Effect of Tofogliflozin on Urine Albumin-to-Creatinine Ratio Compared to Metformin Hydrochloride in Diabetic Kidney Disease
This multicenter, randomized, open-label, controlled study will assess the efficacy of the SGLT2 inhibitor tofogliflozin on Urine Albumin-to-Creatinine Ratio (UACR) compared to metformin in patients with type 2 diabetes with chronic kidney disease (CKD).
• Type 2 diabetic patients
• Patients aged 20 years or older at the time of obtaining consent
• Patients with HbA1c 6.5 or more and 9.0% or less within 13 weeks before obtaining consent (evaluated by test values after 4 weeks or more without taking SGLT2 inhibitor / metformin)
• Patients who have been judged by their doctor to need a diabetic drug when they are first seen, or who have already taken a diabetic drug and have decided that it is necessary to add one diabetic drug.
• Patients who have been receiving RAS inhibitors (ARB, ARNI, ACE inhibitors, direct renin inhibitors) for 4 weeks or longer
• Patients with eGFR of 30 or more (mL / min / 1.73m2) within 13 weeks before obtaining consent (evaluated by test values after 4 weeks or more without taking SGLT2 inhibitor / metformin)
• Patients with urinary albumin / creatinine ratio (UACR) of 30 or more and less than 2000 (mg / gCr) (4 weeks or more without taking SGLT2 inhibitor / metformin) within 13 weeks before obtaining consent Evaluate by inspection value)
• Patients for whom written consent was obtained based on the patient's free will after receiving sufficient explanation for participation in this study
