NCT07176689 | RECRUITING | Desmoid Tumor

Nirogacestat in Premenopausal Females With Desmoid Tumor/Aggressive Fibromatosis (DT/AF)
Sponsor:

SpringWorks Therapeutics, Inc.

Brief Summary:

This study is being conducted to study how nirogacestat may affect the ovarian function of adult premenopausal women with progressing desmoid tumors/aggressive fibromatosis.

Condition or disease

Desmoid Tumor

Aggressive Fibromatosis

Intervention/treatment

Nirogacestat

Phase

PHASE4

Detailed Description:

Desmoid tumors, also referred to as aggressive fibromatosis, are rare, locally invasive, slow growing soft tissue tumors. Although considered benign because of their inability to metastasize, desmoid tumors can cause significant morbidity and occasionally mortality in patients. Nirogacestat is a tumor inhibitor that works by slowing or stopping the growth of tumor cells. Nirogacestat is a tablet taken by mouth and has been approved in the USA for adult patients with progressing desmoid tumors who require systemic treatment. This is an open-label study to characterize the incidence and ovarian function recovery rates of ovarian toxicity (OT) events and to evaluate the efficacy, safety, and tolerability of nirogacestat in postpubertal and premenopausal females with desmoid tumors (DT).
