About this study

Official title: Identifying Biomarkers and Changes in Cerebrospinal Fluid Collected Pre and Post Spinal Cord Stimulation: A Single Centre, Prospective, Exploratory Study in Subjects Suffering From Chronic Refractory Pain Conditions

This is a single center exploratory study in subjects suffering from chronic refractory pain to identify cellular, molecular and protein biomarkers within cerebrospinal fluid (CSF).

The study aims to identify any form of correlation between biological content of CSF and pain/treatment success. The study population include individuals suffering from chronic pain which has not been effectively treated with pharmacological treatment, medical intervention or alternative non-invasive treatments who have been scheduled for spinal cord stimulation.

Read the detailed description

This is a single centre exploratory study in individuals suffering from chronic refractory pain to identify cellular, molecular and protein biomarkers within cerebrospinal fluid (CSF).

The investigators aim to identify any form of correlation between biological content of CSF and pain/ spinal cord stimulator (SCS) therapy success. '

CSF will be sampled before and after SCS therapy, the samples will be analysed to explore and identify biomarkers that are potentially relevant to the chronic pain conditions

. All eligible participants who are enrolled in the study will undergo screening assessment. Specifically, assessments will include pain scores assessed by Visual Analogue Scale (VAS), quality of life as assessed by the EQ-5D, disability as assessed by the Oswestry Disability Index (ODI), quality of sleep as assessed by Pittsburgh Sleep Quality Index (PSQI), Pain sensation as assessed by Pain Map and neuropathic pain as assessed by Douleu Neuropathique 4 (DN4).

During trial implant participants will have CSF sample taken using lumbar puncture technique.

Following collection CSF sample will be analysed to Identify potential biomarkers.

All participants will return to the clinic 14 (± 7) days following the procedure to assess the outcome of their SCS trial and complete assessments which include Pain Map, Pain VAS, DN4 , PSQI , ODI , EQ-5D and Patients Global Impression of Change (PGIC).

Following this participants will be followed up for end of study visit. The second CSF sample will be taken at this visit using lumbar puncture technique. At this visit participants will further be asked to complete assessments including Pain Map, Pain VAS, DN4 , PSQI , ODI ,EQ-5D and PGIC.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Lumbar PunctureProcedure or surgery

    The participant is placed lateral or sitting position. Fluoroscopy may be used to guide sampling. Full aseptic technique is used throughout.

    The skin is prepared with either 2% chlorhexidine/70% alcohol or iodine. 1% lidocaine is used for skin local anesthesia an entry point is identified, this may be done using fluoroscopy. This will be at the lowest intervertebral foramina interspace to minimize the risk of spinal cord injury. A small amount to head up tilt will be allowed to optimize CSF flow.

    Sampling is done using a "needle through needle" technique. An epidural needle is used to identify the epidural space using loss of resistance to saline technique. A spinal needle (26G) is then passed through the epidural needle into the subarachnoid space. Correct entry is noted once CSF is noted in the needle hub and 5 ml taken. This sample is then sent off for analysis.

    Once the CSF is sampled, the needle is removed and pressure applied to the skin entry point.

What is being measured

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

  1. Pain VAS

    Visual Analogue Scale (VAS) used to assess improvements in pain. It is a continuous scale comprised of a horizontal line which is 10 centimeters (100mm) in length, anchored by 2 verbal descriptors, one which is no pain and the other worst imaginable pain. Lower scores denote a better outcome.

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

  2. Pain Map

    A pain checklist with a list of anatomical locations from which the participants selects relevant sites to the site of his/her pain. It is used to assess location of pain.

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

  3. Oswestry Disability Index (ODI)

    A self completed questionnaire used to assess changes in disability and health. The participants checks the statements which most closely resembles their situation. The scores for all the questions are summed with lower scores denote no disability.

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

  4. Patient Global Impression of Change (PGIC)

    Questionnaire used to assess patient satisfaction

    Participants will be asked to complete this questionnaires at follow up visits.

    .

    Measured: 6 Months

  5. Douleur Neuropathique 4 (DN4)

    A clinician-administered questionnaire consisting of 10 items. Seven items related to pain quality (i.e. sensory and pain descriptors) are based on an interview with the patient and 3 items based on the clinical examination. The questionnaire used to assess neuropathic pain

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

  6. EQ-5D-5L

    A self report questionnaire used to assess improvements in quality of life.

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

  7. Pittsburgh Sleep Quality Index (PSQI)

    A self report questionnaire that will used to assess improvements in sleep quality. The questionnaire consists of 19 items which measures several different aspects of sleep. Each item is weighted on a 0 - 3 interval scale, the overall score is calculated by totalling the seven component scores. Lower scores denote a healthier sleep quality

    Participants will be asked to complete this questionnaires at baseline and follow up visits.

    Measured: 6 Months

Questions about this trial

What is this clinical trial studying?

A study testing Lumbar Puncture in people with Neuropathic Pain, run by Guy's and St Thomas' NHS Foundation Trust at 1 site in United Kingdom.

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 6 inclusion and 2 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: stopped early, as of the sponsor's last update on 12 Jun 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 Kingdom. 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?

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?

Pain VAS (time frame: 6 Months). The study lists 7 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 12 Jun 2024.
