Likelihood of approval
63.3% 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).
  • Rare-disease pathway favourability +5.0pp
    Rare-disease drugs benefit from FDA Orphan Drug Act, smaller pivotal trials, and more flexible endpoints. Approval rates run ~5pp above baseline.
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
Health Canada CA 2029–2032 +0.9 yr

Mechanism of action

GM-CSF is a cytokine that promotes the differentiation and proliferation of hematopoietic progenitor cells into granulocytes and macrophages, thereby increasing their numbers and enhancing their antimicrobial and antitumor activity. By boosting innate immune cell populations and function, molgramostim aims to improve immune responses in conditions characterized by immune deficiency or dysfunction.
