On Nov. 27, 2023, the U.S. Food and Drug Administration approved SpringWorks’ Ogsiveo (nirogacestat) tablets for adult patients with progressing desmoid tumors who require systemic treatment. Ogsiveo is the first drug to be approved for the treatment of patients with desmoid tumors, a rare subtype of soft tissue sarcomas.

Desmoid tumors are non-cancerous but can be locally aggressive. The tumors may invade into surrounding structures and organs, resulting in pain, issues with being able to move, and decreased quality of life.
