Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to test the safety and efficacy of repeated doses of ketamine as compared to placebo to reduce symptoms of Posttraumatic Stress Disorder (PTSD) among Veteran receiving Prolonged Exposure Therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

In this single site clinical trial, intended to evaluate the safety and efficacy of repeated doses of ketamine in conjunction with prolonged exposure (PE) therapy for PTSD. Veterans who meet criteria for PTSD and the additional inclusion and exclusion criteria will be randomized to one of two treatment arms (placebo plus PE vs ketamine plus PE). Participants receive the study drug via intravenous infusion once per week for 3-weeks.

Participants Caregivers Investigators Outcome Assessors
The investigators will use a sequentially numbered, opaque, sealed envelopes, pharmacy-controlled allocations, and coded identical containers for adequate concealment allocation. Administration of study drugs and infusion monitoring will be conducted by research nurse keeping blinding from investigators and independent outcome assessors.
