WALTHAM, Mass.--()--Deciphera Pharmaceuticals, Inc. (NASDAQ:DCPH), a clinical-stage biopharmaceutical company focused on addressing key mechanisms of tumor drug resistance, today announced that two abstracts highlighting DCC-2618, the Company’s KIT and PDGFRα inhibitor have been selected for presentation at the 2018 American Association for Cancer Research (AACR) Annual Meeting, taking place April 14-18, 2018 in Chicago, IL.

Details of the presentations on DCC-2618 are as follows:

Poster Title: Pharmacokinetic (PK), Safety and Tolerability Profile of DCC-2618 in a Phase 1 Trial Supports 150mg QD Selected for a Pivotal Phase 3 Trial
Author: Filip Janku, M.D., Ph.D.
Session: Phase I Clinical Trials 1
Abstract #: CT029
Date & Time: Sunday Apr 15, 2018 1:00 PM - 5:00 PM CT
Location: McCormick Place South, Hall A, Poster Section 42, poster board # 22

Poster Title: Inhibition of Oncogenic and Drug-resistant PDGFRα and KIT Alterations by DCC-2618
Author: Bryan D. Smith
Session: Resistance and Biology
Abstract #: 3925
Date & Time: Tuesday, April 17, 2018 8:00 AM – 12:00 PM CT

“We are pleased to present these data demonstrating potent inhibition of KIT and PDGFRα alterations and mutations with DCC-2618 at the upcoming AACR annual meeting,” said Michael D. Taylor, Ph.D., President and Chief Executive Officer of Deciphera. “Importantly, these results support the growing body of clinical data reported with DCC-2618 in solid tumors and the selection of 150mg once daily as the dose for the recently initiated pivotal Phase 3 trial of DCC-2618 in gastrointestinal stromal tumors (GIST).”

About DCC-2618

DCC-2618 is a KIT and PDGFRα kinase switch control inhibitor in clinical development for the treatment of KIT and/or PDGFRα-driven cancers, including gastrointestinal stromal tumors, glioblastoma multiforme and systemic mastocytosis. DCC-2618 was specifically designed to improve the treatment of GIST patients by inhibiting a broad spectrum of mutations in KIT and PDGFRα. DCC-2618 is a KIT and PDGFRα inhibitor that blocks initiating KIT mutations in exons 9, 11, 13, 14, 17, and 18, known to be present in GIST patients and the D816V exon 17 mutation known to be present in ASM patients. DCC-2618 inhibits PDGFRα mutations in exon 18, including the D842V mutation that drives a subset of GIST.

About Deciphera Pharmaceuticals

Deciphera Pharmaceuticals is a clinical-stage biopharmaceutical company focused on improving the lives of cancer patients by tackling key mechanisms of drug resistance that limit the rate and/or durability of response to existing cancer therapies. Our small molecule drug 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, such as macrophages. We have used our platform to develop a diverse pipeline of tumor-targeted and immuno-targeted drug candidates designed to improve outcomes for patients with cancer by improving the quality, rate and/or durability of their responses to treatment.
