About OBX-115
Obsidian's lead investigational cytoTIL15tm program, OBX-115, is a novel engineered tumor-derived autologous T cell immunotherapy (tumor-infiltrating lymphocyte [TIL] cell therapy) armored with pharmacologically regulatable membrane-bound IL15 (mbIL15). OBX-115 has the potential to become a meaningful therapeutic option for patients with advanced or metastatic melanoma and other solid tumors by leveraging the expected benefits of mbIL15 and Obsidian's proprietary, differentiated manufacturing process to enhance persistence, antitumor activity, and clinical safety of TIL cell therapy. OBX-115 is being investigated in two ongoing clinical trials in advanced or metastatic melanoma and non-small cell lung cancer (NSCLC) (NCT05470283 and NCT06060613).
