About Us

We are pioneering novel T-cell reprogramming technologies designed to address major barriers to successful adoptive cell therapy (ACT) for solid tumors.

It’s All About the Cells

Using living cells to treat – and sometimes even cure – cancer is one of the most dramatic advances in modern medicine. Patients with hematologic malignancies have been successfully treated with adoptive cell therapies (ACTs). However, these profound results have not yet been achieved in patients with solid tumors, which represent approximately 90% of all cancers. At Lyell, our goal is to change that. We are a fully integrated company developing next-generation T-cell reprogramming technologies to overcome what we believe are the primary barriers to successful ACT in solid tumors: T-cell exhaustion and lack of durable stemness.

Target & Modality Agnostic

Our broad pipeline stems from our technology platforms, which are designed to enhance the three main types of therapy that use engineered immune cells to treat cancer: chimeric antigen receptor (CAR) T-cell therapy; tumor-infiltrating lymphocyte (TIL) therapy; and T-cell receptor therapy (TCR).

Deep Expertise

We were founded by cell therapy pioneers whose decades of research elevated the broader understanding of T-cell biology and its interaction with cancer. The pursuit of scientific excellence and new discoveries continue to drive us forward.

Key Capabilities

Research & Development

We built our paperless, cGMP-qualified LyFE Manufacturing Center in Bothell, Washington to produce cell products at scale. Our in-house infrastructure gives us the ability to control the quality and supply of our products, and quickly adopt and incorporate new technologies.

Information Sciences & Digital Manufacturing
