CONCEPTT Trial For Women

Are you pregnant ?

Learn how CONCEPTT is working to make managing T1D easier during pregnancy!

When you are pregnant and have diabetes it is very important to keep your blood sugars as close to normal as possible. However, during pregnancy it can be difficult to control your blood sugars. When this happens, the high blood sugar levels can cause your baby to grow bigger than the average baby. This can make delivery of the baby difficult leading to potential injury for the baby as well as for you. The baby may also have problems after birth, which include breathing difficulties and low blood sugar which may require the baby to be admitted to the intensive care unit.

The standard treatment of women with type 1 diabetes who are in or planning pregnancy is the use of insulin and diet; self-monitoring of blood glucose is used to guide therapy.

This trial is trying to evaluate the benefit of adding a real-time continuous glucose monitoring (CGM) sensor to your standard therapy.

We believe that using this CGM sensor may help improve blood sugar control and baby outcomes; however, it is not yet clear whether adding CGM to the care of women planning pregnancy women with type 1 diabetes will provide better outcomes.

What is the CONCEPTT trial for pregnant women? 

This study is a randomized, open-label controlled trial funded by JDRF. This means that you will have a 50/50 chance of being assigned to receive your CGM sensor and insulin or take insulin without CGM. Both you and your caregivers, or the members of the study team, will be told whether or not you are receiving CGM.

You will use the CGM sensor until the completion of your pregnancy. You do not have to pay for the sensor. The rest of your care will stay the same. You will have the same number of visits to your obstetrician and your endocrinologist as usual.
