18F-mFBG PET Imaging in the Evaluation of Neuroblastoma

Study Purpose

The aim of this study is to evaluate the diagnostic performance and tumor burden of 18F-metafluorobenzylguanidine (18F-MFBG) positron emission tomography (PET) in patients with 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.	Observational
Eligible Ages	N/A - 18 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Age 0-18 years old, with legal guardian; 2. Clinically suspected or confirmed patients with neuroblastoma; 3. If the patient is under 8 years old or unable to write, his/her guardian should understand and comply with the requirements of the study. If the patient is 8 years old or older and has written ability, both the patient and his/her guardian must sign the informed consent.

Exclusion Criteria:

1. Patients with severe primary diseases such as heart, brain, liver, kidney and hematopoietic system diseases; 2. Patients who have received ionizing radiation outside the scope of this experiment for other clinical medical or scientific research purposes within the past year, resulting in an annual radiation exposure dose exceeding 50 mSv. 3. Patients who have received experimental drugs or devices (with uncertain efficacy or safety) within one month; 4. Patients with any condition that the principal investigator of this study deems may cause harm or potential harm in any aspect related to this trial.

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.	NCT06852807
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.

Additional Details

Neuroblastoma highly expresses norepinephrine transporter (NET) which is targeted by function alanalogue of norepinephrine, 123/131I-MlBG. However, low spatial resolution of 123/131I-MlBG and inaccurate attenuation correction of single photon emission tomography (SPECT/CT) will affect the image quality of MlBG SPECT and lead to poor diagnosis of small lesions. In addition, 123l-MlBG imaging is usually performed at 24h after injection, while 131I-MlBG is performed at 48h or even 72h after injection. The procedure is complicated and takes a long time, which limits clinical application. 18F-labeled MFBG is an ideal tracer to show the expression of NET. Preliminary data show that 18F-MFBG imaging is safe and has favorable biodistribution and kinetics with good targeting of lesions. Patients can undergo PET 0.5 hours after injection without special preparation. Our study will assess the safety profile, image quality and evaluate the diagnostic performance and tumor burden of 18F-MFBG. Patients with suspected or histologically confirmed neuroblastoma will be enrolled in this study.

Arms & Interventions

Arms

: 18F-MFBG PET/CT in Neuroblastoma

Each patient receive a single intravenous injection of 18F-MFBG 2-5 MBq/kg and undergo PET/CT or PET/MR scan after 60 min post-injection.

Interventions

Drug: - 18F-MFBG

Patients with neuroblastoma malignancies receive 5.55 MBq/kg of 18F-MFBG intravenously followed by PET/CT or PET/MR after 60min of injection.
