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.
Patient must be >= 18 years of age
Patient must have histologically confirmed IDH-WT gliomas (grade 2-4) as per World Health Organization (WHO) 2016 or 2021 classification
Tumor tissue should be positive for FGFR-TACC gene fusion as per any local next generation sequencing (NGS) (Clinical Laboratory Improvement Act [CLIA]-approved) assay described in background section
The disease should be recurrent or progressive glioma after initial anti-tumor treatment with at least 1 line of treatment including surgical resection, radiation therapy and/or chemotherapy
Patients who are receiving any other investigational agents
History of allergic reactions attributed to compounds of similar chemical or biologic composition to erdafitinib
Patients requiring any medications or substances that are moderate CYP2C9 inducers and strong CYP3A4 inducers are ineligible. Because the lists of these agents are constantly changing, it is important to regularly consult a frequently-updated medical reference. As part of the enrollment/informed consent procedures, the patient will be counseled on the risk of interactions with other agents, and what to do if new medications need to be prescribed or if the patient is considering a new over-the-counter medicine or herbal product
Patients with uncontrolled intercurrent illness
