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

March 10, 2026 updated by: Peking Union Medical College Hospital
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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Description

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.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Patients（Experimental）
Patients with neurodegenerative diseases will receive a single intravenous injection of the investigational PET tracer 18F-FCOB04 followed by PET/CT imaging for evaluation of biodistribution and lesion uptake.
Drug: 18F-FCOB04
Single intravenous administration of the investigational PET radiotracer 18F-FCOB04 followed by PET/CT imaging for evaluation of safety, biodistribution, radiation dosimetry, and target-specific uptake.
Experimental: Healthy Volunteers
Healthy participants will receive a single intravenous injection of the investigational PET tracer 18F-FCOB04 followed by PET/CT imaging for safety and dosimetry assessment.
Drug: 18F-FCOB04
Single intravenous administration of the investigational PET radiotracer 18F-FCOB04 followed by PET/CT imaging for evaluation of safety, biodistribution, radiation dosimetry, and target-specific uptake.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Regional standardized uptake value ratio (SUVR) on 18F-FCOB04 PET
Time Frame: Baseline (Day 1, at the time of 18F-FCOB04 PET imaging)
Regional standardized uptake value ratio (SUVR) measured on 18F-FCOB04 positron emission tomography (PET) images. SUVR is defined as the ratio of tracer uptake in a predefined target brain region to uptake in a predefined reference region. The measurement unit is unitless. SUVR will be calculated using PET image analysis software based on predefined regions of interest.
Baseline (Day 1, at the time of 18F-FCOB04 PET imaging)

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
