Comparator Trial Using Insulin Glulisine vs. Insulin Lispro for Treatment of Gestational Diabetes

Phase 2
Completed
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.

GroupInterventionDescription
NPH and insulin lisproNPHPatients 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 glulisineNPHPatients 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 lisproInsulin LISPROPatients 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.

Primary Outcome Measures
NameTimeMethod
show that insulin glulisine is non-inferior to insulin lispro in a basal/bolus regimen to treat hyperglycemia in patient with gestational diabetes mellitusweek 4 of insulin treatment

compare average 1-hour post prandial SMBG measurements between patients randomized to insulin glulisine or insulin lispro

Secondary Outcome Measures
NameTimeMethod
Serum blood glucose area under the curve (AUC) at one 4-hour in-clinic meal challengeweek 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 deliveryup 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 symptomsup 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.
