Abintus Bio, Inc.

Driven by a bold founding vision: Empowering patients from within, Abintus is pioneering potentially curative, off-the-shelf genetic medicines that engineer cells directly inside the patient’s body, also termed in vivo. These therapies are based on Abintus' clinically proven Modular Delivery Platform (MDP). The company’s two initial, fit-for-purpose, In Vivo programs are: 1. Highly selective gene expression targeting cell type/state via synthetic biology (e.g., In Vivo CAR-NK/T/Treg, In Vivo TCR-T) with applications across multiple gene delivery systems (e.g., AAV, lenti, adeno, retro) and therapeutic areas including leukemia, solid tumors, autoimmune, infectious, and genetic disease. 2. Simultaneous engineering of a diverse repertoire of active innate and adaptive immune cells (e.g., In Vivo CAR-X) with applications in diseases such as lymphoma and solid tumors. Abintus is leveraging over 20 years and $275 million of prior technology advancement for in vivo engineering including the treatment of over 350 patients through Phase 3 registration trials. Our company name comes from the Latin words “ab intus”, which means “from within”. We chose this name for 3 reasons: 1) Patients: We are pursuing product candidates that are designed to directly empower patients’ own immune cells to fight their disease from within. 2) Science: Our team is committed to scientific excellence and continual learning. Our differentiated technologies have the potential to directly reprogram activated immune cells “in situ”, or from within. 3) Culture: We believe our ability to achieve our vision will come from within - by building a performance-driven culture that prioritizes career development and rewards outstanding contributions. Abintus’ initial funding syndicate included Takeda Ventures and The Leukemia & Lymphoma Society’s Therapy Acceleration Program® (LLS TAP). Abintus Bio, Inc. (“Abintus”) is headquartered in San Diego. www.abintusbio.com.
