Summit Therapeutics (SMMT) gained in the premarket trading on Wednesday after announcing late-stage trial results that indicated that its lead asset, ivonescimab, licensed from Akeso (AKESF), outperformed durvalumab, a cancer therapy marketed by AstraZeneca (AZN) as Imfinzi.
The topline results were generated from HARMONi-GI1, a Phase 3 China-based trial conducted by its Chinese partner to test ivonescimab plus chemotherapy versus durvalumab plus chemotherapy as a first-line option for advanced biliary tract cancer.
As for its primary endpoint of overall survival, the ivonescimab-based regimen outperformed the durvalumab-based regimen with a statistically significant and clinically meaningful effect, according to an interim analysis.
The bispecific antibody also met the study’s key secondary endpoints of progression-free survival and objective response rate, Summit (SMMT) said, adding that it will present detailed data from the analysis at a future medical event and submit them for publication in a peer-reviewed journal.
