Primary Outcome Measures:
  • PCL-5 Total Score Change [ Time Frame: Through Study Completion (up to 2 years) ]
    The PTSD checklist (PCL-5) will be used to assess PTSD symptom severity pre- and post-treatment. The change in total PCL-5 score from Baseline (Day 0) to endpoint (PT1) compared between active treatment and sham-controlled groups. If a participant does not complete PT1, last observation carried forward (LOCF) will be used. A 50% reduction in scores from Baseline scores to PT1 indicates clinical response to treatment (active sTMS vs. sham), and remission is defined by a post-treatment score below the threshold score published for the PCL-5.


Secondary Outcome Measures:
  • QIDS-SR Total Score Change: Clinical Response [ Time Frame: Through Study Completion (up to 2 years) ]
    The Quick Inventory of Depressive Symptoms-Self Report (QIDS-SR) is a 16 question self-rating assessment of depressive symptom severity. Pre- and post-treatment scores on the QIDS-SR will be analyzed and reported in a descriptive manner for the sample. Categorical response (empirically defined as 50% decrease from pre-treatment baseline) and remission (below threshold score, per published standards for each scale) at endpoint will be calculated and reported.

  • Relationship between Intrinsic Alpha Frequency (IAF) and treatment outcomes [ Time Frame: Through Study Completion (up to 2 years) ]
    TMS will be synchronized to the Individual Alpha Frequency (IAF) of each participant, calculated using electroencephalography (EEG) prior to the first treatment. The relationship between mean IAF at baseline and treatment outcomes (i.e., change in total symptom severity) will be analyzed and reported for both groups, at PT1 and open-label continuation endpoint (OL PT1).

  • Number of Participants with Adverse Event or Unexpected Side Effects: Safety Endpoint [ Time Frame: 2 years ]
    Unexpected side effects and adverse events will be descriptively reported to analyze sTMS safety efficacy. The investigators will follow Institutional Review Board (IRB) guidelines for reporting significant and unexpected adverse events.

Arms Assigned Interventions
Experimental: Active sTMS (NEST-1)

Subjects randomized to this group will receive 20 active synchronized Transcranial Magnetic Stimulation (sTMS) treatments (30 minutes each) over a period of 40 calendar days. Treatment windows will be 10 calendar days to complete 5 active sTMS sessions. Serial assessments will be completed every 5 sessions. Post-treatment (PT1) endpoint assessments will take place on the last day of active sTMS.

Participants that elect to participate in the open-label continuation phase, will receive an additional 20 sTMS treatments (using the NEST-2 device), following the same administration structure as the sham-control series.

Participants will return to complete post-treatment follow-up assessments (PT2) 1 month after their last treatment session (either PT1 or OL PT1).

Device: NEST-1
The NeoSync EEG Synchronized TMS (NEST) is an electromechanical medical device that produces and delivers a sinusoidal magnetic field to areas of the brain in the treatment of PTSD. The device includes an EEG recording module that is used to record individualized alpha frequency (IAF) on randomized personal passport modules (PPM) pre-assigned to be NEST-1 compatible.
Other Names:
  • Active sTMS
  • NeoSync EEG Synchronized TMS
Device: NEST-2
The open-label NeoSync EEG Synchronized TMS (NEST) that produces and delivers a sinusoidal magnetic field to areas of the brain in the treatment of PTSD. The device is distinct in both color and sound both SHAM and NEST-1 devices. PPMs corresponding with both SHAM and NEST-1 devices are compatible with the NEST-2 device.
Other Names:
  • Open-label sTMS
  • NeoSync EEG Synchronized TMS
Sham Comparator: Sham sTMS (SHAM)

Subjects randomized to this group will receive 20 sham synchronized Transcranial Magnetic Stimulation (sTMS) treatments (30 minutes each) over a period of 40 calendar days. Treatment windows will be 10 calendar days to complete 5 sham sessions. Serial assessments will be completed every 5 sessions. Post-treatment (PT1) endpoint assessments will take place immediately after the final sham session.

Participants that elect to participate in the open-label continuation phase, will receive 20 sTMS treatments (using the NEST-2 device), following the same administration structure as the sham-control series.

Participants will return to complete post-treatment follow-up assessments (PT2) 1 month after their last treatment session (either PT1 or OL PT1).

Device: SHAM
The SHAM NeoSync EEG Synchronized TMS (NEST) is a device, identical to the active NEST-1 device, that is configured to simulate the delivery of active treatment without actively delivering sTMS therapy. The device includes an EEG recording module that is used to record individualized alpha frequency (IAF) on randomized personal passport modules (PPM) pre-assigned to be SHAM compatible.
Other Name: NEST-1 Sham Comparator
Device: NEST-2
The open-label NeoSync EEG Synchronized TMS (NEST) that produces and delivers a sinusoidal magnetic field to areas of the brain in the treatment of PTSD. The device is distinct in both color and sound both SHAM and NEST-1 devices. PPMs corresponding with both SHAM and NEST-1 devices are compatible with the NEST-2 device.

Detailed Description:

Posttraumatic stress disorder (PTSD) is a highly prevalent psychiatric disorder associated with high degrees of comorbidity (e.g., major depressive disorder), poor quality of life, and significant social and occupational dysfunction. Currently available evidence-based pharmacological and psychological treatments for PTSD have only modest efficacy, and thus further research is necessary to develop treatment approaches in order to ameliorate the current disparity between disorder impact and prevalence, and effective therapies.

The use of non-invasive neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), in an outpatient setting, has shown to be effective in reducing symptoms in various mental disorders, including PTSD and major depressive disorder (MDD). Research examining the use of rTMS for PTSD still remain limited, the majority of findings pertain to rTMS in MDD cohorts, which excluded individuals with PTSD. Given the high rate of PTSD with MDD comorbidity, additional studies examining this comorbid population are necessary.

Furthermore, rTMS treatment parameters and duration are rather time consuming for patients, requiring that patient travel to an outpatient facility daily, for 6 to 8 weeks, for 30 to 40 minutes each day. This can be an inconvenience and poses an additional burden for individuals that already struggle with societal integration and social/occupational dysfunction. Thus, further exploration and development of non-invasive brain stimulatory devices with the same (or better) effectiveness as rTMS, that can be adapted to be utilized in an at home setting, would revolutionize the treatment of PTSD.

The synchronized transcranial magnetic stimulation (sTMS, NeoSync Inc.) device provides the possibility of the fore mentioned therapeutic development. The sTMS device employs 3 transversely rotating, to deliver low energy, sinusoidal magnetic fields synchronized to an individuals' intrinsic alpha frequency (IAF). Preliminary data has shown that sTMS can effectively reduce depressive symptoms in MDD. Additionally, the investigators' preliminary examination of IAF in participants with comorbid PTSD and depressive symptoms, has illuminated the feasibility of this modality as a treatment approach for PTSD comorbid with MDD.

This study is a prospective, sham-controlled, trial of sTMS delivered to patients who are symptomatic despite ongoing pharmacotherapy for PTSD and mood symptoms. Eligible subjects will be randomized using to receive 4 weeks (5 daily sessions per week) of either sham or active sTMS treatment. Clinical and self-report assessments will be completed at baseline, sham/control series endpoint, and 1 month after the final treatment session. An optional open-label continuation phase will be offered to all study participants who complete the sham-control phase of this study, and additional endpoint assessments will be administered.
