Clinical Trial 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)

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.

Exclusion Criteria:

1. Have completed two or more full courses of trauma-focused therapy in the past (i.e., EMDR, Prolong Exposure Therapy, etc.), eligibility will be deemed upon the clinical judgment of the investigator.

2. Lifetime diagnosis for schizophrenia, schizoaffective disorder, schizophreniform disorder, Bipolar I disorder, or delusional disorder

3. Any mood disorder and anxiety disorder according to DSM-5 (in addition to those described in Exclusion 2) that is the primary focus of treatment in the last 6 months prior to screening, as per the clinical judgment of the investigator

5. Diagnosis of moderate or severe substance use disorder within the last 3 months of screening visit (as defined in DSM-5-substance use disorder) or at screening visit

6. Any prescribed Benzodiazepine which cannot be ceased for the duration of the study (with a washout period of at least 2 weeks prior to the first Prism training session) or which cannot be replaced with short-acting benzodiazepines that are taken only for sleeping during the night

7. Any psychotropic medication other than a stable dose of selective serotonin reuptake inhibitors (SSRIs) or serotonin-norepinephrine reuptake inhibitor (SNRIs)

8. Any change in or initiation of- SSRIs or SNRIs antidepressants within the past 4 weeks. At the time of recruitment, subjects must have no intention of changing their medication or psychotherapy during the study duration

9. Any suicidal behavior in the past 1 year (i.e. actual attempt, interrupted attempt, aborted attempt, or preparatory acts or behavior) prior to screening and during the screening period

12. Any unstable medical condition, as per the clinical judgement of the investigator

13. In process of establishing/changing governmental/institutional compensation payments for PTSD symptoms

14. Enrollment in another clinical study at screening or within 2 months prior to screening, or intended enrollment within the duration of this study

15. Women who are pregnant, nursing, or who plan to become pregnant while in the trial

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Abbreviated PCL (APCL)	To assess the change in the score of the abbreviated PCL scale (APCL, assessed weekly during the EFP-NF training period)	through study completion, an average of 8 weeks
Other	learning success of the EFP-based neurofeedback	To quantify the learning success of the EFP-based neurofeedback (namely: learning volitional down-regulation of the Amyg-EFP signal, over time, during the EFP-NF training period)	through study completion, an average of 8 weeks
Other	Patient satisfaction survey	To quantify patient satisfaction from the EFP-NF training using survey	through study completion, an average of 5 month
Other	Remission rate	To assess the Remission rate at post training visit (8-9 weeks) and at the 3 months follow-up visit	Baseline visit (Week 1), Post-Intervention Visit (Week 9) and 3 month Follow-up visit
