Comparing blood sugar swings with different diabetes pill combinations in type 2 diabetes

A Multicenter Study to Evaluate Efficacy and Safety

Phase 4 Interventional JW Pharmaceutical · NCT07442006

This study will test whether different combinations of empagliflozin, metformin, linagliptin, or anagliptin reduce blood sugar swings in adults with type 2 diabetes who remain uncontrolled on metformin plus an SGLT2 inhibitor.

What this trial studies

This is a multicenter, phase 4, interventional trial comparing several combination oral regimens in people with type 2 diabetes who have inadequate control on metformin and an SGLT2 inhibitor. Participants will be assigned to treatment arms that include combinations such as empagliflozin/metformin, empagliflozin/linagliptin, anagliptin, or metformin alone to observe effects on glycemic variability. Continuous glucose monitoring and routine safety labs will be used to measure day-to-day glucose fluctuations and adverse events. The trial focuses on both efficacy for reducing variability and the safety profile in a real-world treatment setting.

Who should consider this trial

Good fit: Adults with type 2 diabetes who have inadequate glycemic control despite taking metformin (≥1,000 mg/day) plus an SGLT2 inhibitor, and who do not have significant renal, hepatic, or advanced heart failure, are ideal candidates.

Not a fit: People with moderate-to-severe renal impairment (eGFR <45 mL/min/1.73m²), severe hepatic impairment, a history of metabolic acidosis, or NYHA class III/IV heart failure are unlikely to be eligible or to benefit from participation.

Why it matters

Potential benefit: If successful, it could identify combination regimens that reduce glucose variability and improve day-to-day blood sugar control while maintaining acceptable safety.

How similar studies have performed: Previous trials of SGLT2 plus DPP-4 inhibitor or metformin combinations have demonstrated improvements in HbA1c and some reductions in glycemic variability, so this approach builds on existing evidence.
