What is the purpose of this trial?

This trial tests dapagliflozin to determine its effects on heart and kidney health in individuals with a kidney transplant who also have type 2 diabetes or diabetes post-transplant. The trial compares dapagliflozin to a placebo (a pill with no active medicine) to assess its effectiveness. It seeks participants who had a kidney transplant at least a year ago, have stable diabetes and blood pressure, and regularly take certain medications. As a Phase 4 trial, this research aims to understand how the already FDA-approved and effective dapagliflozin can benefit more patients.

Will I have to stop taking my current medications?

The trial requires that your current medications for immunosuppression, blood pressure, diabetes, and certain other conditions remain stable for at least 1-3 months before starting. If you're currently using SGLT2 inhibitors, you cannot participate.

What is the safety track record for dapagliflozin?

Studies have shown that dapagliflozin, the treatment being tested in this trial, is generally safe for people with chronic kidney disease. In earlier research, only about 2% of patients stopped using the drug due to side effects. The most common issues included sudden kidney problems and urinary tract infections. Importantly, dapagliflozin is already approved for other conditions, such as heart failure and chronic kidney disease, indicating it is well-tolerated by many people. Although limited information exists for kidney transplant recipients, these findings are promising for its safety. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Dapagliflozin is unique because it targets kidney complications by inhibiting the sodium-glucose co-transporter 2 (SGLT2), a mechanism different from the usual blood pressure control or glucose management seen in traditional treatments like ACE inhibitors or ARBs. Researchers are excited about dapagliflozin because it not only helps manage blood sugar levels in people with diabetes but also offers protective benefits for the kidneys, potentially slowing down the progression of kidney disease. This dual action makes dapagliflozin a promising option for enhancing kidney health beyond the capabilities of current standard treatments.

What evidence suggests that dapagliflozin might be an effective treatment for kidney complications in kidney transplant recipients?

Research has shown that dapagliflozin, which participants in this trial may receive, can help slow chronic kidney disease. Studies have found that it can delay kidney failure by several years. Dapagliflozin also reduces the risk of serious kidney and heart problems, including death from heart-related issues. It works effectively regardless of the initial condition of the kidneys. This treatment is already approved for managing chronic kidney disease, demonstrating its effectiveness in improving kidney and heart health. ^{1 2 4 6 7}

Are You a Good Fit for This Trial?

This trial is for adult kidney transplant recipients aged 18-80 with stable blood pressure, diabetes management, and immunosuppression. Participants must have received their transplant at least a year ago and have specific levels of kidney function and protein in urine. It's not suitable for those who don't meet these health criteria or can't consent.

Inclusion Criteria

My kidney function, measured by eGFR, is between 30 and 90.

My urine protein levels are between 30 to 5000 mg/g.

I have type 2 diabetes or diabetes developed after a transplant.

What Are the Treatments Tested in This Trial?

Interventions

• Dapagliflozin

Trial Overview

The study tests if Dapagliflozin, a drug that lowers sugar in the body, improves heart health and kidney function in people who got a new kidney but also have diabetes. Some will get the real medicine while others will take a placebo to compare results.

How Is the Trial Designed?

Group I: Dapagliflozin Experimental Treatment 1 Intervention

Participants will receive dapagliflozin 10mg daily

Group II: Placebo Placebo Group 1 Intervention

Participants will receive one placebo tablet daily

Published Research Related to This Trial

Dapagliflozin (DAPA) is an effective SGLT2 inhibitor for treating type 2 diabetes, showing favorable pharmacokinetics and pharmacodynamics that help lower blood sugar levels while having beneficial effects on other metabolic risk factors.

While DAPA is generally safe, it carries an increased risk of genital and urinary infections, and concerns about bladder cancer and cardiovascular safety remain, prompting the FDA to seek further data on these issues.

Dapagliflozin (Farxiga) is approved for reducing the risk of declining kidney function and kidney failure in adults with chronic kidney disease, regardless of whether they have type 2 diabetes.

It also helps lower the risk of cardiovascular death and hospitalization for heart failure, highlighting its efficacy in managing both kidney and heart health.

Antidiabetic Drug Approved to Reduce Risk of Kidney Disease. Aschenbrenner, DS.[2023]

Dapagliflozin has been shown to significantly improve kidney outcomes in patients with chronic kidney disease, demonstrating its efficacy in reducing the risk of kidney disease progression.

The study involved a large cohort of patients, providing robust evidence for the safety and effectiveness of dapagliflozin in managing chronic kidney disease.

In CKD, dapagliflozin reduced a composite of eGFR decline, end-stage kidney disease, or CV or renal mortality. Molony, DA., LeMaistre, FI.[2021]

Dapagliflozin effectively lowers blood sugar levels and glycated hemoglobin (HbA1c) in patients with type 2 diabetes, with a low risk of hypoglycemia and additional benefits like weight loss and reduced blood pressure.

While it is generally safe, dapagliflozin can increase the risk of genital infections, particularly in women, and its efficacy may be reduced in patients with kidney issues; ongoing trials are investigating its potential cardiovascular and renal protective effects.
