Early-onset preeclampsia (PE), defined as preeclampsia presenting before 34 weeks of gestation, is a severe placental disorder associated with significant maternal and perinatal morbidity. There is currently no disease-modifying treatment; management relies on close surveillance and delivery, frequently resulting in extreme prematurity. Recent laboratory research identified ferroptosis, a form of iron-dependent regulated cell death driven by lipid peroxidation, as a key mechanism of placental injury in early-onset preeclampsia. A high-throughput drug screen identified dipyridamole, an approved oral antiplatelet and vasodilatory agent, as a potent ferroptosis inhibitor in primary human trophoblast cultures (EC50 = 0.146 µM), acting through mechanisms independent of its known phosphodiesterase-inhibitory pharmacology. In preeclamptic placental explants, dipyridamole markedly reduced release of sFlt-1, a central mediator of the maternal syndrome. Dipyridamole carries an established pregnancy safety record supported by randomized trials and a Cochrane meta-analysis of antiplatelet agents in pregnancy. This is a prospective, single-center, open-label pilot study using a sequential, fixed dose-escalation design. The study will enroll 15 hospitalized pregnant women with early-onset preeclampsia (gestational age 26+0 to 33+6 weeks) and an elevated sFlt-1/PlGF ratio (≥85), for whom expectant management is clinically appropriate. Enrollment proceeds through a staged sentinel design w…
