About Lyell

Lyell is a clinical-stage T-cell reprogramming company advancing a diverse pipeline of cell therapies, including three product candidates in or entering Phase 1 clinical development for patients with solid tumors or hematologic malignancies. Lyell’s product candidates are enhanced with novel anti-exhaustion technology designed to address barriers that limit consistent and long-lasting responses to cell therapy for solid tumors: T-cell exhaustion and lack of durable stemness, which includes the ability to persist and self-renew to drive durable tumor cytotoxicity. Lyell applies its proprietary ex vivo genetic and epigenetic reprogramming technology to address these barriers to develop new medicines with improved durable clinical outcomes. Lyell is based in South San Francisco, California with facilities in Seattle and Bothell, Washington. To learn more, please visit www.lyell.com.
