Trial summary

Blood will be harvested from three groups of people, normal control, patients with mild cognitive impairment (MCI) and patients with Alzheimer's disease (AD), 20 people per group. The blood samples will be used to determine the difference in the expression of microRNAs and proteins. Read more about this study

About this study

Official title: Screen and Verification of Biomarkers for Early Detection of Alzheimer's Disease

Blood will be harvested from three groups of people, normal control, patients with mild cognitive impairment (MCI) and patients with Alzheimer's disease (AD), 20 people per group. The blood samples will be used to determine the difference in the expression of microRNAs and proteins. Blood samples will be harvested again at 6-month interval from patients. The combination of the microRNAs and proteins that have different expression patterns between normal control and patients with MCI will be constructed in a kit to detect the difference. This kit will be used in another set of the three groups of people to determine its sensitivity and specificity in detecting patients with MCI.

Read the detailed description

As discussed above, patients' blood samples will be tested by chip to test microRNA expression and liquid chromatography-mass spectrometry to determine protein expression. The differences in microRNA and protein expression among the three groups, especially between the control and MCI, will be analyzed. This information will be used to construct a kit that can contain probes to detect a few microRNAs or proteins. This kit will be used in another set of patients to check its sensitivity and specificity. The first set of patients will also be followed up every 6 months for up to 1.5 years. Blood samples will be harvested during the follow-ups. The changes in microRNAs and proteins will be correlated with the changes of cognition. This information will be used for constructing the kit as well.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • No interventionOther

    Patients will be recruited into the study in their initial visit before patients are on any drug treatments for their AD or MCI. The study does not include use of any interventions.

What is being measured

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

  1. Fold changes of microRNAs in the blood of Patients with MCI over control people.

    serum and plasma will be used in the screen.

    Measured: Patients with MCI and AD will be evaluated every 6 month for 1.5 years to monitor the changes in their cognition and the expression patterns of microRNAs and proteins.

  2. Fold changes of proteins in the blood of Patients with MCI over control people.

    serum and plasma will be used in the screen.

    Measured: Patients with MCI and AD will be evaluated every 6 month for 1.5 years to monitor the changes in their cognition and the expression patterns of microRNAs and proteins.

Questions about this trial

What is this clinical trial studying?

An observational study of Mild Cognitive Impairment, run by Sun Yat-sen University at 2 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 1 inclusion and 4 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: withdrawn, as of the sponsor's last update on 23 Jun 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fold changes of microRNAs in the blood of Patients with MCI over control people. (time frame: Patients with MCI and AD will be evaluated every 6 month for 1.5 years to monitor the changes in their cognition and the expression patterns of microRNAs and proteins.). The study lists 2 primary outcomes in all. 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 23 Jun 2023.
