WALTHAM, Mass.--(BUSINESS WIRE)--Jan. 13, 2020-- Deciphera Pharmaceuticals, Inc. (NASDAQ:DCPH) today provided a corporate update and highlighted key 2020 milestones in conjunction with its presentation at the 38th Annual J.P. Morgan Healthcare Conference in San Francisco. The Company will webcast its presentation today at 11:00 a.m. PT (2:00 p.m. ET) at https://investors.deciphera.com/news-events/events-presentations.

"2019 was a year of many exciting accomplishments for Deciphera as we submitted our first New Drug Application (NDA) to the FDA for ripretinib in advanced gastrointestinal stromal tumors (GIST) based on positive results from the INVICTUS pivotal Phase 3 study and advanced our portfolio of wholly-owned product candidates,” said Steve Hoerter, President and Chief Executive Officer of Deciphera. “We are preparing for a potential commercial launch in the U.S. and working to bring ripretinib to other parts of the world.”

The Company announced today that two additional marketing applications have been submitted for ripretinib as part of the U.S. Food and Drug Administration’s (FDA) Project Orbis pilot program. The marketing applications of ripretinib for advanced GIST in Canada and Australia have both received priority review designations. The Project Orbis pilot program, an initiative of the FDA Oncology Center of Excellence, is designed to provide a framework for concurrent submission and review of oncology products among international partners. Additional information about Project Orbis can be found at: https://www.fda.gov/about-fda/oncology-center-excellence/project-orbis.

Mr. Hoerter continued, “In parallel with these efforts, we have laid the groundwork for further expansion across our pipeline of novel agents. We continued to activate sites and enroll patients in the INTRIGUE Phase 3 study in the 2nd line GIST patient population, advanced the DCC-3014 and rebastinib clinical development programs, and added a new internally-discovered candidate, DCC-3116, to our pipeline. We look forward to building on our momentum in 2020 as we work with the FDA towards a potential approval of ripretinib in advanced GIST and rapidly advance our additional programs.”

In 2020, the Company seeks to achieve the following milestones:

Ripretinib
- Potential FDA approval and commercial launch of ripretinib in advanced GIST.
- Submit marketing authorization application to European Medicines Agency.
- Complete enrollment of INTRIGUE Phase 3 study in 2nd line GIST.
- Present Phase 1 study expansion data.

DCC- 3014
- Select Phase 2 dose for tenosynovial giant cell tumor (TGCT) patients and open expansion cohort.
- Provide update on Phase 1 data in TGCT patients.

About Deciphera Pharmaceuticals

Deciphera Pharmaceuticals is a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients by addressing key mechanisms of drug resistance that limit the rate and/or durability of response to existing cancer therapies. Our small molecule product candidates are directed against an important family of enzymes called kinases, known to be directly involved in the growth and spread of many cancers. We use our deep understanding of kinase biology together with a proprietary chemistry library to purposefully design compounds that maintain kinases in a “switched off” or inactivated conformation. These investigational therapies comprise tumor-targeted agents designed to address therapeutic resistance causing mutations and immuno-targeted agents designed to control the activation of immunokinases that suppress critical immune system regulators, and agents designed to inhibit reprogramming of cancer cell metabolism. We have used our platform to develop a diverse pipeline of tumor-targeted, immuno-targeted, and metabolism-targeted product candidates designed to improve outcomes for patients with cancer by improving the quality, rate and/or durability of their responses to treatment.
