Non-interventional Study to Evaluate the Ease of Reaching Individual Goals in Serum Phosphorus (Steering) (Steering)

March 5, 2015 updated by: Fresenius Medical Care Deutschland GmbH
The objective of this non-interventional study is to confirm that with standard OsvaRen® treatment it is possible to achieve in at least 60% of the patients the levels of phosphorus, total calcium, and iPTH seen in the CALMAG study also in the normal clinical practice.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Detailed Description

Only a small fraction of haemodialysis patients meet the published NKF-KDOQI standards for calcium, phosphorus, calcium x phosphorus product and intact parathyroid hormone. One of the reasons is the still difficult and insufficient therapy with phosphate binders. Even though calcium containing phosphate binders have been proven to be effective, they are reported to lead in certain patients to hypercalcaemia. This observational study therefore not only evaluates the efficacy of the phosphate binder OsvaRen® (containing calcium acetate and magnesium carbonate) but also the frequency of untoward events in daily practice as well as to the state of hyper-/ hypoparathyroidism as represented by serum iPTH values and the practice patterns used to adjust to and to fully exploit the qualities of the different available phosphate binders. In addition, the compensatory actions of the physicians, such as adaptation of the dialysate calcium or the combination with non-calcium containing phosphate binders, are going to be monitored. In order to receive additional safety data in the context of daily practice, the frequency of untoward events related to the treatment will be documented and analysed.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Time Frame
Serum phosphorus
Time Frame: 12 months

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
