  2. Advanced vascular occlusive disease (atherosclerosis) affecting one or both kidneys: defined as a) loss of parenchymal volume and renal blood flow (measured by MDCT as previously described (17) and/or duplex ultrasound velocity above 300 cm/sec to the affected kidney to be infused with MSC's.
  3. Have serum creatinine below 2.5 mg/dL

About this study

Official title: Phase I Study of Autologous Mesenchymal Stem Cells in the Treatment of Atherosclerotic Renal Artery Stenosis

Read the detailed description

Individuals with unilateral arterial occlusive disease will be treated to injured kidney with autologous cells.

Study groups in NCT01840540
Study groupRoleWhat they receive
infusion of autologous mesenchymal stem cellsExperimentalPatients will undergo a subcutaneous fat biopsy for expansion of mesenchymal stromal (stem) cells (MSC) in the Human Cell Therapy Laboratory. Patients will be admitted to the inpatient Clinical Research Unit of the Mayo Clinic Center for 3 days prior to treatment, for pre-infusion tests. Renal angiography will be performed to deliver a single intra-arterial dose of MSC's into one affected kidney. Patients will be observed for 24 hours for acute adverse events. Patients will have remote visits at 1 week, 4 weeks,8 weeks, and 6 months. At 3 months, patients will return for repeat evaluation of kidney function, blood flow and structural alterations within the clinical research unit at St. Mary's Hospital, Rochester, Minnesota. Thereafter, health assessment and blood draws will be repeated at 12 and 24 months with urinary cytology and MRI.
Receives: Drug: Arterial infusion of autologous mesenchymal stem cells

What is being measured

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

  1. Renal blood flow and function in the treated kidneys.

    Individual kidney blood flow, measured by multidetector CT contrast transit times, will be measured before and after MSC infusion.

    Measured: 2 years

Secondary outcomes (1)
  1. Level of kidney function.

    Level of kidney function will be assessed as glomerular filtration rate by iothalamate clearance. Tissue oxygenation within each kidney will be measured by Blood Oxygen Level Dependent (BOLD) magnetic resonance.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Arterial infusion of autologous mesenchymal stem cells in people with Atherosclerotic Renal Artery Stenosis and Ischemic Nephropathy, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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 7 Aug 2017. 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 United States. 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?

Renal blood flow and function in the treated kidneys. (time frame: 2 years). 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 NCT01840540, which also lists 1 linked publication.

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 7 Aug 2017.
