Semaglutid för behandling av glukosintolerans hos kvinnor med tidigare graviditetsdiabetes (SERENA)
Semaglutid för behandling av glukosintolerans hos kvinnor med tidigare graviditetsdiabetes: en dubbelblind RCT
Studieöversikt
Status
Intervention / Behandling
Detaljerad beskrivning
Patientpopulation: Kvinnor med en nyligen anamnes på graviditetsdiabetes (GDM) och ihållande glukosintolerans i tidig postpartum är en särskilt högriskgrupp, där cirka 50 % utvecklar typ 2-diabetes (T2DM) inom 5 år efter förlossningen. Semaglutid är en långverkande glukagonliknande peptid-1 (GLP-1) agonist med flera fördelaktiga metaboliska effekter, inklusive glukossänkande effekt, viktminskning och kardiovaskulära skyddande effekter. Vi antar att hos kvinnor med tidigare GDM och glukosintolerans i tidig postpartum, kommer behandling med semaglutid att minska risken för att utveckla T2DM på lång sikt jämfört med placebo.
Intervention och jämförelse: Belgisk multicentrisk dubbelblind RCT med 12 centra för att jämföra semaglutid (en gång i veckan) med placebo hos kvinnor med nyligen anamnes på GDM och glukosintolerans [försämrad fasteglykemi (IFG) och/eller nedsatt glukostolerans (IGT) ] 6-24 veckor efter förlossningen. Deltagarna kommer att randomiseras till 1/1 till semaglutid eller placebo på en bakgrund av livsstilsmått. Semaglutid kommer att titreras upp till 1 mg/vecka under en 8-veckorsperiod. Deltagarna kommer att följas upp i 3 år. Deltagarna kommer att få ett oralt glukostoleranstest på 75 g (OGTT) 3 månader efter det att interventionen avslutats. Randomisering kommer att stratifieras enligt BMI vid det tidiga postpartumbesöket (
Resultat: Det primära effektmåttet är utvecklingen av T2DM definierad av OGTT och/eller HbA1c. Viktiga sekundära effektmått inkluderar behovet av räddningsterapi för diabetes, regression till normoglykemi, viktminskning, betacellsfunktion, insulinresistens och det metabola syndromet. För att uppnå 80 % effekt planerar vi en provstorlek på 206 för att upptäcka en uppskattad 50 % minskning av risken för att utveckla T2DM mellan båda grupperna, förutsatt en 30 % förlust för uppföljning under studien.
