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 18 to 99 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Cases will be collected at each participating centre. Every effort will be made to accumulate a well phenotyped cohort of patients with persistent CLBP, sub-grouped into 6 categories: discogenic pain, spinal stenosis (congenital or acquired), facet joint pain, sacroiliac joint pain, low back pain with radicular pain (not predominant radicular pain) and widespread low back pain. Controls (patients without chronic/persistent pain as defined above) will be retrieved from 2 different sources: Existing biobanks of healthy subjects which have collected information about chronic/persistent back pain. Subjects from the companion prospective study on acute LBP who will not have developed CLBP. Age (decades) and gender distribution of controls will be similar to cases.

Who may be able to join

  • age: older than 18;
  • chronic/persistent pain (pain lasting longer than 12 weeks) between the costal margins and gluteal fold, with or without symptoms into one or both legs
  • written informed consent signed;
  • Caucasian ancestry
  • age: older than 18;
  • without any chronic/persistent pain (pain lasting longer than 12 weeks) in the last one year;
  • written informed consent signed;
  • Caucasian ancestry

Who cannot join

  • evidence of clinically unstable disease;
  • severe psychiatric disorder (excluding mild depression) or mental impairment;
  • recent history ( < 1 year) of spinal fracture;
  • pain in the back due to spinal tumor or infection;
  • pregnancy

About this study

Low back pain (LBP) is one of the most common medical problems encountered in daily life; it is related to disability and work absence and accounts for high economical costs in Western societies.

Low-back pain is a diverse group of mixed pain syndromes (neuropathic and nociceptive) with different molecular pathologies at different structural levels displaying similar clinical manifestations. Currently, there are limited biomarkers (mostly imaging) or clinical findings that can be used objectively to help the physician in precise anatomic diagnosis leading to the safest and most cost-effective treatment for the patient (reduction of direct and indirect costs and improvement of treatment efficacy).

The main aim of this trial is to identify all "omics biomarkers" associated with susceptibility to chronic/persistent LBP and its different pathophysiology.

Read the detailed description

Retrospective observational multinational clinical study, with a case control design.

Investigators will compare "omic biomarkers" between patients with and without persistent chronic low back pain (CLBP).

"OMIC" biomarkers investigated will be genetics, glycomics and activomic. Genetics through GWA studies has already obtained important results in pain research; however concerning low back pain, there is not yet suitable genotype-phenotype correlations helpful to stratify patients.

Glycomics is an emerging field that has recently been identified as a priority for the next decade by the US National Academies of Science. Many common complex diseases will be associated with specific changes in glycan structures. In addition, common genetic polymorphisms influencing glycosylation and consequent differences in glycome composition could be important diagnostic and prognostic markers. The first studies reporting protein glycosylation in large human population samples have been recently published by partners in the consortium. Reliable identification of valid associations between specific glyco-phenotypes and predisposition for the development or progression of a specific disease requires analysis of thousands of patients.

Activomics: combines data about enzymatic activity of numerous numerous post-translational modification proteins in an integrated model which provides dynamic characterization of the current state of an organism. In this project information about numerous proteases, kinases, phosphatases and glycosidases will be collected and used to complement the existing phenotype information.

What is being measured

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

  1. GENETIC OUTCOME

    The primary objective is to recognize genetic variants associated with persistent CLBP patients compared to patients without chronic/persistent pain. Through a Genetic Wide Association Study (GWAS) investigators will correlate genetic variants associated with persistent CLBP in a wide, international population of European ancestry.

    Measured: 30 months

Secondary outcomes (2)
  1. GLYCOMIC AND ACTIVOMIC OUTCOME

    Recognize Glycomic and Activomic data associated with persistent CLBP patients compared to patients without chronic/persistent pain. The sample size will better defined after the first interim analysis of first 400 patients.

    Measured: 30 months

  2. STRATIFICATION OF OUR POPULATION

    All "omic" data will be compared stratifying our population according to:

    • Pathophysiology: discogenic pain, spinal stenosis, facet joint pain, sacroiliac joint pain, low back pain with radicular pain (not predominant radicular pain) and widespread pain.
    • pain intensity
    • response to treatment
    • duration of pain

    Measured: 30 months

Questions about this trial

What is this clinical trial studying?

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 8 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?

Where is the study taking place?

The record lists 6 sites in Italy, United States, Australia, Belgium, Croatia. 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?

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?

GENETIC OUTCOME (time frame: 30 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 NCT02037789, 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 26 Sep 2016.
