Официальное название
PET/CT Imaging Of Subjects With Lumbar Spinal Stenosis Or Carpal Tunnel Syndrome Using Amyloid-Reactive Peptide 124I-Evuzamitide
Обзор
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.
Подробное описание
This is a single center, open label, pilot study using an amyloid-reactive peptide labeled with iodine-124 (124I-evuzamitide) and PET/CT imaging to detect the presence of cardiac and extracardiac amyloid in patients who have undergone surgical intervention for lumbar spinal stenosis (LSS) or carpal tunnel syndrome (CTS) and who have amyloid-positive connective tissue \[ligamentum flavum (LF) in LSS patients or tenosynovium in CTS patients\] assessed at the time of the corrective surgery.
Вмешательства
- Препарат 124I-evuzamitide
124I-evuzamitide is an iodine-124 (124I) labeled 45 L-amino acid peptide (also known as p5+14) suitable for single dose PET/CT imaging. The peptide binds many forms of amyloid through multivalent electrostatic interactions with the amyloid fibril and with the ubiquitous amyloid-associated hypersulfated heparan sulfate proteoglycans.

Критерии участия
Критерии включения
- Must be ≥ 60 years of age.
- Must have given written informed consent (signed and dated) and any authorizations required by local law and be able to comply with all study requirements.
- Must have a Congo red positive ligamentum flavum or tenosynovial specimen analysis after laminectomy or carpal tunnel release surgery that is visually categorized as either "extensive" amyloid load or "mild/moderate" amyloid load by an experienced reviewer.
- Those with mild/moderate amyloid load in the connective tissue who also have a history of at least one other orthopedic clinical manifestation, including, but not limited to, carpal tunnel syndrome, lumbar spinal stenosis, trigger finger, biceps tendon rupture, and shoulder/hip/knee arthroplasty.
- Females must be non-pregnant and non-lactating.
Критерии исключения
- Subjects on dialysis.
- Subjects with a confirmed diagnosis of systemic amyloidosis, other than musculoskeletal tissue.
- Inability or unwillingness to comply with the study requirements.
- Subjects taking heparin, or heparin derivatives (e.g. low molecular weight heparins) for anticoagulation.
- Inability to lie still for \~40 minutes on the PET/CT scanner.
- History of iodine (potassium iodide) allergy.
- Other reason that would make the subject inappropriate for entry into this study.
