Ripretinib

Application submitted for manufacturing and marketing approval of ripretinib in Japan for the indication of “gastrointestinal stromal tumor that has progressed following cancer chemotherapy” Ripretinib has significantly prolonged the primary endpoint of progression-free survival compared to placebo in the INVICTUS study Already approved in the United States and Europe; recognized as a highly necessary medicine by the government review committee addressing drug loss in Japan Ono Pharmaceutical Co., Ltd. (Headquarters: Osaka, Japan; President: Toichi Takino; “Ono”) today announced that Ono submitted an application for the manufacturing and marketing approval of ripretinib (DCC-2618), developed by Deciphera Pharmaceuticals, Inc. (“Deciphera”), for the indication of “gastrointestinal stromal tumor that has progressed following cancer chemotherapy.” This application is based on the results of the INVICTUS study, a global Phase 3 clinical study, evaluating the efficacy of ripretinib compared to placebo in patients with advanced gastrointestinal stromal tumor (GIST) who have received prior treatment with 3 or more kinase inhibitors, including imatinib. In this study, ripretinib significantly prolonged the primary endpoint of progression-free survival (PFS) compared to placebo. “GIST is recognized as a rare disease worldwide, and ripretinib, developed by Deciphera, has already been approved in more than 40 countries and regions, including the United States and Europe. This application for approval of ripretinib represents a significant advancement for patients with GIST in Japan,” said Tatsuya Okamoto, Corporate Officer / Executive Director, Clinical Development of Ono. “Moving forward, we remain committed to developing and providing innovative medicines to meet the treatment needs of patients and the expectations of society.” “The application submission brings us one step closer to providing patients in Japan with advanced GIST a potential new treatment option. We anticipate that this submission may help address the issue of delayed access to new medicines, which remains a significant challenge for patients in Japan,” said Ryota Udagawa, President and Chief Executive Officer of Deciphera. “As GIST is a rare type of tumor, the limited availability of disease information and current treatment options are likely to cause significant anxiety for patients. Together with our group companies, we will continue to make every effort to deliver ripretinib to patients in Japan suffering from advanced GIST as quickly as possible.” The INVICTUS Phase 3 clinical study is a randomized, double-blind, placebo-controlled, international, multicenter study conducted in 12 overseas countries including US and EU to evaluate the safety, tolerability, and efficacy of ripretinib compared to placebo in 129 patients with advanced GIST who have received prior treatment with 3 or more kinase inhibitors, including imatinib. Patients were randomized 2:1 to either 150 mg of ripretinib or placebo once daily. In the INVICTUS study, ripretinib significantly prolonged the primary endpoint of PFS determined by independent central radiologic review (a median PFS of 6.3 months in ripretinib arm compared to 1.0 month in the placebo arm, HR of 0.15, p<0.0001). 1) GIST is a mesenchymal tumor that arises from the muscular layer of the gastrointestinal tract and forms a mass that pushes up the mucosa from below. GIST is a rare disease, with an incidence of approximately 1 to 2 cases per 100,000 population per year. In Japan, the number of patients diagnosed with GIST between 2016 and 2018 was 4,475 over three years (approximately 1,492 cases per year; crude incidence rate: 1.18 cases per 100,000 population). 2) It is known that mutations in KIT (KIT proto-oncogene receptor tyrosine kinase) and PDGFRα (platelet-derived growth factor receptor α) are involved in the development of the majority of patients with GIST. For unresectable, metastatic, or recurrent GIST, four agents—imatinib, sunitinib, regorafenib, and pimitespib—are currently approved in Japan. According to the Japanese clinical practice guidelines for GIST, these agents are recommended as first-line, second-line, third-line, and fourth-line treatments, respectively. 3) Ripretinib is an orally administered, tyrosine kinase inhibitor developed by Deciphera. Ripretinib inhibits primary and secondary KIT mutations in exons 9, 11, 13, 14, 17, and 18, which are involved in GIST. In addition, ripretinib inhibits primary PDGFRα mutations in exons 12, 14, and 18, including the exon 18 D842V mutation, which is present in a subset of GIST. The INVICTUS study has demonstrated the significant efficacy of ripretinib in patients with advanced GIST who have received prior treatment with 3 or more kinase inhibitors, including imatinib. Ripretinib was launched in the U.S. in 2020 under the brand name QINLOCK®. As of March 2026, it is approved for the treatment of advanced GIST in more than 40 countries or regions, including the U.S. and European countries. In Japan, ripretinib was designated as an orphan drug by the Ministry of Health, Labour and Welfare on March 19, 2026, for the treatment of GIST that have progressed following cancer chemotherapy. In addition, ripretinib was determined as a drug with high medical needs at the "67th Evaluation Committee on Unapproved or Off-label Drugs with High Medical Needs" held by Ministry of Health, Labour and Welfare, aiming to eliminate drug losses in Japan.

The molecule was in an open-label phase 1/2 study for multiple types of solid tumor driven by the MAPK pathway, both as a monotherapy and in combination with other drugs.\n Ono Pharmaceutical subsidiary Deciphera Pharmaceuticals has dropped an early-stage candidate for advanced cancers from its pipeline.DCC-3084, a pan-RAF inhibitor, “is no longer in our pipeline and we are currently not planning additional development at this time,” a Deciphera spokesperson confirmed to Fierce Biotech on Tuesday. The decision was made for strategic reasons and unrelated to the asset’s safety or efficacy, they explained.“Given that it was such an early-stage program, employees working on it were simply reassigned to another program and there were no layoffs,” the spokesperson added.The molecule was in an open-label phase 1/2 study for multiple types of solid tumor driven by the MAPK pathway, both as a monotherapy and in combination with other drugs. The now-terminated trial kicked off in May 2024 and enrolled 29 total patients, according to the federal clinical trial database. Japanese drugmaker Ono acquired Deciphera for $2.4 billion in mid-2024, gaining the already approved gastrointestinal cancer med Qinlock and the rare tumor drug vimseltinib, which was later approved as Romvimza.Even with DCC-3084 sent to the scrap heap, Deciphera still boasts a packed pipeline led by BTK inhibitor tirabrutinib and antisense oligonucleotide sapablursen. Tirabrutinib was discovered by Ono and is approved in Japan, South Korea and Taiwan as Velexbru. The candidate is currently being considered for FDA approval in relapsed or refractory primary central nervous system lymphoma, with a decision expected by Dec. 18. Deciphera is now running a phase 3 confirmatory trial in the indication.Sapablursen, meanwhile, was licensed by Ono from Ionis Pharmaceuticals for $280 million upfront in March 2025. Ionis shared positive phase 2 data for the oligo in polycythemia vera, a rare blood cancer, at the American Society of Hematology meeting last December. Deciphera expects to launch a phase 3 trial for sapablursen this year.
