NCT ID NCT07472179
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested two diabetes drugs, pioglitazone and metformin, in 60 women with insulin-resistant PCOS. Each woman took one drug daily for three months. Researchers measured changes in insulin resistance, waist-to-hip ratio, and hormone levels to see which drug worked better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- pioglitazone and metformin
- What this could lead to
- If pioglitazone works better than metformin, it could offer a new treatment option for women with insulin-resistant PCOS.
- What could go wrong
- This is a small, completed study with only 60 participants, so results may not apply to everyone. Both drugs have known side effects like weight gain or stomach issues.
