Primary Outcome Measures:
  • Radioimmunoimaging of AL amyloid deposits [ Time Frame: 36 months ]

Secondary Outcome Measures:
  • Imaging of amyloid deposits as determined by PET/CT [ Time Frame: 10-14 days ]

Enrollment: 38
Study Start Date: November 2008
Study Completion Date: March 2012
Primary Completion Date: March 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
I-124 Mu 11-1F4 sterile injection
Single arm study
Biological: 124I-labeled monoclonal antibody Mu 11-1F4
Single infusion of radiolabeled antibody: 2mCi (1 mg)

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, over 10 minutes, of the radiolabeled antibody, followed 48 hours later by a PET/CT scan. A repeat scan is done 5 or 7 days after infusion of the antibody. A 5 ml blood specimen needs to be furnished 4 and 8 weeks after the antibody infusion.

Ages Eligible for Study:   21 Years to 90 Years   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Confirmed diagnosis of AL Amyloidosis

Exclusion Criteria:

  • New York Heart Association class IV
  • patient on renal dialysis
  • serum antibodies to mouse protein
