Likelihood of approval
60.3% 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).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates 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

This vaccine candidate uses recombinant DNA or gene-based technology to express hepatitis B antigens and stimulate both cellular and humoral immune responses. It is intended to provide therapeutic benefit in patients with chronic hepatitis B infection by enhancing immune control of the virus, rather than serving as a preventive vaccine for naive populations.
