Clinical Trial to Evaluate the Safety and Efficacy of MeRT Treatment in Post-Traumatic Stress Disorder

MERT-005-B is a prospective, double blind, randomized, sham-controlled, parallel group, stratified, adaptive clinical trial designed to evaluate the efficacy of EEG-guided MeRT in persons with Post-Traumatic Stress Disorder A total of 152 participants will be randomized in the Test Phase, and a group-sequential approach to efficacy monitoring by the Data and Safety Monitoring Board (DSMB). A Pilot Phase was completed in which 74 participants were randomized. The Pilot Phase data will be used for confirming the safety of MeRT. For the Test Phase, eligible participants will be randomly assigned to either MeRT or Sham MeRT treatment groups in a 1:1 allocation ratio, with stratification on recruitment site and two levels of PPCS co-morbidity (+/-). Initial eligibility evaluation and data collection will occur at the Screening Visit (SC). Following the SC visit, there will be a 5-week treatment period in which active or sham investigative treatment will be administered during daily weekday visits to the study site. Participants who received sham treatment and who continue to be eligible will be offered up to 25 active MeRT study treatments as part of Open Label Enrollment. Main study outcomes will be collected at the second follow-up visit (F2) at the conclusion of the 5-week treatment period. An abbreviated data collection visit will occur during the third treatment week (the F1 follow-up visit). Additional follow up visits will occur 90 days after the first day of study treatment. Participants, clinicians, and all personnel who participate in evaluation will be blind to study treatment group assignment. The first phase of this trial was conducted in partnership with the United States Special Operations Command (USSOCOM) and the Henry Jackson Foundation.
