Senti Bio Announces Multiple Data Presentations at the American Society of Gene and Cell Therapy 2023 Annual Meeting

May 2, 2023

- Four abstracts accepted show the potential of applying gene circuits in multiple cell and gene therapy modalities for neurology, ophthalmology, and oncology -

- New preclinical data demonstrate ongoing progress from collaborations with BlueRock and Spark -

SOUTH SAN FRANCISCO, Calif., May 02, 2023 (GLOBE NEWSWIRE) -- Senti Biosciences, Inc. (Nasdaq: SNTI) (“Senti Bio”), a biotechnology company innovating next-generation cell and gene therapies using its proprietary Gene Circuit platform, today announced two oral presentations and two poster presentations at the American Society of Gene and Cell Therapy (ASGCT) Annual Meeting, being held May 16-20, 2023, in Los Angeles, CA.

“The abstracts accepted for presentation at ASGCT illustrate the potential and modularity of Senti’s gene circuit platform,” said Timothy Lu, MD, PhD, Chief Executive Officer and Co-Founder of Senti Bio. “Our presence at such an important venue this year represents tremendous progress in our wholly-owned and partnered programs, and underlines the incredible work from our research team. The work that will be presented validates the applicability of Senti's technology in modifying a wide range of cells, including NK cells, T cells, AAVs and stem cells, using both viral and non-viral techniques, for a variety of indications including neurology and ophthalmology.”

About Senti Bio
Our mission is to create a new generation of smarter medicines that outmaneuver complex diseases using novel and unprecedented approaches. To accomplish this, we are building a synthetic biology platform that may enable us to program next-generation cell and gene therapies with what we refer to as Gene Circuits. These novel and proprietary Gene Circuits are designed to reprogram cells with biological logic to sense inputs, compute decisions and respond to their cellular environments. We aim to design Gene Circuits to improve the intelligence of cell and gene therapies in order to enhance their therapeutic effectiveness, precision, and durability against a broad range of diseases that conventional medicines do not readily address.

Our synthetic biology platform utilizes off-the-shelf chimeric antigen receptor natural killer (CAR-NK) cells, outfitted with Gene Circuit technologies, to target particularly challenging liquid and solid tumor oncology indications. Our lead product candidate is SENTI-202 for the treatment of CD33 and/or FLT3 expressing hematologic malignancies, such as acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Additionally, our SENTI-401 program is being designed for the treatment of colorectal cancer (CRC) and other CEA-positive cancers. We have also demonstrated in preclinical studies the potential breadth of our Gene Circuits in other modalities, including T cells, adeno-associated viruses (AAVs) and induced pluripotent stem cells (iPSCs), and diseases outside of oncology; and we have executed partnerships with Spark Therapeutics and BlueRock Therapeutics to advance these capabilities.
