To investigate the lack of clinical responses across indications, MAGE-A10 protein expression in tumor cells pre- and post-infusion, PD-L1 protein expression in tumor and stromal cells pre- and post-infusion, CD3+ T-cell, CD8+ T-cell, T-cell exhaustion, and antigen processing machinery gene expression pre-infusion were evaluated in accordance with tumor sample availability. The gene discussed is CD274; the disease is neoplasm.
