A Phase 2 Study of Sotigalimab, a CD40 Agonist Antibody, plus Concurrent Chemoradiation as Neoadjuvant Therapy for Esophageal and Gastroesophageal Junction Cancers

The current study represents the first report to evaluate a CD40 agonist antibody in combination with concurrent chemoradiation in the neoadjuvant setting for patients with esophageal/GEJ cancers. This novel strategy was both safe and feasible, producing encouraging path CR rates that compare favorably with historical data. Our findings support the further evaluation of how immune-based therapies may be incorporated into perioperative treatment paradigms for upper gastrointestinal malignancies.
