Tovecimig Demonstrates Statistically Significant PFS Benefit but misses the OS benefit in COMPANION-002 Ph 2/3 Study in Patients with Biliary Tract Cancer

“In this study, tovecimig showed an impressive overall response rate which translated into a clinically meaningful and highly statistically significant improvement in PFS for patients with previously treated BTC. The remarkable 56% reduction in the risk of disease progression is unprecedented in this patient population without an actionable mutation in their tumor,” said Thomas Schuetz, MD, PhD, Chief Executive Officer of Compass. “It is also notable that the 31 crossover patients survived a median of 12.8 months, similar to the median OS seen in front-line studies in this setting. Including crossover, 85% of patients in the study received tovecimig in combination with paclitaxel and the pooled median OS for all patients in the study was 8.9 months, which is also substantially longer than chemotherapy benchmarks of approximately 6 months.”
