Clinical Trial: Radioimmunoimaging of Light Chain (AL) Amyloidosis
Study Status: Completed
Recruit Status: Completed
Study Type: Interventional
Official Title: Radioimmunoimaging (PET/CT) of Patients With AL Amyloidosis Using the 124I-Labeled Amyloid-Reactive Monoclonal Antibody (mAb) Murine (Mu) 11-F4
Brief Summary: The purpose of the study is to determine the capability of a radiolabeled amyloid-reactive monoclonal antibody (mAb) to document the presence and distribution of amyloid deposits by PET/CT imaging in patients with AL amyloidosis.
Detailed Summary: To be eligible for this study, patients must have a confirmed diagnosis of AL amyloidosis without significant cardiac (New York Heart Association class IV) disease and not be on kidney dialysis. Additionally, after testing, their blood must not contain antibodies to mouse proteins. The study requires an intravenous infusion, given over 10 minutes, of the radiolabeled antibody, followed 48 hours later by a PET/CT scan. A repeat scan is done 5 days after infusion of the antibody. A 5-ml blood specimen needs to be furnished 4 and 8 weeks after the antibody infusion.
