Summary

Double arm pivotal study to evaluate the Neurolyser XR as a non-invasive treatment of axial chronic low back pain

Description

Study design: Prospective, Double Arm Timeline: Twelve months enrollment period and 6 months follow-up period. Sites: The study will be conducted at 10 sites in the USA Study population: 80 adult subjects diagnosed with facet related low back pain with an additional 10 roll in subjects.

Arms: 40 patients would be treated by the NeurolyserXR and 40 would get a sham treatment Crossover: blinded crossover between the two arms could be done between 1 and 3 months Primary study objective: Safety and efficacy of the Neurolyser XR for the treatment of chronic low back pain secondary to zygapophyseal joint syndrome.

Safety is measured by the incidence and severity of treatment related adverse events.

Efficacy is measured by pain numerical rating scale

Details
Condition Facet Syndrome of Lumbar Spine
Treatment Sham Procedure, Non-Invasive Thermal Ablation of the Medial Branch Nerves (Neurolyser XR)
