Trial summary

The main goal of this study is to determine if static or dynamic [18F]NaF PET/CT (positron emitting tomography) can identify the source of lower backpain in at least 20% of the patients experiencing lower backpain, yet could not be diagnosed from MRI or CT scans. Read more about this study

About this study

The main goal of this study is to determine if static or dynamic [18F]NaF PET/CT (positron emitting tomography) can identify the source of lower backpain in at least 20% of the patients experiencing lower backpain, yet could not be diagnosed from MRI or CT scans.

Read the detailed description

Patients with chronic lower backpain are routinely scanned with MR and/or CT to diagnos the source of pain. Larger studies have reported that approximately 20% of patients are given a certain diagnosis from the scans and in the majority of cases the source of the pain is not determined. The use of [18F]NaF PET/CT to map bone perfusion and metabolism is a routine clinical scan that can potentially identify the source of lower backpain in MRI and CT negative patients.

Hypothesis: That [18F]NaF PET/CT bone metabolism and bone perfusion images would contain information that allow the correct diagnosis in at least 20% of patients where MRI and CT images did not reveal pathology.

Questions about this trial

What is this clinical trial studying?

An observational study of Lower Back Pain Chronic, run by Copenhagen University Hospital, Rigshospitalet at 1 site in Denmark.

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 3 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: under way, not looking for participants, as of the sponsor's last update on 6 Apr 2023. 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 Denmark. 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?

This study is still under way. Results are not available in the source record yet.

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?

Abnormal foci of elevated bone metabolism, blood pooling or bone perfusion (time frame: 1 hour examination). 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 NCT05801848, which also lists 2 linked publications.

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 6 Apr 2023.
