Tiadipone (BENTAZEPAM)

Phase 2 active Small molecule

Tiadipone (generic name: BENTAZEPAM) is a bentazepam drug. It is currently in Phase 2 development.

Tiadipone works by enhancing the activity of a neurotransmitter called GABA, which helps calm the brain and reduce anxiety.

Tiadipone, also known as BENTAZEPAM, is a small molecule drug in the bentazepam class. Its exact target is unknown, but it is used to treat anxiety disorders. The commercial status of Tiadipone is unclear, and it may be patented or have generic manufacturers. Key safety considerations are not well-documented. Further research is needed to fully understand its pharmacology and clinical use.

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

Mechanism of action

Think of GABA like a brake pedal in a car. When GABA is active, it helps slow down the activity of the brain, making it easier to relax and feel calm. Tiadipone helps GABA work more effectively, which can help reduce feelings of anxiety and fear.
