FDA Extends Review of SpringWorks NDA
FDA has extended by three months its review of a SpringWorks Therapeutics NDA for nirogacestat for treating adults with desmoid tumors. The previous user fee review action date was 8/27.
FDA told the SpringWorks that it required more time to review the company’s analyses of submitted data that had been provided in response to an FDA information request, according to the company. The additional information was determined to be a major amendment to the NDA, requiring a longer review.
The submission is based on data from the Phase 3 DeFi trial which were published in the 3/9 New England Journal of Medicine. The company describes desmoid tumors as rare, aggressive, locally invasive tumors of soft tissues. “While they do not metastasize, desmoid tumors are associated with a high rate of recurrence,” it says.
