Brivudin (BRIVUDINE)

Phase 2 active Small molecule ✓ Verified May 2026

Brivudin (generic name: BRIVUDINE) is a brivudine drug. It is currently in Phase 2 development.

Brivudin works by mimicking the structure of a nucleoside, which is then incorporated into viral DNA, causing chain termination and preventing viral replication.

Brivudin, also known as brivudine phosphoramidate, is a medication used to treat Herpes Zoster and has been studied in clinical trials for its potential use in treating Colorectal Cancer.

Likelihood of approval
17.3% 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).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates above baseline.
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

Mechanism of action

Imagine your body's cells are like factories that build new parts. Brivudin is like a faulty part that gets inserted into the viral DNA, causing the factory to stop working properly and preventing the virus from making more copies of itself.
