Rubius Therapeutics Announces Issuance of Multiple U.S. Patents for its Red Cell Therapeutic Programs

42 Days ago

First U.S. Composition of Matter Patent Issued for Genetically Engineered Red Cell

CAMBRIDGE, Mass., June 05, 2019 (GLOBE NEWSWIRE) -- Rubius Therapeutics, Inc. (Nasdaq: RUBY), a clinical-stage biopharmaceutical company that is generating red blood cells and bioengineering them into an entirely new class of allogeneic, off-the-shelf cellular medicines, today announced the issuance of three patents from the U.S. Patent and Trademark Office (USPTO) related to its rare disease and oncology programs and platforms. Two of the issued patents cover composition of matter and methods of use for the Company’s lead investigational cellular therapy, RTX-134, for the treatment of patients with phenylketonuria (PKU). The third patent, the Company’s first issued composition of matter patent in immuno-oncology, relates to human cells having a checkpoint inhibitor linked to the cell surface. In total, Rubius Therapeutics has 29 patent families and more than 125 pending patent applications worldwide.

“The issuance of these key patents strengthens our growing intellectual property portfolio and demonstrates our leadership position in the field of cellular therapy,” said Pablo J. Cagnoni, M.D., chief executive officer of Rubius Therapeutics. “The RTX-134 composition of matter and methods of use patents, along with our immuno-oncology patent, highlight the breadth of both our platform and our patent estate. We intend to continue to pursue worldwide patent protection for our  novel  compositions, methods, treatment, dosing, formulations and methods of manufacturing related to our Red Cell Therapeutics.” 

RTX-134 Patent Issuances

Rubius Therapeutics’ lead RCT™ product candidate is RTX-134, an allogeneic, off-the-shelf cellular therapy for the potential treatment of patients with PKU. U.S. Patent No. 10,301,594, the Company’s first composition of matter patent for a RCT, covers genetically-engineered erythroid cells, such as RTX-134, that have the enzyme phenylalanine ammonia lyase (PAL) inside the cell. The new use patent, U.S. Patent No. 10,253,296, covers methods of decreasing phenylalanine using genetically-engineered erythroid cells, such as RTX-134, that have PAL inside the cell. RTX-134 is designed to circulate in the blood stream and degrade toxic levels of phenylalanine that accumulate due to a deficiency in the phenylalanine hydroxylase (PAH) enzyme. Compared to current therapeutic interventions, RTX-134 may have a more sustained treatment effect given the 120-day circulating time of red blood cells and may have a lower incidence of immune-driven adverse events, including the formation of neutralizing antibodies to the therapeutic enzyme, which often results in a reduction in efficacy. As a result, RTX-134 may provide a more efficacious, safe and convenient treatment option for patients. The Company expects to begin enrollment in a Phase 1b clinical study this quarter with initial clinical data anticipated during the second half of 2019.

Immuno-Oncology Patent Issuance

The Company’s first issued immuno-oncology patent, U.S. Patent No. 10,260,038, is a composition of matter patent directed to any human cell onto which any checkpoint inhibitor may be linked via an endogenous sortase recognition sequence. This patent is exclusively licensed from the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology. Rubius Therapeutics’ oncology and immune-oncology estate includes more than 25 patents and patent applications worldwide.
