18F-mFBG LAFOV PET/CT Compared to 123I-mIBG Scintigraphy SPECT/CT for Evaluation of Children With Neuroblastoma

Study Purpose

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

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	N/A - 18 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. An established diagnosis of neuroblastoma based on unequivocal histopathology from tissue obtained at any time prior to enrolment in the trial; OR b) A presumed diagnosis of neuroblastoma based on signs, symptoms, physical examination, imaging findings, and laboratory and genetic test results, including individuals in whom therapy has already been empirically initiated. 2. The subject has undergone or is scheduled to undergo evaluation of neuroblastoma disease status, including 123I-mIBG +/- 7 days to the date of 18F-mFBG imaging, with no therapy between such evaluation. 3. Ability of subject or subject's legal guardian to understand and sign a written informed consent document.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05826158
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3
Lead Sponsor The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.	Rigshospitalet, Denmark

Additional Details

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.
