Deciphera Pharmaceuticals, Inc. (NASDAQ: DCPH), a biopharmaceutical company focused on discovering, developing, and commercializing important new medicines to improve the lives of people with cancer, today announced the presentation of eight posters at the upcoming AACR Annual Meeting 2023, taking place in Orlando, Florida on April 14-19, 2023. The Company will also host a virtual investor event on Tuesday, April 18 at 6:30 PM ET.

“We are excited to share new preclinical data that demonstrate the breadth and depth of our research capabilities based on our proprietary switch-control kinase inhibitor platform and its ability to generate new opportunities for potential first- and best-in-class kinase inhibitors,” said Steve Hoerter, President and Chief Executive Officer of Deciphera. “At the upcoming AACR meeting, we look forward to presenting preclinical data supporting our next Investigational New Drug (IND) candidate, DCC-3084, a potential best-in-class pan-RAF inhibitor that broadly inhibits Class I, II, and III BRAF mutations, BRAF fusions, and BRAF/CRAF heterodimers. In addition, we will present preclinical data on our ULK inhibitor, DCC-3116, in combination with QINLOCK in gastrointestinal stromal tumor (GIST) and in combination with encorafenib and cetuximab in colorectal cancer that strongly support two new dose escalation combination studies that we expect to initiate in the second half of this year.”

Mr. Hoerter continued, “We continue to expand our leadership position in GIST with the addition of our newest development candidate, DCC-3009, a potential best-in-class pan-KIT inhibitor, which preclinically has demonstrated its ability to potently and very selectively inhibit the broad spectrum of known primary and secondary drug-resistant mutations in GIST, spanning KIT exons 9, 11, 13, 14, 17, and 18. Finally, we are excited to share initial preclinical data on two new programs, GCN2 and PERK, two novel targets focused on the integrated stress response, which is a major adaptive stress response pathway in cancer.”

Copies of the abstracts are available on AACR’s website. Presentation details are as follows:
