  Purpose

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.

Intervention Model: Single Group Assignment
Masking: Open Label

Primary Outcome Measures:
  • 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. [ Time Frame: Five days post PET/CT scan ] [ Designated as safety issue: Yes ]
    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.

Primary Completion Date: July 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 124I-labeled anti-amyloid mAb 11-1F4
124I-labeled anti-amyloid mAb 11-1F4 will be infused on day 0. Two and 5 days later, PET/CT scans will be performed.
Biological: Single infusion of 124I-labeled anti-amyloid mAb 11-1F4: 2 mCi (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, 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.

  Eligibility

Criteria

Inclusion Criteria:

  • Patients with a confirmed diagnosis of AL amyloidosis.

Exclusion Criteria:

  • New York Heart Association class IV
  • On renal dialysis
