Chlordemethyldiazepam (DELORAZEPAM)

Phase 2 active Small molecule ✓ Verified May 2026

Chlordemethyldiazepam (generic name: DELORAZEPAM) is a delorazepam drug. It is currently in Phase 2 development.

Delorazepam works by enhancing the activity of the neurotransmitter GABA, which helps to calm excessive neuronal activity in the brain.

Chlordemethyldiazepam is a small molecule with unknown efficacy in treating Anorexia Nervosa and Bulimia Nervosa, as indicated by ClinicalTrials.gov. It has been studied in combination with Cognitive Behavioral Therapy, individual psychology brief psychotherapy, and olanzapine, but its exact mechanism of action is not specified in the available data.

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

Imagine your brain is like a busy city with lots of cars (neurons) moving around. GABA is like a traffic cop that helps slow down the traffic when it gets too busy. Delorazepam helps the traffic cop do its job more effectively, which can help reduce anxiety and promote relaxation.
