About this study
Official title: Effect of Canagliflozin on Ultrafiltration and Fibrosis in Peritoneal Dialysis: a a Proof-of-concept Randomized Phase II Crossover Clinical Trial
This is a phase II, proof-of-concept, placebo-controlled, double-blind, cross-over randomized clinical trial, assessing the effect of canagliflozin on peritoneal membrane function in patients on PD.
The primary aim of this trial is to determine the short-term effects of canagliflozin, an SGLT-2 inhibitor, on glucose absorption by the peritoneal membrane and on ultrafiltration, as assessed by a standardized peritoneal equilibrium test. The secondary aims are to determine the effect of canagliflozin on solute clearance and on effluent biomarkers of inflammation, angiogenesis, and fibrosis at 26 weeks. We hypothesize that canagliflozin will prevent glucose absorption by the peritoneal membrane, as compared with placebo, and will attenuate the development of inflammation, angiogenesis, and fibrosis of the peritoneal membrane, as assessed by relevant biomarkers in the dialysate.
Read the detailed description
Patients with kidney failure on peritoneal dialysis who meet the study inclusion criteria will be randomized at a 2:2:1 ratio to one of the following arms:
(i) canagliflozin 300 mg once daily for 5 weeks (double-blind), followed by matching placebo once daily for 5 weeks (double-blind), followed by canagliflozin 300 mg once daily for 16 weeks (open label).
(ii) placebo once daily for 5 weeks (double-blind), followed by canagliflozin 300 mg once daily for 5 weeks (double-blind), followed by canagliflozin 300 mg once daily for 16 weeks (open label).
(iii) standard of care, with no active treatment, for 26 weeks (open label). Four in-person and one phone study visits have been scheduled: baseline visit, week 5, week 10, week 18 (phone visit), and week 26. A standardized peritoneal equilibration test (PET) will be performed at each of the in-person visits. There will also be two safety assessments at weeks 2 and 7, which will consist of blood tests. Patients who develop intercurrent illnesses or are hospitalized may temporarily discontinue the study drug if deemed appropriate by the treating physician.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Canagliflozin 300 MG in people with ESRD and CKD (Chronic Kidney Disease) Stage 5D, run by McGill University Health Centre/Research Institute of the McGill University Health Centre at 1 site in Canada.
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 8 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: looking for participants now, as of the sponsor's last update on 16 Mar 2026. 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 Canada. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Efrosyne Tsirella (514-934-1934 ext. 37836, efrosyne.tsirella@muhc.mcgill.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change in D4/D0 (time frame: 5 and 10 weeks from baseline). 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 Mar 2026.
