The Feasibility Of Expectant Management Versus Induction At 38 Weeks Among Individuals With Gestational Diabetes Mellitus: A Randomized Controlled Pilot Trial (EAGER Pilot Trial)

The EAGER pilot trial is designed to assess the feasibility of a Canadian, multicentre prospective randomized open-label blinded end-point (PROBE) clinical trial addressing whether induction of labour (IOL) at 38 weeks' gestation compared to expectant management (EM) reduces severe perinatal mortality and morbidity among individuals with gestational diabetes mellitus (GDM). Eligible participants will be consented between 32 weeks + 0 days and 38 weeks + 0 days gestation and randomized between 36 weeks + 0 days and 38 weeks + 0 days gestation. Participants will be randomized to one of two arms: * Intervention Arm: IOL between 38 weeks + 0 days and 38 weeks + 6 days OR * Control Arm: EM without intervention until spontaneous labour, or earlier if a medical indication arises. A total of 260 participants (130 per group) will be recruited from Canadian sites, where participants will have 3 study visits: 1. Enrollment and randomization 2. After delivery and up to 72 hours postpartum 3. 6 weeks postpartum At enrollment and randomization, patient-reported baseline and clinical data from medical charts will be collected. Upon admission to hospital for labour and delivery, a blood sample may be collected to assess HbA1C and plasma glucose levels. After delivery and up to 72 hours postpartum, study feasibility will be assessed through patient-reported outcomes and administrative and clinical data. At 6 weeks postpartum, participants will be surveyed for secondary health resource use. Findings from this pilot will inform the design, implementation and feasibility of a future full-scale randomized controlled trial.
