IO102-IO103 is an investigational immune-modulating cancer vaccine designed to target the immunosuppressive mechanisms mediated by the proteins indoleamine 2,3-dioxygenase (IDO) and programmed death-ligand 1 (PD-L1). The company is currently conducting a pivotal Phase 3 trial (IOB-013/KN-D18; NCT05155254) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced melanoma patients, a Phase 2 basket trial (IOB-022/KN-D38; NCT05077709) evaluating IO102-IO103 in combination with pembrolizumab in first-line advanced non-small cell lung cancer and head and neck cancer, and a Phase 2 basket trial (IOB-032/PN-E40; NCT05280314) evaluating IO102-IO103 plus pembrolizumab as a perioperative treatment in solid tumors including Melanoma and Squamous Cell Carcinoma of Head and Neck (SCCHN). The clinical trial is sponsored by IO Biotech and conducted in collaboration with Merck. IO Biotech maintains global commercial rights to IO102-IO103.
About IOB-032/PN-E40 Phase 2 Basket Trial in Solid Tumors
IOB-032/PN-E40, (NCT05280314) is a multi-center, multi-arm basket trial evaluating anti-tumor activity, safety, and immune infiltration of IO102-IO103 in combination with pembrolizumab as neoadjuvant and adjuvant treatment. This proof-of-concept trial will be focused initially on two indications and will include patients with resectable tumors in Melanoma and SCCHN.
IO Biotech is a clinical-stage biopharmaceutical company developing novel, immune-modulating therapeutic cancer vaccines based on its T-win® vaccine platform. The T-win platform is a novel approach to cancer vaccines designed to activate T cells to target the most important immunosuppressive cells in the tumor microenvironment. IO Biotech is advancing in clinical studies its lead cancer vaccine candidate, IO102-IO103, targeting IDO and PD-L1, and through preclinical development its other pipeline candidates. Based on positive Phase 1/2 data, IO102-IO103 has been granted break through designation by the US Food and Drug Administration. IO Biotech is headquartered in Copenhagen, Denmark and has US headquarters in New York, New York.
