Helius Medical Technologies, Inc. Announces Publication of its PoNS™ Registrational Clinical Trial (TBI-001) in TBI

NEWTOWN, Pa., April 30, 2020 (GLOBE NEWSWIRE) — Helius Medical Technologies, Inc. (NASDAQ:HSDT) (TSX:HSM) (“Helius” or the “Company”), a neurotech company focused on neurological wellness, today announced that its registrational clinical trial, TBI-001, was published on April 29, 2020 in Neuromodulation: Technology at the Neural Interface. The TBI-001 trial found that PoNS Treatment™ provided significant improvement in balance in patients with a chronic balance deficit following a mild-to-moderate traumatic brain injury (“mmTBI”).
This newly-published, 122 subject, multicenter, double-blind randomized clinical trial, found that the PoNS Treatment, which pairs translingual neurostimulation using the Portable Neuromodulation Stimulator (PoNS™) device with therapeutic activities, significantly improves balance and gait. Conducted by researchers at 7 clinical sites across the US and Canada, this trial, which was completed in 2017, is the second double-blind, randomized clinical trial to demonstrate the level of balance improvement  PoNS Treatment provides to patients suffering from chronic balance deficit as a result of a mild-to-moderate traumatic brain injury. For more information on the TBI-001 trial and its results, see the published journal article.“Whether traumatic brain injuries are mild, moderate or severe, the devastating effects can last a lifetime,” said Philippe Deschamps, Chief Executive Officer of Helius Medical Technologies. “We are excited to announce the publication of this 122 subject, multicenter, double-blind, randomized, clinical trial in a peer-reviewed journal and believe that it provides important clinical support for the PoNS Treatment as new, novel, valuable treatment  option for patients suffering from the effects of mmTBI.”The PoNS Treatment involves the use of the PoNS device in conjunction with therapeutic activities. The PoNS device sits on the surface of a patient’s tongue and delivers mild, gentle electrical impulses to the surface of the tongue. These impulses excite the neural network flowing to the brain. This neural activity, combined with therapeutic activities, is believed to enable “neuroplasticity” which may restore lost function. The TBI-001 trial evaluated subjects who had experienced a mild-to-moderate traumatic brain injury at least one year prior to receiving the PoNS Treatment and had reached a plateau in recovery (according to their healthcare providers) with physical therapy alone. Subjects used the PoNS device for 5 weeks in conjunction with therapeutic activities. At the end of the 5-week treatment program, patients demonstrated improved balance and gait. Researchers found that 67.2 percent of the pooled patient population who completed 5 weeks of PoNS Treatment experienced a clinically and statistically significant improvement in balance, as indicated in their mean SOT (Sensory Organizational Test) scores at 2 weeks and 5 weeks compared to baseline. Mean DGI (Dynamic Gait Index) scores were significantly increased from baseline at weeks 2 and 5.Exploratory endpoints, such as the headache disability index, sleep quality index and quality of life measure index were also observed as part of the trial. While further analysis and research is needed, there was an indication of improvements in these exploratory endpoints. Demonstrated improvements in balance and gait, coupled with potential improvements in the exploratory endpoints, may allow treated individuals to experience improved quality of life.Mr. Deschamps continued: “We are very encouraged by the results of the clinical trial. As a result of their improvements in balance and gait, many of our patients reported being able to perform independent self-care tasks, like dressing and showering, that were once beyond their reach prior to receiving PoNS Treatment.”Katherine Webb, a patient enrolled in the study described her experience during the study. “It had been 4 and a half years since my injury when I first started the study. For those 4 and a half years, I had not been able to put one foot in tandem in front of the other and walk with my feet in a row without tipping or falling over due to loss of balance. It was early February of 2017, and with the device in my mouth, I walked the line. The Physiotherapist FaceTimed my husband and daughter who were flooded with tears as they watched. As a result of my improved balance throughout the study I experienced many more firsts since my TBI, like washing my hair without having to balance against the shower walls for stability,” said Katherine Webb.About Helius Medical Technologies, Inc.Helius Medical Technologies is a neurotech company focused on neurological wellness.
