Clinical Trial Summary

The purpose of the study is to determine the efficacy of semaglutide 1mg (Ozempic®) to aid recently postpartum women with dysglycemia and a history of GDM to regress to normoglycemia; thereby filling a gap in efficacious pharmacologic intervention options for clinicians to support postpartum diabetes recovery and reduce future risk of T2DM in young women.

Description:

The diagnosis of gestational diabetes mellitus (GDM) during pregnancy identifies young women with abnormalities in pancreatic beta cell function that worsen over time, leading to diabetes. It is estimated that between 15% and 70% of women with a history GDM will progress to type 2 diabetes mellitus (T2DM). However, upon an impaired glucose tolerance test result in the early postpartum period, the American College of Obstetricians and Gynecologists only recommend considering referral for management, weight loss and physical activity counseling, considering metformin if testing results are severe enough, and yearly assessment of glycemic status. In many cases, it is possible to reverse diabetes by losing weight in the early stages before permanent, systemic damage occurs. Therefore, there is a dire need for efficacious pharmacologic intervention options in this period of postpartum diabetes recovery to return women to normoglycemia and lower future T2DM risk. Weight loss and medications that mitigate impairments in insulin secretion show the best promise for delaying or preventing T2DM, the dominant form of diabetes that develops after GDM. The primary study objective is "to examine the efficacy of semaglutide 1mg compared to placebo on regression to normoglycemia in women with dysglycemia and a recent history of gestational diabetes mellitus (i.e., 6-36 months postpartum)" to answer the research question of: "Among women with dysglycemia and a recent history of gestational diabetes mellitus, can acute treatment of semaglutide 1mg lead to regression to normoglycemia?"

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Regression to normoglycemia	Glucose tolerance to be determined by glycemic response to a 75 gram, two-hour oral glucose tolerance test (OGTT). Regression to normoglycemia is defined by fasting glucose <100mg/dL and 120 minute glucose <140 mg/dL	After 24 weeks of full-dose treatment
Secondary	Change in HbA1c	Hemoglobin to be determined	After 24 weeks of full-dose treatment
Secondary	Change in body weight	Fasted body weight after intervention minus fasted body weight at enrollment	After 24 weeks of full-dose treatment
