Helius Medical Technologies, Inc. medical technology company focused on the treatment of neurological symptoms caused by disease or trauma, announced today that the Multiple Sclerosis (“MS”) pilot study evaluating its investigational Portable Neuromodulation Stimulator (“PoNS™”) device, met all of its study objectives. A total of 14 subjects (7-active and 7-sham control) received treatment with the non-invasive brain stimulation technology and concomitant physiotherapy. The independent trial took place at the Montreal Neurological Institute and Hospital and Concordia University’s PERFORM Center. The study objectives were to explore the potential beneficial effects of PoNSTM stimulation, as previously reported, and to provide data to be used for the design of future studies to support requests for marketing authorization. The study included the first use of Functional MRI (“fMRI”) to measure the effect of PoNSTM while performing tasks with, and without, stimulation.
About the PoNS™
The PoNS™ device is a non-invasive means for delivering neurostimulation through the tongue. The PoNS™ therapy is currently being studied in the United States for the treatment of balance disorder for subjects with mild to moderate Traumatic Brain Injury (“mTBI”), and in Canada for the treatment of gait and balance disorder for subjects with MS.
The PoNS™ device is believed to be the first non-invasive means for delivering neurostimulation through the tongue. Researchers believe that use of the tongue as a gateway to the brain may be one of the most natural, non-invasive and direct ways to stimulate the brain. The tongue is anatomically unique, being richly innervated by thousands of nerve fibers and interconnected to the brainstem by two major cranial nerves.
“Measuring brain activity and the changes taking place through fMRI is designed to determine in an objective way if, in fact, there are indications of neuroplastic change in the brain.”
- fMRI measured the effect of PoNSTM neurostimulation while performing working memory and mental imagery tasks. Results suggest that the PoNSTM device may be facilitating neural plasticity.
- fMRI results were significantly different between the Active Group (who manifested brain function comparable to healthy subjects following treatment) and the control group. (p<0.02).
- The PoNSTM stimulation group showed a statistically significant improvement (p<.001 in balance as measured by the Sensory Organization Test (SOT) scores, which were compared at baseline and week 14. The change in the control group did not reach the same level of statistical significance (p >.05).
There was a good safety profile for the PoNSTM device reported in the study. Factors to improve recruitment, screening, randomization and execution were identified and will be considered in the design of future MS studies. The results included a power analysis suggesting a sample size of 128 subjects (64 active, 64-sham) would be suitable for a definitive MS study.
“We are delighted with the findings that are consistent with prior studies. The fMRI data show that the PoNSTM may be changing the way the brain functions,” said Helius’ Chief Medical Officer, Dr. Jonathan Sackier. “Measuring brain activity and the changes taking place through fMRI is designed to determine in an objective way if, in fact, there are indications of neuroplastic change in the brain.”
“This is an exciting and promising development for our company, patients and the healthcare community. Addressing symptoms caused by MS has been a challenge for the medical community and we are excited to pursue PoNSTM as a potential therapeutic tool”, said Helius’ CEO, Philippe Deschamps. “We reached all the objectives of this study and are optimistic as we continue to advance the PoNSTM device through clinical trials.”
“The researchers from the Montreal Neurological Institute and Hospital are pleased with the execution of this study and are excited by the results as they point to a new frontier in research in brain injury rehabilitation. We are happy to be on the forefront of research that may bring this technology to patients in need,” said Dr. Gabriel Leonard, Principal Investigator for the study. Dr. Yves Lapierre and Dr. Alain Ptito from the Montreal Neurological Institute and Hospital joined Dr. Leonard as investigators in the study.
Helius would like to thank the study investigators Doctors Leonard, Ptito, and Lapierre, as well as study staff, subjects and founding scientists. The investigators and sponsor intend to submit study results for publication.
