The California company, based in South San Francisco, was founded in 2018 by Rick Klausner, former director of the National Cancer Institute and the co-founder of Juno Therapeutics Inc., according to Lyell’s filings. Lyell describes itself as “a T cell reprogramming company dedicated to the mastery of T cells to cure patients with solid tumors.”
