October 7, 2020 updated by: Texas Tech University Health Sciences Center, El Paso

Glyburide vs Glucovance in the Treatment of Gestational Diabetes

A randomized comparison of glyburide to glucovance (metformin -glyburide) in the management of diabetes in pregnancy.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This study will be a randomized open label trial of glyburide compared to glucovance in the management of gestational diabetes. We hypothesize that glucovance will provide improved glycemic control and a lower failure rate with no increase in neonatal adverse outcomes. Sixty-seven patients will be randomized by computer to each arm of the study. Outcomes will be glycemic control, failure rate of the drug to achieve glycemic goals, and neonatal outcomes.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
efficacy of glyburide compared to glucovance
Time Frame: during the index pregnancy
failure rate of glyburide compared to glucovance in ability to achieve euglycemia
during the index pregnancy

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
maternal hypoglycemia
Time Frame: during the index pregnancy
the rate of maternal hypoglycemia associated with each drug
during the index pregnancy
neonatal birthweight
Time Frame: at birth
infant weight at birth
at birth
neonatal apgar scores
Time Frame: at birth
infant 1 minute and 5 minute apgar scores
at birth
neonatal admission to the newborn intensive care unit (NICU)
Time Frame: at birth or within the first 24 hours after birth
admission to the Newborn intensive care unit (NICU)
at birth or within the first 24 hours after birth
neonatal hypoglycemia
Time Frame: up to 24 hours after delivery
