Sana Biotechnology to Present Data from Multiple Preclinical Studies at the American Society of Gene and Cell Therapy 25th Annual Meeting

SEATTLE, May 02, 2022 (GLOBE NEWSWIRE) -- Sana Biotechnology, Inc. (NASDAQ: SANA), a company focused on creating and delivering engineered cells as medicines, today announced that five abstracts covering preclinical data from its hypoimmune and fusogen platforms were accepted for either oral or poster presentation at the American Society of Gene and Cell Therapy (ASGCT) 25^th Annual Meeting taking place May 16-19, 2022 in Washington, D.C.

“We will have a strong presence at ASGCT, with presentations of data from multiple technology platforms, including two oral presentations on our hypoimmune platform and two posters on our fusogen platform,” said Steve Harr, MD, Sana’s President and CEO. “We remain excited with the progress we are making with these platforms that are targeted to address some of the major challenges faced in the field of gene and cell therapy. Our goal is to file two INDs this year from two of these platforms, with the aim of translating our exciting scientific progress into beneficial therapeutics for patients.”

About Hypoimmune Platform
Sana’s hypoimmune platform is designed to create cells ex vivo that can “hide” from the patient’s immune system to enable the transplant of allogeneic cells without the need for immunosuppression. We are applying the hypoimmune technology to both pluripotent stem cells, which can then be differentiated into multiple cell types, and to donor-derived allogeneic T cells, with the goal of making potent and persistent CAR T cells at scale. Preclinical data demonstrates across a variety of cell types that these transplanted allogeneic cells are able to evade both the innate and adaptive arms of the immune system while retaining their activity. Our most advanced programs utilizing this platform include an allogeneic CAR T program targeting CD19+ cancers and stem-cell derived pancreatic cells for patients with type 1 diabetes.

About Fusogen Platform
Sana is developing re-targetable fusogens as a platform technology to enable the in vivo delivery of genetic payloads to specific cell types. Fusogens can bind to cell-surface proteins on the target cell type and, when combined with delivery vehicles to form fusosomes, deliver a genetic payload directly to the cell’s cytoplasm. We have shown in preclinical studies that we can engineer fusogens to specifically target diverse cell surface receptors that allow cell-specific delivery across multiple different cell types. Our most advanced programs utilizing this platform include in vivo CAR T cell fusosome product candidates targeting CD19+ cancer cells, including non-Hodgkin lymphoma, chronic lymphocytic leukemia, and acute lymphocytic leukemia.
