Rubius Therapeutics
 Cambridge, MA
Rubius Therapeutics is a rapidly-growing, clinical-stage biopharmaceutical company that is genetically engineering red blood cells into an entirely new class of allogeneic, off-the-shelf cellular medicines.  Our Red Cell Therapeutics™ (RCTs) can potentially be used to replace missing enzymes for patients living with rare enzyme deficiencies, kill tumors in cancer and regulate the immune system for the treatment of autoimmune diseases.  Our first RCT™ product candidate is RTX-134 for the potential treatment of phenylketonuria, a rare metabolic disorder.  We expect to report initial clinical data by the end of 2019 from our Phase 1 clinical trial.  Additionally, we plan to file our first oncology Investigational New Drug (IND) application for RTX-240 for the treatment of solid tumors by early 2020.  In total, we plan to file four to five INDs during 2019 and 2020.

We are proud of our passionate, high-performance culture – one based on a set of values that are the cornerstone of who we are and how we hold ourselves accountable. Founded in 2013, we are based in Cambridge, MA and currently expanding across all functions within the organization.  Having completed our initial public offering in July 2018, (Nasdaq:RUBY), we are well capitalized to execute our vision of creating life-changing cellular medicines. Red blood cells are no longer just for carrying oxygen.  At Rubius, we are transforming them into medicines.  Check us out at or follow us on Twitter and LinkedIn.
