China NMPA Approves QINLOCK® (Ripretinib) for Treatment of Advanced Gastrointestinal Stromal Tumors (GIST)
China NMPA approval follows 2020 U.S. FDA approval for the treatment of patients with fourth-line GIST
QINLOCK demonstrated a significant improvement in progression-free survival and a clinically meaningful benefit in overall survival compared to placebo in the pivotal Phase 3 INVICTUS study
QINLOCK approval is the third innovative oncology product approval Zai Lab received in the last 15 months
SHANGHAI, SAN FRANCISCO, CA and WALTHAM, MA, March 31, 2021 — Zai Lab (NASDAQ: ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, and Deciphera Pharmaceuticals (NASDAQ: DCPH), a commercial-stage biopharmaceutical company developing innovative medicines to improve the lives of people with cancer, today announced that the China National Medical Products Administration (NMPA) has approved its New Drug Application (NDA) for QINLOCK® (ripretinib) for the treatment of adult patients with advanced gastrointestinal stromal tumors (GIST) who have received prior treatment with three or more kinase inhibitors, including imatinib. QINLOCK targets the broad spectrum of KIT and PDGFRα mutations known to drive GIST.
“Treatment of GIST remains an important unmet medical need in China,” said Dr. Samantha Du, Founder, Chairperson, and Chief Executive Officer of Zai Lab. “Approximately 30,000 GIST patients are newly diagnosed each year in China, twice as many as in the U.S. and Europe combined. NMPA’s approval of QINLOCK establishes a new standard of care for treating patients with fourth-line GIST in China. We appreciate the NMPA’s rapid and thorough assessment of QINLOCK. We look forward to working closely with our partner, Deciphera, to introduce this new treatment option to benefit many more patients who are suffering from advanced GIST in Greater China.”
“We congratulate Zai on gaining this important approval,” said Steve Hoerter, President and Chief Executive Officer of Deciphera. “QINLOCK is a new standard of care for patients with fourth-line GIST, and we’re excited to work with our partner Zai as they deliver this innovative medicine to patients in China.”
“The approval of QINLOCK in China is a significant milestone for the GIST community,” said Dr. Shukui Qin, Chief Physician of Cancer Center, Nanjing Jinling Hospital, Senior Vice President of the Chinese Society of Clinical Oncology. “Many GIST patients, who initially responded to traditional tyrosine kinase inhibitors, ultimately developed tumor progression due to secondary mutations. QINLOCK may potentially alter the treatment landscape for patients in China with GIST.”
“Based on the pivotal Phase 3 INVICTUS study, QINLOCK demonstrated compelling clinical benefit in progression-free and overall survival, and was shown to have a favorable safety profile in treating advanced GIST patients,” said Dr. Lin Shen, Vice President of Clinical Oncology at Beijing Cancer Hospital. “We look forward to making this innovative therapy available to patients as soon as possible.”
Deciphera and Zai Lab are also exploring the use of QINLOCK to treat patients with second-line GIST. Deciphera has completed target enrollment in the Phase 3 INTRIGUE study of QINLOCK in patients with second-line GIST, with top-line results anticipated in the second half of 2021.
About QINLOCK (ripretinib)
QINLOCK is a switch-control tyrosine kinase inhibitor that was engineered to broadly inhibit KIT and PDGFRα mutated kinases by using a dual mechanism of action that regulates the kinase switch pocket and activation loop. QINLOCK inhibits primary and secondary KIT mutations in exons 9, 11, 13, 14, 17, and 18 involved in GIST, as well as the primary exon 17 D816V mutation. QINLOCK also inhibits primary PDGFRα mutations in exons 12, 14, and 18, including the exon 18 D842V mutation, involved in a subset of GIST.
In March 2021, the NMPA approved QINLOCK for the treatment of adult patients with advanced GIST who have received prior treatment with three or more kinase inhibitors, including imatinib. In March 2021, the Hong Kong Department of Health approved QINLOCK in Hong Kong for the treatment of adult patients with advanced GIST who have received prior treatment with imatinib, sunitinib, and regorafenib. In May 2020, the U.S. FDA approved QINLOCK for the treatment of adult patients with advanced GIST who received prior treatment with three or more kinase inhibitors, including imatinib. It is also approved by Health Canada for the treatment of adult patients with advanced GIST who have received prior treatment with imatinib, sunitinib, and regorafenib and by the Australian Therapeutic Goods Administration for the treatment of adult patients with advanced GIST who have received prior treatment with three or more kinase inhibitors, including imatinib.
Zai Lab has an exclusive license agreement with Deciphera for the development and commercialization of ripretinib in Greater China (mainland China, Hong Kong, Macau and Taiwan).
About the INVICTUS Phase 3 Study
INVICTUS is a Phase 3 randomized, double-blind, placebo-controlled, international, multicenter clinical study evaluating the safety, tolerability, and efficacy of QINLOCK compared to placebo in patients with advanced GIST whose previous therapies have included imatinib, sunitinib, and regorafenib. Patients were randomized 2:1 to either 150 mg of QINLOCK or placebo once daily. The primary efficacy endpoint is progression-free survival (PFS) as determined by independent radiologic review using modified Response Evaluation Criteria in Solid Tumors (RECIST). The median PFS in the study was 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). Secondary endpoints as determined by independent radiologic review using modified RECIST include Objective Response Rate (ORR) and Overall Survival (OS). QINLOCK demonstrated an ORR of 9.4% compared with 0% for placebo (p =0.0504). QINLOCK also demonstrated a median OS 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).
Important Safety Information
There are no contraindications for QINLOCK. The most common adverse reactions (³20%) were alopecia, fatigue, nausea, abdominal pain, constipation, myalgia, diarrhea, decreased appetite, palmar-plantar erythrodysesthesia syndrome (PPES), and vomiting. The most common Grade 3 or 4 laboratory abnormalities (³4%) were increased lipase and decreased phosphate.
