Clinical Trial Summary

This is a study evaluating the positron-emitting radiopharmaceutical 18F-mFBG compared to 123I-mIBG scintigraphy for imaging of neuroblastoma


Clinical Trial Description

This is a prospective study designed to assess the use of 18F-mFBG PET imaging compared to 123I-mIBG scintigraphy in subjects with known or presumed neuroblastoma. Eligible participants will have either histopathologically established diagnosis of neuroblastoma or a presumed diagnosis based on signs, symptoms, physical examination, imaging findings, and laboratory and genetic test results. Subjects will only be administered 18F-mFBG if they have undergone or are scheduled to undergo a 123I-mIBG within +/- 7 days of the date of the 18F-mFBG scan. Subjects should not have received any chemotherapy, immunotherapy or radiotherapy between the clinical and 18F-mFBG imaging studies. 18F-mFBG PET studies will be evaluated by 2 independent teams of blinded readers: a nuclear medicine physician and a radiologist, both specialized in pediatric nuclear medicine co-reading side-by side. The clinical 123I-mIBG is also evaluated by 2 independent teams of blinded readers: a nuclear medicine physician and a radiologist, both specialized in pediatric nuclear medicine co-reading side-by side. Blinded readers will record whether findings on 18F-mFBG and 123I-mIBG scans are consistent with neuroblastoma. Subject-level diagnostic performance will be assessed on the basis of differencies in lesion-counting between the blinded 18F-mFBG scan interpretation and the 123I-mIBG scan. In case of discrepancy, independently assessed by an Expert Panel. ;
