CONCEPT: Crossover Efficacy Pain Trial in Motor Cortex Stimulation for Intractable Neuropathic Pain

This study has been terminated.
(Based on a consistently low enrolment rate and procedural challenges that were unknown at study start. It was not based on safety or efficacy concerns.)

The CONCEPT study has been designed to evaluate the safety and the efficacy of Motor Cortex Stimulation (MCS) with a new cortical lead (circular lead, eight electrodes, Medtronic Inc, Minneapolis, USA) in the treatment of intractable neuropathic pain, in particular for central post-stroke pain (CPSP) and trigeminal neuropathic pain (TGN)/facial pain.

Condition Intervention Phase
Pain, Intractable Facial Pain Device: Cortical lead, 8 electrodes (Model 2976) with Synergy neurostimulator Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Prospective, Randomized, Double Blind, Crossover, Multi-center Study to Evaluate the Safety and the Efficacy of Motor Cortex Stimulation With the Cortical Stimulation Lead Model 2976 in Patients With Neuropathic Pain

Further study details as provided by Medtronic:

Primary Outcome Measures:
  • Adverse events reports
  • Pain assessed by Visual Analogue Scale (VAS)

Secondary Outcome Measures:
  • Quality of life
  • Disability
  • Analgesic, sedative or psychoactive medication intake

Estimated Enrollment: 104
Study Start Date: June 2005
Study Completion Date: March 2008
Primary Completion Date: March 2008 (Final data collection date for primary outcome measure)

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

Inclusion Criteria:

  • CPSP or TGN/facial pain refractory to other medical treatments
  • Pain > 1 year prior to baseline

Exclusion Criteria:

  • CPSP with important paresis/severe motor deficit in the area of pain
  • TGN/facial pain with complete deafferentation pain
  • Atypical facial pain, i.e. when objective evidence for neuropathic facial pain syndromes is lacking and when specific psychological and behavioral factors can be identified
  • Pain associated with malignant neoplastic disease anywhere in the body or head
  • History of epilepsy
  • Presence of a deterioration of cognitive functions
