Lyell is advancing next-generation fully-armed CAR T-cell product candidates, meaning they are armed with multiple technologies, each designed to address different barriers to effective cell therapies, including T-cell exhaustion, lack of durable stemness, as well as immune suppression within the hostile tumor microenvironment. • During the past year, we presented nonclinical and clinical data from our suite of anti-exhaustion and manufacturing technologies demonstrating their potential to improve T-cell function in solid tumors. • We presented data at the Society for Immunotherapy of Cancer (SITC) 2024 from a validated nonclinical xenograft model of non-small cell lung cancer, demonstrating that combining c-Jun overexpression and NR4A3 knockout achieves tumor control and prolonged survival even at very low doses (100,000 CAR T cells/dose) compared to c‑Jun overexpression alone (1,000,000 CAR T cells/dose).
