Glioblastoma Clinical Trial Landscape

Data updated: May 20, 2026

964 clinical trials tracked since 2008

Glioblastoma is an aggressive type of cancer that occurs in the brain or spinal cord. As the most common malignant primary brain tumor in adults, it represents a significant area of unmet medical need. The clinical trial landscape for glioblastoma is active, with 966 trials registered since 2008, and 354 currently active. Activity is concentrated in early-phase trials, with 195 active Phase 1 and 208 active Phase 2 trials, compared to 31 active Phase 3 trials. This suggests a strong focus on early-stage investigation of novel therapeutic approaches. Industry sponsorship is distributed across multiple organizations, with Novartis and Philogen S.p.A. each sponsoring 3 active trials. Telix Pharmaceuticals (Innovations) Pty Limited, Cantex Pharmaceuticals, and GT Medical Technologies, Inc. are also active sponsors, each with 2 ongoing trials. The relatively small number of Phase 4 trials (4 active) suggests a limited number of therapies progressing to confirmatory studies and real-world evidence generation.
