Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Rationale: Gestational diabetes is currently treated by the one-size-fits-all-approach. Treatment efficacy is poorly defined and inconsiderate of patients clinical presentation Objective: To characterize the efficacy of pharmacological treatment of gestational diabetes mellitus between patients with distinct metabolic phenotypes Study design: Prospective observational study, in metformin-treatment efficacy is compared between patients with GDM caused by insulin resistance and patients with GDM caused by low insulin secretion.

Study population: A prospective cohort of 103 women with diagnosed gestational diabetes mellitus treated by metformin.

Main study parameters/endpoints: Primary outcomes is the glucose-disposition-index in late pregnancy (35-37 weeks gestation) and requirement for supplemental insulin-treatment. Secondary outcomes include insulin sensitivity (Matsuda-index), insulin secretion (Stumvoll-index), HbA1c, gestational weight gain, body composition, physical activity, eating behavior, plasma biomarkers, glucose control, and maternal and infant pregnancy outcomes.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Low insulin sensitivity

Women will be classified as having low insulin sensitivity, if their Matsuda-index is in the lowest quartile of a reference cohort

Metformin

Intervention Type DRUG

All patients are diagnosed with gestational diabetes and treated with metformin (per routine clinical practice

Low insulin secretion

Women will be classified as having low insulin secretion if their Stumvoll-index is in the lowest quartile of a reference cohort

Metformin

Intervention Type DRUG

All patients are diagnosed with gestational diabetes and treated with metformin (per routine clinical practice
