NCT00744965

Brief Summary

This is a randomized prospective trial which addresses the question of whether use of an oral hypoglycemic agent as an adjunct to diet therapy in women with mild gestational diabetes will result in achieving euglycemia in a shorter period of time and, in turn, result in less frequent maternal and neonatal morbidities. This study is designed to test the hypothesis that in women with mild GDM, use of Glyburide in addition to diet and nutritional counseling lowers mean infant birth weight by 200 grams as compared with diet and nutritional counseling alone.

Study Arms (2)

Glyburide

ACTIVE COMPARATOR

Women with mild gestational diabetes will be started ADA diet and a low dose of Glyburide and their medication dosage will be titrated as necessary during the pregnancy to achieve glucose control.

Drug: Glyburide

Placebo

PLACEBO COMPARATOR

Women with mild gestational diabetes will be started ADA diet and placebo.

Drug: Placebo

Interventions

Starting dosage is 2.5 mg once daily. This dose will be titrated as necessary during the pregnancy to achieve glycemic control.

Glyburide

Sham dose adjustments of the placebo will be made.

Eligibility Criteria

Age16 Years - 45 Years
Sexfemale
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • A glucose value of ≥140 mg/dl on a 50-gram oral glucose loading test by plasma at gestational age between 24 weeks 0 days and 27 weeks 6 days based on clinical information
  • An Abnormal 3-hour oral glucose tolerance test with a fasting glucose of ≤105 mg/dl
  • Gestational age of less than or equal to 28 weeks and 0 days at the time of consent/randomization
  • Singleton gestation

You may not qualify if:

  • Established pregestational diabetes
  • Abnormal gestational diabetes testing (≥140) prior to 24 weeks 0 days of gestation. Women who have a negative glucose loading test (\<140mg/dl) before 24 weeks may still be considered for this study if they present again for glucose tolerance testing between 24 and 27 weeks.
  • Multiple gestations
  • Known major fetal anomaly or fetal demise
  • Any renal disease with serum creatinine of \>1.0
  • Known liver disease such as hepatitis
  • Maternal or fetal conditions likely to require imminent or very preterm delivery such as preeclampsia, preterm premature rupture of the membranes, preterm labor, and intrauterine fetal growth restriction
  • Known hypersensitivity or allergic reaction to Glyburide

Limitations and Caveats

Sample size of 395 limits our ability to analyze the effect of Glyburide on uncommon pregnancy outcomes. The study was underpowered for outcomes other than birth weight difference.
