De klinische studie NCT07462793 (COMET-GDM) is een interventioneel studie bij Neonatale hypoglykemie, Zwangerschapsdiabetes mellitus (GDM) met de status nog niet rekruterend. De inclusie van 120 deelnemers start op 1 maart 2026. De studie wordt geleid door Institute of Mother and Child, Warsaw, Poland en de voltooiing is gepland op 1 december 2027. Laatste update op ClinicalTrials.gov: 10 maart 2026.
Beknopte samenvatting
The purpose of this study is to determine whether continuous glucose monitoring (CGM) improves the detection and management of neonatal hypoglycaemia in newborns of mothers with insulin-treated gestational diabetes.
Uitgebreide beschrijving
Gestational diabetes mellitus (GDM) is a form of glucose intolerance affecting up to 14% of pregnant women and is associated with an increased risk of multiple maternal and fetal complications. This risk is proportional to the degree of maternal hyperglycaemia. Appropriate glycaemic control and dietary management are key components of GDM treatment. However, in approximately 10-30% of cases, pharmacological therapy i...Toon meer

ExperimenteelContinuous glucose monitoring
Neonates undergo continuous glucose monitoring (CGM), with real-time glucose values visible to the clinical team. CGM data may be used to support the detection and clinical management of neonatal hypoglycaemia in accordance with the study protocol.
Dexcom ONE Continuous Glucose Monitoring System
The Dexcom ONE continuous glucose monitoring system is applied to all participants. Following randomisation, CGM data are either available in real time to the clinical team (intervention group) or recorded in masked mode and not available to the clinical team, and therefore do not influence clinical management (control group).
Actieve comparatorBlood glucose testing based on standard care procedures
Detection and management of neonatal hypoglycaemia are based on standard care procedures, as defined by the local protocol. Additionally, neonates undergo continuous glucose monitoring (CGM) in masked mode. CGM values are not visible to the clinical team and do not guide clinical decision-making.

Primaire uitkomst
UitkomstmaatBeschrijving van de uitkomstmaatTijdsbestek
Neonatal hypoglycaemia
Number of hypoglycaemic episodes per neonate, defined as the number of CGM-recorded glucose values \<40mg/dl (2.2 mmol/L) occuring within the first 72 hours after birth.
From birth until 72 hours of life
Secundaire uitkomst
UitkomstmaatBeschrijving van de uitkomstmaatTijdsbestek
Total cumulative duration of hypoglycaemia per neonate within the first 72 hours of life
Total cumulative duration of hypoglycaemia per neonate within the first 72 hours of life, defined as the sum of all time periods during which CGM-measured glucose concentration is \<40 mg/dL (2.2 mmol/L), expressed in minutes.
From birth until 72 hours of life
Number of hypoglycaemia-related clinical interventions per neonate during the monitoring period
Number of clinical interventions (feeding, oral glucose, intravenous glucose administration) per neonate during the monitoring period due to hypoglycaemia
