Prof. Dr. Stephan Weidinger · Phase 2 active Small molecule ✓ Verified Jun 2026

Anti-IL17 is a Anti-inflammatory Small molecule drug developed by Prof. Dr. Stephan Weidinger. It is currently in Phase 2 development for Psoriasis, Plaque psoriasis.

IL-17 inhibitor

Anti-IL17 has been studied in clinical trials for various skin conditions, including Chronic Spontaneous Urticaria, Hidradenitis Suppurativa, Psoriasis, Atopic Dermatitis, and CTCL/ Mycosis Fungoides. The treatment has been investigated in combination with Ixekizumab, a monoclonal antibody targeting IL17, and has also been compared to a placebo in clinical trials.

Likelihood of approval
16.3% vs 15.3% industry baseline
If approved by FDA: likely 2031–2034
Steps remaining: Phase 3 → NDA/BLA submission
Confidence: Medium
Why this estimate
  • Baseline phase 2 → approval rate +15.3pp
    Industry-wide phase 2 drugs reach approval ~15.3% 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.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2031–2034
EMA EU 2032–2035 +0.7 yr
MHRA GB 2032–2035 +0.7 yr
Health Canada CA 2032–2036 +0.9 yr
TGA AU 2032–2036 +1.2 yr
PMDA JP 2032–2036 +1.5 yr
NMPA CN 2033–2037 +2.3 yr
MFDS KR 2032–2036 +1.4 yr
CDSCO IN 2032–2037 +1.8 yr
ANVISA BR 2033–2037 +2.3 yr

Hover any row for the lag rationale. Lag estimates are reduced when the drug has FDA Breakthrough or EMA PRIME designation (sponsors file globally in parallel).

Estimate based on the BIO/Informa industry phase transition rates plus per-drug modifiers for therapeutic area, sponsor type, FDA designations, mechanism, and trial design. Per-jurisdiction lags from Tufts CSDD international approval studies. Not investment, clinical or regulatory advice. Methodology: /methodology#likelihood.
