Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 5 to 65 years
  • All sexes
  • No healthy volunteers
  • Child, Adult, Older adult

Study population: The study population will be comprised of male and female subjects ≥ 5 years of age, with or without existing Alport genotyping, regardless of specific genotype, and who meet all other eligibility criteria. Subjects with existing Alport genotyping are preferred. Alport subjects will be enrolled via ASTOR, and healthy volunteers will be enrolled elsewhere, outside the scope of this protocol. Approximately 80 Alport syndrome subjects will be enrolled in this study. Of the 80 subjects, 75% (N = 60) should have non-postural, non-nephrotic proteinuria (defined as spot urine protein-to-creatinine ratio < 3 on at least 2 of the last 3 clinical assessments).

Who may be able to join

  • Subjects eligible for inclusion in this study have to fulfill all of the following criteria:
  • Able to understand and comply with the requirements of the study and able to provide written informed consent.
  • Male and female subjects ≥ 5 years of age.
  • Physically able to provide a single first-morning urine sample of at least 30 mL (one ounce).
  • Alport syndrome diagnosis: Clinical and/or histopathologic and/or genetic diagnosis of Alport Syndrome, as per the subject's physician and/or genotyping.

Who cannot join

  • Subjects fulfilling any of the following criteria are not eligible for inclusion in this study:
  • Use of investigational drugs at the time of enrollment, or within 30 days or 5 half-lives of enrollment, whichever is longer; or longer if required by local regulations, and for any other limitation of participation in an investigational trial based on local regulations.
  • Chronic kidney disease, defined as a known diagnosis of CKD, and/or receiving chronic phosphate-lowering therapy or erythropoietin therapy.
  • Ongoing chronic hemodialysis therapy and/or renal transplant recipient.
  • Nephrotic-range proteinuria: spot urine protein-to-creatinine ratio ≥ 3 on at least 2 of the last 3 clinical assessments.

About this study

The purpose of the study is to determine if there are certain laboratory tests that can be performed to detect substances or features in a child's urine that can be used to measure the progress of Alport kidney disease and the effects of treatment. These tests and their results could be of use to measure responses to new treatments in future clinical trials.

Read the detailed description

This is a prospective cross-sectional, observational, single-center study of affected Alport patients who have not progressed to advanced chronic renal insufficiency (CKD Stages 4 or 5), and who do not have nephrotic range proteinuria (urine protein-to-creatinine ratio > 3). There will be no required study site visits. Instead, encounters will occur via telephone with subjects when they are at home. This study consists of a single, first morning voided urine collection for subjects who meet eligibility criteria. Eligibility criteria and informed consent can be obtained via telephone in order to be as non-intrusive to the subject as possible.

Alport subjects will be recruited via the Alport Syndrome Treatments and Outcome Registry (ASTOR, University of Minnesota). ASTOR is the largest Alport Syndrome registry in the USA, comprised of approximately 500 people affected by Alport Syndrome. Subjects who meet eligibility criteria will be asked to provide clinical and demographic information and a single urine sample. A portion of the de-identified sample will be sent to Covance Laboratories for processing for Novartis and the remainder will be processed, stored and analyzed at the University of Minnesota. Subjects who provide consent will be given a kit and instructions for collecting the urine sample. Kits will then be returned via overnight courier to the study site. ASTOR study personnel will then communicate with subjects via the telephone to confirm proper first-morning void collection technique, and to obtain clinical historical information.

Approximately 80 Alport subjects will be enrolled in this study via ASTOR. Of the 80 Alport subjects, approximately 25% (N = 20) should have no significant proteinuria (spot urine protein-to-creatinine ratio ≤ 0.2), and approximately 75% (N = 60) should have non-postural, non-nephrotic proteinuria (defined as spot urine protein-to-creatinine ratio > 0.2 and < 3 on at least 2 of the last 3 clinical assessments). Approximately 40 healthy volunteers will provide urine samples elsewhere, outside the scope of this protocol. Healthy volunteer urine samples need not be first-morning voided specimens, however each specimen will be screened via dipstick for semi-quantitative protein analysis. Only samples with negative or trace protein on dipstick will be included in the study.

Informed consent forms will be included in the kit sent to each eligible Alport subject. Informed consent will take place via telephone, and preferably via video chat/Skype whenever possible.

What is being measured

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

  1. Urine levels of biomarkers, corrected for urine creatinine, in Alport subjects stratified by magnitude of proteinura.

    Measured: This is a cross-sectional study. Subjects will submit a single urine sample (Day 1).

Questions about this trial

What is this clinical trial studying?

An observational study of Alport Syndrome, run by University of Minnesota 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 5 inclusion and 5 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 30 Jul 2013. 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?

Urine levels of biomarkers, corrected for urine creatinine, in Alport subjects stratified by magnitude of proteinura. (time frame: This is a cross-sectional study. Subjects will submit a single urine sample (Day 1).). 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 30 Jul 2013.
