Study summary

A randomized comparison of glyburide to glucovance (metformin -glyburide) in the management of diabetes in pregnancy.

Read the detailed description

This study will be a randomized open label trial of glyburide compared to glucovance in the management of gestational diabetes. We hypothesize that glucovance will provide improved glycemic control and a lower failure rate with no increase in neonatal adverse outcomes. Sixty-seven patients will be randomized by computer to each arm of the study. Outcomes will be glycemic control, failure rate of the drug to achieve glycemic goals, and neonatal outcomes.

Study arms

  • Active comparator
    Glyburide

    * Patients will check and record blood glucose fasting and 1 hour after each meal each day. Patients will also keep a diary of all meals. * The starting dose of glyburide may be 2.5milligrams (mg) to 5mg every day(QD) or twice daily (BID) depending on the degree of hyperglycemia. * The dose of glyburide will be increased as needed to a maximum of 20mg /day. * Antenatal testing will be initiated at 28 weeks * Patients will receive monthly growth scans

    Drug: Glyburide

  • Active comparator
    Glucovance

    * Patients will check and record blood glucose fasting and 1 hour after each meal each day. Patients will also keep a diary of all meals. * The starting dose of glucovance may be 1.25/250milligrams (mg) either once daily (QD) or twice a day (BID) increased to a maximum of 20mg/2000mg as needed. * Patients will receive monthly growth scans * Antenatal testing will be initiated at 28 weeks.

    Drug: Glucovance

Interventions

  • DrugGlyburide

    glyburide 2.5milligrams (mg) at bedtime (qhs) increased as needed to a maximum of 20mg/day usually taken twice a day (BID)

    Also known as: micronase, diabeta, glynase

  • DrugGlucovance

    glucovance (2.5/500) 1 taken orally (PO) at bed time (QHS) increased as needed to a maximum dose of (20/2000)/day usually taken twice a day (BID)

    Also known as: combination glyburide and metformin

What researchers measure

Primary outcomes

  1. efficacy of glyburide compared to glucovance

    failure rate of glyburide compared to glucovance in ability to achieve euglycemia

    Time frame: during the index pregnancy

Secondary outcomes

  1. maternal hypoglycemia

    the rate of maternal hypoglycemia associated with each drug

    Time frame: during the index pregnancy

  2. neonatal birthweight

    infant weight at birth

    Time frame: at birth

  3. neonatal apgar scores

    infant 1 minute and 5 minute apgar scores

    Time frame: at birth

  4. neonatal admission to the newborn intensive care unit (NICU)

    admission to the Newborn intensive care unit (NICU)

    Time frame: at birth or within the first 24 hours after birth

  5. neonatal hypoglycemia

    failure of the neonate to maintain blood glucose \> 60 milligrams/deciliter (mg/dl)

    Time frame: up to 24 hours after delivery
