Concert Pharmaceuticals Announces Patent Trial and Appeal Board Did Not Institute PGR Proceeding

LEXINGTON, Mass.--(BUSINESS WIRE)-- Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today announced that the Patent Trial and Appeal Board (PTAB) of the U.S. Patent and Trademark Office has decided not to grant the Company's Post Grant Review (PGR) petition challenging the validity of U.S. Patent No. 9,662,335 (referred to as the '335 patent) assigned to Incyte Pharmaceuticals.

"We are disappointed that the PTAB has denied our petition on the '335 patent. This decision does not prohibit us from challenging the validity of the patent at a later time in federal court, and we will continue with our plans to develop CTP-543 for alopecia areata. We don't expect any disruption to our clinical timelines," said Roger Tung, President and CEO of Concert Pharmaceuticals. "We remain committed to developing the first FDA-approved treatment for alopecia areata; however, we are reassessing whether to expand CTP-543 into additional indications."

In July 2017, Concert filed a PGR petition challenging the validity of Incyte's '335 patent covering deuterated ruxolitinib analogs. Documents relating to the PGR can be accessed online at: http://www.concertpharma.com/technology-overview/intellectual-property/.
