Trial summary

Pain affects up to 30% of the general population. In particular, neuropathic pain (NeP) is caused by lesion or desease affecting peripheral or central somatosensory pathways and affects 7% of the adult population. Read more about this study

About this study

Pain affects up to 30% of the general population. In particular, neuropathic pain (NeP) is caused by lesion or desease affecting peripheral or central somatosensory pathways and affects 7% of the adult population. Despite the availability of evidence based pharmacological and surgical treatment for NeP, about 50% of patients remais symptomatic despite best medical treatment. Some neuropathic pain syndromes are specially refractory. In particular, central NeP is caused by disease or lesion to central structures involves in somatosensory integration of nociceptive information is non-responsive to drugs usually employed in other NeP syndromes. Classical neuromodulatory techniques such as conventional repetitive Transcranial Magnetic Stimulation aiming at the motor of prefrontal cortices are ineffective to relieve pain in this population. Recently new technology advances have made possible non-invasive stimulation of deeper cortical targets. Some of them are activelly involved in the integration of the perception of pain, such as the anterior cingulate cortex or the posterior insula. The aim this study is to treat 90 patients with central pain (post stroke pain, spinal cord lesions after trauma or demyelinizating diseases) under best medical pharmacological treatment in three different conditions: AAC (n= 30 with the H-Coil), Superior Posterior Insula (SPI) n=30 cooled double cone coil double cool coil, and sham(n=30). Each patients will undergo daily stimulation for a week, then weekly stimulations for 3 months (total of 17 sessions). The main study outcome is pain relief at the last stimulation week (visual-analogic scale). Secondary end-points are changes in the McGill Pain Questionnaire, Neuropathic Pain Symptom Inventory, DN4 questionnaire, SF -36, brief pain inventory and cognitive assessment including the trail making test A and B, Strrop color interference test, and subscalles from the CERAD. All patients will undergo quantitative sensory test and measurements of cortical excitability over M1 before and after to treatment.

Questions about this trial

What is this clinical trial studying?

A study testing deep rTMS in people with Pain and Spinal Cord Injury, run by University of Sao Paulo at 1 site in Brazil.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 10 May 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Brazil. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in baseline of Pain (time frame: base line (moment of inclusion) and end of each session rTMS (4X in three months)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01932905, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 May 2017.
