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).
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
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

Fentanyl is a synthetic opioid that activates mu-opioid receptors, inhibiting pain signal transmission and producing analgesia. The nasal formulation allows for rapid absorption through the nasal mucosa, bypassing first-pass hepatic metabolism and providing faster onset compared to oral routes. This makes it particularly suitable for acute or breakthrough pain management.
