Ogsiveo, nirogacestat
Named-patient access overview. Ogsiveo is coordinated by Reserve Meds for international patients via physician-led cross-border sourcing.
About Ogsiveo
Ogsiveo (nirogacestat) is manufactured by SpringWorks Therapeutics and was approved by the US FDA in November 2023 for adult patients with progressing desmoid tumors who require systemic treatment. Desmoid tumors are a form of aggressive fibromatosis: locally invasive soft-tissue tumors that, while not metastatic, can cause significant morbidity through infiltration of surrounding structures. Ogsiveo is an oral, selective small-molecule gamma-secretase inhibitor; by reducing gamma-secretase activity it suppresses downstream Notch signalling and influences the Wnt / beta-catenin pathway activity implicated in desmoid biology, which is the mechanism supported by the DeFi Phase 3 pivotal trial.
Ogsiveo is taken by mouth twice daily as set out in the prescribing information, with monitoring for diarrhea, electrolyte disturbance, rash, headache, and hepatotoxicity. The label highlights ovarian toxicity, including premature ovarian insufficiency, as a notable risk in females of reproductive potential, and counselling on this risk is required before treatment. For international patients, Ogsiveo may be coordinated through Named Patient Program or personal-import pathways with the destination country's regulator and the patient's treating physician handling the documentation.
