Effects of a Non-Calcium Based Phosphate Binder on FGF23 Levels in Chronic Kidney Disease
A Early Phase 1 study testing Sevelamer Carbonate in people with Chronic Kidney Disease, run by Milton S. Hershey Medical Center at 1 site in United States.
Trial summary
Fibroblast Growth Factor 23 (FGF23) is a molecule that has been implicated in the homeostasis of phosphorus. Elevated FGF23 levels are well-documented in patients with Chronic Kidney Disease (CKD) and are inversely correlated with Glomerular Filtration Rate (GFR). Read more about this study

About this study
Fibroblast Growth Factor 23 (FGF23) is a molecule that has been implicated in the homeostasis of phosphorus. Elevated FGF23 levels are well-documented in patients with Chronic Kidney Disease (CKD) and are inversely correlated with Glomerular Filtration Rate (GFR). FGF23 levels are also predictive of progression of CKD and predict mortality in CKD. Although studies in normal individuals suggest that phosphorus intake is related to FGF23 levels, the effect of dietary and pharmacologic phosphate restriction on FGF23 levels in patients with CKD has never been reported. Our objectives are to determine if phosphate reduction through the use of non-calcium based phosphate binder will decrease serum FGF23 levels. The investigators will also be investigating associations of elevation in FGF 23 levels with commonly encountered co-morbidities in CKD patients such as Coronary Artery Disease, Diabetes Mellitus, and Hypertension.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Fibroblast Growth Factor 23 (FGF23) is a molecule that has been implicated in the homeostasis of phosphorus. Elevated FGF23 levels are well-documented in patients with Chronic Kidney Disease (CKD) and are inversely correlated with Glomerular Filtration Rate (GFR). FGF23 levels are also predictive of progression of CKD and predict mortality in CKD. Although studies in normal individuals suggest that phosphorus intake is related to FGF23 levels, the effect of dietary and pharmacologic phosphate restriction on FGF23 levels in patients with CKD has never been reported.

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Sevelamer Carbonate in people with Chronic Kidney Disease, run by Milton S. Hershey Medical Center 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 1 inclusion and 1 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 2 May 2018. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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?
Effects of a Non-Calcium Based Phosphate Binder on FGF23 Levels in Chronic Kidney Disease (time frame: March 2011-June 2012). 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 2 May 2018.
