GSK3511294 is a TYK2 inhibitor Small molecule drug developed by GlaxoSmithKline. It is currently in Phase 3 development for Psoriasis, Inflammatory bowel disease. Also known as: Depemokimab.

GSK3511294 is a selective inhibitor of TYK2 (tyrosine kinase 2) that suppresses inflammatory signaling pathways involved in immune-mediated diseases.

GSK3511294, also known as Depemokimab, is an interleukin-5 inhibitor, a type of antibody that targets Interleukin-5. It is being studied in clinical trials for conditions such as asthma, nasal polyps, pulmonary disease, and chronic obstructive pulmonary disease.

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
    GlaxoSmithKline 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
Health Canada CA 2029–2032 +0.9 yr

Mechanism of action

TYK2 is a non-receptor tyrosine kinase that plays a critical role in type I and type III interferon signaling and IL-23 signaling. By selectively inhibiting TYK2, GSK3511294 reduces the activation and differentiation of pro-inflammatory T cells and other immune cells, thereby dampening pathogenic immune responses in autoimmune and inflammatory conditions.
