Recurrent WHO Grade 2 Glioma

This phase II trial tests how well erdafitinib works in controlling IDH-wild type (WT), FGFR-TACC gene fusion positive gliomas that have come back after a period of improvement (recurrent) or that are growing, spreading, or getting worse (progressive). Erdafitinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal FGFR protein that signals tumor cells to multiply. This may help keep tumor cells from growing and may kill them. Giving erdafitinib may help to slow the growth of, or to shrink, tumor cells in patients with recurrent or progressive IDH-wild type gliomas with FGFR-TACC gene fusion.

This phase I trial tests the safety, side effects, and best dose of triapine in combination with temozolomide in treating patients with glioblastoma that has come back after a period of improvement (recurrent). Triapine inhibits an enzyme responsible for producing molecules required for the production of deoxyribonucleic acid (DNA), which may inhibit tumor cell growth. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Giving triapine in combination with temozolomide may be safe, tolerable, and/or effective in treating patients with recurrent glioblastoma.
