Brief Summary:

Purpose: The objective of this proposal is to study the safety and efficacy of metformin added to insulin for treatment of type 2 diabetes mellitus (T2DM) among pregnant women.

Participants: 950 pregnant women with type 2 diabetes complicating pregnancy from 10 U.S. clinical centers

Procedures (methods): Pregnant women with T2DM between 10 weeks and 22 weeks 6 days and a singleton fetus will be randomized to double-blinded insulin/placebo versus insulin/metformin. Primary outcome is composite adverse neonatal outcome (clinically relevant hypoglycemia, birth trauma, hyperbilirubinemia, stillbirth/neonatal death). Study visits monthly at clinical visits; blood draw at 24-30 weeks, newborn anthropometric measurements at less than 72 hours of life. Maternal and infant outcomes will be chart abstracted.

Metformin 1000 mg twice a day
Drug: Metformin
1000 mg twice a day
Other Names:
  • Glumetza
  • Fortamet
  • Glucophage
  • Riomet

Primary Outcome Measures :
  1. Composite adverse neonatal outcome [ Time Frame: An average of 48 hours for term infants and 30 days for preterm infants ]

    Capillary blood glucose level of < 30 mg/dL or capillary blood glucose requiring medical treatment, or

    • Birth trauma (umbilical cord artery pH < 7.0 or shoulder dystocia with brachial plexus injury), or
    • Hyperbilirubinemia requiring phototherapy, or
    • Deliver < 37 weeks' gestation, or
    • Miscarry, are stillborn, experience a neonatal demise, or
    • Large for gestational age infant (birth weight > 90th percentile for gestational age), or
    • Small for gestational age infant (birth weight < 10th percentile for gestational age) or low birth weight (< 2500 gm)

Secondary Outcome Measures :
  1. Maternal safety [ Time Frame: An average of 48 hours following delivery ]

    Adverse maternal outcomes, e.g. death, diabetic ketoacidosis, hypoglycemia requiring medical therapy, ICU admission/intubation, renal failure

    • Maternal obstetrical complications, e.g. placental abruption, preeclampsia

  2. Infant fat mass [ Time Frame: Within 72 hrs of birth ]
    Percent neonatal fat mass measured by skin-fold thickness (anthropometrics) measured at flank, biceps and sub scapular

  3. Maternal side effects [ Time Frame: Throughout study until delivery at 40 weeks gestation ]

    Maternal clinically relevant hypoglycemia defined as capillary blood glucose < 60 or < 80 with symptoms

    • Maternal side effects such as nausea, vomiting, diarrhea that cannot be managed with oral medication
