Brain Tumor Clinical Trial Landscape

Data updated: May 20, 2026

781 clinical trials tracked since 2008

Brain tumors are abnormal growths of cells within the brain, which can be cancerous or non-cancerous, and affect both adults and children. Clinical research is crucial for developing new and improved treatments for these complex conditions. Since 2008, 777 brain tumor trials have been registered, with 310 currently active, meaning they are recruiting, enrolling, or active but not recruiting patients. The majority of active trials are in early phases of development, with 178 in Phase 1 and 144 in Phase 2. Phase 3 trials account for 34 active trials, while Phase 4 has 7. Industry sponsorship is distributed across multiple companies, with Pfizer and InSightec leading with 3 active trials each. Jazz Pharmaceuticals, Novartis, and Eli Lilly each have 2 active trials in this space. The high volume of Phase 1 and 2 trials suggests a strong focus on early-stage investigation of novel therapies for brain tumors.
