Eligible subjects will receive a single dose of radiolabeled AT-03, a fusion protein of serum amyloid P and a single chain Fc receptor. Repeat Positron Emission Tomography/Computed Tomography (PET/CT) scans will be performed over a ~7 day period to assess the biodistribution of AT-03 to amyloid-containing tissues in patients with systemic amyloidosis.
This is a single center Phase 1 study is to evaluate the biodistribution of radiolabeled AT-03 in patients with systemic amyloidosis.
