New pill takes aim at stubborn blood sugar
NCT ID NCT00814372
First seen Sep 18, 2026 · Last updated Sep 18, 2026
Summary
Researchers are testing an experimental oral drug called MBX-102 in adults with type 2 diabetes whose blood sugar remains too high on metformin alone. The trial compares two doses of MBX-102 with a placebo and with Actos, an approved diabetes drug. About 242 participants take the study drug for up to 24 weeks while staying on metformin. The main goal is to see how much MBX-102 lowers HbA1c, a marker of average blood sugar.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- MBX-102, an experimental oral drug
- What this could lead to
- If it works, MBX-102 could offer another option for people whose blood sugar stays high on metformin alone.
- What could go wrong
- This is a mid-stage trial, so researchers still need to confirm any benefit in larger studies. MBX-102 may not control blood sugar better than existing drugs, and it can cause side effects.
