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
MHRA GB 2029–2031 +0.7 yr

Mechanism of action

Eribulin mesylate is a non-taxane microtubule inhibitor that works by binding to the plus end of microtubules and inhibiting their growth phase while allowing shortening to continue, resulting in net loss of microtubule mass. This disruption of microtubule dynamics leads to G2/M cell cycle arrest and triggers apoptosis in rapidly dividing cancer cells. Unlike taxanes, eribulin does not stabilize microtubules but rather destabilizes them through a unique mechanism of action.
