About this study

Official title: DOLORisk: Understanding Risk Factors and Determinants for Neuropathic Pain - Peripheral Physiological Measures as Determinants of Pain Risk

This study evaluates peripheral nervous system function using Multiple Excitability Measures (MEM) to obtain "electrophysiological pain phenotypes"

Read the detailed description

Using MEM for peripheral sensory and motor axons we want to identify a set of excitability measures that:

  1. Correlate with parameters of clinical pain and of pain processing in existing pain patients (cross sectional study), with the aim to obtain an objective Pain Biomarker.
  2. Predict development of neuropathic pain in susceptible patients (longitudinal study). Neuropathic Pain Predictor for patients:
  3. Undergoing surgical procedures associated with a relatively high risk of developing neuropathic pain such as thoracotomy and hernia repair ii. Planning to start chemotherapy with potentially neurotoxic agents such as vincristine

    The technique of threshold tracking can be used to obtain several measures of peripheral nerve excitability (Multiple Excitability Measures or MEM), such as refractoriness, supernormality, strength-duration time constant and 'threshold electrotonus' (i.e. the changes in threshold produced by long-lasting depolarizing or hyperpolarizing current pulses). Each of these measurements depends on membrane potential and on other biophysical properties of the axons. Many of these excitability parameters are very constant among different subjects, while other, such as the current/threshold parameters and the super/sub-excitability parameters, appear to be characteristic of an individual

What is being measured

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

  1. Electrophysiological pain phenotypes using MEM. Pain biomarker

    Correlate with parameters of clinical pain and of pain processing in existing pain patients

    Measured: Single assessment (cross sectional study) at the first and only visit

  2. Electrophysiological pain phenotypes using MEM. Pain predictor

    Predict development of neuropathic pain in susceptible patients

    Measured: Single assessment at baseline, before any procedure (surgery/chemotherapy)

Questions about this trial

What is this clinical trial studying?

An observational study of Polyneuropathies and Peripheral Nerve Injuries, run by Neuroscience Technologies SLP, Barcelona at 1 site in Spain.

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 1 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 23 Aug 2018. 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 Spain. 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 Romà Solà, MD (0034 934020164, rsola@nsc-tec.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Electrophysiological pain phenotypes using MEM. Pain biomarker (time frame: Single assessment (cross sectional study) at the first and only visit). The study lists 2 primary outcomes in all. 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 23 Aug 2018.
