Examining anticoagulation in pregnant women using Lovenox three times a day

Anticoagulation Profile in Pregnant Women Treated With Three Times a Day of Low Molecular Weight Heparin (LMWH)

Phase 4 Interventional University of California, Irvine · NCT04861103

This study tests if giving pregnant women Lovenox three times a day helps keep their blood thinner and safer from clots compared to the usual twice-daily dose.

What this trial studies

This study investigates the anticoagulation profile of pregnant women who are treated with low molecular weight heparin (Lovenox) administered three times a day. Given the increased risk of blood clots during pregnancy, the study aims to determine if more frequent dosing can achieve adequate medication levels throughout the day. The research focuses on women who require therapeutic doses of Lovenox and evaluates the effectiveness of this dosing strategy compared to traditional twice-daily dosing. The study is conducted at the University of California, Irvine.

Who should consider this trial

Good fit: Ideal candidates are nulliparous or multiparous women aged 18 or older with a single intrauterine pregnancy requiring therapeutic low molecular weight heparin.

Not a fit: Patients who are pregnant with multiples, under 18 years old, have a history of Heparin Induced Thrombocytopenia, or are allergic to enoxaparin may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the risk of blood clots in pregnant women by ensuring more consistent anticoagulation levels.

How similar studies have performed: While there is limited data on this specific dosing strategy, previous studies indicate that many patients do not achieve adequate anticoagulation levels with current dosing recommendations, suggesting a need for further investigation.
