Corvus Pharmaceuticals presents data on ciforadenant's potential to overcome anti-PD1 resistance in mCRPC at SITC 39th Annual Meeting. Studies reveal SPP1+ myeloid cells as critical mediators of immunotherapy resistance, with ciforadenant reducing immunosuppression and enhancing anti-PD1 sensitivity in a murine model. The adenosine gene signature, reflecting adenosine-induced immunosuppression, was elevated in SPP1+ macrophages, supporting ciforadenant's role in shifting to a less immunosuppressive myeloid environment.
