Eligibility Criteria

1 Year - undefined (Child, Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Subject or his/her parents or legal guardian in case of minors, does not understand the study procedure
  • Subject is unwilling or unable to perform all of the study procedures, or is considered unsuitable in any way by the principal investigator.

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Patients

Arm Description

A single dose of 18F-MFBG will be intravenously injected in 10 patients with neural crest tumors or neuroendocrine tumors. Adult patients will first undergo a dynamic PET scan, followed by whole-body PET/CT scans at various time points for a pharmacokinetics study and efficacy assessment. Pediatric patients will undergo, depending on what is feasible for the child, at least 1 and up to 2 static whole-body PET/CTs. In patients 12 years or older, also a dynamic PET scan can be performed.

Outcomes

Primary Outcome Measures

Confirmation of 18F-MFBG as a hNET imaging agent in patients with neural crest and neuroendocrine tumors.
The primary endpoint will be met if in 8 out of 10 patients, at least 80% of the known positive lesions on 123I-MIBG imaging is visualized.

Secondary Outcome Measures

Normal-organ and tumor uptake of 18F-MFBG as a function of time
Patients will undergo dynamic PET scanning followed by three static whole-body PET/CT scans at different time points post injection. Uptake as a function of time (pharmacokinetics) will be studied using the software package PMOD (PMOD technologies LLC, Zürich, Switzerland). Volumes of interest (VOIs) will be delineated in relevant normal organs and tumor lesions on all PET images and standardized uptake values (SUV) in all these VOIs will be measured to compute normal-organ and tumor uptake as a function of time.
Identify the ideal time point for imaging after 18F-MFBG injection.
Tumor-to-background ratios as a function of time will be measured. The time point resulting in optimal tumor-to-background ratios, taking into account a realistic implementation in clinical practice, will be defined as the ideal time point for imaging.
Safety analysis of 18F-MFBG administration: Common Terminology Criteria for Adverse Events (CTCAE) version 4.03
The impact of 18F-MFBG administration on clinical symptoms and signs and biochemistry values will be evaluated. Baseline values will be recorded and subjects will be assessed clinically and with serial biochemical analysis. Adverse events will be scored according to the Common Terminology Criteria for Adverse Events (CTCAE) version 4.03.
Assessment of lesion targeting by 18F-MFBG as compared to 123I-MIBG
A lesion-by-lesion analysis (visual and semi-quantitative) will be performed to compare the number of detected lesions using both tracers.

5. Study Description

Brief Summary
The aim of this study is to evaluate the potential and feasibility of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients with neural crest and neuroendocrine tumors.
Detailed Description
Ten neural crest tumor or neuroendocrine tumor (NET) patients, with a routine clinical 123I-metaiodobenzylguanidine (123I-MIBG imaging) (planar + single photon emission tomography (SPECT)) performed in the previous six months or scheduled within three months, will undergo a dynamic PET scan for the first 30 minutes, followed by 3 static whole-body PET/CTs up to three hours post injection for a pharmacokinetics study and efficacy assessment of 18F-MFBG in humans. Furthermore, a comparison with 123I-MIBG imaging will be performed.
