Sana’s ambition is to repair or replace any cell in the body. Technologies address fundamental barriers: Hypoimmune (HIP) technology: Overcoming immune rejection of allogeneic cells  Fusogen technology: In vivo delivery of genomic modification reagents in a cell-specific manner Overcoming immune rejection of allogeneic cells has potential to change cell therapy: Allogeneic CAR T cells that perform clinically like autologous CAR T cells can transform treatment of hematological malignancies Key to unlocking the potential of stem cell-derived therapies such as pancreatic islet cells for the treatment of type 1 diabetes Three programs in the clinic... SC291 in oncology: Goal of understanding immune evasion and activity in multiple cancers SC291 in autoimmune diseases: Goal of understanding activity in three indications  HIP primary islets in patients with type 1 diabetes: Goal of understanding ability to overcome allogeneic and autoimmune destruction of cells ...and more to come. Pipeline poised to deliver multiple clinical data readouts  Hypoimmune allogeneic CAR T cells: SC262 (CD22), SC255 (BCMA), and beyond Regenerative medicine: SC451 (type 1 diabetes) and SC379 (CNS disorders) Balance sheet allows potential for multiple data readouts Engineered Cells as Medicines Sana Biotechnology
