Iprazid (IPRONIAZID)

Phase 2 active Small molecule Under review

Iprazid (generic name: IPRONIAZID) is a Monoamine Oxidase Inhibitors drug. It is currently in Phase 2 development for Depressive disorder.

Iproniazid works by blocking the enzyme that breaks down certain neurotransmitters, allowing their levels to increase in the brain.

Iprazid is a small molecule inhibitor of the enzyme monoamine oxidase. It is classified as a monoamine oxidase inhibitor, a drug class that inhibits the action of monoamine oxidase.

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.

Mechanism of action

Imagine your brain is a city with many roads. Neurotransmitters are like cars that travel along these roads, carrying messages between different parts of the brain. Iproniazid is like a traffic cop that stops the 'breakdown' of these cars, allowing more of them to be available to carry messages, which can help improve mood and reduce symptoms of depression.
