Lyell Immunopharma secures $80 million private placement to fund CAR‑T trials

Lyell Immunopharma entered a securities purchase agreement to sell roughly 7.4 million common shares, raising about $80 million. The financing, backed by investors such as ARCH Venture Partners, Adage Capital, Caligan Partners and RTW Investments, is expected to extend the company’s cash runway into 2028. The proceeds will support pivotal data generation for ronde‑cel and the regulatory filing of a Biologics License Application in the second half of 2027, as well as development of its LYL273 program. The transaction is slated to close on November 4, 2026.

The company says the cash will be sufficient to meet working‑capital and capital‑expenditure needs through 2028, covering key clinical milestones and the anticipated BLA submission. Extending the runway reduces immediate financing risk for investors.
