About this study
Official title: Clinical Study of Domestic Polysaccharide Superparamagnetic Iron Oxide Nanoparticle Injection for Renal Contrast-enhanced Magnetic Resonance Imaging
Conventional contrast-enhanced magnetic resonance imaging is typically performed with extracellular gadolinium chelates, which is often limited in patients with CKD owing to the risk of nephrogenic systemic fibrosis. Ferumoxytol, a novel contrast medium, can be used as an "off-label" contrast agent for magnetic resonance imaging. During the last decade, ferumoxytol has gained appeal as an MRI contrast agent in patients with estimated glomerular filtration rates <30mL/min and there are reports in the literature for its safe use and utility in both adult and pediatric patients with CKD. The study is designed to evaluate the diagnostic performance of ferumoxytol-enhanced magnetic resonance imaging in patients suspected of renal artery stenosis, investigate the correlation between renal cortical T2*(T2*=1/R2*) and renal function, and develop an automatic algorithms for renal vessel segmentation.
Read the detailed description
This study is a single-center, prospective, controlled and diagnostic clinical trial to evaluate renal vasculature and renal function with ferumoxytol-enhanced magnetic resonance imaging using domestic polysaccharide superparamagnetic iron oxide injection as the contrast agent. This study will enroll 40 patients with or without renal impairment that are expected to undergo renal artery angiography in China. The investigators will record the baseline data of patients after admission. Patients will receive enhanced renal magnetic resonance imaging with polysaccharide superparamagnetic iron oxide nanoparticle to assess renal vasculature and renal function. The related laboratory indices will be reviewed at 24-72 h after magnetic resonance imaging, and then patients will receive renal angiography. The indices will be reexamined at 1 month and 3 months after magnetic resonance imaging. In order to evaluate the safety of polysaccharide superparamagnetic iron oxide nanoparticle, patients will detect iron levels in peripheral and tissue before and after the examination. The results of MR imaging including image quality, degree of vascular stenosis, and quantitative T2* values of the renal cortex will be evaluated independently by two experienced radiologists. The degree of stenosis of the same vessels assessed by Quantitative Coronary Analysis (QCA) will be used for comparison with MR results. All clinical adverse events will be recorded by investigators.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing domestic polysaccharide superparamagnetic iron oxide nanoparticle in people with Chronic Kidney Diseases, run by The First Affiliated Hospital with Nanjing Medical 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 4 inclusion and 10 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 25 Sep 2024. 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.
What does this phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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?
the degree of renal artery stenosis (time frame: baseline and after intervention). The study lists 12 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 25 Sep 2024.
