Further study details as provided by GE Healthcare:

Primary Outcome Measures:
  • - To demonstrate that 123I-mIBG planar scintigraphy is sensitive and specific in confirming or excluding the diagnoses of neuroblastoma and phaeochromocytoma.

Secondary Outcome Measures:
  • To determine the incremental value of single-photon emission computed tomography (SPECT) for improving the sensitivity and specificity of 123I-mIBG planar scintigraphy for the diagnoses of neuroblastoma and phaeochromocytoma.
  • To collect safety data on 123I-mIBG.

Estimated Enrollment: 185
Study Start Date: July 2005

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
  • Subject must either have:

    1. known or suspected neuroblastoma OR
    2. known or suspected phaeochromocytoma
  • Subjects are not eligible for the study if they have any clinically active, serious, life-threatening disease other than neuroblastoma or phaeochromocytoma with a life expectancy of less than 30 days or where participation in the study might compromise the management of the subject or other reason that in the judgement of the investigator(s) makes the subject unsuitable for participation in the study.
