Nirogacestat oral tablet

SpringWorks Therapeutics, Inc. · Phase 3 active Small molecule ✓ Verified May 2026

Nirogacestat oral tablet is a Gamma-secretase inhibitor Small molecule drug developed by SpringWorks Therapeutics, Inc.. It is currently in Phase 3 development for Desmoid tumors (aggressive fibromatosis). Also known as: PF-03084014, Ogsiveo.

Nirogacestat inhibits gamma-secretase, reducing the production of Notch intracellular domain and downstream signaling that drives abnormal cell proliferation in desmoid tumors.

Nirogacestat oral tablet is a small molecule gamma-secretase inhibitor used to treat various conditions, including triple negative breast neoplasms, advanced solid tumors, and desmoid tumors. It is classified as an inhibitor and is used as a single-agent treatment in patients with advanced breast cancer and other conditions.

Likelihood of approval
61.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Oncology Phase 3 boost +3.0pp
    Oncology Phase 3 trials have higher approval rates (~61%) than the cross-industry average due to clearer endpoints and FDA oncology pathway.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr

Mechanism of action

Gamma-secretase is an intramembrane protease complex that cleaves Notch receptors and other substrates. In desmoid tumors, aberrant Notch signaling promotes fibroblast proliferation and tumor growth. By blocking gamma-secretase activity, nirogacestat suppresses Notch-driven proliferation and induces tumor regression or stabilization. This mechanism is particularly relevant in desmoid tumors with CTNNB1 mutations that activate Wnt/β-catenin signaling, which cooperates with Notch signaling.
