On virtually all key measures of effectiveness, the 2-year data showed improvements over the 1-year patient visit data. To note :

Dr. Chris Gilligan, director of the Brigham and Women’s Spine Center at Brigham and Women’s Hospital and assistant professor of anesthesia at Harvard Medical School, said: ” Recently published data from the ReActiv8-B clinical trial showed clinically significant improvements in pain and function in patients with refractory chronic low back pain who received two years of neurostimulation. Patient pain scores have significantly decreased from an average of 7.3 to 2.4 and are maintained for 2+ years with ongoing data collection. These long-term data are extremely important and encouraging given the chronic and refractory nature of this condition.
“These impressive results represent an important milestone for Mainstay, as the profound improvements in patient outcomes we have seen from baseline through 1 to 2 years validate the restorative nature of the therapy and represent a new paradigm among treatments. available for patients with chronic incurable low back pain,notedJason Hannon, CEO of Mainstay Medical. “We are proud to have the only commercially available device with a strong safety profile and long-term peer-reviewed evidence supporting rehabilitation in this severely affected patient population, evidence that continues to expand to through multiple clinical trials.

About ReActiv8®
ReActiv8 is an implantable medical device designed to treat adults with chronic intractable low back pain (CLBP) associated with multifidus muscle dysfunction. Multifidus muscle dysfunction may be demonstrated by imaging or physiological testing in adults who have failed treatment, including pain medications and physical therapy, and who are not candidates for spinal surgery. ReActiv8 has received regulatory approval in multiple geographies and is commercially available in the European Economic Area, Australia, the United Kingdom and the United States.
About the ReActiv8-B clinical trial
The ReActiv8-B clinical trial is an international, multicenter, prospective, randomized, active simulation-controlled, blinded, one-way crossover trial conducted under an investigational device exemption (IDE) from the FDA. A total of 204 patients with chronic low back pain refractory to physiotherapy and medical management were implanted with ReActiv8 at leading clinical sites in the United States, Europe and Australia and randomized 1:1 for treatment or a control. In the treatment group, the ReActiv8 pulse generator was programmed to deliver electrical stimulation believed to cause episodic contractions of the multifidus muscle. In the control group, the ReActiv8 device was programmed to provide a low level of electrical stimulation. Following assessment of the primary endpoint at 120 days, patients in the control group were switched to receive similar levels of electrical stimulation as the treatment group.
Clinical trial funded by Mainstay Medical. Dr. Chris Gilligan, principal investigator of the trial, is a consultant to Mainstay Medical. Information about the study is available at https://clinicaltrials.gov/ct2/show/study/NCT02577354.
