Unum Therapeutics Announces US Patent Protection for ACTR Technology

• US Patent and Trademark Office Issues US Patent 10,144,770 Covering Antibody-Coupled T-cell Receptors (ACTR)
  
  
• Broad Claims Provide Composition of Matter Protection for Cell Therapies and Their Methods of Use
  
  
• Unum Controls Exclusive World-Wide Patent Rights for ACTR Therapies

CAMBRIDGE, Mass., Dec. 06, 2018 (GLOBE NEWSWIRE) -- Unum Therapeutics Inc. (NASDAQ: UMRX), announced today that the United States Patent and Trademark Office has issued US patent 10,144,770, entitled “Chimeric Receptors and Uses Thereof in Immune Therapy.” The ‘770 patent covers design and use of the chimeric Antibody-Coupled T-cell Receptor (ACTR) platform technology that enables an engineered immune cell to be targeted via an antibody to attack certain cell types, including cancer cells. An ACTR-expressing T cell offers a number of potential advantages over alternative cell therapy approaches and clinical proof-of-concept for the ACTR technology has been demonstrated in two independent clinical trials sponsored by Unum Therapeutics. ACTR therapeutic programs targeting non-Hodgkin lymphoma, multiple myeloma, and HER2+ advanced cancers are currently in early stages of clinical testing.

The initial ACTR construct was developed by Dr. Dario Campana, a well-renowned cancer researcher recognized as an inventor of the chimeric antigen receptor that forms the basis for tisagenlecleucel, the world’s first approved CAR-T therapy. Working initially at St. Jude Children’s Research Hospital and later at the National University of Singapore, Dr. Campana and his team were able to demonstrate in mouse studies that ACTR-expressing T cells exhibit potent anti-tumor activity. Researchers at Unum Therapeutics extended upon this work, demonstrating that a wide range of functional ACTR receptors could be constructed using different building blocks derived from various human immune cell receptors.

Under the terms of a 2014 three-way license agreement between Unum Therapeutics, the National University of Singapore, and St. Jude Children’s Research Hospital, Unum Therapeutics controls exclusive, world-wide rights to develop and commercialize ACTR therapies covered by the ‘770 patent. Unum has continued to build a broad patent portfolio encompassing further enhancements to and novel applications of the ACTR technology. In addition to the ‘770 patent covering ACTR in the United States, previously granted patents protect the technology in Europe, Japan, and other important territories. The full text of the ‘770 patent is available from the US Patent and Trademark Office website at .
