Preliminary results indicate significant reduction in low back pain with the GLYDER Facet Resurfacing System MINNEAPOLIS, Minn. – January 31, 2013 – Zyga Technology, Inc., a medical device company, today announced that it has completed enrollment in the GLISSADE Trial, a prospective, 40-patient trial that studied the GLYDER® Facet Resurfacing System in the treatment of chronic facetogenic pain. Preliminary data analyses from this five-site trial indicate a significant reduction in pain and improvement in function as measured by Visual Analogue Pain Scale (VAS) and Oswestry Disability Index (ODI). The results of this trial will serve as the foundation for future investigation including the DUET Clinical Trial in Europe and the U.K., and mid-2013 submission for an Investigational Device Exemption (IDE) Study to the U.S. Food and Drug Administration (FDA). The company anticipates CE Marking approval in late 2013. The Centers for Disease Control and Prevention lists low back pain (LBP) as the second most common cause of disability in US adultsi . Ten percent of the U.S. population, over 31 million people, suffer from chronic low back painii . Approximately 31% of chronic low back pain is attributed to the facet jointsiii , small stabilizing joints located between and behind adjacent vertebrae. “For patients suffering from chronic facet pain, there has never been a viable procedure providing long term relief,” said Prof. Dr. Hans Jörg Meisel, Director of the Center of Neurosciences of the BG-Clinic Bergmannstrost Halle, Germany. “Their options were to receive injections several times each year or to undergo a more aggressive, permanent spine fusion procedure. The GLYDER System offers simple, minimally invasive implantation of a device designed to preserve the patient’s anatomy and to provide long-term pain relief. Our initial patients are now reaching two years post-surgery, and we are very encouraged to see that they are experiencing sustainable pain relief.” “We are very encouraged by the preliminary results in the GLISSADE Trial, and the available data suggest the GLYDER System’s clinical and economic value,” said Jim Bullock, president and chief executive officer of Zyga Technology. “Facet joint injections have risen steadily over the past decade. This study has indicated how GLYDER Facet Resurfacing provides a safe, appropriate, clinically effective treatment for facetogenic pain and will pave the way for a successful IDE submission later in the second quarter of this year.” Zyga Technology, Inc. 700 10t.
