About this study

The purpose of this study is to detect the association between RNF213 variants and collateral vessels in patients with moyamoya disease.

Read the detailed description

Moyamoya disease (MMD) is a chronic cerebrovascular disorder characterized by the presence of occlusion which occurs at the internal carotid arteries and their main branches during the development of a basal collateral network. The ring finger 213 (RNF213) was identified as a strong susceptibility gene in patients with MMD in East Asia. The role of RNF213 variants in pathogenesis of MMD is still unclear. Specific "moyamoya vessels" correlate with the onset of stroke. The purpose of this study is to investigate the relationship between RNF213 variants and collateral vessels in patients with moyamoya disease, and provide potential pathogenesis of moyamoya disease.

Questions about this trial

What is this clinical trial studying?

An observational study of Moyamoya Disease, run by Beijing Tiantan Hospital 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 3 inclusion and 3 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: finished, as of the sponsor's last update on 17 Feb 2022. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Identification of RNF213 variants and different types of collateral vessels (time frame: Baseline). 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 17 Feb 2022.
