NCT05284474

Brief Summary

This is a multicentre, open-label, randomized controlled trial. A total of 340 singleton pregnancies with an EFW ≤10th percentile between 26+0 and 31+6 weeks will be recruited and randomly allocated to either the control or the intervention group. In the control group, standard Doppler-based management will be used. In the intervention group, different soluble fms-like tyrosine kinase to placental growth factor ratio (sFlt-1/PlGF) cutoffs will be incorporated to the current protocol to adjust the frequency of ultrasounds and to plan elective delivery.

Outcome Measures

Primary Outcomes (2)

  • Fetal and Neonatal complications

    stillbirth, neonatal death, artery cord pH ≤7.0, respiratory distress syndrome, required invasive ventilatory support, grade III or IV intraventricular hemorrhage, neonatal sepsis, necrotizing enterocolitis, neonatal seizures, pneumonia, meningitis, broncopulmonary dysplasia, hypoxic ischemic encephalopathy, Apgar score \<7 at 5 minutes, or elective delivery at \<28 weeks of gestation.

    During pregnancy and up to 28 days after delivery

  • Composite adverse maternal outcome

    Progression to PE with severity features; progression to hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome (LDH \>600 IU/L, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) elevated more than twice the upper limit of normal, and the platelet count less than 100 X 109/L); eclampsia, stroke, hepatic hematoma or rupture; oliguria (urine output of \<400 mL during 24 hours, or need for treatment with furosemide to maintain urine output at \>400 mL for 24 hours); cardiovascular dysfunction (need for inotropic support, left ventricle failure, or myocardial infarction); placental abruption; maternal death; maternal admission to intensive care unit \>48 hours, and/or requirement for blood transfusion.

    During pregnancy and up to 28 days after delivery

Secondary Outcomes (3)

  • Maternal perceived stress

    At inclusion and 4 weeks later

  • Other perinatal outcomes

    During pregnancy and up to 28 days after delivery

  • Number of ultrasounds per participant

    During pregnancy (before and after 37 weeks)

Study Arms (2)

Control

NO INTERVENTION

Small fetuses will be classified into 5 severity stages and managed as follows: * SGA: Estimated fetal weight (EFW) between p3 and p10 with normal Dopplers. Ultrasound/2 weeks, elective vaginal delivery at ≥39-40 weeks. * Stage I: EFW ≤p3 p or EFW p3-10 + UA PI \>p95 and/or UtA PI \>p95, and, at ≥32 weeks, CPR and/or MCA PI \<p5, in 2 occasions \>12 hours apart. Ultrasound weekly, elective vaginal delivery at ≥37 weeks. * Stage II: AEDF UA in 2 occasions \>12 hours apart. Ultrasound every 48-72h, elective Cesarean delivery at ≥34 weeks. * Stage III: DV PI \> p95 (or absent DV "a" wave) or reversed end-diastolic UA \>50% of cycles, in both cases in two occasions \> 6 hours apart. Ultrasound every 24-48h, elective Cesarean delivery at ≥30 weeks. * Stage IV: reversed DV "a" wave in two occasions \> 6 hours apart. Elective Cesarean delivery at ≥26 weeks.

Study

EXPERIMENTAL

Doppler protocol (as in controls) + sFlt-1/PlGF ratio cutoffs will be incorporated as follows: * \<38: Ultrasound biweekly in stage I FGR and every four weeks in SGA. In both cases delivery at ≥39-40 weeks. * 38-110: In stage I FGR and SGA ultrasound weekly. Delivery at ≥37 weeks. * \>110: In stage I FGR and SGA ultrasound weekly. Delivery at ≥36 weeks. * \>110 and concurrent preeclampsia: In stage I FGR and SGA ultrasound every 48h-72h. Delivery at ≥34 weeks. * \>201: Ultrasound every 48-72h, delivery at ≥34+0 weeks. If concurrent preeclampsia, delivery at ≥32+0 weeks. * \>655: Ultrasound every 48-72h, delivery at ≥32+0 weeks. If concurrent preeclampsia, delivery at ≥30+0 weeks. * \>1000: In cases with concurrent PE, delivery at ≥29+0 weeks.

Diagnostic Test: soluble fms-like tyrosine kinase to placental growth factor ratio (sFlt-1/PlGF)

Interventions

soluble fms-like tyrosine kinase to placental growth factor ratio (sFlt-1/PlGF) will be incorporated to the management of early-onset small fetuses (estimated fetal weight ≤10th percentile)
