Gestational Diabetes MellitusPhase 4NCT01563120
A Comparison Between Two Oral Hypoglycemics - Metformin and Glybenclamide for the Treatment of Gestational Diabetes Mellitus
A Phase 4 study testing metformin and glybenclamide in people with Gestational Diabetes Mellitus, run by HaEmek Medical Center, Israel at 1 site in Israel.
Trial summary
Rationale Gestational diabetes mellitus (GDM) complicates 5-7% of pregnancies. Major hazards include macrosomia, polyhydramnios, labor trauma and neonatal hypoglycemia.

About this study
Rationale Gestational diabetes mellitus (GDM) complicates 5-7% of pregnancies. Major hazards include macrosomia, polyhydramnios, labor trauma and neonatal hypoglycemia. The ADA and ACOG recommend glucose control in order to reduce the incidence of hyperglycemia induced complications. Glucose control can be achieved using diet and life style changes. Insulin is initiated in women who fail to obtain glucose control with diet alone. During the past 11 years oral hypoglycemic drugs have been tested and proven to be efficacious and safe.
Objectives
Read more
- To compare the efficacy and safety of glybenclamide vs. metformin in the treatment of women diagnosed with GDM
- To evaluate the improvement in glycemic control after the addition of a second oral hypoglycemic drug after failure of the first
Hypothesis GDM is one of the major conditions contributing to obstetrical complications and prenatal morbidity. Improving glycemic control, by means of improving compliance and patient satisfaction, will decrease obstetrical complications, maternal and neonatal morbidity and have positive long term health implications.
Study design Prospective, randomized, open label
Study population Women between the ages 18-45, diagnosed with GDM will be recruited. GDM will be defined by a pathological OGTT (according to Carpenter and Coustan criteria) performed at or after 13 weeks of gestation.
Study period From recruitment until discharge of the newborn baby after delivery
Study protocol Women will be randomized at recruitment. Demographic and obstetrical data will be collected. Average glucose levels during the previous two weeks, estimated fetal weight and amniotic fluid index, and lab exams reflecting glycemic control will be noted. Women will provide daily glucose levels via fax or mail once a week. Glycemic control will be evaluated by a daily chart, including 7 measurements: 3 preprandial, 3 postprandial and a 7th measurement at 10 pm. Women will be invited to a monthly follow-up, which will include a sonographic evaluation of fetal weight and amniotic fluid, and lab exams. Follow-up protocol after 38 w of gestation will be according to our ward's protocol. The study was approved by the local Helsinki committee.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Israel. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
glycemic control (time frame: 2 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01563120, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Nov 2016.
