Study Summary

There are a few ongoing large randomized controlled trials (RCT's) on continuous glucose monitoring (CGM) in women with gestational diabetes (GDM) powered for pregnancy outcomes. However, none of these studies included women diagnosed with early GDM. The CORDELIA trial is a Belgian open-label multi-centric RCT with 14 centers in women with GDM (including both early and late GDM). Women will be randomized 1/1 to either treatment with CGM (intervention group, Freestyle Libre 3) or continue with self-monitoring of blood glucose (SMBG) with glucometer in line with normal routine (control arm). The study ends at the postpartum oral glucose tolerance test (OGTT 6-24 weeks postpartum) to screen for glucose intolerance.

Study Description

At diagnosis of GDM, women will receive education on the management of GDM with lifestyle and need to monitor glucose with SMBG. Within one week of GDM diagnosis, all participants will be asked to use a blinded CGM (Freestyle Libre Pro IQ,) during a run-phase. Women randomized to the control arm, will be asked to intermittently wear a blinded CGM sensor (Freestyle Libre Pro IQ) during 14 days at least two time points in pregnancy (at 31.0-33.6 weeks and between 36.0-38.6 weeks). For women diagnosed with early GDM (<20 weeks), blinded CGM will be needed 3 times in pregnancy with a first time at 20.0-23.9 weeks. Women randomized to the intervention arm will be recommended tu use the rt-CGM (Freestyle Libre 3) till the delivery. In line with normal routine, a 75g OGTT will be performed between 6-24 weeks postpartum to screen for glucose intolerance. Participants will be asked to also wear a blinded CGM (Freestyle Libre Pro IQ) at this last study visit.
