Primary Outcome Measures:
  • Assessment of myocardial sympathetic innervation (as either normal or abnormal) for identifying risk of adverse cardiac event. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Assessment of myocardial sympathetic innervation (numerical H/M ratio) for identifying risk of adverse cardiac event. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Quantitative myocardial 123I-mIBG uptake to identify HF subjects at higher risk of earlier HF progression, potentially fatal ventricular arrhythmias, or cardiac death. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Modeling to predict risk for adverse cardiac events. [ Time Frame: 24 months or confirmation of 56 adverse cardiac events ] [ Designated as safety issue: No ]
  • Safety profile [ Time Frame: 24 hours post dose ] [ Designated as safety issue: Yes ]

Detailed Description:

This is a phase 3, open-label, multicenter trial to investigate the prognostic usefulness of 123I-mIBG imaging to identify those subjects with New York Heart Association (NYHA) Class II and III HF who will experience an adverse cardiac event. The study will consist of a maximum of 587 subjects (525 HF subjects and 62 control subjects) administered 123I-mIBG at approximately 40 centres in the United States. Subject status will be monitored at 6-week intervals post-administration of 123I-mIBG to assess the occurrence of adverse cardiac events. The median follow-up is expected to be 9 months.


Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Study subjects must be adults with an established diagnosis of heart failure (New York Heart Association Class II or III) and reduced left ventricular ejection fraction (LVEF) (< 35%) or be healthy volunteers without heart disease.

Exclusion Criteria:

  • Healthy volunteers are not eligible if they have a history diabetes mellitus, signs/symptoms of neurological disease (eg, Parkinson's Disease, multiple system atrophy, Parkinsonian syndromes), or other diseases known to affect the sympathetic nervous system.
  • Subjects with New York Heart Association Class I or IV heart failure are not eligible.
