New brain scan tracer could spot Alzheimer's and Parkinson's earlier
NCT ID NCT07470710
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-phase trial will test a new radioactive tracer called 18F-FCOB04 in 40 people with neurodegenerative diseases like Alzheimer's or Parkinson's. The tracer targets a brain protein called MAO-B and is used with PET scans to see if it can help diagnose these conditions. The study focuses on safety and how the tracer behaves in the body.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- 18F-FCOB04 (a radioactive tracer for PET imaging)
- What this could lead to
- If successful, this could lead to a new imaging tool to help doctors diagnose neurodegenerative diseases more accurately and earlier.
- What could go wrong
- This is a very early, small study (40 people) focused on safety and imaging patterns, not treatment. It may not lead to a widely used diagnostic test.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Aged between 18 and 75 years, regardless of gender. 2. 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. 3. Prior to any assessment, the subject or their legal representative has understood and signed the written informed consent form. 4. 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. Exclusion Criteria: 1. 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. 2. Suffering from claustrophobia. 3. History of substance abuse or excessive alcohol consumption. 4. Female subjects who are pregnant or breastfeeding. 5. 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.
