Novocure LtdPhase 3 TRIDENT trial failed to meet primary overall survival endpoint in glioblastoma

Novocure announced that its Phase 3 TRIDENT trial did not meet its primary endpoint of a statistically significant improvement in overall survival for newly diagnosed glioblastoma patients who started Tumor Treating Fields therapy at the beginning of chemoradiation compared to those who started during the maintenance phase. In the intent-to-treat population, median overall survival was 17.7 months in the early start arm versus 17.5 months in the maintenance start arm, with a hazard ratio of 0.953 and a p-value of 0.519. The trial enrolled 981 patients and showed durable survival in both arms, with one-, two-, and three-year survival rates of 70.9%, 33.9%, and 22.5% in the early start arm, and 72.0%, 31.6%, and 18.4% in the maintenance start arm. No new safety signals were observed, and early initiation of TTFields therapy was feasible. The results have been accepted for presentation at the American Society for Radiation Oncology 2026 Annual Meeting.
