SPRINT’s 60-day Treatment May Eliminate Need for Permanent Implant

The double-blinded, randomized controlled study was awarded “Best of Meeting” at the 18th Annual Meeting of the American Society of Regional Anesthesia and Pain Medicine in New Orleans and has now been published in the society’s official journal, Regional Anesthesia and Pain Medicine.

Study participants had experienced post-amputation pain for up to 30 years. All participants underwent ultrasound-guided placement of SPR’s MicroLeads™ which are constructed using a tiny 100-micron wire, about the size of a human hair. Participants were then randomized to receive treatment using SPRINT PNS for 8 weeks, or placebo for four weeks and SPRINT PNS for 4 weeks.

Dr. Christopher Gilmore of the Center for Clinical Research in Winston-Salem, NC and principal author, stated: “The results are quite provocative and lead one to question whether a permanently implanted neurostimulation device is necessary for many patients who respond to a temporarily implanted lead. It is also encouraging to see that results are similar to those we’ve seen in patients with low back pain and shoulder pain.”

“This latest study builds on the growing body of evidence demonstrating that our SPRINT PNS System is able to deliver sustained and significant pain relief after the completion of its 60-day treatment,” said Maria Bennett, CEO of SPR Therapeutics, Inc. “We are also encouraged by SPRINT’s early commercial success and look forward to working with our many physician partners to expand the availability of this treatment to patients who could benefit from a non-opioid and non-surgical solution for their pain.”

About SPRINT® PNS System

The SPRINT Peripheral Nerve Stimulation (PNS) System is the only percutaneous PNS device that is FDA-cleared for both chronic and acute pain, including post-operative and post-traumatic pain. The SPRINT PNS System leads are placed by a physician during an outpatient procedure without surgery, incisions, tissue destruction or anesthesia, and are connected to a wearable stimulator that delivers stimulation for up to 60 days of therapy, after which the leads are withdrawn. In multiple studies, the SPRINT system has demonstrated significant and sustained pain relief following the 60-day treatment. Physicians have used the SPRINT system to treat post-amputation pain, inoperable joint pain, lower back pain, complex regional pain syndrome (CRPS), and post-operative pain following joint replacement and surgical reconstruction (partial listing).
