Clinical Trial Summary

The purpose of this study is to assess if metformin reduces adverse outcomes associated with prediabetes in pregnancy. Our hypothesis is that pregnant women with prediabetes who are treated with metformin will show a greater reduction in large for gestational age infants at birth compared to women treated with the standard of care.


Clinical Trial Description

Women in pregnancy are routinely screened for diabetes in the first trimester and those who fall into the prediabetes category by hemoglobin A1c level of 5.7 to 6.4%, fasting plasma glucose of greater than or equal to 100 to 125, or oral glucose tolerance test of greater than or equal to 140 to less than 200 before 14 weeks gestation will be approached for consent in our randomized trial. Once consent is obtained, the subjects will be randomized 1:1 into two parallel groups, the metformin treatment group and the standard of care treatment group (routine prenatal care). A random number generator will allocate the participants to the study groups. Women taking metformin will continue twice daily dosing for the duration of their pregnancy after randomization. Those in the standard of care group will receive routine prenatal care. Both groups will undergo routine gestational diabetes testing by 28 weeks. Obstetric, maternal, and neonatal outcomes will then be assessed of both groups until the 6 week postpartum visit. ;
