Systemic therapy for pediatric desmoid tumors has been challenged by a lack of high-quality clinical evidence and potential adverse effects. The gamma-secretase inhibitor nirogacestat has shown promising efficacy in adults. We report four cases of pediatric and young adult desmoid tumor patients (three with familial adenomatous polyposis [FAP] syndrome) who received nirogacestat on compassionate use. After a median of 13.5 months (range 6-18), three had durable benefit: a complete response (Case 1); a partial response (Case 2); stable disease (Case 3). The fourth had disease progression after a partial response. No patient experienced grade 3 or 4 adverse events.
