LYEL Lyell Immunopharma Inc

Cellares, the first Integrated Development and Manufacturing Organization (IDMO) dedicated to clinical and industrial-scale cell therapy manufacturing, and Lyell Immunopharma (NASDAQ: LYEL), a clinical‑stage T-cell reprogramming company advancing a diverse pipeline of cell therapies for patients with solid tumors, today announced Lyell will evaluate Cellares’ automated manufacturing platform, the Cell Shuttle™, through Cellares’ Technology Adoption Partnership (TAP) program. As part of the collaboration, the companies have agreed on a proof-of-concept technology transfer process for the manufacture of Lyell’s LYL797 CAR T-cell therapy, using the Cell Shuttle.

CAR T-cell therapy is a personalized immunotherapy that takes a patient’s own T cells and modifies them to recognize and kill cancer cells that have a specific biomarker. LYL797 is an investigational CAR T-cell therapy in development for the treatment of solid tumors that express ROR1, a protein present on the surface of various solid tumors. LYL797 is enhanced with Lyell’s novel genetic and epigenetic reprogramming technologies designed to generate highly tumor-reactive, longer-lasting functional T cells. Lyell is enrolling patients with triple-negative breast cancer and non-small cell lung cancer in a Phase 1 clinical trial evaluating LYL797.

“We are excited to work with Cellares to evaluate their innovative automated manufacturing processes as part of our overall manufacturing strategy to efficiently, rapidly, and cost-effectively scale manufacturing capacity for our CAR T-cell product candidates for future clinical trials and potential commercialization,” said Stephen Hill, Chief Operating Officer of Lyell. “We are impressed with the progress Cellares has made with their manufacturing capabilities, and the commitment and vision of the Cellares team to apply these technologies to help deliver new and potentially transformative therapies to patients.”

Cellares' TAP program offers cell therapy developers a swift and low-risk pathway to embrace the company's automated manufacturing technology for their pipeline products. Lyell is utilizing this program to assess the automated manufacturing process and generate data that validates the Cell Shuttle's viability as a manufacturing option for CAR T-cell therapies. Cellares partners with prominent cell therapy developers through its TAP program to integrate the Cell Shuttle as a GMP manufacturing solution in both clinical and commercial stages at their IDMO Smart Factories.

"By integrating LYL797 into our TAP program, we seek to demonstrate the ability to seamlessly adapt Lyell’s CAR T-cell manufacturing process to our Cell Shuttle platform," said Fabian Gerlinghaus, CEO of Cellares. "This collaboration represents a significant step towards fulfilling our vision of accelerating access to life-saving cell therapies, reducing process failure rates, and meeting total patient demand through the efficient utilization of the Cell Shuttle platform at global scale."

Cellares' innovative manufacturing technology transforms autologous and allogeneic cell therapy processes, covering nearly 90% of cell therapy modalities. Through their TAP program, Cellares can facilitate the automation and tech transfer of manual processes onto the Cell Shuttle manufacturing platform in just six months. This program allows cell therapy developers to seamlessly integrate their processes onto a Cell Shuttle at any stage of development - from pre-clinical to post-regulatory approval. With automation, standardization, and software-defined manufacturing (SDM), subsequent tech transfers become instant to any other Cell Shuttle into any IDMO Smart Factory worldwide.

About Lyell Immunopharma, Inc.Lyell is a clinical-stage T-cell reprogramming company advancing a diverse pipeline of cell therapies for patients with solid tumors. Lyell is currently enrolling a Phase 1 clinical trial evaluating a ROR1-targeted CAR T-cell therapy in patients with relapsed refractory triple-negative breast cancer and non-small cell lung cancer (NSCLC) and a second Phase 1 clinical trial evaluating reprogrammed tumor infiltrating lymphocytes (TIL) in patients with advanced melanoma, NSCLC and colorectal cancer. The technologies powering its product candidates are 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 is applying its proprietary ex vivo genetic and epigenetic reprogramming technologies to address these barriers in order 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.
