news.SpringWorks Therapeutics, Inc. a clinical-stage biopharmaceutical company focused on developing life-changing medicines for patients with severe rare diseases and cancer, today announced the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for nirogacestat, an oral, selective, small molecule, gamma-secretase inhibitor, for the treatment of adult patients with progressive, unresectable, recurrent or refractory desmoid tumors or deep fibromatosis.

The Breakthrough Therapy Designation was based on Phase 1 and Phase 2 data evaluating nirogacestat as a monotherapy in patients with desmoid tumors.
Desmoid tumors are rare and often debilitating and disfiguring soft-tissue tumors that can aggressively invade surrounding healthy tissues and cause significant morbidities, including severe pain, internal bleeding, incapacitating loss of range of motion, and, in rare cases, death.1 It is estimated that 1,000 to 1,500 new desmoid tumor patients are diagnosed each year in the United States.2,3 There are currently no therapies approved by the FDA for the treatment of desmoid tumors.
“We are committed to pursuing the rapid development of nirogacestat given the important need for new therapies for patients with desmoid tumors and are pleased to receive this Breakthrough Therapy Designation,” said Saqib Islam, Chief Executive Officer of SpringWorks. “We are currently enrolling adult patients in our Phase 3 DeFi trial and will continue to work closely with the FDA with the goal of bringing nirogacestat to patients as quickly as possible.”
The FDA’s Breakthrough Therapy Designation is designed to expedite the development and regulatory review of medicines that are intended to treat a serious condition. To qualify for this designation, preliminary clinical evidence must demonstrate that the medicine may provide substantial improvement over currently available therapy on at least one clinically significant endpoint.4
Previously, the FDA had granted nirogacestat Orphan Drug Designation for the treatment of desmoid tumors (June 2018) and Fast Track Designation for the treatment of adult patients with progressive, unresectable, recurrent or refractory desmoid tumors or deep fibromatosis (November 2018).
Desmoid tumors, also referred to as aggressive fibromatosis or desmoid-type fibromatosis, are rare and often debilitating and disfiguring soft tissue tumors characterized by a growth pattern that can invade surrounding healthy tissues, including joints, muscle and viscera. While they can arise in any part of the body, the most common sites are the upper and lower extremities, abdominal walls, thoracic areas, and the head and neck. The severity of a desmoid tumor can vary based on the location of the tumor and the aggressiveness of its growth pattern. Desmoid tumors can cause significant morbidities, including severe pain, internal bleeding, incapacitating loss of range of motion, and, in rare cases, death.
