Rubius Therapeutics Announces Process to Explore Strategic Alternatives and Leadership Changes

Dannielle Appelhans to Become President and Chief Executive Officer

Pablo J. Cagnoni, M.D., Appointed Chair of the Board of Directors

CAMBRIDGE, Mass., Nov. 02, 2022 (GLOBE NEWSWIRE) — Rubius Therapeutics, Inc. (Nasdaq: RUBY), a biopharmaceutical company that is developing an entirely new class of cellular medicines called Red Cell Therapeutics™ for the treatment of cancer and autoimmune diseases, today announced that it has initiated a process to explore a range of strategic alternatives to maximize shareholder value and plans to engage an investment bank to act as a strategic advisor for this process. Strategic alternatives that will be evaluated include the sale of all or part of the Company or a merger. As a result of this process, Rubius is reducing its workforce by 84% and will retain certain employees to execute the process. The Company also announced the appointment of Dannielle Appelhans as president and chief executive officer, effective November 15, 2022. Ms. Appelhans previously served as chief operating officer since joining Rubius in 2021. Current president and chief executive officer, Pablo J. Cagnoni, M.D., was appointed Chair of the Rubius board of directors, effective immediately, and will continue as president and chief executive officer until November 15, 2022.

Rubius has recently generated new non-human primate data with the next generation cell conjugation RED PLATFORM, demonstrating longer circulation time than observed with the first generation platform and pronounced pharmacodynamic effects as shown by increased levels of interferon gamma, a cytokine critical to both innate and adaptive immunity. In parallel, the Company has advanced a next generation Red Cell Therapeutic, RTX-250, an antigen-specific therapy that is designed to activate dendritic cells.

With the first generation Red Cell Therapeutics, Rubius demonstrated that engineered red blood cells could be manufactured at scale, safely administered and activate a patient’s immune system, resulting in clinical benefit in certain cancer patients, including evidence of tumor shrinkage and prolonged stable disease in PD-(L)-1 refractory solid tumors.

Additional leadership changes include the departures of Pepe Carmona, chief financial officer, and Maiken Keson-Brookes, chief legal officer and corporate secretary. Additional information on the leadership and board changes, and the Company’s plan for strategic alternatives, can be found in Rubius’ current report on Form 8-K being filed with the U.S. Securities and Exchange Commission on or about the date hereof.
