About this study

Official title: Pilot and Feasibility Study: Evaluation of New Quantitative Magnetic Resonance Imaging Parameters in Assessing the Kidneys of Autosomal Dominant Polycystic Kidney Disease

The purpose of this study is to establish normal Magnetic Resonance quantitative values (tissues stiffness, Apparent Diffusion Coefficient values and Blood Oxygen Level Determination values for both renal cortex and medullary tissues and total renal blood flow) for young Autosomal Dominant Polycystic Kidney Disease patients with normal renal function, and normal young adult controls without Autosomal Dominant Polycystic Kidney Disease and normal renal function.

Hypothesis: Newer Magnetic Resonance quantitative imaging parameters (tissue stiffness, Apparent Diffusion Coefficient, Blood Oxygen Level Determination levels, Magnetization Transfer and renal blood flow) will have different values in young adult ADPKD patients as compared to normal volunteers.

What is being measured

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

  1. Evaluate renal tissue stiffness

    The renal parenchymal tissue stiffness is measured in kilopascals with magnetic resonance elastography sequence.

    Measured: baseline

  2. Magnetization transfer ratio

    The magnetization transfer ratio of renal tissue is measured with magnetization transfer sequence and expressed as a ratio.

    Measured: baseline

  3. Diffusion

    Diffusion is quantified as apparent diffusion coefficient (x10-3/mm2) in renal tissue is measured with intravoxel incoherent motion imaging (IVIM) sequence and diffusion tensor imaging (DTI).

    Measured: baseline

  4. Perfusion quantified as blood flow in mL/s.

    Perfusion in the renal tissue is measured with arterial spin labeling sequence and phase contrast magnetic resonance angiography.

    Measured: baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Autosomal Dominant Polycystic Kidney Disease and Kidney Disease, 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?

The sponsor lists 7 inclusion and 13 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 Jun 2016. 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.

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?

Evaluate renal tissue stiffness (time frame: baseline). The study lists 4 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 17 Jun 2016.
