Likelihood of approval
62.3% 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).
  • Immunology slight uplift +1.0pp
    Mature endpoint landscape (ACR, DAS28, PASI) makes immunology approvals slightly more predictable.
  • Big-pharma sponsor +3.0pp
    Janssen Research & Development, LLC is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.

Mechanism of action

Ustekinumab binds to the p40 subunit shared by both IL-12 and IL-23, preventing these cytokines from activating T cells and other immune cells that drive chronic inflammation. By inhibiting these pathways, it reduces pathogenic Th1 and Th17 cell responses implicated in autoimmune and inflammatory diseases. This dual IL-12/IL-23 inhibition provides broad immunomodulatory effects across multiple inflammatory conditions.
