About this study

Official title: VCRC Longitudinal Protocol for Takayasu's Arteritis

Takayasu's arteritis is a rare disorder that causes swelling and damage to the large arteries in the body, such as the aorta. In order to ensure proper treatment, measuring disease activity is critical. The purpose of this study is to establish new biological markers (biomarkers) to assess the severity of disease in people with Takayasu's arteritis.

Read the detailed description

Takayasu's arteritis is a chronic inflammatory condition that affects the aorta, the largest blood vessel in the body, and its branches. Inflammation causes segments of the vessels to become narrowed, blocked, or even stretched, possibly resulting in aneurysms. The disease is very rare but most commonly occurs in young Asian women. Symptoms may include arm pain with use, decreased or absent pulses, lightheadedness or dizziness, headaches, and visual disturbances. Many individuals with Takayasu' arteritis, however, have no apparent symptoms despite disease activity. Additionally, current tests used to measure vessel inflammation are considered unreliable and inconsistent. It is therefore very difficult to determine the extent of disease activity in a person with Takayasu's arteritis. This study will use novel scientific methods to establish new biomarkers that can be used to monitor disease activity in individuals with Takayasu's arteritis. These biomarkers may be used to help direct clinical care and assist in future drug development.

Study visits will occur monthly for the first year, then every 3 months thereafter for the remainder of the study. Blood and urine collection will occur at every visit. A physical examination, disease assessment, and review of medications will occur every 3 months; participants may also be asked to complete various questionnaires. Diagnostic testing, which may include chest radiograph, echocardiogram, magnetic resonance imaging, or angiography, will occur every 6 months. Tobacco, alcohol, and drug use will be assessed on a yearly basis. Participants may have additional study visits if a disease flare or disease-related complications occur during the study.

An observational study of Takayasu's Arteritis, run by University of Pennsylvania at 9 sites in 2 countries.

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 8 inclusion and 8 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 12 Jul 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Canada. 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?

Discover biomarkers in Takayasu's arteritis capable of measuring disease activity and response to treatment. (time frame: Study completion). 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 NCT00315471, 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 12 Jul 2022.
