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.

Let’s innovate for the overlooked

Our late-stage rare oncology programs have the potential to be best-in-class treatments for patients with devastating diseases, including desmoid tumors, neurofibromatosis type 1-associated plexiform neurofibromas (NF1-PN) and low-grade gliomas.

Desmoid tumors
Desmoid tumors are a rare, aggressive soft-tissue tumor characterized by locally invasive growth, significant morbidity, and a high rate of recurrence.
NF1-PN
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 NF1-PN and low-grade gliomas. The Children’s Oncology Group (COG) clinical trial for children and adolescents with progressive, surgically unresectable desmoid tumors is fully enrolled in addition to the Phase 2b ReNeu clinical trial for children and adults with NF1-PN.

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.

NF1-PN

Our Phase 2b ReNeu clinical trial is evaluating mirdametinib in children (2 years or older) and in adults with an inoperable NF1-PN.

Ovarian granulosa cell tumors

A Phase 2 study is evaluating nirogacestat for the treatment of recurrent ovarian granulosa cell tumors (OvGCT).

Low-grade gliomas

A Phase 1/2 clinical trial is evaluating  mirdametinib for the treatment of children, adolescents, and young adults with low-grade glioma (LGG).

The safety and efficacy of nirogacestat has not been established in pediatric patients or in patients with ovarian granulosa cell tumors. The safety and efficacy of mirdametinib has not been established.
