Cell therapy is a significant facet of Sana’s research focus. The company is developing therapies that leverage engineered cells to serve as living medicines capable of providing durable and potent therapeutic effects:

Allogeneic CAR T Cell Therapy: Sana’s cell therapy portfolio includes the development of allogeneic (donor-derived) CAR T cell therapies. Unlike autologous therapies—which require harvesting and engineering a patient’s own cells—allogeneic therapies can be manufactured at scale from a universal donor. Sana’s innovative approach involves engineering these cells with hypoimmune modifications, enabling them to evade both innate and adaptive immune responses. This strategy could result in off-the-shelf therapies that are more accessible and reduce manufacturing delays.

Hypoimmune (HIP) Platform: Central to their cell therapy strategy is the HIP platform. This technology involves modifying the surface proteins of cells to reduce immune detection without compromising cell functionality. In non-human primate models and preclinical studies, HIP-modified cells have demonstrated the ability to survive and function even without immunosuppression—a breakthrough that could have far-reaching implications for a range of cell transplantation therapies.

Stem Cell-Derived Therapeutics: Beyond T cell therapies, Sana is also exploring the use of pluripotent stem cells that can be differentiated into multiple cell types. For instance, the company is investing in stem-cell derived pancreatic islet cells as a potential therapy for type 1 diabetes. These cells, engineered with hypoimmune modifications, are designed to evade immune-mediated rejection upon transplantation.

Broad Indications: The spectrum of diseases targeted by Sana’s cell therapies spans from oncology—where engineered CAR T cells can target cancer cells—to autoimmune diseases and genetic disorders. Each therapeutic candidate is optimized not only for efficacy but also for enhanced safety, manufacturability, and cost-effectiveness.
