Coherus Oncology, Inc. has released encouraging interim clinical data regarding its investigational drug, tagmokitug, as part of its TREGCHECK™ development program. This announcement, made on October 28, 2026, is significant as it showcases the potential effectiveness of tagmokitug in combination with toripalimab, with or without chemotherapy, in treating esophageal cancer.

The interim results indicate strong anti-tumor activity across multiple solid tumors, particularly in patients with esophageal squamous cell carcinoma (ESCC). The combination treatment achieved a confirmed overall response rate (cORR) of 75% in evaluable front-line ESCC patients, with a remarkable 100% response rate in patients who tested positive for PD-L1. Following the data cutoff, the overall response rate improved to 89% across the evaluable patient dataset.
