EGFR/EGFRvIII Inhibitor WSD0922-FU

This phase II trial compares the effect of adding WSD0922-FU to temozolomide versus temozolomide alone in slowing disease progression in patients with Epidermal Growth Factor Receptor (EGFR)-mutant, IDH-wildtype glioblastoma. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's deoxyribonucleic acid and may kill tumor cells and slow down or stop tumor growth. WSD0922-FU is a targeted treatment which blocks EGFR. It is able to get into the brain and spinal cord and help treat those types of tumors. Adding WSD0922-FU to the usual treatment with temozolomide may be more effective in slowing disease progression, compared to temozolomide alone, in patients with EGFR-mutant, IDH-wildtype glioblastoma.
