    Deciphera Pharmaceuticals, Inc. (NASDAQ:DCPH), a clinical-stage biopharmaceutical company focused on addressing key mechanisms of tumor drug resistance, today reported updated data from its ongoing Phase 1 clinical study of ripretinib, a broad-spectrum KIT and PDGFRα inhibitor, in patients with second-line through fourth-line plus gastrointestinal stromal tumors (GIST).

    In a separate press release issued today, Deciphera announced positive top-line results from its INVICTUS pivotal Phase 3 clinical study supporting a potential new drug application (NDA) submission to the U.S. Food and Drug Administration (FDA) for ripretinib for the treatment of patients with advanced GIST who have received prior treatment with imatinib, sunitinib and regorafenib. In addition to the INVICTUS data, Deciphera will also be submitting in its NDA supportive data from the ongoing Phase 1 clinical study, which will include the updated data from GIST patients at doses of >100mg of ripretinib. Additional results from the Phase 1 clinical study in these patients are expected to be presented at an upcoming medical meeting.

    “We believe the updated data from our ongoing Phase 1 clinical study, with the additional six months of maturity from our last Phase 1 data cut-off, continue to support ripretinib’s potential across the broad range of KIT and PDGFRα mutations known to occur in patients with GIST following therapy with imatinib,” said Steve Hoerter, President and Chief Executive Officer of Deciphera. “In the updated data from the second-line cohort, we believe ripretinib has demonstrated encouraging clinical benefit based on the objective response rate, disease control rate and median progression free survival rates observed. These results strengthen our confidence in the INTRIGUE pivotal Phase 3 clinical study comparing ripretinib to sunitinib, the standard of care for patients receiving second-line treatment for GIST.”
