Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are pregnant women diagnosed with gestational diabetes mellitus who are being treated with metformin.
✕Probably not a fit
Patients with pre-existing diabetes or those on medications that affect study outcomes prior to their GDM diagnosis may not benefit from this study.

What this trial studies
This observational study aims to evaluate the effectiveness of metformin in treating gestational diabetes mellitus (GDM) by comparing treatment outcomes between patients with different metabolic profiles. It focuses on women diagnosed with GDM, specifically those experiencing insulin resistance versus those with low insulin secretion. The study will track various parameters, including glucose levels, insulin sensitivity, and weight gain, to better tailor treatment approaches for pregnant women with GDM. A total of 103 participants will be monitored during late pregnancy to assess the need for additional insulin treatment.
Why it matters
Potential benefit: If successful, this study could lead to more personalized and effective treatment strategies for managing gestational diabetes, improving outcomes for both mothers and babies.
How similar studies have gone: While there have been studies on gestational diabetes treatment, this approach focusing on distinct metabolic phenotypes is relatively novel and has not been extensively tested.
