Study summary

The goal of this clinical trial is to test if SGLT2 inhibitors could prevent or delay the development of Cardiac Allograft Vasculopathy (CAV) post-heart transplantation (TxC). The main questions it aims to answer are:

Primary outcome: CAV, according to ISHLT grading system diagnosed by CCTA; Secondary outcomes: cardiovascular death, all-cause mortality, hospitalization, worsening glomerular filtration rate, fasting glucose, weight, and blood pressure.

Exploratory and safety outcomes: Rejection, hypoglycemia, urinary tract infection, hypovolemia, and limb amputation.

HYPOTHESIS The null hypothesis is that SGLT2 inhibitors do not reduce the incidence of CAV in transplanted patients.

The alternative hypothesis is that SGLT2 inhibitors reduce the incidence of CAV in transplanted patients.METHODOLOGY Study Design A randomized clinical trial of superiority with active control (2 arms), with central randomization and blinded evaluation of outcomes, to evaluate the efficacy and safety of adding dapagliflozin or empagliflozin 10 mg once daily to conventional post-TxC treatment compared with the treatment of isolated conventional post-TxC for 6-8 months.

Study Sample Sample: All adult patients undergoing a heart transplant between January 2017 and December 2023 at Hospital de Messejana.

Inclusion Criteria Included: Patients of both sexes, aged ≥ 18 years, who have undergone heart transplantation between January 2017 and December 2023 and are under the care of the Heart Transplant and Heart Failure Unit at Hospital de Messejana.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 7, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
