Brief Summary:
The purpose of this investigational study is to study the effects of Stimgenics Spinal Cord Stimulation (SGX-SCS) in subjects with chronic, intractable pain of the trunk with lower limb pain, including unilateral or bilateral pain associated with the following conditions: failed back surgery syndrome, intractable low back pain and leg pain.

Condition or disease Intervention/treatment Phase
Chronic Low Back Pain Device: Stimgenics SCS Programming Approach Device: Standard SCS Programming Approach Not Applicable

Detailed Description:

This is an open-label prospective, randomized, controlled, multi-center study comparing Stimgenics Spinal Cord Stimulation (SGX-SCS) programming approach to Standard SCS programming approach.

Subjects meeting study entrance criteria will be randomized in a 1:1 ratio to one of two study treatment groups:

  • Test treatment group with SGX-SCS programming approach
  • Control treatment group with Standard SCS programming approach

Data at follow-up visits will be compared between the two treatment groups, and in reference to baseline assessments collected at the beginning of the study.

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The Percentage of Individual Responders [ Time Frame: 3 months ]
    Percentage of Participants with a 50% decrease in back pain at 3 months compared to baseline. Pain rating will be measured on the 10 cm Visual Analog Scale (VAS). Change in back pain score will be used to determine individual responder (e.g., 50% reduction in VAS compared to Baseline VAS).


Secondary Outcome Measures :
  1. Percentage of Individual Responders [ Time Frame: 3 months ]
    The percentage of Individual Responders (50% reduction in pain score rated on a Visual Analog Scale); Test for superiority

  2. Change in Back Pain Score [ Time Frame: 3 months ]
    Comparison of change from Baseline in back pain score (using Visual Analog Scale 0.0-10.0cm) determined at the 3- and 6-month visit after device activation, between test and control in a statistical test of non-inferiority. This is calculated as: Change from Baseline in Back Pain VAS = 3-Month Visit Pain VAS - Baseline Pain VAS.

  3. 6 Months Comparison of Back Pain Treatment Success [ Time Frame: 6 months ]
    Comparison of Back Pain Treatment Success (responder rate), measured as subjects with at least a 50% reduction in Back Pain Visual Analog Scale (VAS), evaluated at 6 months after device activation, between test and control

  4. Oswestry Disability Index (ODI) [ Time Frame: 3 months ]
    Oswestry Disability Index (ODI) evaluated at 3 months visit

  5. Adverse Events [ Time Frame: 3 months ]
    Frequency of treatment emergent adverse events
