Triptolide Wilfordii

Peking Union Medical College Hospital · Phase 3 active Small molecule Under review

Triptolide Wilfordii is a Immunosuppressant Small molecule drug developed by Peking Union Medical College Hospital. It is currently in Phase 3 development for Rheumatoid arthritis.

Triptolide Wilfordii is a diterpenoid epoxide derived from the Chinese herb Tripterygium wilfordii, which has anti-inflammatory and immunosuppressive properties.

Triptolide is a small molecule with the synonyms NSC-163062 and TRIPTOLIDE, extracted from Tripterygium Wilfordii Hook F. It has been studied in clinical trials for conditions such as HIV, AIDS/HIV PROBLEM, HIV-infection/AIDS, and Polycystic Kidney disease.

Likelihood of approval
59.3% 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.
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
TGA AU 2029–2032 +1.2 yr
PMDA JP 2029–2032 +1.5 yr
NMPA CN 2030–2033 +2.3 yr

CDSCO IN 2029–2033 +1.8 yr
ANVISA BR 2030–2033 +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.
