Allogeneic iPSC-derived iNKT cells in recurrent head and neck cancer: a phase 1 trial.

ABSTRACT: Invariant Natural killer T (iNKT) cells exhibit cytotoxic activity and immunomodulatory functions and have gained interest in cancer immunotherapy. We conducted a phase 1, first-in human clinical trial to evaluate the safety and efficacy of clinical-grade allogeneic iNKT cells generated from induced pluripotent stem cells (iPSC-iNKT cells) in patients with recurrent head and neck cancer (jRCT2033200116). The primary endpoint was the incidence of dose-limiting toxicity (DLT). The secondary endpoints were to assess safety and efficacy, as well as to evaluate immunological dynamics. iPSC-iNKT cells were administered intra-arterially to 10 patients. One subject developed grade 3 skin rash at the second dose, identified as DLT. No other severe adverse events were observed in any patients. Tumor
