The PRISM Pilot Trial for Post-Traumatic Stress Disorder

Study Overview
=================
Brief Summary
-----------------
A Prospective, Single-Arm, Open-Label Pilot Trial, to Assess Safety and Effectiveness of Process-Instructed Self neuro-Modulation (Prism), as an Adjunct to Standard of Care, in Subjects with Post-Traumatic Stress Disorder (PTSD)

Detailed Description
-----------------
Prism is a software device intended for neurofeedback (NF) training (i.e. operant condition based on EEG signals, also known as EEG-biofeedback), to be used in combination with a standard computer and supported EEG hardware. For purposes of this training, information for feedback is derived and processed from several EEG channels. Prism provides visual and/or auditory signals that correspond to the patient's computed EEG signal, which serves as a surrogate indicator of achieving a state of reduced amygdala activity. The study is a Prospective, Single-Arm, Open-Label Pilot Trial, to Assess Safety and Effectiveness of Process-Instructed Self neuro-Modulation (Prism), as an Adjunct to Standard of Care, in Subjects with Post-Traumatic Stress Disorder (PTSD). The study population will include subjects diagnosed with Post-Traumatic Stress Disorder (PTSD) from 1 year to 20 years after index trauma. The total expected enrollment is up to 100 subjects in one or more sites. The study's primary objective is to assess the safety and effectiveness of fifteen (15) EEG-NF training sessions using the Prism software in reducing PTSD-related symptoms.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Clinician Administered PTSD Scale (CAPS - 5) | The primary objective of this study is to assess the proportion of subjects who demonstrate clinically meaningful improvement in the Clinician Administered PTSD Scale (CAPS - 5) score from Baseline to the 3 months follow-up visit. Clinically meaningful improvement is defined here as a 6-point reduction or more in the CAPS-5 score. | Baseline visit (Week 1) and 3 month Follow-up visit | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| PCL-5 response rate | To assess the proportion of subjects who demonstrate clinically meaningful improvement in the PTSD Checklist for DSM-5 (PCL-5). Clinically meaningful improvement is defined here as a 10-point reduction or more in the PCL-5 score | Baseline visit (Week 1), Post-Intervention Visit (Week 9) and 3 month Follow-up visit | 
| ERQ score | Change from baseline to Month 3 visit in ERQ score | Baseline visit (Week 1), Post-Intervention Visit (Week 9) and 3 month Follow-up visit | 
| PHQ-9 score | Change from baseline to Month 3 visit in PHQ-9 score | Baseline visit (Week 1), Post-Intervention Visit (Week 9) and 3 month Follow-up visit | 
| Clinical Global Impression (CGI) | Change from baseline to Month 3 visit in CGI score | Baseline visit (Week 1), Post-Intervention Visit (Week 9) and 3 month Follow-up visit |
