What You Need to Know Before You Apply

What is the purpose of this trial?

This clinical trial will use the amyloid-binding radiotracer, 124I-evuzamitide, to potentially detect amyloid, in the heart and elsewhere, in patients who have a history of lumbar spinal stenosis and/or carpal tunnel syndrome.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking heparin or heparin derivatives (blood thinners).

How does the drug 124I-evuzamitide differ from other treatments for spinal stenosis?

The drug 124I-evuzamitide is unique because it involves a radiolabeled component (124I), which may allow for targeted delivery or imaging capabilities, unlike traditional treatments for spinal stenosis that do not typically use radiolabeled compounds. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• 124I-evuzamitide

Trial Overview The intervention being studied is an amyloid-binding radiotracer called 124I-evuzamitide, used during PET/CT scans to visualize amyloid presence associated with various syndromes including cardiac conditions.

How Is the Trial Designed?

Group I: Biodistribution Experimental Treatment 1 Intervention

Participants will be administered \~1 mCi of 124I-evuzamitide (up to 1 mg of peptide) by IV push at a proposed rate of \~1 mL per 5 seconds. Three hours after injection, a PET/CT image acquisition from shoulder to thigh as well as a 10 min static PET image of the heart will be performed.
