Efficacy and Mechanisms of Dapagliflozin in Promoting Kidney Function and Cardiovascular Health in Kidney Transplant Recipients
A Phase 4 study testing Dapagliflozin 10mg Tab in people with Kidney Transplant; Complications and Vascular Diseases, run by University of Colorado, Denver at 1 site in United States.
Trial summary
Long-term allograft function in kidney transplant recipients (KTRs) remain suboptimal, and graft failure causes significant morbidity and mortality, with cardiovascular disease being the leading cause of death in KTRs and the most common cause of death with a functioning graft.

About this study
Long-term allograft function in kidney transplant recipients (KTRs) remain suboptimal, and graft failure causes significant morbidity and mortality, with cardiovascular disease being the leading cause of death in KTRs and the most common cause of death with a functioning graft. Sodium-glucose cotransporter 2 (SGLT2) inhibitors safely lower cardiovascular and kidney disease risk in the non-transplant population, yet data in KTRs are lacking. This clinical trial seeks to establish the efficacy and safety of dapagliflozin, a SGLT2 inhibitor, for improving cardiovascular and kidney graft function in adult KTRs with type 2 diabetes and post-transplant diabetes, and to leverage innovate translational methods to define the underlying mechanisms of action.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Dapagliflozin 10mg Tab in people with Kidney Transplant; Complications and Vascular Diseases, run by University of Colorado, Denver at 1 site in United States.
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 12 inclusion and 13 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 May 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 United States. 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 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 Jessica Kendrick (3037244837, Jessica.Kendrick@cuanschutz.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Albuminuria (time frame: Change from baseline to 12 months). 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 29 May 2025; AzTrials last refreshed its copy on 8 Nov 2026.
