Trial summary

Patients with end-stage renal disease (ESRD) commonly have high concentrations of phosphorous, a mineral, in the blood (hyperphosphatemia). This is a result of their inability to excrete phosphorous by the kidneys. Read more about this study

About this study

Patients with end-stage renal disease (ESRD) commonly have high concentrations of phosphorous, a mineral, in the blood (hyperphosphatemia). This is a result of their inability to excrete phosphorous by the kidneys. This in turn may result in the development of a condition known as secondary hyperparathyroidism and renal osteodystrophy or bone disease. As such, these patients often receive medications known as phosphate binders such as calcium carbonate or acetate, sevelamer, aluminum hydroxide and lanthanum carbonate to manage and treat hyperphosphatemia.

Lanthanum carbonate is a newly available phosphate binding agent that is effective in the management of hyperphosphatemia and preventing secondary hyperparathyroidism. It works in the gastrointestinal tract by binding to the phosphorus in the diet. ESRD patients taking lanthanum carbonate are counseled to chew the tablets completely before swallowing, with or immediately after meals. However, patients who are intubated or receiving nutrition via feeding tubes are unable to chew the tablets. For these patients, medications are commonly crushed and administered via the tube. Moreover, some patients prefer to crush the tablets and mix it with food instead of chewing. To date, it is not known if crushing the lanthanum carbonate tablets prior to administration and taking it with food would be as effective as chewing them.

The purpose of this study is to compare the efficacy of phosphate binding between chewed and crushed lanthanum carbonate tablets.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Lanthanum carbonate (chewed vs. crushed) in people with Hyperphosphatemia in Chronic Kidney Disease, run by University of Illinois Chicago 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 7 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 20 Dec 2019. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Serum phosphorous concentration (time frame: Hourly from time=0-8 h after administration of meal and drug). 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 20 Dec 2019.
