About this study
Official title: Comparison of the Effects Between Keto-/Amino Acid Supplemented Low Protein Diet and Non-Supplemented Low Protein Diet in Patients With Stage Ⅴ Chronic Kidney Disease
Keto-/amino acid supplemented low protein diet can reduce uremic symptoms, improve nutritional status, delay dialysis therapy and enhance health-related quality of life in our patients with stage V CKD in comparison to non-supplemented low protein diet.
Read the detailed description
Fifty patients will be included into the study. The study comprises 9 visits. The treatment period covers 6 months, preceded by a 2-week screening period and a 1 month run-in period. Patients are required to visit the investigator two times before the start of active treatment.
All patients who are qualified for this study will then be randomised by receiving their medication/introduction of dietary management using the standard simple randomization method.Group I patients will receive keto-/amino acid (Ketosteril) supplemented low protein diet during the active treatment period while Group II patients will receive non-supplemented low protein diet during the same period. The daily dose of keto-/amino acid for each Group I patient is one tablet every 5 kg body weight. The total daily dose will be divided into three times a day.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing ketoaminoacid in people with Chronic Kidney Disease, run by National Taiwan University Hospital.
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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 16 Aug 2006. Status can change between updates, so confirm with the study contact before making plans.
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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Kao Tze-Wah, MD, Master (886-2-23123456 ext. 2919, twkao@ha.mc.ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Glomerular filtration rate (GFR) and creatinine clearance (Ccr). 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 16 Aug 2006.
