Coherus BioSciences Completes Patent Dance Exchange with Amgen for Neulasta Biosimilar

Apr 25, 2017

REDWOOD CITY, Calif., April 25, 2017 (GLOBE NEWSWIRE) -- Coherus BioSciences, Inc. (Nasdaq:CHRS), announced today that it completed the initial phases of the Biologics Price Competition and Innovation Act (BPCIA) patent exchange procedure with Amgen for Coherus’ Neulasta (pegfilgrastim) biosimilar candidate, CHS-1701.  Of the two patents originally listed by Amgen in the process, the parties have reached agreement on a single patent for potential litigation, U.S. patent 8,273,707 (the ‘707 patent), directed to a method for purifying the product.   

Under the provisions of the BPCIA patent dance, Amgen is subject to a 30-day deadline, expiring on May 11, 2017, to file a patent infringement suit against Coherus under the ‘707 patent.  Failure to do so will result in Amgen’s loss of injunctive rights under the patent, limiting any potential recovery to monetary damages. Litigation has not yet been initiated.

“We are confident a court will conclude that our CHS-1701 manufacturing process does not infringe the ‘707 patent,” stated Denny Lanfear, President and CEO of Coherus, further adding “aside from its lack of any relevance to our process, there are also serious questions regarding the validity of this patent. We are well prepared for the possibility that Amgen may decide to assert the ‘707 patent against us and will defend any such suit vigorously.”  

Mr. Lanfear continued, “Coherus remains committed to its mission of bringing the highest quality biosimilar drugs to the marketplace. We are confident that we will prevail and achieve our goals of increasing patient access and introducing competition by offering biosimilar products at prices competitive with and lower than those maintained by originator companies, thereby delivering savings that are much-needed for new therapies.”
