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).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates above baseline.
  • Big-pharma sponsor +3.0pp
    AbbVie is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
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

Ombitasvir is a NS5A inhibitor that works by binding to the NS5A protein of the hepatitis C virus, preventing the virus from replicating. Paritaprevir is a protease inhibitor that works by binding to the NS3/4A protease of the hepatitis C virus, preventing the virus from replicating. Ritonavir is a protease inhibitor that is used in combination with other medications to increase their effectiveness and reduce the risk of resistance.
