapies

Status: Recruiting
Location: See location...
Intervention Type: Drug, Procedure, Other
Study Type: Interventional
Study Phase: Early Phase 1
SUMMARY

This early phase I trial tests the safety, side effects and how well medication combinations of dasatinib, quercetin, fisetin and temozolomide work in treating patients with glioma for which the patient has received treatment in the past (previously treated) and for tumor cells that remain after attempts to treat the tumor have been made (residual disease). Dasatinib is in a class of medications called tyrosine kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply, which may help keep tumor cells from growing. Quercetin and fisetin are compounds found in plants. They have antioxidant and anti-inflammatory properties and help remove senescent cells, older or damaged cells that have stopped dividing but don't die off as they should and build up in tissues over time. Senescent cells may cause inflammation or damage to nearby healthy cells. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid (DNA) and may kill tumor cells and slow down or stop tumor growth. Giving medication combinations of dasatinib, quercetin, fisetin and temozolomide may be safe, tolerable and/or effective in treating patients with previously treated glioma with residual disease.

Treatments
Active_comparator: Regimen 1 (rest, no treatment)
Patients receive rest and take no treatment on days 1-35 of cycle 1. Patients at the end of cycle 1 proceed to regimen 2. Additionally, patients undergo MRI throughout the study as well as undergo blood and CSF sample collection on study. Patients may undergo 18F-DOPA-PET scans on study.
Experimental: Regimen 2 (dasatinib, quercetin)
Patients receive dasatinib PO QD on days 1-2 and quercetin PO QD on days 1-2 of each cycle. Cycles repeat every 35 days in the absence of disease progression or unacceptable toxicity. Patients without a PR or CR on imaging at the end of cycle 1 proceed to regimen 3. Patients with a PR or CR may remain on the current regimen. Additionally, patients undergo MRI throughout the study as well as undergo blood and CSF sample collection on study. Patients may undergo 18F-DOPA-PET scans on study.
Experimental: Regimen 3 (fisetin)
Patients receive fisetin PO QD on days 1-2 of each cycle. Cycles repeat every 35 days in the absence of disease progression or unacceptable toxicity. Patients without a PR or CR on imaging at the end of cycle 1 proceed to regimen 4. Patients with a PR or CR may remain on the current regimen. Additionally, patients undergo MRI throughout the study as well as undergo blood and CSF sample collection on study. Patients may undergo 18F-DOPA-PET scans on study.
Experimental: Regimen 4 (temozolomide)
Patients receive temozolomide PO QD on days 1-5 of each cycle. Cycles repeat every 35 days in the absence of disease progression or unacceptable toxicity. Patients without a PR or CR on imaging at the end of cycle 1 proceed to regimen 5. Patients with a PR or CR may remain on the current regimen. Additionally, patients undergo MRI throughout the study as well as undergo blood and CSF sample collection on study. Patients may undergo 18F-DOPA-PET scans on study.
Experimental: Regimen 5 (dasatinib, quercetin, temozolomide)
Patients receive temozolomide PO QD on days 1-5, quercetin PO QD days 14-15 and dasatinib PO QD on days 14-15 of each cycle. Cycles repeat every 35 days in the absence of disease progression or unacceptable toxicity. Patients without a PR or CR on imaging at the end of cycle 1 proceed to regimen 6. Patients with a PR or CR may remain on the current regimen. Additionally, patients undergo MRI throughout the study as well as undergo blood and CSF sample collection on study. Patients may undergo 18F-DOPA-PET scans on study.
Experimental: Regimen 6 (fisetin, temozolomide)
Patients receive temozolomide PO QD on days 1-5 and fisetin PO QD on days 14-15 of each cycle. Cycles repeat every 35 days in the absence of disease progression or unacceptable toxicity. Patients without a PR or CR on imaging at the end of cycle 1 proceed to end of study treatment and study follow up. Patients with a PR or CR may remain on the current regimen.
