Diethylaminoreserpin (BIETASERPINE)

Phase 2 active Small molecule

Diethylaminoreserpin (generic name: BIETASERPINE) is a bietaserpine drug. It is currently in Phase 2 development.

Bietaserpine works by inhibiting certain cellular processes, although the exact target and mechanism are unknown.

Diethylaminoreserpin, also known as Bietaserpine, is a small molecule drug of the bietaserpine class. Its exact target and mechanism of action are unknown, but it is believed to work by inhibiting certain cellular processes. Bietaserpine's commercial status and approved indications are unclear, and it is not known whether it is patented or available as a generic medication. Further research is needed to fully understand its effects and potential uses. As a result, key safety considerations and pharmacokinetic properties, such as half-life and bioavailability, are also unknown.

Likelihood of approval

15.3% 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).

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.
