About this study

Official title: The Chinese Parkinson's Disease With GBA Variants Registry

The purpose of the Chinese Parkinson's disease with GBA variants Registry (CPD-GBAR) is to develop a database of patients of Parkinson's disease with Glucocerebrosidase (GBA) gene variants in mainland China.

Read the detailed description

Parkinson's disease (PD) is the second most common disorder among neurodegenerative diseases. GBA gene variants such as L444P can influence the risk of developing PD and these variants have the greatest impact on PD susceptibility among all the PD related gene variants yet discovered. The investigators aim to establish a database of PD with GBA variants and characterize the clinical manifestation of these patients in mainland China.

Method:

  1. Peripheral blood from patients has been tested to have GBA gene variants.
  2. Clinical manifestation will be measured by scales and neurological tests. Standard scales include: Unified Parkinson's Disease Rating Scale(UPDRS), Hoehn-Yahr stages, Non-Motor Symptoms Scale (NMSS), mini-mental state examination (MMSE), Parkinson disease sleep scales (PDSS), Rapid Eye Movement Sleep Behaviour Disorder Questionnaire(RBDQ-HK), Epworth Sleepiness Scale (ESS), Rome III functional constipation scale, the Scale for Outcomes in PD for Autonomic Symptoms (SCOPA-AUT), Parkinson Fatigue Scale (PFS), Cambridge-Hopkins Restless Legs Syndrome questionnaire (CHRLSq), Hyposmia rating scale(HRS), Hamilton depression scale, the 39-item Parkinson's Disease Questionnaire(PDQ-39), Freezing of gait scale(FOG), dyskinesia related scales, Wearing-off scale(WO).
  3. The investigators will also exam the blood biomarkers of PD such as uric acid and peripheral inflammatory markers.

Questions about this trial

What is this clinical trial studying?

An observational study of Parkinson Disease, run by Xiangya Hospital of Central South University at 1 site 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 1 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: looking for participants now, as of the sponsor's last update on 29 May 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

This study is still under way. Results are not available in the source record yet.

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

Contact Jifeng Guo, Ph.D. (+8613974936815, guojifeng2003@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Database of Parkinson's disease with GBA variants (time frame: 10 years). 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?

On the ClinicalTrials.gov record for NCT03523065, which also lists 5 linked publications.

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 29 May 2018; AzTrials last refreshed its copy on 3 Nov 2026.
