A key step towards European commercialisation of innovative treatment of chronic low back pain
Dublin, Ireland – Mainstay Medical International plc (Mainstay or the Company, Euronext Paris: MSTY.PA and ESM of the Irish Stock Exchange: MSTY.IE), a medical device company focused on bringing to market ReActiv8®, an implantable neurostimulation system to treat disabling Chronic Low Back Pain, announces it has submitted an application for CE Mark for ReActiv8. The submission represents a further key step towards commercialisation of ReActiv8 in Europe.
Mainstay’s application for CE Mark includes the results of the ReActiv8-A Clinical Trial which showed clinically important, statistically significant, and lasting improvement in pain, disability, and quality of life for people with Chronic Low Back Pain and limited treatment options1.
Peter Crosby, CEO of Mainstay, said: “The application for CE Mark approval is a significant milestone for Mainstay and follows the successful results of our ReActiv8-A trial. With FDA approval to start the ReActiv8-B Clinical Trial to gather data for an application for US approval, we are moving towards our goal of commercialisation of ReActiv8 in major world markets. We believe ReActiv8 has the potential to change the lives of millions of people who have no effective treatment for their chronic low back pain and we are now a step closer to selling ReActiv8 in Europe.”
ReActiv8-A (http://clinicaltrials.gov/show/NCT01985230) is an international, multi-centre, prospective single arm clinical trial that recruited subjects who were not candidates indicated for surgery or spinal cord stimulation, and who had attempted other therapies, including at least physical therapy.
Data have been reported for the first 46 subjects in the ReActiv8-A trial. After 90 days of treatment with ReActiv8, 63% of people showed a clinically important improvement in their low back pain, 57% showed a clinically important improvement in their disability and 67% showed a clinically important improvement in their quality of life. Improvements in low back pain, disability and quality of life were generally consistent or improved at 180 days.
In addition to the clinical results, the application for CE Mark includes extensive information about the design, testing, manufacturing, and quality system for ReActiv8, and is the culmination of several years’ work.
Mainstay’s notified body will review the application for CE Mark, and Mainstay will respond to questions and/or requests for additional data during the review process.
Mainstay Medical plans to establish its own direct sales force for commercialisation of ReActiv8 in key European markets starting in 2016, subject to CE Mark approval.

CE Marking
CE Marking is a mandatory conformity marking for certain products sold within the European Economic Area since 1985, and is a declaration that the product meets the essential requirements of the applicable EC directives. For Active Implantable Medical Devices (AIMDs) like ReActiv8, CE Marking is granted by a Notified Body after review of the design dossier and other information for conformity to the AIMD Directive. Following CE Marking, a product can be sold in the EEA, and certain other countries.
About Mainstay
Mainstay is a medical device company which is developing an innovative implantable neurostimulation system, ReActiv8®, for people with disabling Chronic Low Back Pain (CLBP). The Company is headquartered in Dublin, Ireland. It has subsidiaries operating in Ireland, the United States and Australia, and is listed on Euronext Paris (MSTY.PA) and the ESM of the Irish Stock Exchange (MSTY.IE).
About Chronic Low Back Pain
One of the recognised root causes of CLBP is impaired control by the nervous system of the muscles that dynamically stabilise the spine in the lower back, and an unstable spine can lead to back pain. ReActiv8 is designed to electrically stimulate the nerves responsible for contracting these muscles and thereby help to restore muscle control and improve dynamic spine stability, allowing the body to recover from CLBP.
People with CLBP usually have a greatly reduced quality of life and score significantly higher on scales for pain, disability, depression, anxiety and sleep disorders. Their pain and disability can persist despite the best available medical treatments, and only a small percentage of cases result from an identified pathological condition or anatomical defect that may be correctable with spine surgery. Their ability to work or be productive is seriously affected by the condition and the resulting days lost from work, disability benefits and health resource utilisation put a significant burden on individuals, families, communities, industry, and governments.
