New pill could tame rare genetic diabetes
NCT ID NCT06976658
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new drug called dorzagliatin in 44 adults with a rare, inherited form of diabetes (GCK-MODY). The drug works by activating a key enzyme to help the body better control blood sugar. Participants will receive both the drug and a placebo at different times to see if the drug improves blood sugar levels and other measures.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Dorzagliatin (a drug that activates glucokinase, an enzyme that helps regulate blood sugar)
- What this could lead to
- If successful, this could provide a targeted oral treatment option for people with GCK-MODY, potentially improving blood sugar control without the need for insulin or other diabetes drugs.
- What could go wrong
- This is a small, early-phase (Phase 2) trial with only 44 participants, so results may not apply to everyone. The drug may not significantly improve blood sugar or could have side effects. It is not a cure, as ongoing treatment would likely be needed.
