About this study

The purpose of this study is to see if the spine shows areas of inflammation using a specific type of imaging (pictures).

Read the detailed description

The purpose of this study is to determine if inflammation around the spinal nerves can be identified using a radioactive tracer [11C] PBR28 and integrated PET/MRI scan for the purpose of better treating patients who have radicular lumbar pain with epidural steroid injections.

Conditions
Sciatica
Being tested
Radioactive dye, PET/MRI, Blood draw

What participants receive

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

  • Radioactive dyeDrug

    Also called [11C]PBR28

    The radioactive dye [11C]PBR28 will be administered through an intravenous line (IV).

  • PET/MRIRadiation

    Also called Integrated MR-PET 3 Tesla scanner (Siemens Biograph mMR).

    All subjects will undergo a simultaneous PET/MRI scan. The scan will be up to 2 hours long.

  • Blood drawOther

    Up to 11 tablespoons of blood will be drawn through an intravenous line (IV-line) for two purposes: 1) testing for the subject's genetic affinity to the radioactive dye, and 2) testing for the presence inflammatory biomarkers.

What is being measured

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

  1. Inflammation in the spine

    The presence of inflammation in the spine using the radioactive tracer [11C]PBR28.

    Measured: 2 hours

Secondary outcomes (1)
  1. Pain Scores on the Visual Analog Scale (VAS)

    The subject's pain score (VAS) at baseline and up to 3 months after the ESI treatment.

    Measured: up to 3 months

Questions about this trial

What is this clinical trial studying?

An observational study of Sciatica, run by Massachusetts General Hospital 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 8 inclusion and 17 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: finished, as of the sponsor's last update on 16 Sep 2019. 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?

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?

Inflammation in the spine (time frame: 2 hours). 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 16 Sep 2019.
