Further real-world evidence supporting the efficacy and use of ReActiv8® Restorative NeurostimulationTM for the treatment of intractable Chronic Low Back Pain
Mainstay Medical Holdings plc today announced the publication of three-year clinical data from the Post-Market Clinical Follow-up (PMCF) study of 33 ReActiv8 patients from five medical centres across the United Kingdom. The three-year results, published in British Journal of Pain, demonstrated that a substantial portion of patients experienced statistically significant improvements in measures of pain (NRS), disability (ODI) and quality of life (EQ-5D-5L). The publication can be found here: https://journals.sagepub.com/doi/10.1177/20494637231181498.
These results indicate that the response to ReActiv8 for these patients is durable and improves over time, validating ReActiv8’s restorative mechanism of action. In addition, these real-world outcomes are consistent with the three-year data from the pivotal ReActiv8-B clinical trial, announced in September 2022, as shown in the following table:
Dr. Simon Thomson MBBS FFPMRCA, Consultant Lead at the Pain and Neuromodulation Centre, Mid and South Essex University Hospitals NHS, Essex, UK, stated: “These results demonstrate durability and safety of this therapy in chronic back pain sufferers who would have continued to be crippled and dominated by their symptoms but for ReActiv8. These patients, drawn from usual UK Pain clinics, are now as good as those seen in the continuation cohort from the more highly selected randomised ReActiv8-B trial.”
Jason Hannon, CEO of Mainstay Medical, stated: “We are pleased to add these compelling results to the growing global body of positive peer-reviewed evidence supporting the ability of ReActiv8 to provide positive long-term outcomes to this severely affected patient population. Most importantly, the continued improvement in patient outcomes observed in the real-world setting is consistent with the results from our controlled clinical trials.”
