New Data Demonstrate Greater Pain Relief With Boston Scientific Precision Spectra™ Spinal Cord Stimulator System
MARLBOURGH, Mass., June 10, 2015 /PRNewswire/ — Boston Scientific Corporation (NYSE: BSX) presented new data demonstrating that the Precision Spectra™ Spinal Cord Stimulator (SCS) System provided 1.5 times better overall pain relief and 2 times better low back pain relief than the previous generation Precision Plus™ SCS system. The improved outcomes with the Precision Spectra System were achieved in conjunction with the use of the proprietary Illumina™ 3D neural targeting software, designed to target pain with point-and-click simplicity. Results from the LUMINA cohort of the Precision Spectra System observational study were presented this week at the International Neuromodulation Society 12th World Congress in Montreal, Canada.
The LUMINA cohort includes three patient groups: 213 consecutive patients treated with the Precision Spectra System for up to 24 months post-implant; 130 consecutive patients treated with the previous generation system, Precision Plus™, in a comparative evaluation with the Precision Spectra System; and 25 consecutive patients treated with the Precision Spectra System and the new CoverEdge 32 Surgical Leads for up to 6 months post-implant.
“The results are exciting because we looked at consecutive patients – some with only low back pain – in a real-world setting,” said Julie Pilitsis, M.D., Ph.D., associate professor, Albany Medical College and one of the lead investigators for this study. “This is strong clinical evidence of the effectiveness of the Precision Spectra System in treating the types of challenging chronic pain patients that physicians see every day.”
Key findings of the study included:
LUMINA Spectra group:
- Sustained and highly significant reduction in overall pain from an average baseline score of 7.17 to 2.98 at 24 months post-implant (N= 117), as measured on the 0-10 numeric rating scale (NRS)
- In a subset of patients with only low back pain (N=51), a sustained and highly significant reduction from an average baseline score of 7.21 to 3.20 at 24 months post-implant
- Significant reduction in disability (N=51), maintained out to 12 months, as measured by the Oswestry Disability Index.
- Comparison between the Precision Spectra and Precision Plus Systems groups:
- Responder rates (greater than or equal to 50% pain reduction) at 12 months post-implant for the Precision Spectra System were 72% for overall pain, 82% in leg pain only patients and 71% in low back pain only patients. For low back pain, the improvement with Spectra was more than twice that of the previous generation system group (Precision Plus™).
LUMINA Surgical group:
- Highly significant reduction in overall pain from an average baseline score of 7.7 to 2.7 at 6 months post-implant (N=23).
- In a subset of patients with only low back pain (N=9), 90% responder rate and a highly significant reduction from an average baseline score of 7.8 to 1.6 at 6 months post-implant.
“We designed the Precision Spectra SCS System to achieve even better outcomes when treating low back pain,” said Maulik Nanavaty, president, Neuromodulation, Boston Scientific. “These real-world clinical data demonstrate that the Precision Spectra System with our proprietary neural targeting software is a significant scientific advancement in pain management.”
The LUMINA cohort is part of the Boston Scientific PRO observational study.
About Chronic Pain
More than 100 million Americans suffer from chronic pain. Living in constant pain for an extended period of time can have a devastating impact on quality of life for many patients; without relief, or the hope for relief, many patients lose the ability to sleep, work and function normally. In particular, conventional spinal cord stimulator therapy can be effective in treating low back pain but not all patients get optimal relief. As a result, there is a continuing need for new therapies and technologies to meet this very specific pain area.
About the Precision Spectra SCS System
The Precision Spectra SCS System is the first and only SCS system with Illumina 3D™ software and 32 contacts, and is designed to provide improved pain relief to a wide range of patients who suffer from chronic pain. Prior to the release of the Precision Spectra SCS System with 32 contacts, SCS systems offered a maximum of 16 contacts and two lead ports, with each lead port allowing the placement of a single lead. Additional lead ports give physicians more flexibility to cover their patients’ pain at the time of implant and more flexibility to adapt to changing pain patterns in the future. With more contacts, the Precision Spectra SCS System also offers more coverage of the spinal cord for the management of chronic pain. Popular Mechanics magazine awarded the Precision Spectra System the 2014 “Breakthrough Award” in the field of medical devices for its innovation in meeting the needs of patients with chronic pain.
