Cerus Corporation (Nasdaq: CERS) today announced that the U.S. Patent and Trademark Office has issued a patent to Cerus that significantly expands its patent coverage for methods to inactivate viruses, bacteria and parasites in blood products using compounds that bind to nucleic acid (DNA and RNA). U.S. patent number 6410219 covers the use of a wide category of compounds that target DNA or RNA, as well as the therapeutic use of blood or blood components treated with these methods.
“As we approach commercialization with our partner Baxter Healthcare for the INTERCEPT Blood System, we have built a strong proprietary position that establishes high barriers to entry,” said Stephen T. Isaacs, president and chief executive officer of Cerus Corporation. “This broad new patent is central to the use of nucleic acid binding compounds to inactivate pathogens in red blood cells.”
Cerus' patent portfolio consists of over 60 issued and pending patents covering methods and compositions to inactivate pathogens in blood and blood products using specific compounds that bind with DNA or RNA. The latest patent extends coverage to use of compounds that include chemical structures known as aziridines and aziridiniums.
Cerus and Baxter Healthcare Corporation are collaborating on the development of the INTERCEPT Blood System to enhance the safety of blood transfusions. A CE Mark for the INTERCEPT Platelet System disposable set has been received, and the companies have begun the regulatory submission process to obtain approval in the United States. Separately, the companies are preparing the U.S. regulatory submission for the INTERCEPT Plasma System, which will be followed by a CE Mark application for this product. In addition, the companies are conducting Phase III clinical trials for the INTERCEPT Red Blood Cell System.
