|Official Title:||A Prospective Double Blind Randomized Controlled Trial to Evaluate the Safety and Efficacy of the Deep Transcranial Magnetic Stimulation (dTMS) in Obsessive-Compulsive Subjects|
|Study Start Date :||September 2014|
|Actual Primary Completion Date :||June 2017|

Active Comparator: Active DTMS Treatment
Active DTMS Treatment constitutes the Deep Transcranial Magnetci Stimulation (DTMS) which is a new form of TMS which allows direct stimulation of deeper neruonal pathways than the standard TMS. The DTMS coil is designed to allow deeper brain stimulation without significant increase of electric fields included in superficial cortical regions.
Device: Active DTMS Treatment
H-coil Deep TMS 29 TMS treatments over 6 weeks.
Sham Comparator: Sham Treatment
The Sham Treatment consists of an electrical field which cannot invoke any action potentials and if no action potentials are induced, then the electric field is insignificant and there is no treatment effect on the brain.
Device: Sham Treatment
29 treatments over 6 weeks.
Other Name: Deep TMS Sham treatment
- Yale Brown Obsessive Compulsive Scale (YBOCS) score [ Time Frame: 6 Weeks ]The primary objective of the study is to compare the change in Yale Brown Obsessive Compulsive Scale (YBOCS) scores from baseline to the 6 week (post-randomization) visit, between the two treatments groups.
- Yale Brown Obsessive Compulsive Scale (YBOCS), Sheehan Disability Scale (SDS), Clinical Global Impression - Severity Scale (CGI-S), Clinical Global Impression - Improvement Scale (CGI-I) [ Time Frame: 6 Weeks and 10 weeks ]
The secondary effectiveness objectives of the study are:
i. Change from baseline to 6 weeks in Yale Brown Obsessive Compulsive Scale (YBOCS) (and other assessment scale) scores, between treatment groups.
ii. Response rate at 6 weeks in Yale Brown Obsessive Compulsive Scale (YBOCS) score from baseline, between treatment groups; iii.Partial Response rate at 6 weeks in Yale Brown Obsessive Compulsive Scale (YBOCS) score, between treatment groups; iv. Change from baseline to 10 weeks in above scales. v. Remission rates at 6 weeks between treatment groups.
- Number of adverse events, changes in vitals signs, physical and neurological results, changes in suicide scale and changes in cognitive scales [ Time Frame: 10 Weeks ]
Safety of the DTMS treatment as defined by maintained subject baseline, pre-treatment, physical and neurological examinations and lack of significant increase in suicide ideation measured by:
- Vital signs
- Physical and neurological examination
- Scale for Suicide Ideation
- Cognitive evaluation using the Mini-Mental State Exam (MMSE), Buschke Selective Reminding Test (BSRT) and Autobiographical Memory Interview - Short Form (AMI-S) scales
- Any other adverse events (AEs).
