What is being measured

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

  1. Demonstrate the equivalence of sevelamer carbonate powder to sevelamer hydrochloride tablets dosed three times per day (TID) with meals on the control of serum phosphorus levels

    Measured: Up to 13 weeks

  2. Evaluate the safety and tolerability of sevelamer carbonate powder compared to sevelamer hydrochloride tablets dosed TID with meals

    Measured: Up to 13 weeks

Secondary outcomes (2)
  1. Compare the effects of sevelamer carbonate powder to sevelamer hydrochloride tablets when dosed three times a day with meals on: serum calcium-phosphorus product

    Measured: Up to 13 weeks

  2. serum lipid profile (total cholesterol, high density lipoprotein [HDL] and low density lipoprotein [LDL] and triglycerides)

    Measured: Up to 13 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing sevelamer carbonate (Renvela®) sevelamer hydrochloride (Renagel ®) and sevelamer hydrochloride (Renagel ®) sevelamer carbonate (Renvela®) in people with Chronic Kidney Disease, run by Genzyme, a Sanofi Company at 7 sites in United Kingdom.

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 17 inclusion and 10 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 18 Mar 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 sites in United Kingdom. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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?

Demonstrate the equivalence of sevelamer carbonate powder to sevelamer hydrochloride tablets dosed three times per day (TID) with meals on the control of serum phosphorus levels (time frame: Up to 13 weeks). The study lists 2 primary outcomes in all. 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 18 Mar 2015.
