Is this trial a fit for you?
✓Likely a good fit
Pregnant individuals under 17 weeks gestation, aged 18-50, at high risk for preeclampsia, with singleton pregnancy and care at NYU Langone Health.
✕Probably not a fit
Those not at high risk for preeclampsia, with non-singleton pregnancies, or who have contraindications to aspirin may not benefit.

What this trial studies
This early-phase study examines platelet phenotypes in pregnant patients at high risk for preeclampsia who are on a standard 81 mg twice-daily aspirin. Blood samples are collected about four weeks after starting aspirin to see how the platelets respond. Eligible participants are adults 18-50, carrying a singleton pregnancy, and receiving care at NYU Langone Health, with aspirin intolerance or certain blood disorders excluding participation. The study is sponsored by NYU Langone Health and conducted at NYU Langone Health in New York.
Why it matters
Potential benefit: If successful, results could clarify how aspirin dosing influences platelet function during pregnancy and help tailor therapy to reduce preeclampsia risk.
How similar studies have gone: Previous research supports aspirin use for preeclampsia risk reduction, but this exact platelet-phenotype dosing study is exploratory.
