WALTHAM, Mass.--(BUSINESS WIRE)--Jan. 11, 2021-- Deciphera Pharmaceuticals, Inc. (NASDAQ:DCPH), a commercial-stage biopharmaceutical company developing innovative medicines to improve the lives of people with cancer, today provided a corporate update and highlighted key 2021 milestones in conjunction with its presentation at the 39th Annual J.P.
