2) Patients with type 2 diabetes requiring medication.
3) Patients who have never been treated with medication for type 2 diabetes.
4) Patients with HbA1c less than 9.0%.
5) Patients who have the capacity to consent and have provided written informed consent.

(1) Patients with type 1 diabetes.
(2) Patients requiring insulin therapy (e.g., insulin-dependent, insulin-independent but requiring insulin therapy to correct hyperglycemia, severe ketosis, diabetic coma or pre-coma, severe infection, pre- or postoperative, severe pancreatic disease, severe trauma).
(3) Patients with a history of taking alpha glucosidase inhibitors or SGLT2 inhibitors.
(4) Patients who are pregnant or lactating or may be pregnant or wish to become pregnant during the research period.

(8) Patients treated with oral or injectable corticosteroids.
(9) Patients with eGFR <45 mL/min/1.72 m^2.
(10) Patients with severe liver disease (AST or ALT > 100 IU/L).
(11) Patients with poorly controlled dysuria due to neurogenic bladder, benign prostatic hyperplasia, etc.
(12) Patients with symptomatic urinary tract infection or genital infection.

(14) Patients with a history of renal disease, such as nephrectomy, renal transplantation, etc.
(15) Patients who underwent gastrectomy.
(16) Patients who cannot avoid eating, drinking, or taking other medications for at least 30 minutes after waking up.

Type 2 Diabetes

The subjects are randomly assigned to one of three groups and treated for 24 weeks: T) Tofogliflozin 20 mg/day, S) oral semaglutide 3, 7 or 14 mg/day and I) imeglimin 2000 mg/day. Randomization will be performed using a dynamic randomization algorithm designed to minimize imbalance in BMI and 75-g oral glucose tolerance test derived disposition index (DI) before treatment. The subjects will undergo a 75-g oral glucose tolerance test at week 25 (after a 1-week wash-out period).

Change in Disposition Index (DI: Insulinogenic Index(II)120 min * Matsuda index) at week 25 (after 1-week wash-out period) from baseline

(1) Change in the following other DIs from baseline at week 25:
1.DI2: II 30 min * Matsuda index
2.DI3: II 30 min * 1/Ins0
3.DI4: delta AUCIns0-120 / delta AUCGlu0-120 *
Matsuda index

(2) Change in II 30 min and II 120 min from baseline at week 25

(3) Percentage change in the following DIs from baseline at week 25:
1.DI: II 120 min * Matsuda index
2.DI2: II 30 min * Matsuda index
3.DI3: II 30 min * 1/Ins0
4.DI4: delta AUCIns0-120 / delta AUCGlu0-120 * Matsuda index

(4) Percentage change in II 30 min and II 120 min from baseline at week 25

(5) Change in the following parameters at week 25 from baseline:
1.HbA1C
2.Fasting glucose
3.HOMA-Beta*
*HOMA-beta = (0-min insulin levels*360) / (0-min glucose levels-63)
4. BMI, blood pressure, pulse rate, Hb, TG, LDL-C, HDL-C, UN, Cr, UA, GFR, Na, K, Cl, AST, ALT, gamma-GTP, ALP
