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

Decitabine is a cytidine analog that incorporates into DNA and inhibits DNA methyltransferase (DNMT), reducing aberrant DNA methylation in cancer cells. This hypomethylating effect reactivates epigenetically silenced genes, including tumor suppressors, and promotes cell differentiation and apoptosis. Cedazuridine is a cytidine deaminase inhibitor that increases decitabine bioavailability by preventing its degradation, allowing for oral administration instead of intravenous infusion.
