Rubius Therapeutics Announces Preclinical Data from Red Cell Therapeutic Oncology Programs to be Presented at the ASGCT 23rd Annual Meeting

April 29, 2020

CAMBRIDGE, Mass., April 29, 2020 (GLOBE NEWSWIRE) -- Rubius Therapeutics, Inc. (Nasdaq:RUBY), a clinical-stage biopharmaceutical company that is genetically engineering red blood cells to create an entirely new class of cellular medicines, today announced that the company will present preclinical data from its oncology pipeline of Red Cell Therapeutics™ (RCTs) at the American Society of Gene and Cell Therapy (ASGCT) 23rd Annual Meeting. The meeting is being held virtually from May 12 – 15, 2020.

“At Rubius Therapeutics, we are engineering Red Cell Therapeutics to replicate how the immune system naturally fights cancer. At the ASGCT Annual Meeting, we plan to present preclinical data from our lead artificial antigen-presenting cell (aAPC) program, RTX-321, for the treatment of HPV 16-positive tumors, demonstrating that we can activate and expand antigen-specific T cells for tumor-specific immunotherapy in vitro. Importantly, we will show that we can expand the different cell populations that are critical for delivering and maintaining long-term, anti-tumor responses. We plan to file an Investigational New Drug application for RTX-321 by the end of 2020,” said Laurence Turka, M.D., chief scientific officer of Rubius Therapeutics. “Additionally, we plan to present data showing that our aAPC platform can expand both naïve and exhausted CD4+ T cells in vitro. This finding is significant because both of these cell types may be present in patients with HPV 16-positive cancers, suggesting that we may be able to harness the full complement of tumor-specific CD4+ T cells to achieve durable responses in patients.”

The abstracts can be accessed via the ASGCT website meeting planner. All posters will be made available at the beginning of the virtual meeting on Tuesday, May 12, 2020, at 6:00 a.m. ET and during the poster presentation sessions:
