简要总结

Obsessive Compulsive Disorder is a highly debilitating condition with a lifetime prevalence of 2%-3%, and a notable percentage of patients (40-60%) have a partial or no response to medications. The present gold standard for the treatment of OCD is medications (Selective serotonin reuptake inhibitors (SSRIs) / Clomipramine) + Exposure and Response Prevention (ERP). There is a significant need for alternative novel methods of treatment. One of the novel methods of treating OCD is using magnetic stimulation which has already been successfully used in the treatment of depression. Treating OCD is difficult with regular superficial repetitive Transcranial Magnetic Stimulation (rTMS) hence the need for coils that targets deeper structures. Thus, we are comparing the efficacy of the two different coils from two different manufacturers plus using ERP in combination with the different coils.

  1. Deep Transcranial Magnetic Stimulation (DTMS) using BrainsWay H7 coil targets deeper structures such as medial prefrontal cortex. The H7 coil has already shown clear evidence in treating patients with OCD and has been approved by the FDA for clinical use.
  2. Repetitive Transcranial Magnetic Stimulation (rTMS) using MagVenture Cool D-B coil could also target the medial prefrontal cortex. Hence it might also be equally effective as the BrainsWay H7 coil in treating patients with OCD.

详细描述

i. Purpose

a) The purpose of this study is to compare and evaluate the efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) by MagVenture and Deep Transcranial Magnetic Stimulation (DTMS) by BrainsWay with and without the combination of active Exposure and Response Prevention (ERP) for the treatment of patients with OCD.

ii. Hypothesis a) We hypothesize that the combination of TMS + active ERP will have a superior efficacy in the treatment of OCD. We also hypothesize that MagVenture cool D-B80 coil will be as effective as BrainsWay H7 coil in treating patients with OCD.

iii. Justification

  1. The Prospective Multicenter Randomized Double-Blind Placebo-Controlled Trial by Carmi et al. (2019) had shown significant improvement in OCD symptoms by using the H7 coil and provocation of OCD symptoms before and during treatment.
  2. The study by Dunlop et al. (2016) has shown reduction in OCD symptom severity by using the Cool D-B80 Coil without provocation.
  3. There have been no head to head studies comparing the BrainsWay H7 coil and MagVenture Cool D-B80 coil using provocation methods for both coils.
  4. Also there have been no head to head studies comparing the gold standard treatment of medications + active ERP with medications + active ERP + TMS and medications + TMS.

结局指标

主要结局

Reduction in the severity of OCD symptoms

时间窗: 8 weeks

- The primary outcome measure is the BOCS and YBOCS severity rating scale. The primary efficacy endpoint is the change in BOCS and YBOCS severity score from baseline to the 8-week visit.

次要结局

  • Clinical Global Impression - Severity (CGI-S) and Improvement (CGI-I) scores.(8-12 weeks)
