Nivolumab with or without Relatlimab given Prior to Surgery and Temozolomide and Radiation Therapy for the Treatment of IDH Wildtype Newly Diagnosed Glioblastoma

Trial Status: active

This phase II trial tests how well nivolumab, administered alone or in combination with relatlimab, given prior to surgery to remove the brain tumor, followed by nivolumab and relatlimab given after surgery, in combination with standard radiation therapy with or without temozolomide, then followed by nivolumab and relatlimab with or without temozolomide works in treating patients with isocitrate dehydrogenase (IDH) wildtype newly diagnosed glioblastoma (ndGBM). Nivolumab and relatlimab are a type of monoclonal antibody and a type of immune checkpoint inhibitor. The combination of nivolumab and relatlimab binds to the proteins PD-1 and LAG-3, which are found on T cells (a type of immune cell). Blocking these proteins may help the immune system kill tumor cells. The combination of nivolumab and relatlimab may work better than either drug alone. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. Temozolomide (TMZ) 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 nivolumab with or without relatlimab prior to surgery and temozolomide and radiation therapy may work better in treating patients with IDH wildtype newly diagnosed glioblastoma.
