Rare Oncology

Too many loved ones live with uncertainty.
Let’s find answers.

Rare oncology is where rare diseases and cancers meet. While some rare tumors are not malignant, their presence and progression can be nonetheless devastating for patients. At SpringWorks, we are relentless in the search for answers because people with these often-overlooked conditions can’t wait.

Desmoid tumors are a rare, aggressive soft-tissue tumor characterized by locally invasive growth, significant morbidity, and a high rate of recurrence.
About 30-50% of people with neurofibromatosis type 1 (NF1) develop plexiform neurofibromas (PN), which are peripheral nerve sheath tumors that can cause significant pain, disfigurement, and functional impairment.
Desmoid tumors are difficult to live with because of the pain and numbness I feel in my hands. I love painting, and it is what keeps me going despite how challenging life can be. I have found creative ways to paint without the use of my hands, such as using straws to get the paint on paper.

Clinical trials

Clinical trials are underway to evaluate nirogacestat for pediatric patients with desmoid tumors and ovarian granulosa cell tumors, and to evaluate mirdametinib for patients with low-grade gliomas. The Children’s Oncology Group (COG) clinical trial for children and adolescents with progressive, surgically unresectable desmoid tumors is fully enrolled.

Desmoid tumors

Under a collaboration with Children’s Oncology Group (COG), a Phase 2 clinical trial is evaluating nirogacestat as a monotherapy in children and adolescents with progressive, surgically unresectable desmoid tumors.
