About

The purpose of the present study is to evaluate the safety and efficacy of Brainsway Deep TMS (DTMS) for the treatment of PTSD.

Full description

Deep TMS in conjunction with brief trauma exposure will be compared to sham treatment in conjunction with brief trauma exposure, in a multicenter, randomized, controlled study for the treatment of PTSD. Study duration is 9 weeks, consisting of 4 weeks of treatment and a 5 week and 9 week follow-up visit. Subjects will be randomized to real or sham treatment stratified by site. The design is meant to demonstrate that the device shows superiority compared to sham treatment at the 5 week follow-up visit and at the 9 week follow-up visit, 1 month post-treatment.

Enrollment: 203 patients

Sex: All

Ages: 22 to 68 years old

Volunteers: No Healthy Volunteers

Trial design

Primary purpose: Treatment

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Triple Blind

---

203 participants in 2 patient groups

Sham Treatment

Sham Comparator group

Description:

In the sham treatment,the electrical field induced by the sham coil cannot invoke any action potentials and if no action potentials are induced, then the electric field is insignificant and there is no treatment effect on the brain.

Treatment:

Device: Sham Treatment

Deep TMS System

Experimental group

Description:

Deep Transcranial Magnetic Stimulation (DTMS) is a new form of TMS which allows direct stimulation of deeper neuronal pathways than the standard TMS. The HAC Coil is designed to stimulate neuronal pathways in the medial prefrontal cortex or motor cortex, including the anterior cingulated cortex.

Treatment:

Device: Deep TMS System
