24-SMI-2014 is a Randomised Controlled Trial with an optional one way cross-over comparing Conservative Medical Management (CMM) to treatment with the Axium neurostimulator + CMM. Subject population is chronic inguinal pain refractory to previous surgical intervention (neurectomy).

Condition Intervention
Chronic Inguinal Pain Refractory to Previous Surgical Intervention (Neurectomy)
Device: Implantation with the commercially available Axium neurostimulator

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Crossover Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Randomised Controlled Trial to Evaluate the Efficacy of the Spinal Modulation Axium® NeuroStimulator THerapy as a Treatment for Persistent INGuinal Pain Following Surgical Intervention: SMASHING

Further study details as provided by St. Jude Medical:

Primary Outcome Measures:
  • Percentage of subjects experiencing ≥50% reduction in average daily pain intensity in the Axium Group as compared to the CMM only group using an eleven point (0-10) numerical pain rating scale (NPRS) [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Estimated Enrollment: 78
Study Start Date: December 2014
Estimated Study Completion Date: October 2017
Estimated Primary Completion Date: February 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Conservative Medical Management
Continued medical management restricted to exclude interventional pain treatments
Active Comparator: Axium Group
As the CMM group but also treated with Dorsal Root Ganglion stimulation using the Axium neurostimulator
Device: Implantation with the commercially available Axium neurostimulator


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Subject is at least 18 years old

  3. Chronic inguinal pain following Pfannenstiel Incision or Open Inguinal Hernia Repair for at least 6 months
  4. Previously undergone neurectomy procedure as a treatment for chronic inguinal pain
  5. Minimum daily average baseline pain rating of 5 out of 10 in the inguinal area on an 11-point NPRS
  6. Subject is able to provide written informed consent
  7. Meets of the inclusion criteria for the implantation of a neurostimulation system as set out by the Dutch Neuromodulation Society
  8. Subject has been screened by a multi-disciplinary panel including the designated psychologist of the Máxima Medical Center and deemed suitable for implantation

Exclusion Criteria:

  1. Female subject of childbearing potential is pregnant/nursing or plans to become pregnant during the course of the Trial
  2. Escalating or changing pain condition within the past month as evidenced by investigator examination
  3. Subject has had injection therapy or radiofrequency treatment of a target neural structure within the past 3 months

  5. Subject is unable to operate the device
  6. Subjects currently has an active infection
  7. Subject has participated in another clinical investigation within 30 days
  8. Subject has a coagulation disorder or uses anticoagulants that, in the opinion of the investigator, precludes participation
  9. Subject has a current or on going condition, which will probably require MRI investigation sometime in the following 2 years
  10. Subject has had a spinal surgical procedure at or between vertebral levels T10-L2
  11. Subject has been diagnosed with cancer in the past 2 years, except for skin malignancies.
