Comparator Trial Using Insulin Glulisine vs. Insulin Lispro for Treatment of Gestational Diabetes
- Conditions
- Diabetes During Pregnancy
- Interventions
- Registration Number
- NCT01662921
- Lead Sponsor
- Sansum Diabetes Research Institute
- Brief Summary
We hypothesize that insulin glulisine is non-inferior to currently proven rapid-acting insulin lispro when used in a basal/bolus regimen to treat hyperglycemia in patients with gestational diabetes mellitus.
- Detailed Description
To date, only two rapid-acting insulin analogs have been shown to be safe and effective for the treatment of diabetes during pregnancy: insulin aspart and insulin lispro.
The pharmacokinetics and pharmacodynamics of insulin glulisine are unique and insulin glulisine may be the best rapid-acting analog for the treatment of post-prandial hyperglycemia. We believe that insulin glulisine should be evaluated in women with gestational diabetes for its potential efficacy.

Group Intervention Description NPH and insulin lispro NPH Patients diagnosed with diabetes during pregnancy will be randomized to long acting insulin NPH and short acting insulin lispro in a basal bolus regimen to treat post prandial hyperglycemia using a dosing schedule of 50% NPH calculated by the patients weight and gestational age and 50% lispro pending their last three SMPG average. NPH and insulin glulisine NPH Patients with a diagnosis of diabetes during pregnancy will be randomized to using long acting insulin NPH and short acting insulin glulisine as treatment for post prandial hyperglycemia with a 50% NPH dosing schedule based on the weight and gestational age and 50% glulisine schedule based on their last three SMBG result average. NPH and insulin lispro Insulin LISPRO Patients diagnosed with diabetes during pregnancy will be randomized to long acting insulin NPH and short acting insulin lispro in a basal bolus regimen to treat post prandial hyperglycemia using a dosing schedule of 50% NPH calculated by the patients weight and gestational age and 50% lispro pending their last three SMPG average. NPH and insulin glulisine Insulin glulisine Patients with a diagnosis of diabetes during pregnancy will be randomized to using long acting insulin NPH and short acting insulin glulisine as treatment for post prandial hyperglycemia with a 50% NPH dosing schedule based on the weight and gestational age and 50% glulisine schedule based on their last three SMBG result average.
- Primary Outcome Measures
Name Time Method show that insulin glulisine is non-inferior to insulin lispro in a basal/bolus regimen to treat hyperglycemia in patient with gestational diabetes mellitus week 4 of insulin treatment compare average 1-hour post prandial SMBG measurements between patients randomized to insulin glulisine or insulin lispro
- Secondary Outcome Measures
Name Time Method Serum blood glucose area under the curve (AUC) at one 4-hour in-clinic meal challenge week 2 of insulin treatment patients will come to the study site under fasting conditions and eat a standardized meal in the morning post administration of insulin NPH and their randomized bolus insulin.
Compare A1C at enrollment and weekly until delivery up to 36 weeks A1C is measured weekly at each pregnancy visit up to 26 visits. Subjects are enrolled at 20-32 weeks gestation and have weekly visits to obtain A1C through delivery, and again at the 6-week postpartum visit.
Compare incidence of hypoglycemic episodes <60 mg/dL with symptoms up to 36 weeks Hypoglycemic episodes since the last visit will be reported at each pregnancy visit, usually weekly, from enrollment at 10-30 weeks gestation through delivery and at the 6-week postpartum visit if continuing to take insulin.
