SpringWorks Therapeutics has announced that it has submitted a New Drug Application to the U.S. FDA for nirogacestat, their investigational gamma secretase inhibitor for the treatment of adults with desmoid tumors. 

“Our NDA submission represents an important step toward potentially delivering the first approved therapy for patients with desmoid tumors.”

What Happens Next 

Once submitted, the FDA has about 60 days to decide whether to “accept” the New Drug Application (NDA). If accepted, the official FDA review process will start. 

A standard FDA review process is typically about 10 months. SpringWorks has applied for various regulatory designations that the FDA has in place to review drugs that treat serious conditions and fulfill an unmet need. The FDA granted nirogacestat Fast-Track and Breakthrough Therapy Designations in the past, and SpringWorks also plans to submit the NDA for review under the FDA’s Real-Time Oncology Review program. 

All of this is good news and means that there is recognition that there is an important need for a new drug like nirogacestat.

Because there are many variables with the FDA approval process, SpringWorks is only able to say right now that it expects the FDA to make a decision sometime in 2023. As more precise timelines become available, SpringWorks will let the DTRF know, and we will then be able to update our community.
