Analysis of Calcium Balance in Chronic Kidney Disease
NCT00974532 · View on ClinicalTrials.gov ↗
Study Summary
Subjects with normal kidney function are able to excrete in their urine the calcium and phosphorus absorbed via the gastrointestinal tract and are thereby are able to maintain calcium and phosphorus balance. Patients with chronic kidney disease often have normal blood levels of calcium and phosphorus but no research has been conducted to determine if they are able to excrete their daily intake of these minerals. If they are not able to excrete their daily intake, these minerals could be deposited in soft tissue and blood vessels and contribute to the increased risk of cardiovascular disease seen in patients with chronic kidney disease. This study will determine if subjects with chronic kidney disease are in balance primarily with regard to calcium and at what level of kidney function they are no longer able to maintain balance. Understanding whether patients with chronic kidney disease are in balance will help direct future therapeutic interventions.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00974532
The ClinicalTrials.gov registry entry for NCT00974532 describes a study currently listed as completed. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 16 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Colorado, Denver, which has 1,447 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Chronic Kidney Disease appearing as the primary indexed condition, and to 2 interventions — of which High calcium diet 2000 mg/day is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00974532 reports 1 study location spanning 1 distinct geographic area — top geographies include Colorado. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
