  Purpose: Antibodies that target immune checkpoint molecules have demonstrated significant and durable clinical benefit through re-activation and proliferation of pre-existing tumor-infiltrating CD8+ T cells in a broad range of tumor types including lung cancer. Detailed characterization of T cell dynamics at clonal levels using nextgeneration T cell receptor (TCR) sequencing in large cohorts of lung cancer patients is yet reported. Methods: We performed TCR sequencing of peripheral blood samples (and some tumors) obtained from 27 lung cancer patients undergoing single/combined immune checkpoint blockade therapies. Results: In one responder, we found expansion of a single T cell clone (approximately 20% of the all TCR reads) in a metastatic subcutaneous lesion that showed pathologic complete response on day 17 of treatmen..
