DCPH stock has setup into a sweet swing long pattern on a candle over candle reversal on Friday, May 15, 2020.

On May 15, 2020, Deciphera Pharmaceuticals, Inc. (NASDAQ:DCPH) announced the FDA has approved QINLOCK™ (ripretinib) for the treatment of adult patients with advanced gastrointestinal stromal tumor (GIST) who have received prior treatment with 3 or more kinase inhibitors, including imatinib. The FDA previously granted Breakthrough Therapy and Fast Track designations as well as Priority Review for QINLOCK and reviewed the New Drug Application (NDA) under the Real-Time Oncology Review (RTOR) pilot program. The QINLOCK NDA is also part of Project Orbis, an initiative of the FDA Oncology Center of Excellence that provides a framework for concurrent submission and review of oncology drugs among participating international health authorities. QINLOCK targets the broad spectrum of KIT and PDGFRα mutations known to drive GIST.

“Today’s approval of QINLOCK establishes a new standard of care for patients who have received three prior therapies,” said Margaret von Mehren, MD, Chief of Sarcoma Oncology and Associate Director for Clinical Research, Fox Chase Cancer Center, Philadelphia, Pennsylvania. “GIST is a complex disease and the majority of patients who initially respond to traditional tyrosine kinase inhibitors eventually develop tumor progression due to secondary mutations. In the INVICTUS study, QINLOCK has demonstrated compelling clinical benefit in progression-free and overall survival. QINLOCK is well tolerated and is a crucial new therapy for these patients with a high unmet need.”

“The FDA approval of QINLOCK is an exciting milestone for people with GIST who have been waiting for a new treatment option designed specifically for their disease,” said Steve Hoerter, President and Chief Executive Officer of Deciphera. “I would like to thank the patients, their families and caregivers, and the healthcare professionals who made the QINLOCK clinical studies possible. With their contributions and the dedication of the team at Deciphera, we are delivering on our promise to provide important new medicines for the treatment of cancer.”

The FDA approval was based on efficacy results from the pivotal Phase 3 INVICTUS study of QINLOCK in patients with advanced GIST as well as combined safety results from INVICTUS and the Phase 1 study of QINLOCK. In INVICTUS, QINLOCK demonstrated a median progression-free survival of 6.3 months compared to 1.0 month in the placebo arm and significantly reduced the risk of disease progression or death by 85% (hazard ratio of 0.15, p<0.0001). In addition, QINLOCK demonstrated a median overall survival of 15.1 months compared to 6.6 months in the placebo arm and reduced the risk of death by 64% (hazard ratio of 0.36).

The most common adverse reactions (≥20%) were alopecia, fatigue, nausea, abdominal pain, constipation, myalgia, diarrhea, decreased appetite, palmar-plantar erythrodysesthesia syndrome (PPES), and vomiting. Adverse reactions resulting in permanent discontinuation occurred in 8% of patients, dosage interruptions due to an adverse reaction occurred in 24% of patients and dose reductions due to an adverse reaction occurred in 7% of patients who received QINLOCK.

Deciphera Pharmaceuticals plans to make QINLOCK commercially available in the U.S. next week.

On May 6, 2020, H.C. Wainwright analyst Andrew Fein raised the firm’s price target on Deciphera Pharmaceuticals to $80 from $60 and keeps a Buy rating on the shares. The analyst sees multiple catalysts beyond the ripretinib launch. The DCC-3014 recommended Phase 2 dose selection and expansion into the tenosynovial giant cell tumor patients in the second half of 2020, data updates from the Phase 1b/2 study of rebastinib in combination with paclitaxel expected at ASCO, and ripretinib data from at least one expansion cohort excluding GIST should continue to drive value for Deciphera.
