"Recent clinical and corporate achievements support Deciphera’s transition to a late-stage, pre-commercial company," said Michael D. Taylor, Ph.D., President and Chief Executive Officer of Deciphera. "Data presented at ESMO (Free ESMO Whitepaper) have bolstered our confidence in DCC-2618’s potential to transform the current treatment paradigm for GIST patients. As we approach the completion of enrollment for our pivotal Phase 3 INVICTUS study in the coming weeks, we look forward to the data readout from that study expected next year. In addition, we remain on track to initiate our Phase 3 INTRIGUE study later this year. We are building our commercial capabilities for DCC-2618 in the United States and are continuing to invest in our clinical-stage pipeline, with the recent initiation of our Phase 1b/2 clinical study of our investigational agent rebastinib in combination with paclitaxel."

Clinical Programs

DCC-2618
At the European Society of Medical Oncology (ESMO) (Free ESMO Whitepaper) 2018 Congress in October 2018, Deciphera presented updated preliminary Phase 1 clinical study results of DCC-2618 in patients with gastrointestinal stromal tumors (GIST). Highlights from the presentation included:
Preliminary median progression free survival (mPFS) in second- and third-line GIST patients of 42 weeks and 40 weeks, respectively, that the Company believes demonstrates the potential for improved and durable clinical outcomes in patients with less advanced disease.
Updated objective response rates (ORR) and disease control rates (DCR) in second- and third-line GIST patients continue to exceed previously published results of registrational trials for currently approved therapies.
In fourth-line and fourth-line-plus GIST patients, for whom there are currently no approved therapies, the Company believes that the observed mPFS of 24 weeks demonstrates the potential for durable clinical outcomes in patients with advanced disease. Published studies have reported a mPFS of 4 to 6 weeks for similarly heavily pre-treated patients who did not receive an active therapy.
Deciphera expanded the ongoing Phase 1 study to include additional cohorts for patients with: various solid tumors, including melanoma; non-small cell lung cancer; germ cell cancer; penile cancer; soft tissue sarcoma; GIST or other solid tumor patients with renal impairment.
Deciphera will present preclinical data on the effects of the combination of DCC-2618 and MAPK pathway inhibitors on cell death and apoptosis in cellular assays of GIST and mastocytosis in a poster session at the EORTC-NCI-AACR (Free EORTC-NCI-AACR Whitepaper) Molecular Targets and Cancer Therapeutics Symposium on November 13, 2018.
Data in GIST patients from the ongoing Phase 1 study that were presented at the ESMO (Free ESMO Whitepaper) 2018 Congress in October 2018 will also be presented at the Annual Meeting of the Connective Tissue Oncology Society (CTOS) on November 15, 2018.
Deciphera previously announced that, following discussions with regulatory authorities in the United States and Europe, it is planning to initiate later this year a randomized, multicenter, open-label, pivotal Phase 3 INTRIGUE study evaluating DCC-2618 compared to sunitinib in second-line GIST patients.
Rebastinib
Deciphera initiated a Phase 1b/2 clinical study of rebastinib, the Company’s small molecule kinase switch control inhibitor of TIE2. In this two-part clinical study, rebastinib will be evaluated for the treatment of patients with advanced or metastatic solid tumors in combination with paclitaxel.
DCC-3014
Deciphera continues to enroll patients in the Phase 1 dose escalation study of DCC-3014, a selective small molecule kinase switch control inhibitor of CSF1R and expects to provide an update on this study later this year.
Corporate Updates

In September 2018, Deciphera appointed Daniel C. Martin as Chief Commercial Officer. Mr. Martin has more than 20 years of commercial experience within the biopharmaceutical industry with extensive background in oncology, including immuno-oncology.
In November 2018, Oliver Rosen, M.D., informed Deciphera that effective November 30, 2018, he would leave his position as the Company’s Chief Medical Officer to pursue another opportunity at an early-stage, private biotechnology company. The Company has commenced a search for his replacement.
"On behalf of the management team and board of directors, I want to thank Oliver for his many contributions to Deciphera over the past four and a half years," said Dr. Taylor. "During his tenure, Oliver was instrumental in developing DCC-2618 from a promising preclinical asset into a robust late-stage clinical program with a pivotal Phase 3 study expected to read out in 2019, a second Phase 3 study that is planned to initiate soon and a series of expansion studies in multiple indications. We wish Oliver all the best in his future endeavors."

"It has been a privilege to be a part of Deciphera’s successful growth since 2014 led by the rapid development of DCC-2618," said Dr. Rosen. "I am proud of the progress the Company has made in translating the promise of its kinase switch control platform into an exciting pipeline of clinical-stage drug candidates designed to provide cancer patients with novel therapies that address unmet medical needs."

Third Quarter 2018 Financial Results

Cash Position: As of September 30, 2018, cash and cash equivalents were $320.9 million, compared to cash and cash equivalents of $196.8 million as of December 31, 2017. This increase was primarily related to proceeds obtained through the Company’s June 2018 underwritten public offering, offset by cash used in operating activities. We expect our current cash and cash equivalents will enable us to fund our operating and capital expenditures and debt service payments into the second half of 2020.
R&D Expenses: Research and development expenses for the third quarter of 2018 were $20.6 million, compared to $9.8 million for the same period in 2017. The increase was primarily due to an increase in spending on the DCC-2618 program of $6.1 million as a result of clinical trial costs related to the pivotal Phase 3 INVICTUS study that began enrollment in January 2018. Clinical trial costs also increased due to start-up activities related to a second Phase 3 INTRIGUE study in second-line GIST, which is expected to be initiated by the end of 2018. In addition, chemistry, manufacturing and controls development and manufacturing costs for the DCC-2618 program increased as a result of process development activities to support anticipated drug requirements for commercialization and the manufacture of registration lots to support the submission of a new drug application. Expenses related to the rebastinib program increased $1.5 million, primarily due to start-up activities related to the Phase 1b/2 study of rebastinib in combination with paclitaxel, which initiated in October 2018. Personnel-related costs increased $2.7 million due to increased headcount in our research and development functions. Personnel-related costs for the third quarters of 2018 and 2017 included non-cash share-based compensation expense of $1.1 million and $0.5 million, respectively.
G&A Expenses: General and administrative expenses for the third quarter of 2018 were $5.3 million, compared to $2.4 million for the same period in 2017. The increase was primarily due to an increase in non-cash share-based compensation expense related to additional employee stock options and a higher value of our common stock and to an increase in legal and professional fees as a result of various advisory fees related to ongoing operations as a public company. Facility-related and other costs increased due to director and officer insurance costs and higher rent expense related to our new lease. Non-cash share-based compensation was $1.5 million and $0.6 million for the third quarters of 2018 and 2017, respectively.
Net Loss: For the third quarter of 2018, Deciphera reported a net loss of $24.4 million, or $0.65 per share, compared with a net loss of $12.0 million, or $1.04 per share, for the same period in 2017.
