  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Patients with Parkinson's disease and parkinsonian dementia syndromes
  • Males and females, ≥40 years old
  • The diagnosis of PD is established using the UK Parkinson's Disease Society Brain Bank Research Center Clinical diagnostic criteria. Criteria for PD-MCI and PD-dementia are consistent with those of the Movement Disorder Society. The DLB Consortium consensus criteria are used for DLB.
  • They rely on a combination of neurologic examination and neuropsychological assessment with a battery of tests. Clinical diagnosis was established by sophisticated neurologists.

Who cannot join

  • Females planning to bear a child recently or with childbearing potential
  • Renal function: serum creatinine >3.0 mg/dL (270 μM/L)
  • Liver function: any hepatic enzyme level more than 5 times upper limit of normal.
  • Known severe allergy or hypersensitivity to IV radiographic contrast.
  • Patients not able to enter the bore of the PET/CT scanner.
  • Inability to lie still for the entire imaging time because of cough, pain, etc.
Show all 9Show fewer
  • Inability to complete the needed examinations due to severe claustrophobia, radiation phobia, etc.
  • Concurrent severe and/or uncontrolled and/or unstable other medical disease that, in the opinion of the Investigator, may significantly interfere with study compliance.

About this study

Official title: Safety and Diagnostic Performance of 11C-PIB PET/CT in Patients With Parkinson's Disease and Parkinsonian Dementia Syndromes

To evaluate the potential contribution of amyloid burden, as indexed by 11C-Pittsburgh compound B (PiB) retention, to the progression of cognitive impairments in patients with Parkinson's disease(PD).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Amyloid burden range in all subjects

    Outcome Measures: All patients underwent a 90-min dynamic 11C-PIB PET scan. 11C-PiB distribution volume ratio (DVR) will be estimated by using the PMOD software.

    Measured: 1 week

Secondary outcomes (1)
  1. The cognitive scores in all patients

    Functional status is assessed by the Mini-Mental State Examination (MMSE). Parkinson disease with mild cognitive impairment:MMSE score 24-28; Parkinson disease with dementia: MMSE score ≤24; Parkinson disease with normal cognition: MMSE score >28.

    Measured: 0, 6month, 1year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing 11C-PiB in people with Parkinson Disease, run by Oriental Neurosurgery Evidence-Based-Study Team at 3 sites in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 13 Jun 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Li Cai, PhD (86-22-60362190, XCL242004@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Amyloid burden range in all subjects (time frame: 1 week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jun 2018.
