About this study

Official title: Effects of Creatine Supplementation in Sarcopenic and Non-sarcopenic Patients on Chronic Hemodialysis

Adult patients undergoing chronic dialysis therapy for at least three months were selected. A physical function assessment was conducted, including the Short Physical Performance Battery (SPPB) and a handgrip strength test. Additionally, a bioelectrical impedance analysis was performed. Subsequently, 5 grams of creatine were administered daily for a period of eight weeks, after which the same assessments were repeated. The results were then analyzed to identify any differences in the tests, aiming to detect potential changes following creatine supplementation.

Read the detailed description

Adult patients undergoing chronic dialysis therapy for at least three months were selected, primarily based on their good adherence to pharmacological and dialysis treatment regimens. A physical function assessment was conducted, including the Short Physical Performance Battery (SPPB) and a handgrip strength test. Additionally, a bioelectrical impedance analysis was performed.

All participants were informed that creatine would be administered and provided written informed consent. The study protocol was approved by the local ethics committee.

Creatine supplementation consisted of 5 grams per day for eight weeks. On dialysis days, the dose was administered immediately after the dialysis session. On non-dialysis days, patients were responsible for self-administering the creatine at home. The creatine was diluted in 100 mL of water before ingestion.

All assessments were conducted the day following the second dialysis session of the week-on Thursday or Friday, depending on the patient's schedule. There was no control group so pre-creatine measurements were considered as the basal (control) state. Measurements were taken before and after the creatine supplementation period in the same patients. The data were analyzed to evaluate changes in the outcomes following creatine use.

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 3 inclusion and 2 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 24 Jun 2025. 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 Chile. 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?

Compare Short Physical Performance Battery (SPPB) before and after 8 weeks of creatine use (time frame: eigth weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07033611, which also lists 27 linked publications.

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 24 Jun 2025.
