What You Need to Know Before You Apply

What is the purpose of this trial?

This trial examines how dapagliflozin (also known as Farxiga or Forxiga) can aid people with Type 2 Diabetes by improving blood vessel health, potentially reducing the risk of heart attacks or strokes. Researchers aim to determine if dapagliflozin enhances blood vessel function and beneficially alters certain cell types. Participants will either take dapagliflozin first and then a placebo (a pill with no medicine), or the reverse, with a short break in between. This trial suits individuals who have had Type 2 Diabetes for at least three months, have a body mass index over 25, and are not currently on certain diabetes medications. As a Phase 4 trial, this research seeks 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 you stop taking any SGLT-2 inhibitors and anticoagulation medications. If you are on these medications, you would need to discontinue them to participate.

What is the safety track record for dapagliflozin?

Research has shown that dapagliflozin, a treatment for type 2 diabetes, is generally safe. In a study with nearly 600 patients, dapagliflozin proved effective and safe, with many patients experiencing improved health. Another study found that dapagliflozin was as safe for children as for adults, indicating it is well-tolerated across age groups.

Additionally, research found that dapagliflozin did not increase the risk of major heart problems, such as heart attacks or strokes, compared to a placebo. It even helped lower the risk of death from heart-related issues. Overall, these studies suggest that dapagliflozin is a safe choice for people with type 2 diabetes. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Dapagliflozin is unique because it works by inhibiting a protein called SGLT2, which plays a key role in glucose reabsorption in the kidneys. Unlike many standard treatments for Type 2 diabetes that increase insulin levels or affect insulin sensitivity, dapagliflozin helps the body eliminate excess glucose through urine. This mechanism not only lowers blood sugar levels but may also offer benefits like weight loss and reduced blood pressure. Researchers are excited about dapagliflozin because it provides an alternative approach to managing Type 2 diabetes, expanding treatment options for patients who may not respond well to existing therapies.

What is the effectiveness track record for dapagliflozin in improving vascular health in patients with Type 2 Diabetes?

Research has shown that dapagliflozin helps manage Type 2 Diabetes. One study found it lowered the systolic blood pressure by about 2.4 points compared to a placebo. This is important because high blood pressure can lead to heart problems. In this trial, participants will receive dapagliflozin in one arm and a placebo in another, with a washout period in between. Dapagliflozin has also been shown to reduce the risk of death from heart issues or hospitalization for heart failure. This means it can help protect the heart and blood vessels in people with Type 2 Diabetes. ^{3 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Dapagliflozin

Trial Overview The study tests the effects of Dapagliflozin, an SGLT2 inhibitor drug that might improve heart and blood vessel health in T2DM patients. It will be compared to a placebo to see if it changes vascular health markers like arterial stiffness and endothelial cell function.

How Is the Trial Designed?

Group I: Dapagliflozin then Placebo Experimental Treatment 2 Interventions

Participants in this arm will receive dapagliflozin and then placebo with a 2 week wash out period in between.

Group II: Placebo then dapagliflozin Placebo Group 2 Interventions

Participants in this arm will receive placebo and then dapagliflozin with a 2 week wash out period in between.

Published Research Related to This Trial

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 (Forxiga) is no longer authorized for the treatment of type 1 diabetes mellitus, indicating a significant change in its regulatory status.

This decision reflects safety concerns or efficacy issues that may have arisen from clinical evaluations or post-marketing surveillance, emphasizing the importance of ongoing drug safety assessments.

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 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.
