Study on the Application of ¹⁸F-FCOB04, a MAO-B Targeted PET Imaging Agent, in Neurodegenerative Diseases

Starting soon · Early Phase 1

Conditions studied: Neurodegenerative Diseases

In brief

In this clinical trial, we intend to perform 18F-FCOB04 PET imaging in patients with neurodegenerative diseases to observe the brain uptake of this tracer.We will investigate the distinct imaging patterns of brain MAO-B expression in patients with various neurodegenerative diseases.Correlation analysis will be conducted between imaging findings and relevant clinical indicators.This study aims to evaluate the role of 18F-FCOB04 in the auxiliary diagnosis of neurodegenerative diseases, as well as to assess the tolerability and safety of the tracer and the imaging procedure.

Who can join

Age: 18 and older, up to 75. Sex: any. Healthy volunteers: accepted.

You may qualify if…

• Aged between 18 and 75 years, regardless of gender.
• Patients diagnosed with probable or possible neurodegenerative diseases by a specialist neurologist according to current internationally recognized clinical diagnostic criteria, including but not limited to Alzheimer's disease, Parkinson's disease, and Parkinsonian syndromes (such as progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, etc.).Diagnosis is based on a comprehensive evaluation including systematic medical history collection, neurological examination, relevant neuropsychological or motor function scale assessments, combined with conventional structural neuroimaging such as cranial MRI.Patients with a history of brain surgery, brain cyst, brain tumor, or other comorbidities that may affect data analysis are excluded.
• Prior to any assessment, the subject or their legal representative has understood and signed the written informed consent form.
• Subjects who are currently using, or have not used MAO-B inhibitors (including but not limited to selegiline, rasagiline, safinamide) for ≥14 days prior to enrollment.

You may not qualify if…

• Suffering from other severe neurological diseases, or severe diseases of the gastrointestinal, cardiovascular, hepatic, renal, hematological, oncological, endocrine, respiratory, immunodeficiency or other severe systemic disorders.
• Suffering from claustrophobia.
• History of substance abuse or excessive alcohol consumption.
• Female subjects who are pregnant or breastfeeding.
• Presence of any condition that, in the opinion of the investigator, may be harmful or potentially harmful to the subject in any procedure related to this study.
