What this trial studies

This multicenter, open-label study involves 46 drug-naïve adults with type 2 diabetes (T2D) who are randomized to receive either empagliflozin (10 mg/day) or metformin (1,000 mg/day) for a duration of 12 weeks. Participants must have an HbA1c level between 6.5% and 10.0% and be aged between 20 and 75 years. The study aims to evaluate the effectiveness of these medications in managing glucose variability in T2D patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 20 to 75 with drug-naïve type 2 diabetes and an HbA1c between 6.5% and 10.0%.

Not a fit: Patients with significant comorbidities such as severe obesity, uncontrolled hypertension, or recent cardiovascular events may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights into more effective treatment options for managing type 2 diabetes.

How similar studies have performed: Other studies have shown success with similar approaches in managing type 2 diabetes, indicating potential for positive outcomes.

Inclusion Criteria:

* Participants were eligible if they had T2D with an HbA1c between 6.5% and 10.0%, were between 20 and 75 years of age, and had not received any anti-diabetic medications for at least eight weeks prior to screening.

Exclusion Criteria:

* individuals with a body mass index (BMI) \<18.5 kg/m² or ≥40 kg/m², clinically significant hepatic impairment (e.g., hepatic cirrhosis, portal hypertension, chronic active hepatitis), or a history of acute cardiovascular events (e.g., coronary artery disease, cerebrovascular disease, peripheral arterial disease) within two months prior to enrollment. Participants with CKD (eGFR \<60 mL/min/1.73 m²) or end-stage renal disease (eGFR \<15 mL/min/1.73 m² or on dialysis) were also excluded.
