520 |a We conducted a phase I study of the trans-bronchial injection of α-galactosylceramide (αGalCer)-pulsed antigen presenting cells (APCs) to evaluate their safety, immune responses, and anti-tumor activities. Patients with advanced or recurrent non-small cell lung cancer (NSCLC) refractory to standard treatments were eligible. αGalCer-pulsed APCs were administered intratumorally or intranodally by bronchoscopy. Twenty-one patients were enrolled in this study. No severe adverse events related to the cell therapy were observed during this study in any patient. After αGalCer-pulsed APCs were administrated, increased iNKT cell numbers were observed in PBMCs from eight cases, and IFN-γ producing cells were increased in the peripheral blood of 10 cases. Regarding clinical responses, one case exhibited a partial response and eight were classified as stable disease. In the tumor microenvironment, IFN-γ expression was upregulated after treatment in partial response or stable disease cases and TGF-β was upregulated in progressive disease cases
