Lyell Immunopharma

Lyell Immunopharma is a clinical-stage cell therapy company founded in 2018 by Rick Klausner and publicly traded on Nasdaq. The company focuses on next-generation CAR-T therapies that address the key limitations of first-generation products, particularly the exhaustion and dysfunction of engineered T cells that limits efficacy especially against solid tumors. Lyell has developed proprietary T cell reprogramming technologies including gene overexpression approaches that maintain T cell stemness and fitness during manufacturing and after infusion. The company is applying these technologies to both hematological malignancies and solid tumors in a pipeline of clinical programs. Lyell has established a research collaboration with GlaxoSmithKline to combine cell therapy expertise. While first-generation CAR-T products have demonstrated remarkable responses in blood cancers, Lyell is focused on the much larger unmet need in solid tumors where current CAR-T therapies have shown limited efficacy. The company represents the scientific evolution of the cell therapy field toward more durable and broadly applicable treatments.
