Depressin (PROPIZEPINE)

Phase 2 active Small molecule

Depressin (generic name: PROPIZEPINE) is a propizepine drug. It is currently in Phase 2 development.

Depressin is thought to work by interacting with a specific target in the brain, although its exact mechanism is unknown.

Depressin (PROPIZEPINE) is a small molecule drug in the propizepine class, but its target and mechanism of action are unknown. It is not clear if it is FDA-approved or commercially available. There is limited information available on its pharmacokinetic properties, such as half-life and bioavailability. Depressin is not listed as an approved indication, and its commercial status is unclear. Further research is needed to understand its clinical use and safety profile.

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

Imagine your brain is a complex computer, and Depressin is a software update that tries to fix a specific problem. However, since its target and mechanism are unknown, it's like trying to fix a problem without knowing what's causing it. More research is needed to understand how it works and what it does.
