"We continue to progress our mission to develop T-cell therapies that can outlast and eradicate solid tumors," said Liz Homans, CEO of Lyell Immunopharma. "Our multi-modal pipeline has advanced two products into Phase 1 clinical development, and we remain on track to submit an IND in the second half of this year for LYL845, our wholly owned TIL product candidate, and with our collaborators at GSK we remain on track to submit an IND for LYL331, a next-generation NY-ESO-1 T-cell receptor product candidate in late 2022 – early 2023. We remain focused on executing towards clinical data, and our strong financial position enables us to see our current pipeline through key milestones in evaluating T-cell exhaustion and lack of durable stemness as key barriers to successful cell therapy in patients with solid tumor cancers."

Recent Business Highlights

Announced two upcoming abstract presentations at the 25th Annual Meeting of the American Society of Gene & Cell Therapy (ASGCT) (Free ASGCT Whitepaper), scheduled for May 16 – 19, 2022, in Washington, DC. The presentations will highlight preclinical data characterizing two investigational products in Phase 1 clinical development, LYL797 and LYL132, that incorporate Lyell reprogramming technologies designed to address major barriers to successful adoptive cell therapy.
Presented preclinical data characterizing LYL797 at the Association for Cancer Research (AACR) (Free AACR Whitepaper) 2022 Annual Meeting. LYL797 is a receptor tyrosine kinase-like orphan receptor 1 (ROR1)-targeted CAR T-cell therapy that incorporates Lyell’s genetic and epigenetic reprogramming technologies, Gen-R and Epi-R, designed to overcome T-cell exhaustion and promote durable stemness.
Initiated screening for the Phase 1 clinical trial for LYL797. The trial is designed to be an open label dose escalation and expansion trial that initially enrolls patients with relapsed/refractory triple‑negative breast cancer or non-small cell lung cancer who have failed at least two lines of therapy. Initial data is expected in 2023.
Announced FDA clearance of the IND for LYL132, a next-generation T-cell receptor (TCR) therapy for patients with solid tumors expressing New York esophageal squamous cell carcinoma 1 (NY-ESO-1) that incorporates Epi-R.
Expanded executive management team with the appointment of veteran biotech leader Gary Lee, Ph.D. as Chief Scientific Officer. With more than a decade of experience heading translational cell and gene therapy programs, Dr. Lee sets and oversees the company’s research strategy and pipeline.
First Quarter 2022 Financial Results

GAAP and Non-GAAP Operating Results

Lyell reported a net loss of $68.1 million for the first quarter ended March 31, 2022, compared to a net loss of $55.0 million for the same period in 2021. Non-GAAP net loss, which excludes non-cash stock-based compensation and non-cash expenses related to the change in the estimated fair value of success payment liabilities, was $50.0 million for the first quarter ended March 31, 2022 compared to $32.3 million for the same period in 2021.
Research and development (R&D) expenses were $35.8 million for the first quarter ended March 31, 2022, compared to $41.5 million for the same period in 2021. The decrease in R&D expense was primarily driven by a reduction in the success payment liability balance, which offset increases in infrastructure and personnel costs to support the expansion of our R&D and manufacturing capabilities. Non‑GAAP R&D expenses, which exclude non-cash stock-based compensation and non-cash expenses related to the change in the estimated fair value of success payment liabilities for the first quarter ended March 31, 2022, were $35.9 million, compared to $26.7 million for the same period in 2021.
General and administrative (G&A) expenses were $34.4 million for the first quarter ended March 31, 2022, compared to $16.8 million for the same period in 2021. The increase in G&A expense was primarily due to a $10.4 million increase in stock-based compensation expense, primarily related to award modifications and new awards granted. Non‑GAAP G&A expenses, which exclude non-cash stock-based compensation, for the first quarter ended March 31, 2022 were $16.2 million, compared to $9.0 million for the same period in 2021. The increase in non-GAAP G&A expenses was driven by litigation-related expenses and public company operating costs.
A discussion of these non-GAAP financial measures, including reconciliations of the most comparable GAAP measures to non-GAAP financial measures, is presented below under "Non-GAAP Financial Measures."

Cash, cash equivalents and marketable securities

Cash, cash equivalents and marketable securities as of March 31, 2022 were $838.0 million, compared to $898.3 million as of December 31, 2021. Lyell believes that its cash, cash equivalents and marketable securities balances will be sufficient to meet working capital and capital expenditure needs into 2025.
