Inclusion Criteria

  • Age ≥18 and <75 years - Diagnosis of head and neck squamous cell carcinoma with metastatic or unresectable, recurrent disease. confirmed by histology cytology. - Checkpoint inhibitor naïve and indicated for pembrolizumab or currently receiving pembrolizumab (monotherapy). May have received prior platinum containing chemotherapy regimen or checkpoint inhibitor therapy. - Subjects that have already received pembrolizumab (alone or in combination) and are progressing or have completed immune checkpoint inhibitor therapy for recurrent/metastatic disease, may still be enrolled and will skip Part A of the study. These subjects will enroll into Part B when manufactured T cells are available. - Measurable disease according to RECIST v1.1. - HLA-A*02 positive by central laboratory. - Tumor shows MAGE-A4 expression confirmed by central laboratory. - ECOG Performance Status of 0 or 1. - Left ventricular ejection fraction (LVEF) ≥50%.
