Imvax Seeks FDA Path for IGV-001 After 6-Month Survival Gain in Glioblastoma
SHERIDAN, WYOMING - December 2, 2025 - Imvax is moving its autologous glioblastoma immunotherapy IGV-001 toward the FDA, despite a missed primary endpoint in Phase IIb, betting that a six-month overall survival benefit and a novel "synergistic" treatment concept will resonate in a setting where outcomes have barely budged in two decades.
Phase IIb data highlight survival benefit despite PFS miss
In a mid-stage trial of 99 patients with newly diagnosed glioblastoma, Imvax evaluated IGV-001, a biologic-device combination, against placebo. While the study did not achieve its primary endpoint of improving progression-free survival, the company reported a median overall survival of 20.3 months in the treatment arm-around six months longer than in the control group.
