Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 22 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Patients who have intractable pain, as defined by: chronic (>1 year), severe (VAS score > 6/10), and persistent (not responsive to medication or relevant surgical options) without cognitive impairment or comorbidities affecting surgical risk.
  • Patients that have been medically cleared for DBS surgery by the consensus committee.
  • Not exhibiting significant distress, anxiety, or psychological disturbance that may be worsened due to externalized leads or potential complications or by study recording or tasks.
  • Motorically and cognitively capable of completing evaluations and consent.
  • Motorically and cognitively capable of participating in the study's computer-based tasks.
  • Informed consent signed by the subject.
  • Patient age between 22 to 75 years old.

Who cannot join

  • Patients that are not a candidate for DBS. This may occur for example, if they are unable to properly operate the neurostimulator. Also, several medical procedures and studies are not compatible with DBS. These include diathermy, transcranial magnetic stimulation, MRI procedures using radio-frequency coils, electroconvulsive therapy. Patients are receiving these treatments or plan to receive them in the future will not be eligible. Also, the safety of DBS has not been established for patients with a previous surgical ablation, dementia, coagulopathies, moderate to severe depression, or patients who are pregnant. Patients with these conditions will also not be eligible. Finally, DBS may be affected by or may affect other medical devices including cardiac pacemakers/defibrillator, ultrasonic equipment, radiation therapy, and incomplete (abandoned) prior DBS systems. Patients with these conditions/devices will not be eligible for the study.
  • Subjects who have pain that is not severe enough to be considered for DBS: shorter than 1 year duration, VAS score < 6/10), responsive to medication or relevant surgical options.
  • Subjects deemed to have a psychiatric illness that would potentially interfere or cause undue stress during the awake implantation surgery, the 1-3 week stimulation trial period, or the long term care of the DBS system are ineligible to undergo the DBS implantation procedure and thus would not be able to participate in this trial.

About this study

Over the last 30 years, deep brain stimulation (DBS) has allowed tens of thousands of patients to receive relief of neurological symptoms that were refractory to standard medical treatment. Furthermore, by providing a rare window into the electrophysiological activity of the awake, human brain, DBS has facilitated invaluable advances in scientific understanding. These advances have then, in turn, allowed for further therapies to be developed for an ever growing population of patients that benefit from DBS therapy. This study hopes to add to this growing body of knowledge by implanting leads within, and recording from, the sensory thalamus and periaqueductal gray (PAG) in patients with chronic pain. Specifically, we hope to establish the long-term safety of DBS leads within the periaqueductal gray and sensory thalamus for the treatment of chronic pain. Furthermore, by recording from the electrodes of DBS patients implanted for treatment of their chronic pain, we hope to understand how the pain network responds to sensory stimuli and how DBS changes this response.

Questions about this trial

What is this clinical trial studying?

A study testing DBS for Chronic Pain in people with Chronic Pain, run by St. Joseph's Hospital and Medical Center, Phoenix at 1 site in United States.

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 7 inclusion and 3 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: enrolling by invitation, as of the sponsor's last update on 9 Dec 2024. 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 United States. 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. 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?

This study is still under way. Results are not available in the source record yet.

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?

Safety of DBS for Chronic Pain as Assessed by Incidence of Treatment-Related Adverse Events (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Dec 2024.
