About this study

Official title: Transcriptional Profiling of Kidney Tissue Obtained From Patients With Newly Identified Proteinuria, Nephrotic Syndrome or Nephritic Syndrome

This study will evaluate in patients with kidney disease, the role that certain inflammatory and immune mediators play in promoting kidney damage. The investigators hypothesize that certain mediators, (identified in the serum, urine and renal biopsy tissue), of patients with a variety of different renal disease states will provide information regarding their clinical course and that inflammatory and immune patterns in the serum and urine of patients with kidney disease may yield predictive diagnostic information in place of a renal biopsy. The ability to detect and quantify these mediators may lead to earlier detection and treatment of kidney disease in order to prevent kidney failure and the requirement for renal replacement.

The study will evaluate serum, blood and urine collected over a one year period post kidney biopsy for the presence of inflammatory or immune mediators, which will be correlated with kidney pathology findings (gene signatures). These gene signatures will be compared to "normal" control specimens obtained from donor transplant kidneys or from normal kidney tissue obtained from patients who require their entire kidney removed for a tumor.

Read the detailed description

The aim of the study is to evaluate in humans inflammatory and immune mediators that may play a role in kidney damage. The investigators hypothesize that certain inflammatory and immune mediators identified in the serum and/or urine of patients with a variety of different renal disease states will provide prognostic information regarding their clinical course. Furthermore, we hypothesize that RNA transcriptional profiling of renal biopsy specimens will identify gene array patterns that provide prognostic information for various disease states. Lastly, we hypothesize that patterns of inflammatory and immune mediators identified in serum and/or urine may yield predictive diagnostic information in lieu of renal biopsy. The ability to detect and quantify these mediators may lead to earlier detection and treatment prior to the progression of Chronic Kidney Disease (CKD) to stage 4 and/or 5.

The study will evaluate serially collected serum, blood and urine over a one-year period post kidney biopsy for both the presence of inflammatory or immune mediators. The blood, serum and urine inflammatory and immune mediators will be correlated with the kidney pathology gene signature. Note that all of the biopsies are conducted based upon clinical indication and not for the purpose of the study.

Renal pathology gene signatures obtained from study subjects will be compared to "normal" control specimens. Normal specimens will be obtained from donor transplant kidneys or nephrectomy specimens performed on patients undergoing nephrectomy for the clinical indication of an identified renal mass. Representative "normal" tissue will be obtained from the nephrectomized kidney at a site distant from the renal mass.

Study groups in NCT01156428
Study groupRoleWhat they receive
Control Subjects (normal volunteers)Control kidney specimens will be obtained from donor transplant kidneys or nephrectomy specimens performed on patients undergoing nephrectomy for the clinical indication of an identified renal mass. In the case of donor transplant kidneys, the renal biopsy will be conducted during the act of living donor nephrectomy and transplantation. In the case of renal mass nephrectomies, representative "normal" tissue will be obtained from the nephrectomized kidney at a site distant from the renal mass.
Renal Disease SubjectsPatients who require a renal biopsy based upon clinical indications such as proteinuria, hematuria, acute renal failure (ARF) of unclear etiology, chronic kidney disease of unclear etiology, nephrotic syndrome, nephritic syndrome, suspected lupus nephritis or any other medically warranted indication for a biopsy.

What is being measured

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

  1. The deviation from the norm of whole blood, serum and urine inflammatory and immune mediators, renal biopsy gene signature patterns in subjects with a variety of biopsy proven renal conditions compared to normal subjects.

    To determine the deviation from the norm of blood and urine inflammatory and immune mediators in subjects that have undergone renal biopsy for clinical indication with resultant biopsy diagnosed renal conditions.

    To determine the correlation of serum, whole blood and urine inflammatory and immune mediators with the renal pathologic diagnosis as well as the gene signature of the given pathology.

    Measured: 12 months

Secondary outcomes (1)
  1. Change over time of serum, whole blood and urine inflammatory and immune mediators.

    Subjects clinical course and outcome will be followed over five years and related to change over time of serum, whole blood and urine inflammatory and immune mediators. This follow-up analysis may yield markers that correlate with therapeutic response.

    Measured: 5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Proteinuria and Kidney Injury, run by The Rogosin Institute 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 4 inclusion and 3 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 15 Mar 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 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?

The deviation from the norm of whole blood, serum and urine inflammatory and immune mediators, renal biopsy gene signature patterns in subjects with a variety of biopsy proven renal conditions compared to normal subjects. (time frame: 12 months). 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 15 Mar 2024; AzTrials last refreshed its copy on 7 Nov 2026.
