"In the third quarter, we made tremendous progress expanding the reach of QINLOCK for patients with GIST around the world. In addition to obtaining the approval for this important medicine in Switzerland and Taiwan, we also received a positive CHMP opinion for QINLOCK in the EU, with approval expected before the end of the year. Finally, we remain on track to report top-line results from the Phase 3 INTRIGUE study in second-line GIST later this quarter."

Mr. Hoerter continued, "At the European Society for Medical Oncology (ESMO) (Free ESMO Whitepaper) Congress 2021, we shared very encouraging data from both the vimseltinib and rebastinib programs demonstrating significant clinical activity in two diseases with high unmet medical needs. We plan to initiate the Phase 3 MOTION study of vimseltinib in tenosynovial giant cell tumor this quarter and expect to initiate a Phase 3 study of rebastinib in combination with paclitaxel in platinum-resistant ovarian cancer next year. The body of scientific evidence continues to build supporting the potential of our first-in-class ULK inhibitor, DCC-3116, to address a broad spectrum of cancers in which autophagy is upregulated and believed to play an important role in tumor growth and survival. The Phase 1/2 study of DCC-3116 is on track and, with the first-in-class program in this field, we are well positioned to explore the full potential of inhibiting autophagy in cancer."

Third Quarter 2021 Highlights and Upcoming Milestones

QINLOCK(ripretinib)
Recorded $21.7 million in QINLOCK net product revenue in the third quarter of 2021, including $20.0 million in U.S. sales of QINLOCK and $1.7 million in ex-U.S. sales of QINLOCK.
Presented data at the ESMO (Free ESMO Whitepaper) Congress 2021:
An exploratory evaluation of primary and secondary endpoints in the Phase 3 INVICTUS study, with a cutoff date of January 15, 2021, an additional 19 months after the primary analysis, demonstrated consistent progression-free survival (PFS) with no change since the primary data cut off, and improved median overall survival (OS) among patients receiving QINLOCK.
Median PFS was 6.3 months with QINLOCK compared to 1.0 month with placebo.
Median OS was 18.2 months with QINLOCK compared to 6.3 months with placebo.
Phase 1 study in patients with KIT-mutated or KIT-amplified melanoma.
Received approvals in Switzerland and Taiwan for the treatment of adult patients with advanced GIST who have received prior treatment with three or more kinase inhibitors, including imatinib.
Expects approval from the EMA for QINLOCK in the fourth quarter of 2021.
Expects to announce top-line results from the Phase 3 INTRIGUE study in the fourth quarter of 2021.
Expects to initiate a Phase 1b/2 study of QINLOCK in combination with binimetinib, a commercially available MEK inhibitor, in post-imatinib GIST patients in the fourth quarter of 2021.
Vimseltinib
Presented updated data from the ongoing Phase 1/2 study in patients with TGCT at the ESMO (Free ESMO Whitepaper) Congress 2021, showing an encouraging ORR of 47% across all cohorts and a manageable safety and tolerability profile.
Expects to initiate the pivotal Phase 3 MOTION study of vimseltinib in the fourth quarter of 2021. MOTION is a two-part, randomized, double-blind, placebo-controlled study of vimseltinib to assess the efficacy and safety in patients with symptomatic TGCT who are not amenable to surgery. The primary endpoint of the study is ORR at week 25 as measured by RECIST v1.1 by blinded independent central review.
Granted Fast Track Designation by the FDA for the treatment of patients with symptomatic TGCT who are not amenable to surgery. This designation is designed to facilitate the development and expedite the review of drugs to treat serious conditions and fill an unmet medical need.
Rebastinib
Presented updated data from the ongoing Phase 1b/2 study of rebastinib in combination with paclitaxel in the platinum-resistant ovarian cancer (PROC) cohort at the ESMO (Free ESMO Whitepaper) Congress 2021. Data showed promising results including median PFS of 9.1 months and an ORR of 38% (confirmed and unconfirmed) in heavily pretreated patients with PROC.
Received Orphan Drug Designation in the EU for the treatment of ovarian cancer based on a positive opinion issued by the EMA Committee for Orphan Medicinal Products (COMP).
Announced that the Company has begun planning for a pivotal study in PROC that is anticipated to start in 2022, subject to feedback from regulators.
DCC-3116
Presented preclinical data at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) showing that DCC-3116 inhibits EGFR inhibitor-induced autophagy in multiple EGFR-mutant non-small cell lung cancer cell lines and decreased tumor burden in combination with osimertinib and afatinib in an EGFR mutant xenograft model.
Announced plans to present initial data from the dose escalation phase of the Phase 1 study in 2022.
Third Quarter Financial Results

Revenue: Total revenue for the third quarter of 2021 was $23.2 million, which includes $21.7 million of net product revenue from sales of QINLOCK and $1.5 million of collaboration revenue comprised primarily of QINLOCK supply and royalty revenue under our license agreement with Zai Lab. Total revenue for the third quarter of 2020 was $15.5 million, which included $15.2 million of net product revenue from sales of QINLOCK and $0.3 million of collaboration revenue.
Cost of Sales: Cost of sales was $0.9 million in the third quarter of 2021, which includes $0.2 million in cost of net product revenue for QINLOCK and $0.7 million in cost of collaboration revenue. Cost of sales was $0.1 million for the third quarter of 2020. Deciphera does not expect that the cost of sales as a percentage of net product sales of QINLOCK will increase significantly after the Company has sold all zero cost inventories and commenced the sales of inventories which will reflect the full cost of manufacturing. The Company expects to continue to sell the zero cost inventories of QINLOCK in the U.S. during 2021 and into 2022.
R&D Expenses: Research and development expenses for the third quarter were $66.4 million, compared to $49.2 million for the same period in 2020. The increase was primarily due to personnel and preclinical costs, and a $4.0 million up-front payment to Sprint Bioscience (Sprint) pursuant to the terms of the agreement with Sprint to exclusively in-license worldwide rights to a research-stage program targeting VPS34, and an increase in clinical trial expenses related to start-up activities for the planned Phase 3 MOTION study of vimseltinib and Phase 1b/2 study of QINLOCK in combination with binimetinib. Non-cash, stock-based compensation was $5.4 million and $4.5 million for the third quarters of 2021 and 2020, respectively.
SG&A Expenses: Selling, general, and administrative expenses for the third quarter of 2021 were $35.5 million, compared to $30.1 million for the same period in 2020. The increase was primarily due to personnel costs as well as external spend related to professional fees, including those associated with establishing a targeted commercial infrastructure and commercial preparedness in key European markets to support a launch of QINLOCK in Europe, if approved. Non-cash, stock-based compensation was $6.4 million and $5.3 million for the third quarters of 2021 and 2020, respectively.
Net Loss: For the third quarter of 2021, Deciphera reported a net loss of $79.8 million, or $1.37 per share, compared with a net loss of $63.7 million, or $1.13 per share, for the same period in 2020. The increase in net loss was primarily a result of increased R&D expenses, as described above, partially offset by increased sales volume in the U.S.
Cash Position: As of September 30, 2021, cash, cash equivalents, and marketable securities were $392.2 million, compared to $451.0 million as of June 30, 2021. Based on its current operating plans, Deciphera expects its current cash, cash equivalents, and marketable securities together with anticipated product, royalty, and supply revenues, excluding any potential future milestone payments under the Zai License Agreement, will enable the Company to fund its operating and capital expenditures into the first half of 2023.
