What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to treat newly diagnosed Type 2 Diabetes patients with dapagliflozin or metformin. Dapagliflozin helps reduce kidney pressure and size by removing sugar through urine, while metformin controls blood sugar levels. The goal is to see if dapagliflozin can better protect the kidneys compared to metformin. Dapagliflozin was initially developed for type 2 diabetes and has shown benefits in reducing heart and kidney problems.

Will I have to stop taking my current medications?

The trial requires that participants do not take medications that interfere with the renin-angiotensin system or renal function, including diuretics, steroids, beta blockers, alpha blockers, and antiobesity drugs. If you are taking any of these, you may need to stop them to participate.

Is dapagliflozin generally safe for humans?

Dapagliflozin, also known as Farxiga or Forxiga, is generally well tolerated in humans. It has a low risk of causing low blood sugar (hypoglycemia) and is not recommended for people with moderate or severe kidney problems. The most common side effects are genital infections, especially in women. ^{1 2 3 4 5}

How does the drug dapagliflozin differ from other treatments for type 2 diabetes?

Dapagliflozin is unique because it works by blocking a protein in the kidneys that reabsorbs sugar back into the blood, leading to more sugar being excreted in urine. This mechanism is independent of insulin, making it a complementary option to other diabetes medications and it also offers benefits like weight loss and reduced blood pressure. ^{1 2 3 4 5}

What data supports the effectiveness of the drug Dapagliflozin for treating type 2 diabetes and other conditions?

Dapagliflozin is effective in lowering blood sugar levels in people with type 2 diabetes by helping the body remove excess sugar through urine. It also reduces the risk of kidney problems and heart-related issues in people with chronic kidney disease, whether or not they have diabetes. ^{1 2 3 4 5}

What Are the Treatments Tested in This Trial?

Interventions

• Dapagliflozin
• Glipizide 5 MG
• Metformin

How Is the Trial Designed?

Group I: Dapagliflozin/Normofiltration Experimental Treatment 1 Intervention

Subjects with eGFR below 124 ml/min per 1.73 m2 will be randomized to dapagliflozin, 5 mg/day. After 2 weeks (Visit 5), dapagliflozin will be increased to 10 mg/day, Subjects who are taking Metformin at time of randomization will have add Dapagliflozin added to current metformin.

Group II: Dapagliflozin/Hyperfiltration Experimental Treatment 1 Intervention

Subjects with eGFR above 125 ml/min per 1.73 m2 will be randomized to dapagliflozin, 5 mg/day. After 2 weeks (Visit 5), dapagliflozin will be increased to 10 mg/day, Subjects who are taking Metformin at time of randomization will have Dapagliflozin added to current metformin.

Group III: Metformin/Hyperfiltration Active Control 2 Interventions

Subjects who Drug naïve we will give Metformin- XR, 1000 mg/day. After 2 weeks (Visit 5), metformin will be increased to 1000 mg bid (twice a day).Subject who are on metformin at time of randomization we will add Glipizide 5 mg( to be increased to 10 mg at Visit 5), Subject who are on Glipizide at time of randomization will have Metformin- XR, 1000 mg/day added. After 2 weeks (Visit 5), metformin will be increased to 1000 mg bid (twice a day).

Group IV: Metformin/Normofiltration Active Control 2 Interventions

Subjects with eGFR below 124 ml/min per 1.73m2 drug naïve will receive Metformin- XR, 1000 mg/day. After 2 weeks (Visit 5), metformin will be increased to 1000 mg bid (twice a day).Subject who are on metformin at time of randomization we will add Glipizide 5 mg( to be increased to 10 mg at Visit 5), Subject who are on Glipizide at time of randomization we will add Metformin- XR, 1000 mg/day. After 2 weeks (Visit 5), metformin will be increased to 1000 mg bid (twice a day).

Published Research Related to This Trial

Dapagliflozin is an effective treatment for type 2 diabetes, proven through multiple controlled clinical trials that assess its efficacy, safety, and tolerability.

It is approved by the FDA for use as a standalone therapy or in combination with other glucose-lowering medications, including insulin.

Dapagliflozin: A Sodium Glucose Cotransporter 2 Inhibitor for the Treatment of Diabetes Mellitus. Davis, PN., Ndefo, UA., Oliver, A.[2021]

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 (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.

Pharmacokinetics, pharmacodynamics and clinical efficacy of dapagliflozin for the treatment of type 2 diabetes. Maranghi, M., Carnovale, A., Durante, C., et al.[2021]

Dapagliflozin is an effective SGLT2 inhibitor for managing type 2 diabetes, showing consistent reductions in blood glucose levels and body weight over long-term follow-up periods of 1-4 years across various clinical trials.

It has a low risk of causing hypoglycemia and is generally well tolerated, although it can lead to genital infections, particularly in women, and is not recommended for patients with moderate to severe renal impairment.

Dapagliflozin: a review of its use in patients with type 2 diabetes. Plosker, GL.[2022]

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.
