Brief 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.

Outcome Measures

Primary Outcomes (2)

• Completion of 3 cycles

  Will evaluate feasibility of serially screening multiple candidate therapies or combinations based on individualized empiric biological feedback from biospecimens and imaging. This will be measured as the percentage of patients successfully completing 3 cycles of drug administration (study visits). A cycle is 35 +/- 7 days. Regimen will be considered feasible if at least 2/3 of patients can achieve this target.

  Up to 16 weeks

• Turnaround time for scan and marker data

  Will also evaluate feasibility as the turnaround time for scan and marker data that is used to determine if patients should stay on current therapy or move to the next regimen. The outcomes will be cycle-specific. A cycle is 35 +/- 7 days. The target for this is a mean turnaround time of 3 days; if the maximum turnaround time exceeds 5 days, this will prompt an evaluation of process to identify barriers.

  Up to 16 weeks (completion of 3 cycles)

Secondary Outcomes (6)

• Incidence of adverse events

  Up to 3 years

• Change in senescence-associated proteins

  Baseline; up to 3 years

• Cell-free mitochondrial deoxyribonucleic acid (DNA)

  Baseline; up to 3 years

• 2-Hydroxyglutarate (2-HG)
