Lyell Immunopharma Reports First Quarter Financial Results and Business Highlights

• Cash, cash equivalents and marketable securities of $838 million as of March 31, 2022 supports advancing a robust cell therapy pipeline
• Research highlighting novel reprogramming technologies designed to overcome barriers to successful adoptive cell therapy in solid tumors presented at multiple scientific conferences

SOUTH SAN FRANCISCO, Calif., May 10, 2022 (GLOBE NEWSWIRE) -- Lyell Immunopharma, Inc., (Lyell) (Nasdaq: LYEL), a T-cell reprogramming company dedicated to the mastery of T cells to cure patients with solid tumors, today provided business highlights and reported financial results for the first quarter of 2022.

“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), 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) 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.

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.

About Lyell Immunopharma, Inc.

The Company focuses on addressing what it believes are the primary barriers that limit consistent, reliable and curative responses to adoptive T-cell therapy: T-cell exhaustion and lack of durable stemness, which includes the ability to proliferate, persist and self-renew, as well as generate differentiated effector cell progenies to provide durable anti-tumor functionality. Lyell is applying its proprietary ex vivo genetic and epigenetic reprogramming technology platforms, Gen-R and Epi-R, to address these barriers in order to develop new medicines with improved, durable and potentially curative clinical outcomes. Lyell is based in South San Francisco, California and Seattle and Bothell, Washington. To learn more, please visit www.lyell.com.

Non-GAAP Financial Measures

To supplement our financial results and guidance presented in accordance with U.S. generally accepted accounting principles (GAAP), we present non-GAAP net loss, non-GAAP R&D expenses and non-GAAP G&A expenses. Non-GAAP net loss and non-GAAP R&D expenses exclude non-cash stock-based compensation expense and non-cash expenses related to the change in the estimated fair value of success payment liabilities from GAAP net loss and GAAP R&D expenses, respectively. Non-GAAP net loss further adjusts for the income tax effect, if any, of the non-GAAP adjustments. Non-GAAP G&A expenses exclude non-cash stock-based compensation expense from GAAP G&A expenses. We believe that these non-GAAP financial measures, when considered together with our financial information prepared in accordance with GAAP, can enhance investors’ and analysts’ ability to meaningfully compare our results from period to period, and to identify operating trends in our business. We have excluded stock-based compensation expense and non-cash expenses related to the change in the estimated fair value of success payment liabilities from our non-GAAP financial measures because they are non-cash expenses that may vary significantly from period to period as a result of changes not directly or immediately related to the operational performance for the periods presented. We also regularly use these non-GAAP financial measures internally to understand, manage and evaluate our business and to make operating decisions. These non-GAAP financial measures are in addition to, and not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP. In addition, these non-GAAP financial measures have no standardized meaning prescribed by GAAP and are not prepared under any comprehensive set of accounting rules or principles and, therefore, have limits in their usefulness to investors. We encourage investors to carefully consider our results under GAAP, as well as our supplemental non-GAAP financial information, to more fully understand our business.
