Clinical Applications of (S)-[18F]FBFP PET/CT in Healthy Volunteers and Patients With Central Nervous System Diseases
- Conditions
- Patients With Central Nervous System Diseases
- Interventions
- Diagnostic Test: (S)-[18F]FBFP PET/CT
- Registration Number
- NCT05335200
- Lead Sponsor
- Peking Union Medical College Hospital
- Brief Summary
This is an open-label whole-body PET/CT (positron emission tomography/computed tomography) study for investigation of radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of (S)-\[18F\]FBFP in healthy volunteers and patients with central nervous system diseases. A single dose of nearly 370 MBq (S)-\[18F\]FBFP will be intravenously injected into healthy volunteers and patients with central nervous system diseases. Visual and semiquantitative method will be used to assess the PET/CT images. Changes of blood pressure, pulse, respiration, temperature and any adverse events will be collected from the volunteers. Adverse events will also be observed in the patients.
- Detailed Description
(S)-\[18F\]FBFP is a promising sigma-1 receptor radioligand. The sigma-1 receptor is a unique chaperone protein with 223 amino acids located at the mitochondria-associated endoplasmic reticulum membrane. Several lines of evidence have demonstrated that the sigma-1 receptor plays a pivotal role in the pathophysiology of many neuropsychiatric disorders including amyotrophic lateral sclerosis, Alzheimer's disease, Parkinson's disease, Huntington's disease, pain, depression and drug addiction.Therefore, it is an important target for the investigation of neuropsychiatric disorders and drug development. PET imaging of sigma-1 receptors in the human brain will enable the elucidation of this target's involvement in neurologic disorders and will also facilitate new drug development.
For further interests in clinical translation of PET sigma-1 receptors radioligands, (S)-\[18F\]FBFP, an open-label whole-body PET/CT study was designed to investigate radiation dosimetry, plasma pharmacokinetics, biodistribution, safety and diagnostic performance of (S)-\[18F\]FBFP in healthy volunteers and patients with central nervous system diseases.

Group Intervention Description (S)-[18F]FBFP injection and PET/CT scan (S)-[18F]FBFP PET/CT Patients will be intravenously injected with(S)-\[18F\]FBFP and undergo PET/CT scan.
- Primary Outcome Measures
Name Time Method Visual and semiquantitative assessment of organs and biodistribution 1 month Visual analysis will be performed by consensus reading by at least 3 experienced nuclear medicine physician. The semiquantitative analysis will be performed by the same person for all the cases, and the standardized uptake values (SUVs) of lesions or organs will be measured.
- Secondary Outcome Measures
Name Time Method Adverse events collection 1 week Adverse events within 1 week after the injection and scanning of patients and patients will be followed and assessed
