Lara Sullivan, MD, President and Founder at SpringWorks Therapeutics discusses the role of gamma-secretase inhibitors as an emerging therapy to treat desmoid tumors, a rare, non-metastatic tumor of connective tissue cells, which can cause severe morbidity, pain and loss of function in children and adults. Desmoid tumors can show up in almost any part of the body, and desmoids that are faster growing or located near vital organs can cause life-threatening problems.

Approximately 900-1,200 people are diagnosed with desmoid tumors each year in the U.S. Currently available treatments include unapproved medical therapy, radiation therapy, thermal ablation and surgery, which can be dangerous, costly and offer limited effectiveness. SpringWorks Therapeutics is planning to initiate a Phase 3 program to establish safety and efficacy of nirogacestat (PF-03084014), its gamma-secretase inhibitor, and will work collaboratively with the Desmoid Tumor Research Foundation to enable the needs of the patient community to be addressed.
