Radioimmunoimaging of Light Chain (AL) Amyloidosis

Phase 1
Completed
Conditions
AL Amyloidosis
Registration Number
NCT01815086
Lead Sponsor
University of Tennessee
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 Description

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.

Primary Outcome Measures
NameTimeMethod
Determination of the capability of a radiolabeled amyloid-reactive monoclonal antibody (mAb) to document the presence and distribution of amyloid deposits by PET/CT in up to 30 patients with AL amyloidosis.Five days post PET/CT scan

PET/CT images will be taken 2 and 5 days post-radiolabeled antibody infusion to evaluate if there is organ/tissue uptake (greater than blood pool) and to determine if the presence of radiolabeled antibody correlates with clinically proven amyloid deposition.
