Prospective Diabetes Registry of Patients With Type 2 Diabetes Mellitus on SGLT 2 Inhibitor Therapy in Singapore

Study Overview
=================
Brief Summary
-----------------
To evaluate clinical effectiveness and safety of Singaporean Type 2 Diabetes mellitus patients administered SGLT 2 inhibitor monotherapy or in combination with other commonly used hypoglycaemic drugs in real life clinical settings. To evaluate real life clinical effectiveness and safety of Sodium-Glucose Co-Transporter inhibitor- 2 in Singaporean Type 2 diabetes mellitus patients treated on an outpatient basis in clinical practice setting. The study would also assess treatment patterns with SGLT2 inhibitor patient relevant outcomes in whole population as well as pre identified patient subgroups. Primary analysis to be done at 1 year and extended analysis at 2 years.

Detailed Description
-----------------
T2DM is associated with overweight/obesity and high fasting plasma glucose (FPG) in White patients, whereas Asian patients are more predisposed to high abdominal fat distribution and high postprandial glucose (PPG) levels, thought to contribute1-4. In response to identical meals, Asian subjects exhibit greater glycemic response than do White subjects4,5. According to the Diabetic Society of Singapore, one out of nine people aged 18 to 69 has diabetes, that's about 11.3% of the population or more than 400,000 people & this is expected to rise with the increasing prevalence of a sedentary lifestyle and high-calorie dietary intake. SGLT2 inhibitors offers a novel insulin-independent approach to lowering hyperglycaemia and improving metabolic control of type 2 diabetes: they reduce renal glucose reabsorption by inhibition of SGLT2 transporters in the proximal tubule of the kidney, resulting in urinary glucose excretion. Since SGLT2 inhibition is independent of β-cell function or insulin sensitivity, this treatment approach could have applications throughout the natural history of diabetes.6 The reductions in fasting plasma glucose concentration and bodyweight during the treatment with the SGLT2 i, are sustained. Early weight loss, is partly due to a mild osmotic diuresis caused by SGLT2 I, however, the gradual progressive reduction in bodyweight thereafter, with decreased waist circumference, is consistent with a reduction of fat mass. This reduction is potentially attributable to the loss of excess energy through glucose excretion in the urine, an effect supported by the increased urinary glucose/creatinine ratio in patients assigned to SGLT2i.6 Many trials shows that SGLT2 i can improve glycaemic control in patients who have inadequate control with metformin. The drug acts independently of insulin, lowers weight, and is not associated with risk of hypoglycaemia. Safety and tolerability of the drugs were also confirmed. Therefore, addition of SGLT2i to metformin provides a new therapeutic option for treatment of type 2 diabetes.6 Data collection will be done by AZ medical personnel or Pharmacy interns, it will be a paper data collection and will be handed over to the CRO company for data entry & analysis..Data analysis will be done by an independent CRO company namely BioQuest Solutions.
