About this study

This is a pilot randomized, controlled trial of Vitamin D supplementation in patients on peritoneal dialysis to determine the feasibility of a future full-scale RCT exploring if oral administration of vitamin D3 could reduce the risk of subsequent Peritoneal dialysis-related (PD-related) peritonitis.

Aims of the study:

Aim 1: To determine the feasibility of oral vitamin D supplementation among PD patients who have recovered from a recent episode of peritonitis.

Aim 2: To examine the effect of vitamin D supplementation on the risk for peritonitis among patients on peritoneal dialysis.

Read the detailed description

Patients will be screened for eligibility one month after the onset of PD-related peritonitis, those who meet the inclusion criteria will be enrolled in this study.

All consenting participants will be randomized into the vitamin D treatment group or the control group, general information and baseline biochemistry data would be collected. Patients in the treatment group will be treated with oral Cholecalciferol (2000IU/day) apart from routine treatment for PD. Those in the control group will receive routine treatment for PD. Both groups will be followed for 12 months. During the observational period, any onset of subsequent peritonitis will be recorded, serum 25(OH)D, biochemical indices will be measured every 3 months. Follow up would take place frequently, any outcome events would be recorded.

Aims and hypotheses:

Aim 1: To determine the feasibility of oral vitamin D supplementation among PD patients who have recovered from a recent episode of peritonitis.

Hypothesis1: A large、full-scale randomized controlled trail on the effects of oral vitamin D on the risk for peritonitis among PD patients is feasible.

Aim 2: To examine the effect of vitamin D supplementation on the risk for peritonitis among patients on peritoneal dialysis.

Hypothesis 2: Oral supplementation of vitamin D will reduce the risk of subsequent peritoneal dialysis.

  2. Probability of participants who recovered after subsequent peritoneal dialysis related peritonitis.

    Probability of participants who recovered after peritoneal dialysis-related peritonitis measured by percentage.

    Measured: From date of randomization until the date of documented death, assessed up to 1 year.

  3. Risk of participants who died because of subsequent peritoneal dialysis related peritonitis.

    Risk of participants who died because of peritoneal dialysis-related peritonitis measured by percentage.

    Measured: From date of randomization until the date of documented death, assessed up to 1 year.

  4. Risk of participants who are transitioned to hemodialysis because of subsequent peritoneal dialysis related peritonitis.

    Risk of patients who are transferred to hemodialysis because of peritoneal dialysis related peritonitis measured by percentage.

    Measured: From date of randomization until the date of documented transition to hemodialysis because of peritoneal dialysis related peritonitis, assessed up to 1 year.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Cholecalciferol (2000iu qd) and Routine therapy for PD in people with Peritoneal Dialysis-associated Peritonitis and Vitamin D Deficiency, run by Peking University First Hospital at 1 site in China.

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 4 inclusion and 5 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 Aug 2021. 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 China. 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. Some participants in this study may receive a placebo. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

Recruitment rate of the trial (time frame: From date of randomization until 1 year after the randomization of last participant.). The study lists 5 primary outcomes in all. 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 NCT03264625, which also lists 3 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 18 Aug 2021.
