Randomized Phase II Trial of Anti-Lag-3 and Anti-PD-1 Blockade vs. SOC in Patients With Recurrent Glioblastoma

This phase II trial compares the safety, side effects and effectiveness of anti-lag-3 (relatlimab) and anti-PD-1 blockade (nivolumab) to standard of care lomustine for the treatment of patients with glioblastoma that has come back after a period of improvement (recurrent). Relatlimab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body’s immune system attack the tumor, and may interfere with the ability of tumor cells to grow and spread. Lomustine is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell’s deoxyribonucleic acid and may kill tumor cells. Giving relatlimab and nivolumab may be safe, tolerable, and/or effective compared to standard of care lomustine in treating patients with recurrent glioblastoma.
