NCT04015791

Brief Summary

A prospective, double blinded, multi-center study to assess the validity and clinical utility of the pre-operative NOCISCAN-LS software in the identification of painful lumbar discs, and the correlation with improved surgical outcomes at 3, 6, 12 and 24 months (follow-up) following spine surgery in a single enrollment arm of subjects with chronic symptomatic single level degenerative disc disease (DDD) at L3 to S1, but with two evaluation groups- Match Group and Miss Group,of subjects based on the association between the NOCISCORE results of treated and untreated disc levels.

Outcome Measures

Primary Outcomes (1)

  • Oswestry Disability Index Assessment to assess improvement in lumbar pain

    Oswestry Disability Index is an index derived from Oswestry Low Back Pain Questionnaire used in several studies to quantify disability for low back pain. Each of the 10 items is scored from 0-5. The maximum score is therefore 50. This will be completed at 12 month follow up to see if there is an improvement of at least 15 points at 12 months Follow-up for Match Group versus Miss Group subjects. Mean Oswestry Disability Index score changes at 3, 6 and 24 months post-operative follow-up will be evaluated for Match versus Miss Group

    24 months

Secondary Outcomes (2)

  • Visual Analog Scale (VAS) to assess the intensity of pain

    2 years

  • Demonstrate correlation of NOSCISCORE results to Provocative Discography +/- results in subset of study subjects that receive pre-operative provocative discogram

    24 months

Study Arms (2)

Match Group

Surgery conducted at the disc level corresponding with the highest level of NOCISCORE value in the subject and that is classified as either NOCI + or NOCI mild

Other: NOCISCAN-LS Disc MR Spectroscopy

Miss Group

Surgery conducted at a disc that: (a) corresponds with a low relative NOCISCORE value in the subject and that is classifies as NOCI - or (b) excludes the disc level with the highest NOCISCORE value in the subject and that is classifies as NOCI+ or NOCI mild

Other: NOCISCAN-LS Disc MR Spectroscopy

Interventions

The investigational Nociscan Suite is a software suite that works with existing high field MR systems and MRS pulse sequence via and optimized protocol to conduct MRS exam of lumbar discs. The software suite post-processes the NOCISCAN-LS disc MRS exam data to calculate ratios of spectroscopic signals at regions along the MRS frequency spectrum associated with certain chemicals that change with degeneration and pain

Sampling MethodProbability Sample
Study Population

Up to 240 subjects that are approved and scheduled for surgery at a single level from L3 to S1 to treat chronic, severe, primary axial, discogenic, low back pain via maximum of 14 sites

You may qualify if:

  • Has history consistent with degenerative disc disease as noted by back pain of discogenic origin with or without leg pain
  • Has one of more of the following conditions as documented by CT or MRI and plain X-rays:
  • Modic changes
  • High intensity zones in the annulus
  • Loss of discogenic height
  • Decreased hydration of the disc
  • Has single level symptomatic degenerative involvement from L3 to S1 in which surgical treatment is indicated
  • Skeletally mature male or female (non-pregnant) between 18 and 70 years of age
  • Pre-operative score ≥ 40% on Oswestry Disability Index
  • VAS back pain score ≥ 40 mm and that is greater than the VAS leg pain scores
  • Patient has failed at least ≥6 months of non-operative treatment that may have included physical therapy, bed rest, anti-inflammatory or analgesic medications, chiropractic care, acupuncture, massage therapy or home-directed lumbar exercise programs
  • In subject who receives pre-operative provocative discography (PD), the PD was performed more than 6 week prior to the scheduled NOCISCAN- LS Exam OR Is scheduled to be conducted after the Nociscan exam
  • Subject is willing to sign an Institutional Review Board approved Informed Consent and HIPAA Authorization forms, and is physically and mentally able to complete study forms and otherwise willingly adhere to the requirements of the protocol in the opinion of the investigator

You may not qualify if:

  • Has primary diagnosis of spinal condition other than degenerative disc disease at the involved level;
  • Has had prior lumbar back surgery or intradiscal treatments at any lumbar level (Note: diagnostic provocative or anesthetic discography are not excluded; micro-discectomy +- laminectomy patients greater than 6 months postop are not excluded)
  • Surgery planned at more than one level
  • Radiographic evidence of clinically relevant lumbar vertebral abnormalities, including
  • Greater than Grade 1 spondylolisthesis according to Meyerding classification at the involved level;
  • Any posterior lumbar element insufficiency (e.g. Spondylolysis, pars fracture, or prior facet resection;
  • Lumbar scoliosis with a Cobb angle of greater than 11 degree
  • Symptomatic kyphosis or flat black syndrome
  • Evidence of prior fracture or trauma to the L1, L2,L3, L4 or L5 levels in either compression or burst; Note: Modic end plate changes will not be excluded
  • Radiographic evidence of lumbar disc herniation with extrusion
  • Clinically significant spinal canal stenosis as assessed by the Investigator
  • Any significant motor strength deficit in lower extremities
  • Suspicion of Sacro Iliac and/ or Facet joint pain as the primary pain generator;
  • Has a condition that requires post-operative medications that interfere with fusion, such as immunosuppressive drugs, steroids or prolonged use of non-steroidal anti-inflammatory drugs. This does not include low dose aspirin for prophylactic anticoagulation
  • Has active bacterial infection, either local or systemic and/or potential for bacteremia
  • +4 more criteria
