Senicapoc and Perampanel for Newly Diagnosed Glioblastoma

Glioblastoma is the most common and aggressive form of brain cancer in adults. Despite surgery, radiotherapy, and chemotherapy, most patients only live about one year after diagnosis. There is an urgent need for new and better treatments. Recent research has shown that glioblastoma cancer cells communicate with surrounding brain cells through electrical signals that help the tumor grow and resist treatment. Two existing drugs, perampanel (used for epilepsy) and senicapoc (previously tested for blood disorders), may block these harmful signals. Laboratory studies suggest that combining these two drugs could slow tumor growth and make cancer cells more sensitive to standard therapy. The SENIPERA trial will test whether perampanel and senicapoc, alone and in combination, are safe and well tolerated when added to standard treatment for newly diagnosed glioblastoma. The study will also measure how well these drugs reach the brain and tumor, and how they affect tumor biology. The study has two parts: Part A: Tests different doses of senicapoc alone to find the maximum tolerable dose. Part B: Randomly assigns patients to receive either perampanel alone or perampanel together with senicapoc. Participants will all receive standard therapy, including surgery, radiochemotherapy, and adjuvant chemotherapy. During surgery, small samples of tumor and fluid will be collected safely to study how the drugs act in the body and how tumor cells respond. Participants will be closely monitored for side effects and followed with regular clinical visits and MRI scans. The trial will take place at Aarhus University Hospital, Denmark, from February 2026 to November 2028 and will enroll 27-36 adult patients. The study aims to identify safe and biologically active treatment combinations that could be tested in larger trials to improve future glioblastoma care.
