DenerveX System Demonstrates Clinical Benefits in Patients Suffering from Low Back Facet Joint Pain

Medovex Corp., developer of the DenerveX System, has released patient data that demonstrates clinical benefits of its DenerveX System in patients suffering from low back facet joint pain at six months post-treatment.
 
Facet Joint Syndrome (FJS) is among the leading causes of low back pain and affects millions of people globally. Typically manifesting from spinal osteoarthritis (OA), FJS is a painful, chronic condition whose treatment options, often temporary in nature, have remained unchanged in the past four decades.
 
Medovex’s DenerveX is a minimally invasive system developed to provide potential long-term relief via a combination of controlled thermal energy and rotational capsular tissue shaving of the bony structure to disrupt nociceptive signals and receptors. The company hypothesized that use of this novel system would result in sustained pain relief and improved health metrics associated with mobility.
 
The prospective multicenter European cohort included patients with chronic intractable pain of the low back resulting from FJS who had failed conservative treatments for pain. Patients who were treated between July 2017 and February 2018 were evaluated for joint groupings treated, pain and quality of life as measured by the visual analog score (VAS), medication log, Oswestry Disability Index (ODI) and EQ-5D-5L. Follow-up was conducted at one, three, and six months post-treatment; data reported correspond to these time points.
 
Results from 61 patients (60.7 percent females; average age 55.1 ±11.5 years) were evaluated. Prior to treatment, 47 patients regularly used one or more prescribed analgesics and had predominately undergone either physiotherapy (81.4 percent), spinal injections (86.4 percent), or both to help alleviate pain. A total of seven joint groupings were treated, with L3 – S1 (45.6 percent) and L4 – L5 (17.5 percent) being the most common. Baseline average VASback prior to treatment was 74.7 ±14.2mm; a 42 ±16.6 ODI score with a EQ-5D-5L score of 3 (out of 5). At one, three, and six months post-treatment, VASback decreased to 31.7 ±17.5mm (-57.5 percent), 25.5 ±22.9mm (-65.8 percent), and 17.7 ±18.3mm (-76.3 percent). Similarly, ODI one, three, and six months post-treatment decreased to 19.9 ±14.4 (-52.7 percent), 20.1 ±15 (-52.3 percent), and 14.1 ±9.9 (-66.4 percent). These decreases from baseline were consistently observed in more than half of the population. EQ-5D-5L scores post-treatment remained, on average 32 percent below baseline values.
 
Review of real world cases from five independent sites across Europe demonstrated reduction in pain scores and general improvement of health metrics up to six months following treatment as evidenced by VASBACK, ODI and EQ-5D-5L.
 
Jill Schweiger, Medovex senior vice president of Regulatory, Clinical and Quality, stated, “We are pleased to present these initial results which affirm our belief that the DenerveX System provides significant quality of life improvement and relief from pain associated with facet joint syndrome. We look forward to releasing one-year data as soon as it is available.”
 
After successful INVIMA product approval in Colombia, first DenerveX cases are scheduled for July 14 in Medellin followed by additional cases in Bogota and other areas throughout Colombia.
 
In April, the company was issued two U.S. patents and a trademark covering the EU for “Rotacapsulation.”

• Patent No: U.S. D810,290S Surgical Portal Driver
• Patent No: U.S. 9,883,882 Minimally Invasive Methods for Spinal Facet Therapy to alleviate pain and associated surgical tools, kits and instructional media

 
Medovex was formed to acquire and develop a diversified portfolio of potentially groundbreaking medical technology products. Criteria for selection include those products with potential for significant improvement in the quality of patient care combined with cost effectiveness. The company’s first pipeline product, the DenerveX System, is intended to provide long lasting relief from pain associated with facet joint syndrome.
