Inclusion criteria

Inclusion criteria: diagnostic criteria—defined as random plasma glucose >11.1 mmol/L, fasting plasma glucose >7.0 mmol/L, or HbA1c =6.5%—are eligible for participation. Eligible participants must be receiving metformin monotherapy at a stable dose (=1000 mg/day) for at least eight weeks prior to enrollment and must demonstrate willingness to begin dapagliflozin therapy as part of the trial. All participants must provide written informed consent and demonstrate adequate compliance during the single-blind placebo run-in period (=70% based on pill count) before randomization

Exclusion criteria

Exclusion criteria: patients will be excluded if they have type 1 diabetes mellitus, HbA1c =7%, or if they are currently using any antidiabetic therapy other than metformin. Additional exclusion criteria include congestive heart failure (NYHA class III or IV) , significant gastrointestinal disorders, chronic or recurrent urinary tract infections, liver cirrhosis, uncontrolled hypertension (>170/110 mmHg), use of systemic corticosteroids =10 mg prednisolone daily, end-stage renal disease requiring dialysis, or any condition that affects HbA1c accuracy (e.g., hemoglobinopathies, uremia, advanced liver disease). Pregnant or breastfeeding women, individuals with known hypersensitivity to dapagliflozin or metformin, those with alcohol abuse, poor compliance risk, inability to understand study procedures, or any condition that the investigator determines unsafe for participation are also excluded.
