Lyell Immunopharma, based in South San Francisco, CA, is a pioneering biotech startup focused on revolutionizing cancer treatment. The company specializes in developing advanced cell therapies to treat solid tumors, which are masses of tissue that can be cancerous. Their primary technology involves mastering T cells, a type of immune cell, to effectively target and destroy cancer cells.

Lyell serves patients suffering from solid tumors, aiming to provide curative treatments where traditional methods have failed. The company operates in the highly specialized oncology market, which deals with the study and treatment of cancer. Their business model revolves around scientific innovation and the development of a diverse product pipeline. This pipeline includes multiple treatment modalities, meaning they are exploring various methods to treat different types of solid tumors.

The company makes money by developing proprietary technologies and therapies that can be licensed to other pharmaceutical companies or sold directly to healthcare providers. Their key technologies, Gen-R and Epi-R, involve genetic and epigenetic reprogramming. In simpler terms, they modify the genes and the way genes are expressed in T cells to overcome two major challenges: T cell exhaustion (when T cells lose their ability to fight cancer) and lack of durable stemness (the ability of T cells to renew themselves and persist in the body).

Lyell's commitment to scientific innovation is evident in their world-class team, which includes leading experts in oncology and adoptive cell therapy (ACT). Their goal is to create curative cell therapies for any solid tumor, pushing the boundaries of current cancer treatment options.
