Deciphera: MOTION study of vimseltinib met primary endpoint, key 2ndry endpoints

Deciphera Pharmaceuticals announced positive top-line results from the MOTION pivotal Phase 3 study of vimseltinib in patients with TGCT not amenable to surgery. Vimseltinib is the Company’s investigational, orally administered, potent, and highly selective switch-control kinase inhibitor of CSF1R. “Patients suffering from TGCT are in need of a new treatment option that offers both strong clinical benefit and a well-tolerated safety profile,” said Hans Gelderblom, M.D., Ph.D., Chair of the Department of Medical Oncology at Leiden University Medical Center. “TGCT has a significant negative impact on the daily life of patients who face substantial pain, stiffness, and impaired mobility. Success across both the primary and all key secondary endpoints in MOTION underscores vimseltinib’s ability to help TGCT patients feel and function better. The top-line results from MOTION, together with the impressive data announced today from the Phase 1/2 study showing that the response rates with vimseltinib continue to increase over time, and that patients continue to receive long-term clinical benefit as evidenced by the median duration of treatment, demonstrates vimseltinib’s potential to become a best-in-class agent.” “We are excited about the potential for vimseltinib to become our next approved medicine, supporting our continued evolution to a company with multiple marketed products,” said Steve Hoerter, President and Chief Executive Officer of Deciphera Pharmaceuticals. “The totality of data shown today demonstrate the potential for vimseltinib to offer a new and differentiated treatment option for patients with TGCT. On behalf of the entire Deciphera team, I would like to thank the patients, their caregivers, and the healthcare professionals who participated in the MOTION and Phase 1/2 studies. We look forward to working with regulatory agencies worldwide as we focus on delivering this important new treatment option to patients with TGCT.” Top-line Results from the MOTION Pivotal Phase 3 Study of Vimseltinib in TGCT.
