ERY974 exerts strong anti-tumor activity against a variety of tumor models including those with a non-inflamed phenotype. In this talk, I will discuss the detailed preclinical characterization of ERY974, including the cytokine release mechanism and potential combination therapies.
The observed responses and CRS side effects are markers of ERY974 biologic activity. At doses below 0.81 μg/kg (regimen A), ERY974 was generally well tolerated with a manageable toxicity profile, including ERY-induced CRS which was manageable with steroid administration and anti-IL6R therapy. Further research is required to determine if combined prophylactic anti-IL6R and steroid therapy is a more effective strategy for managing CRS.
