Terizidon (TERIZIDONE)

Phase 2 active Small molecule ✓ Verified May 2026

Terizidon (generic name: TERIZIDONE) is a terizidone drug. It is currently in Phase 2 development.

Terizidone works by inhibiting the activity of certain enzymes in the brain.

Terizidon is a small molecule used in the treatment of tuberculosis, including multidrug-resistant and extensively-drug resistant forms, as well as HIV infections. It is administered as part of individualized or standardized treatment regimens, often in combination with other drugs.

Likelihood of approval
12.3% 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).
  • CNS / neurology attrition -3.0pp
    CNS drugs have historically high Phase 3 failure rates (notably in Alzheimer disease + major depression).
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.

Mechanism of action

Think of it like a key that unlocks a door. In this case, the key is terizidone, and the door is the brain's ability to make certain chemicals that can cause problems. By blocking these chemicals, terizidone can help reduce symptoms of certain conditions.
