New Data Published in American Journal of Psychiatry Further Substantiates BrainsWay’s Deep TMS System for the Treatment of Patients with Obsessive Compulsive Disorder

First non-invasive device for OCD achieves 45% response rate among patients after one month follow up, and significantly reduced symptoms scores compared with placebo

HACKENSACK, N.J., June 27, 2019 (GLOBE NEWSWIRE) — BrainsWay Ltd. (NASDAQ: BWAY, TASE: BWAY), a global leader in the advanced, non-invasive treatment of brain disorders, today announced new data from an article published in the last issue of the American Journal of Psychiatry demonstrating that its Deep TMS™ System showed a significant clinical benefit compared with placebo to treat Obsessive Compulsive Disorder (OCD) in a ~100-patient clinical trial (NCT02229903). OCD is a chronic and disabling disorder that affects ~1% of US adults. BrainsWay’s Deep TMS OCD treatment received De Novo clearance from the U.S. Food and Drug Administration (FDA) in August 2018 and is the only TMS platform that is FDA-cleared to treat OCD.

BrainsWay’s Deep TMS system provides OCD patients with a non-invasive, personalized treatment option that augments existing therapeutic approaches, including pharmacological or psychological therapy.  “We need new treatment options for OCD because current psychological therapies and medications often yield unsatisfactory results,” said David Feifel MD, PhD, Professor Emeritus of Psychiatry at the University of California, San Diego, Director of Kadima Neuropsychiatry Institute and an investigator in the study. “The results of this clinical study demonstrate that Deep TMS performed daily for six weeks can significantly improve OCD symptoms and is safe and well-tolerated. It is particularly impressive that the improvement in symptoms was comparable to the average improvement we often see with a standard course of medications alone for 12 weeks, but was produced in half the time, and with fewer side effects. Importantly, these improvements lasted for at least a month after the treatment was stopped. Patients in the study all had moderate to severe OCD symptoms despite taking medications for OCD. These results suggest that this innovative, non-invasive and personalized adjunct approach can provide a measurable benefit to those OCD patients who continue to struggle with debilitating symptoms despite receiving the best available drug treatments.”

About The Study

The data published in the American Journal of Psychiatry are from a double-blind, placebo-controlled, multicenter, FDA-regulated clinical trial that compared the effects of high-frequency (20Hz) Deep TMS to that of sham treatment (placebo) administered daily for six weeks on patients with OCD symptoms as assessed using the Yale-Brown-Obsessive-Compulsive-Scale (Y-BOCS).

The primary efficacy endpoint was the change in Y-BOCS scale from baseline to post-treatment. Secondary efficacy endpoints were the proportion of patients who achieved full response and partial response, defined as 30% or 20% reduction, respectively, in Y-BOCS scores from baseline to post-treatment, changes at follow-up four weeks post-treatment, and other scales listed below.

The trial was conducted at 11 clinical centers, among OCD patients who had inadequate responses to pharmacological therapy with serotonin reuptake inhibitors (SRIs) or who failed or had inadequate responses to cognitive behavioral therapy (CBT). Deep TMS treatment was given as an adjunct therapy in addition to the patients’ current method of treatment whether pharmacological or CBT. Prior to each treatment session, patients underwent a 3-5 minute individualized symptom provocation in order to activate their OCD circuitry. A total of 94 patients who received at least one active/placebo treatment and met the study eligibility criteria were included in the FDA-approved main analysis set.

Key findings from the study include:

• There was a significantly greater reduction in Y-BOCS scores in patients treated with Deep TMS compared with placebo (-6.0 points vs. -3.3 points, p=0.01) for an effect size of 0.69 following six weeks of daily treatment. This benefit was maintained at one-month follow-up, with Y-BOCS reductions of -6.5 and -4.1 points for the Deep TMS and placebo groups, respectively (p=0.03) for an effect size of 0.62.
• The full response rate (Y-BOCS reduction ≥30%) at the end of treatment was significantly higher in the Deep TMS group (38.1%) compared with the placebo group (11.1%), p=0.003. This improvement was also maintained at one-month follow-up (45.2% vs. 17.8%, respectively, p=0.0057).
• The partial response rate (Y-BOCS reduction ≥20%) at the end of treatment was significantly higher in the Deep TMS group (54.8%) compared with the placebo group (26.7%), p=0.0076. This improvement was also maintained at one-month follow-up (59.5% vs. 42.2%, respectively), although this later difference was not statistically significant (p=0.1059).
• The clinicians’ global impression of improvement (CGI-I), a measure of global improvement functioning, was statistically different between the active Deep TMS group, with 49% being assessed as moderate to very much globally improved compared to 21% of the sham group (p=0.011).
• The change from baseline in the clinicians’ global impression of severity (CGI-S), a measure of global severity of functioning, was found to be statistically significant at the post-treatment assessment, with 61% of Deep TMS subjects demonstrating improvement, compared to 32.6% of sham (p=0.022).
• There was no statistically significant difference in the numbers and types of adverse events in the Deep TMS and placebo groups. Typical to TMS studies, headache was the most common adverse event in both the Deep TMS and placebo groups (37.5% and 35.3%, respectively) and was not significantly different between the groups.
• There were no significant adverse events reported due to the Deep TMS treatment.
• There was no significant difference in the dropout rate between the Deep TMS and placebo groups (10% each).

“The mechanism of action of this treatment is quite different from that of current medications,” said Prof. Abraham Zangen, a scientific founder and a neurobiological consultant for BrainsWay. “The brain region targeted in this pivotal trial with the Deep TMS H7 coil is the anterior cingulate cortex, a region known for decades to be centrally implicated in the pathophysiology of OCD. Modulation of the relevant neural networks by Deep TMS following an individualized psychological provocation procedure, which is part of the treatment protocol, allows a gradual and stable neuroplastic change – resulting in an effective treatment for millions of OCD patients who do not sufficiently respond to medications or psychotherapies.”

The authors of the paper also refer to a recent meta-analysis of 17 studies demonstrating that SRIs were superior to placebo for OCD with an average 3.2 points weighted mean difference on the YBOCS after 10-13 weeks of treatment. This Deep TMS study recruited patients who were moderately to severely symptomatic (mean YBOC=28) despite being treated with medications, and in many cases, also psychotherapy. They improved within six weeks of treatment using Deep TMS as an adjunct therapy, and their improvement continued even after they completed their six weeks of treatment.

“The positive results seen in this population of patients, who have not sufficiently benefited from SRIs or CBT, further validate Deep TMS as a uniquely effective treatment option,” said Yaacov Michlin, CEO of BrainsWay. “The study authors suggest that Deep TMS should be considered at the early stages of treatment if patients fail to have an adequate response to appropriate psychological or pharmacological therapy. We believe this data and the authors’ conclusions add to the growing body of evidence supporting the use of Deep TMS as a standard adjunct component of OCD therapy.”

About OCD

More than 2 million adults in the United States suffer from obsessive-compulsive disorder (OCD). It is a severe, chronic psychiatric disease characterized by a pattern of obsessive thoughts and compulsive repetitive behaviors, which has a significantly destructive effect on patients’ day-to-day activities. Current treatment options include SSRI antidepressant medications, which must be given at very high doses for OCD patients, cognitive-behavioral therapy (CBT), or a combination of these treatment options. OCD is very difficult to treat since many patients do not respond to medication or CBT, and many have difficulty tolerating the side effects of pharmacological treatment.
