Data Selected for Oral Presentation from Late-Breaking Abstract from NIH-Partnered Study Showing Engraftment without Preconditioning in Non-Human Primates
Engineered B Cells Demonstrate In Vivo Anti-Tumor Efficacy with Bi-specific T Cell Engagers
Additional Studies Demonstrate Precise Engineering and Expression of Multiple Therapeutic Proteins
CAMBRIDGE, Mass. May 2, 2023 – Be Biopharma, Inc. (“Be Bio”), a company pioneering the discovery and development of Engineered B Cell Medicines (BeCMs), announced that it will present new data from preclinical research and collaboration programs at the American Society of Gene & Cell Therapy (ASGCT) 26th Annual Meeting taking place May 16-20, 2023, in Los Angeles, Calif.
A late-breaking abstract was selected for oral presentation from Be Bio’s collaboration study with the National Heart, Lung, and Blood Institute, National Institutes of Health in which homing and engraftment of plasma cells were observed from peripheral B cells without preconditioning in immune competent non-human primates. In a separate oral presentation, the precise engineering of B cells using Be Bio’s proprietary engineering platform will be featured. Additionally, a poster presentation will show the stable expression and continuous secretion of therapeutic proteins in vitro and in vivo. Finally, Be Bio’s scientific co-founders and collaborators from the Seattle Children’s Research Institute will present findings in which engineered B cells produced Bi-specific T cell engagers that mediated T cell activation and showed in vivo anti-tumor efficacy in a patient-derived xenograft model.
“Data from our preclinical research programs support the ability of Be Bio’s platform to unlock the power of B cells as the basis for a prolific and versatile product engine,” said Dr. Rick Morgan, Chief Scientific Officer, Be Bio. “We are inspired by the potential to transform patient lives with B cell medicines as we progress our lead candidate towards an investigational new drug application and advance our novel pipeline programs in rare disease and oncology.”

About B Cells – A New Class of Cellular Medicines
Imagine what could “Be?” In nature, a single B cell engrafts in the bone marrow and can produce thousands of proteins per second at constant levels over decades. B cells are nature’s exquisite medicine factories, manufacturing proteins to fight disease and maintain health. Unleashing the power of B cells is driving a new class of cellular medicines – Engineered B Cell Medicines (BeCMs). BeCMs have the potential to be durable, allogeneic, redosable and administered without toxic conditioning. The promise of BeCMs could transform therapeutic biologics with broad application — across protein classes, patient populations and therapeutic areas.
