Summary

This study will investigate 99mTc-p5+14, an amyloid-reactive synthetic peptide, p5+14, radiolabeled with technetium-99m, as a radiotracer for detecting paamyloid deposits in patients with AL or ATTR-associated systemic amyloidosis, notably with cardiac involvement.

Conditions

  • Systemic Amyloidosis

Interventions

DRUG

99mTc-p5+14 is an amyloid reactive peptide labeled with technetium-99m.

Peptide p5+14 is a pan-amyloid reactive, synthetic 45 L-amino acid polypeptide with a net +12 positive charge that can bind two major components of all extracellular amyloid deposits: (i) hypersulfated heparan sulfate glycosaminoglycans (proteoglycans) and (ii) amyloid fibrils. The polypeptide, labeled with iodine-124, has been shown (study AMY1001) to bind amyloid in all organs including the heart. This study will evaluate a Tc-99m-labeled version of the peptide for gamma imaging.

DRUG

99mTc-Pyrophosphate and 99mtc-p5+14 - an Amyloid Reactive Peptide Labeled With Technetium-99m.

99mTc-PYP is an FDA-approved, commercially available bone-seeking radiotracer used routinely in nuclear medicine. 99mTC-PYP imaging is used clinically for the diagnosis of cardiac ATTR amyloidosis.
