Deciphera Pharmaceuticals says it will file an NDA in the second quarter of 2024 for vimseltinib for treating patients with tenosynovial giant cell tumor (TGCT) based on just-announced “positive top-line results” from the MOTION pivotal Phase 3 study of the drug in patients with TGCT not amenable to surgery.

“TGCT has a significant negative impact on the daily life of patients who face substantial pain, stiffness, and impaired mobility,” the company says. “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.”

Deciphera says the therapy met its primary endpoint in the intent-to-treat (ITT) population in the MOTION study, demonstrating statistically significant and clinically meaningful improvement versus placebo in the objective response rate (ORR) at week 25. “In the ITT population, the ORR at Week 25 was 40% (95% CI: 29%, 51%) for the vimseltinib arm and 0% (95% CI: 0%, 9%) for the placebo arm resulting in a response difference (vimseltinib versus placebo) of 40%,” it adds.
