124I-p5+14 Injection Safety in Subjects With Systemic Amyloidosis

This is a single-center, exploratory, Phase 1 Positron Emission Tomography/x-ray Computed Tomography (PET/CT) imaging study to detect amyloidosis that will enroll patients with a confirmed diagnosis of systemic amyloidosis. The purpose of this exploratory trial is to assess the safety and efficacy of 124I-p5+14 Injection at a single-injection dose adequate for imaging amyloid deposits by using PET/CT imaging in subjects with confirmed systemic Immunoglobulin Light Chain-associated Amyloidosis (AL), Transthyretin-associated Amyloidosis (ATTR), Leukocyte Chemotactic Factor 2-associated Amyloidosis (ALect2) as well as other types.
