Lu AG06466 in Participants With Post Traumatic Stress Disorder (PTSD)

Phase 1
Completed
Conditions
PTSD
Interventions
Drug: Placebo
Drug: Lu AG06466
Registration Number
NCT04597450
Lead Sponsor
H. Lundbeck A/S
Brief Summary

The purpose of this study is to investigate the effect of Lu AG06466 after multiple doses of 30 milligrams (mg) in participants with PTSD.

Detailed Description

The crossover study consists of two treatment periods of 15 days duration. On Day -1 or Day 1 of Treatment Period 1, eligible participants will be randomized (1:1) to a sequence of treatments (either Lu AG06466-placebo or placebo-Lu AG06466) with 15 participants are planned per sequence. Each treatment period will be separated by a washout period of ≥7 and ≤14 days.
