Diabetes drug switch: could a new combo improve blood sugar?
NCT ID NCT06972732
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether switching from one diabetes medication (DPP-4 inhibitor) to another (TZD) can better control blood sugar in people with type 2 diabetes who are already taking metformin and an SGLT2 inhibitor. About 204 adults will be randomly assigned to either stay on their current medication or switch to the new combination. The main goal is to see how much HbA1c (a measure of blood sugar control) changes after 24 weeks.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dapagliflozin/Pioglitazone (a combination of two drugs: dapagliflozin and pioglitazone)
- What this could lead to
- If successful, this could show that switching to a TZD (pioglitazone) provides better blood sugar control than staying on a DPP-4 inhibitor for people with type 2 diabetes already taking metformin and an SGLT2 inhibitor.
- What could go wrong
- This is a relatively small, early-stage (Phase 4) trial with only 204 participants. Results may not apply to everyone with type 2 diabetes, and the new combination may cause side effects like weight gain or fluid retention.
