APPLE: Aspirin to Prevent Pregnancy Loss and Preeclampsia

Phase 3
Recruiting
Conditions
Pre-Eclampsia
Pregnancy Loss
Interventions
Registration Number
NCT06408181
Lead Sponsor
University of Pennsylvania
Brief Summary

The goal of this clinical trial is to investigate the effects of early initiation of double low-dose aspirin in pregnant women. The main questions it aims to answer are:

Does this dose and timing of aspirin reduce the risk of pre-eclampsia compared to standard recommendations? Does this dose and timing of aspirin reduce the risk of pregnancy loss compared to standard recommendations? Participants will begin taking at no later than 6 weeks 6 days gestational age, either 162mg of aspirin through delivery or placebo until 12 weeks and then 81mg of aspirin through delivery.

Primary Outcome Measures
NameTimeMethod
Preeclampsia with or without severe featuresfrom 20 weeks pregnancy to delivery, approximately 20 weeks

defined as two blood pressures (BPs) ≥ 140/90 mmHg at least 4 hours apart with proteinuria

Pregnancy Lossfrom enrollment to time of pregnancy loss, up to 24 weeks gestation

Pregnancy loss prior to 24 weeks gestation

Secondary Outcome Measures
NameTimeMethod
Gestational HypertensionFrom 20 weeks of pregnancy to delivery, approximately 20 weeks

Defined as two BPs ≥ 140/90 mmHg at least 4 hours apart without proteinuria

Preeclampsia without severe featuresFrom 20 weeks of pregnancy to delivery, up to 20 weeks

defined as two BPs ≥160/110 mmHg at least 4 hours apart or any of the following lab abnormalities or symptoms: platelets \<100,000/microliter, liver enzymes at least twice the normal concentration, and/or severe right upper quadrant/epigastric pain, serum creatinine \> 1.1 mg/dL or a doubling of baseline serum creatinine, pulmonary edema, or new-onset cerebral or visual disturbances (headache, blurry vision). Preeclampsia super-imposed on chronic hypertension will also be considered as part of this outcome.

Clinical pregnancy lossFrom time of first ultrasound to 20 weeks pregnancy

Defined as any pregnancy loss occurring following ultrasound confirmation of pregnancy

Composite outcome of hypertensive disorders of pregnancy or pregnancy lossFrom enrollment to end of pregnancy, up to 38 weeks

This composite outcome will include the diagnosis of any of the following: preterm preeclampsia, term preeclampsia, gestational hypertension, preeclampsia with severe features, preeclampsia without severe features, biochemical pregnancy loss, clinical pregnancy loss

Preterm preeclampsiaFrom enrollment up to 37 weeks of pregnancy, up to 37 weeks of pregnancy

Diagnosis of preterm preeclampsia, occurring prior to 37 weeks in pregnancy

Term preeclampsiaFrom 37 weeks until delivery, up to 3 weeks

Diagnosis of term preeclampsia, occurring at 37 weeks or later in pregnancy

Preeclampsia with severe featuresFrom 20 weeks of pregnancy to delivery, up to 20 weeks

Diagnosis of preeclampsia with severe hypertension and/or specific signs or symptoms of significant end-organ dysfunction

Biochemical pregnancy lossFrom enrollment to time of pregnancy loss, up to approximately 20 weeks

Defined as losses that occur prior to identification of a gestational sac via ultrasound

Preterm birthFrom enrollment to 36 weeks 6 days of pregnancy, up to delivery

Defined as delivery at less than 37 weeks gestation

Small for gestational ageAt time of delivery

Defined as a birth weight less than 10th percentile for gestational age
