About this study
Official title: Characterisation of Patient Profile and Contemporary Treatment of Pre-dialytic Chronic Kidney Disease (CKD) in Patients Receiving a Restricted Protein Diet Supplemented With Ketosteril® - a Drug Utilisation Study (DUS)
The purpose of this study is to characterise the patient and disease profile under the influence of a protein-restricted diet supplemented with keto acids/amino acids (KA/AA), focusing on the progression of chronic renal insufficiency, calcium and phosphorus metabolism, nutritional status, patient compliance to diet and Ketosteril intake as well as the persistent dietary education to ensure compliance in a large group of pre-dialysis patients.

What is being measured
The primary outcome is the main question the study is designed to answer.
Patient compliance to Ketosteril (number of tablets taken; patient-reported)
This is an observational study aiming to characterise the patient profile and contemporary treatment of pre-dialytic chronic kidney disease (CKD) in patients receiving a restricted protein diet supplemented with Ketosteril® . There is no distinction between primary and secondary outcome measures in the observational plan, and only routine procedures are documented.
Measured: Daily, for a total of 12 months

Questions about this trial
What is this clinical trial studying?
An observational study of Chronic Kidney Disease, run by Fresenius Kabi at 1 site in Hungary.
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 17 Oct 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 Hungary. 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.
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?
Patient compliance to Ketosteril (number of tablets taken; patient-reported) (time frame: Daily, for a total of 12 months). 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 17 Oct 2018.
