Bold ideas. Reliable data. World-Class Science.

Designing therapies to cure our most important health challenges requires the audacity to advance a bold idea and explore new biologies with world-class science.

By pushing at the frontiers of science, challenging what we think we know, and holding ourselves to the highest standards of irrefutable proof, we are reshaping the future of curative cellular therapies.

    ArsenalBio was formed by its investors and scientific founders to discover, develop and commercialize curative and safe cellular therapies for patients with life threatening diseases, initially cancer.

    We believe the most productive and secure route to achieving this goal is to build scaled platforms of technologies challenged with scientific questions to yield informative data from hypothesis driven, well controlled experiments. These data will inform the design of ambitious, best-in-class, lead compositions. Our leads will be rigorously evaluated and honed until we are convinced our matured leads, called development candidates, can be prepared for testing in needy, and vulnerable patients.

    Our products will be designed to speed the transition of cell therapy from hospital-based to outpatient treatments, increasing access to more patients at lower cost to patients, health systems, and insurers.

    To achieve this mission, we are building diverse teams of talented, curious, and caring individuals who believe in our mission and our vision to be sustainable in our business plan, our work habits, and our personal lives.

    Our values create: a foundation for mutual respect, an engaging harmony from many voices, and unselfish behavior to aid our colleagues.
