Dr. Stupp on Final Results for TTFields Added to Chemo in Glioblastoma

Roger Stupp, MD, professor, Neurological Surgery, and associate director, Strategic Initiatives, Robert H. Lurie Comprehensive Cancer Center, Northwestern University, discusses final results of a randomized, multi-center, phase III trial investigating tumor treating fields (TTFields) added to standard chemotherapy in newly diagnosed glioblastoma during the AACR Annual Meeting.

This study aimed to improve survival in glioblastoma, which is the most aggressive and malignant primary brain tumor in adults. The study involved 80 centers worldwide and randomized a total of 695 patients to receiving either standard of care — either temozolomide/radiation, followed by temzolomide, or temozolomide/radiation, followed by temozolomide plus TTFields.

The results demonstrated a 37% reduction in risk of death when adding TTFields to temozolomide/chemotherapy. To illustrate those results at 2 years, this means the overall survival is increasing from 30% to 43%, and there is a maintenance of this absolute benefit at 3, 4, and even 5 years, Stupp explains.
