Two diabetes drugs better than one? new trial aims to find out
NCT ID NCT06613854
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether starting two diabetes drugs early—metformin plus either oral semaglutide or empagliflozin—controls blood sugar better than metformin alone in adults recently diagnosed with type 2 diabetes. About 90 participants will take the combination or just metformin for 26 weeks. Researchers will measure blood sugar levels, weight, and other health markers to see if the combo approach is safer and more effective.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- metformin with either oral semaglutide (Rybelsus) or empagliflozin (Jardiance)
- What this could lead to
- If successful, this could show that starting two diabetes drugs early helps control blood sugar better than metformin alone, potentially improving long-term outcomes.
- What could go wrong
- This is a small, early-phase trial with only 90 participants, so results may not apply to everyone. The study is short (26 weeks), so long-term benefits or risks are unknown.
