Here, we report the successful generation and expansion of TIL engineered with regulatable, membrane-bound IL15 (cytoTIL15™ cells) from immune-excluded, paucicellular chondrosarcoma biopsies largely consisting of collagenous matrix and demonstrate that these cells have potent tumor-killing capacity in cell culture and in tumor spheroid models in the absence of exogenous IL2...Moreover, we demonstrate that IL15 reduced the signaling threshold of T-cell receptors isolated from TIL clonotypes, increasing their infiltration and cytotoxicity in autologous 3D tumor models. These results suggest the possibility of developing an effective IL2-free TIL therapy for patients with immune-excluded tumors.
