Meta-Iodobenzylguanidine Scintigraphy Imaging in Patients With Heart Failure and Control Subjects Without Cardiovascular Disease

This study has been completed.
Sponsor:
Information provided by (Responsible Party):
GE Healthcare
ClinicalTrials.gov Identifier:
NCT00126425
First received: August 2, 2005
Last updated: October 19, 2016
Last verified: October 2016
  Purpose
The study is designed to study the utility of 123I-mIBG as a diagnostic imaging agent to predict cardiac outcomes in subjects with heart failure and in comparison to subjects without cardiovascular disease.

Condition Intervention Phase
Heart Failure, Congestive Drug: 123I-mIBG (meta-iodobenzylguanidine) Phase 3

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Diagnostic
Official Title: An Open-Label, Multicenter, Phase 3 Study Evaluating the Prognostic Usefulness of I-123 mIBG Scintigraphy for Identifying Subjects With Heart Failure Who Will Experience an Adverse Cardiac Event

Primary Outcome Measures:
  • Relationship Between the Occurrence of Adverse Cardiac Event and 123I-mIBG Uptake on Planar Scintigraphy Categorized as High or Low Heart to Mediastinum (H/M) Ratio [ Time Frame: Approximately 24 months from the date of administration of 123I-mIBG ]
    H/M ratio for 123I-mIBG uptake at 3 hours 50 minutes post administration was calculated by dividing the counts/pixel in the total myocardium region of interest (ROI) by the counts/pixel in the 7x7 pixel mediastinal ROI. Assessments were done by 3 independent readers. H/M ratios were categorized as 'Low' and 'High' based on being <1.6 or ≥1.6 respectively. The efficacy of 123I-mIBG was based on the prognostic value of the imaging data collected relative to time to adverse cardiac events.
