About this study

Official title: PREFerred Neurostimulation MODdalities to Treat Chronic Intractable Back Pain, A 3x3 Crossover Study

This is a prospective 3x3 crossover study with randomized treatment order, comparing the short-term efficacy of conventional-spinal cord stimulation (CON-SCS) with subcutaneous stimulatio, high frequency-spinal cord stimulation (HF-SCS), and Combination Therapy, in patients with chronic intractable back pain (with or without leg pain).

Read the detailed description

Patients will be preselected for inclusion in this study at the pain management center of Neurocenter of Southern Switzerland, Ente Ospedaliero Cantonale (EOC) Lugano, and will be informed about study-details by a study clinician. After informed consent signature, the participants with chronic intractable back or back and leg pain will be implanted with the stimulation lead(s). The leads are initially connected to an external trial neurostimulator. Patients will be implanted with two epidural leads and two subcutaneous leads. A three weeks trial phase will follow. The first two days after the leads implant will be without stimulation and thereafter alternating stimulation every week will start, randomly ordering the treatments using a Williams design balanced for first-order carryover effects (i.e. incorporating 6 different treatment orders), from:

  • 1) CON-SCS with Subcutaneous stimulation
  • 2) HF-SCS
  • 3) Combination Therapy A patient's favored SCS mode, providing that there is at least 50% reduction in pain intensity on the NRS in the trial phase, will then be implanted and patients will be followed up for 12 months.

Pain intensity and pain medication will be assessed with a pain diary at baseline and during the trial phase and will be furthermore measured after 3, 6, and 12 months after the implantation. Physical functioning, Pain Extent, Patient Global Impression of Change (PGIC), and Satisfaction with stimulation treatment (SST) will be assessed during the trial phase and will be furthermore measured after 3, 6, and 12 months after the Implantable Nerve Stimulator (INS) implantation. The other secondary outcomes will be measured at baseline, and after 3, 6 and 12 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. back pain intensity

    The difference in the intensity of back pain between the three neurostimulation modalities as measured by the numerical rating scale (NRS) from 0 to 10, where 0 is not pain and 10 is the maximum pain the person can experience, assessed at baseline and in the trial phase 21 days

    Measured: 21 days

Questions about this trial

What is this clinical trial studying?

A study testing Implantable Neurostimulator System (Spectra WaveWriter™ Spinal Cord Stimulator System), (Boston Scientific Neuromodulation Corporation, Valencia, California (CA), USA) in people with Chronic Low-back Pain, run by Ospedale Regionale di Lugano at 1 site in Switzerland.

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 4 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: status not confirmed, as of the sponsor's last update on 26 Mar 2021. 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 Switzerland. 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?

Results are not available in the source record.

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

Contact Eva Koetsier, MD PhD LLM (0041918119590, eva.koetsier@eoc.ch), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

back pain intensity (time frame: 21 days). 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 26 Mar 2021.
