Sana Biotechnology, Inc., a firm focused on producing and delivering engineered cells as medicines, recently announced that the FDA has approved the company's Investigational New Drug (IND) application to begin a first-in-human trial of SC291 in patients with different types of B-cell malignancies.
SC291 is an allogeneic CAR T cell therapy that targets CD19. It is developed by Sana using its hypoimmune platform. The hypoimmune platform's objective is to overcome the allogeneic cells' immunologic rejection, which, if valid for SC291, could lead to prolonged CAR T cell persistence and increased rates of durable complete responses in patients with B-cell lymphomas or leukemias.
The hypoimmune platform includes disruption of the major histocompatibility (MHC) class I and class II expression to conceal cells from the adaptive immune system, which consists of antibody and T cell responses and overexpression of CD47 to inhibit activation of the innate immune cell system, especially macrophages and natural killer (NK) cells. The company has provided evidence from numerous preclinical models demonstrating the potential of this platform to cloak cells from immune detection and the therapeutic potential of SC291 for patients with B-cell malignancies.
About Sana Biotechnology
Founded in 2018, Sana Biotechnology is a firm focused on utilizing engineered cells as medicines for patients. It is constructing differentiated capabilities across the spectrum of cell and gene therapy. The company is motivated by three goals as it seeks solutions for people with poor outcomes or diseases that are currently incurable. The first is the ability to repair and control the genes in any cell in the body. It is developing innovative delivery technologies in order to deliver any payload to any cell in a precise, predictable, and repeatable manner, paving the way for next-generation in vivo gene therapy. Next comes the ability to develop pluripotent stem cells ex vivo into immune-cloaked functional cells, to replace any missing or damaged cells in the body. Finally, it believes that it can also enable broader access to its therapies by focusing on scalable manufacturing solutions, the manufacturing costs, and aligning with key stakeholders.
