Trial summary

End-stage chronic kidney disease is associated with the condition of chronic inflammation. Patients on hemodialysis are known to be predisposed to several factors that predispose to inflammation: dialysis membranes, central venous catheters, oxidative stress, fluid overload, sodium overload, uraemic toxins.

About this study

Official title: Effects of Green Propolis Extract (EPP-AF) on Inflammation in Hemodialysis Patients: a Randomized Cross-over Trial.

End-stage chronic kidney disease is associated with the condition of chronic inflammation. Patients on hemodialysis are known to be predisposed to several factors that predispose to inflammation: dialysis membranes, central venous catheters, oxidative stress, fluid overload, sodium overload, uraemic toxins. Propolis, a natural resin produced by bees from plant materials, has anti-inflammatory, immunomodulatory, and anti-oxidant properties. The aim of this study was to evaluate the impact of Brazilian green propolis extract on inflammation in hemodialysis patients.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Propolis Period (Green Propolis 250mg/day)Drug

    Also called Standard treatment for their comorbidities.

    Randomized, cross-over, open-label. Patients will go through two 4 week periods with 1 week washout between them. During the intervention period will use 250mg of green Propolis per day. In the control period they will only follow standard treatment for their comorbidities.

  • Control PeriodOther

    Also called Standard treatment for their comorbidities.

    In the control period they will only follow standard treatment for their comorbidities.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in serum level of High-sensitivity C-reactive protein from baseline to end of study periods.

    Change in high sensitivity C-reactive protein from baseline to end of study periods.

    Measured: 8 weeks

Secondary outcomes (3)
  1. Change in serum level of Interleukin-1 Beta from baseline to end of study periods.

    Change in Interleukin-1 Beta from baseline to end of study periods.

    Measured: 8 weeks

  2. Changes in serum level of alanine aminotransferase, aspartate aminotransferase, amylase and creatine kinase during the study, from baseline to end of study periods.

    To evaluate the safety of propolis use in hemodialysis patients. Measurement of changes in serum level of alanine aminotransferase, aspartate aminotransferase, amylase and creatine kinase during the study.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Propolis Period (Green Propolis 250mg/day) in people with Chronic Kidney Disease Requiring Chronic Dialysis, run by University of Sao Paulo General Hospital at 1 site in Brazil.

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 2 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 18 May 2022. 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 Brazil. 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.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

Change in serum level of High-sensitivity C-reactive protein from baseline to end of study periods. (time frame: 8 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 NCT04072341, which also lists 5 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 May 2022.
