rTMS Device for Improvement of Obsessive and Compulsive Behaviors

Official title

Evaluation of the Efficacy and Safety of an Accelerated Protocol for Obsessive and Compulsive Behaviour Using the BTL-699-2 Device

Overview

The goal of this investigational study is to evaluate if the treatment using EXOMIND(BTL-699-2) device is able to improve severity of obsessive and compulsive symptoms in adults (aged 22 and older). The main question it aims to answer is: Does the treatment using EXOMIND (BTL-699-2) device is able safely and efficiently reduce the severity of obsessive and compulsive behaviors? Participants will be asked to: * Complete six treatment visits (twelve treatment sessions) * Complete The Yale-Brown Obsessive-Compulsive Severity Scale Second Edition Self Report Version (Y-BOCS-II SR) * Complete Short UPPS-P Impulsive Behaviour Scale (SUPPS-P) * Compete The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS) * Compete The Patient Health Questionnaire-9 (PHQ-9) * Compete Columbia Suicide Severity Rating Scale -screen version(CSSRS) * Complete Trigger Recall Experience Questionnaire (only for participants who agree to participate in trigger recall procedure during the treatment sessions) * Compete The Therapy Comfort Questionnaire * Compete The Subject Satisfaction Questionnaire

Detailed description

This is a prospective, interventional, multi-centre, single-blinded, two-arm study. The subjects will be enrolled and randomly assigned to two experimental study arms: the active group (Group A) and the sham group (Group B), in a ratio of 3:1. All enrolled participants will be treated (either active or sham) with the BTL-699-2 device. Group A will receive active treatment (BTL-699-2 with intensity up to 80% of the individual's motor threshold (MT), and Group B will receive sham treatment (BTL-699-2 with intensity of 5% of the individual's MT).

The Yale-Brown Obsessive-Compulsive Severity Scale Second Edition Self Report Version (Y-BOCS-II SR), Short UPPS-P Impulsive Behavior Scale (SUPPS-P), The Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), Columbia Suicide Severity Rating Scale -screen version(CSSRS) and the urinary pregnancy test will be given to the subjects at baseline, at the last treatment visit, at the 1-month and at 3-month follow-up visits. The Patient Health Questionnaire-9 (PHQ-9) will be administered at baseline, after the second, fourth, and last treatment visits, at the 1-month and 3-month follow-up visits. The Trigger Recall Experience Questionnaire (TREQ) will be conducted at the end of each treatment session only for participants who voluntarily choose to engage in trigger recall procedure. Therapy Comfort questionnaires will be given to the subjects after the last treatment. Subject Satisfaction Questionnaire will be given to the subjects after the last treatment, and at both 1-month and 3-month follow-ups.

The approximate subject participation duration is six (6) months after the enrollment.

Interventions

• Device EXOMIND (BTL-699-2) Active treatment
  Participants will receive twelve transcranial magnetic stimulation treatment sessions during 6 treatment visits (each treatment visit will include two treatment sessions) with the BTL-699-2 device over the left dorsomedial prefrontal cortex. The intensity will be adjusted according to the subject's feedback, up to 80% of the individual's motor threshold. The treatment visits will be spaced 2 - 4 days apart.
• Device EXOMIND (BTL-699-2) Sham treatment
  Participants will receive twelve transcranial magnetic stimulation treatment sessions during 6 treatment visits (each treatment visit will include two treatment sessions) with the BTL-699-2 device over the left dorsomedial prefrontal cortex. The intensity will be set to 5% of the individual's motor threshold. The treatment visits will be spaced 2 - 4 days apart.

Eligibility criteria

Inclusion criteria

• Age 22 years and older
• Voluntarily signed an informed consent form
• Current presence of obsessive-compulsive behaviors of at least mild severity, defined as a Y-BOCS-II Self-Report total score ≥15.
• Subjects willing and able to abstain from partaking in any treatments other than the pre-procedure therapy regime for the treatment of obsessive-compulsive behaviours, including non-invasive brain stimulation treatments other than the study procedure during study participation
• Ability to determine the motor threshold of the participant. The participant's motor threshold could be established as the minimum stimulus required to induce contraction of the right thumb.
• If applicable, subjects will be maintained on pre-study psychotherapeutic regime, and neuropsychiatric prescribed medications (including SSRI or other medication, except for more than 2mg of lorazepam or equivalent) at a stable therapeutic dosage for at least 2 months prior to study entry
• Women of child-bearing potential\* are required to use birth control measures during the whole duration of the study
• Willingness to comply with study instructions and to return to the clinic for the required visits \*Women of childbearing potential are defined as any female who has experienced menarche and who is NOT permanently sterile or postmenopausal. Postmenopausal is defined as 12 consecutive months with no menses without an alternative medical cause.
