About this study
Official title: Obesity Management for Kidney TRANSPLANTation: a Vanguard Study for an Innovative Randomized Controlled Trial, Embedded in Routine Care (OK-TRANSPLANT 2)
OK-TRANSPLANT 2 is a vanguard study for a large randomized, pragmatic, open-label trial.
We will randomize participants with obesity, high-risk CKD/dialysis who are hoping for lose weight for the purpose of kidney transplant. Subjects will either be enrolled on a virtual weight management program or continue their usual care.
Read the detailed description
Obesity is well-recognized as an independent risk factor for chronic kidney disease (CKD) including end-staged kidney disease (ESKD). In people with ESKD, obesity can preclude access to lifesaving kidney transplantation. Of solid organ transplant programs in Canada, 80% exclude people with obesity (based upon body mass index or BMI), due to a potential risk of perioperative complications and post-transplant mortality.
Losing weight for kidney transplantation can, however, be extremely difficult. Medications that can promote weight loss in other populations including glucagon-like peptide 1 receptor agonists (GLP-1RA; liraglutide, semaglutide, and dulaglutide) and glucose-dependent insulinotropic polypeptide (GIP-1RA)/GLP-1RAs (tirzepatide), have not been studied in devoted trials of advanced CKD participants, and their efficacy and safety remain unclear.
Nutritional advice is often very difficult to follow when trying to balance kidney and diabetes diets (e.g. potassium), and if diets are too restrictive, there may be protein-energy wasting which could be detrimental to patients. People with high-risk CKD frequently live with functional impairment which can limit exercise. Weight loss programs can be cost prohibitive to those who are already socioeconomically disadvantaged.
A vanguard is needed before a large, multicentered RCT: A feasibility study will allow us to ensure that we can recruit a sufficient sample of participants into our trial, that our trial processes are inclusive, and that they are acceptable to patients. In the vanguard phase of our trial, we will answer the following questions:
- Is participant recruitment into a large multi-centered trial feasible?
- Will participants remain adherent to their assigned treatment arm over 26 weeks of study?
- Will participants find our program acceptable?
- Will safety events preclude us from testing our intervention in a larger RCT?

| Study group | Role | What they receive |
|---|---|---|
| Virtual Weight Management Program | Experimental | A maximum tolerated dose of semaglutide (Ozempic/Wegovy) will be administered once weekly subcutaneously, up to a dose of 2.0 mg. Participants will also receive nutritional and movement advice, as well as virtual coaching once every 4 weeks for 6 months.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Semaglutide and Virtual Weight Management Coaching in people with Obesity and Chronic Kidney Disease, run by Western University, Canada 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 3 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: looking for participants now, as of the sponsor's last update on 29 Jun 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. 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?
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 Heather LaPier, BSc (519-646-6100 ext. 65373, heather.lapier@sjhc.london.on.ca), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Feasibility of Recruitment (time frame: 12 months). 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 NCT06396416, which also lists 1 linked publication.
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 29 Jun 2026.
