NCT06628453

Brief Summary

The goal of this clinical trial is to learn if continuous glucose monitoring works better than self-monitoring of blood glucose (fingersticks) to treat type 2 diabetes in pregnancy. It will also learn about all risk factors (biologic, personal, social) for maternal and infant complications in type 2 diabetes pregnancies. The main questions it aims to answer are:

  1. 1.Does continuous glucose monitoring improve infant outcomes compared to self-monitoring of blood glucose?
  2. 2.Does continuous glucose monitoring improve maternal diabetes control and other maternal outcomes compared to self-monitoring of blood glucose?
  3. 3.What other factors increase the risk of maternal and infant complications?
  4. 4.Use continuous glucose monitoring or self-monitoring of blood glucose to monitor blood sugar control from enrollment until delivery
  5. 5.Have blood drawn at enrollment, 24 weeks, 34 weeks and delivery to measure hemoglobin A1c levels and store blood for future analysis
  6. 6.Complete surveys about social support, environmental stressors, diabetes distress and glucose monitoring satisfaction at research visits
  7. 7.Have umbilical cord blood collected at delivery for analysis

Outcome Measures

Primary Outcomes (2)

  • Time in Range (TIR) at 34 weeks gestation

    Percentage of time spent within target range (63-140mg/dL) on Continuous Glucose Monitoring at 34 weeks gestation

    33 to 35 weeks gestation

  • Composite Neonatal Morbidity

    Composite morbidity of the neonate including one or more of preterm birth (delivery less than 37 weeks for any indication), birth trauma (shoulder dystocia with nerve injury, clavicular or humeral fracture or 3 or more maneuvers to resolve), hypoglycemia (requiring treatment with dextrose gel or IV within 24 hours of birth), hyperbilirubinemia (requiring phototherapy within 72 hours of birth), large-for-gestational-age infant (birthweight greater than the 90th percentile for gestational age), and miscarriage, stillbirth or neonatal death prior to hospital discharge.

    From the date of delivery to the date of neonatal hospital discharge, assessed up to 12 months of life

Secondary Outcomes (30)
