Tranexamic acid to reduce bleeding during second-trimester dilation and evacuation

Official title: Prophylactic Tranexamic Acid for Second Trimester Dilation and Evacuation and Bleeding Outcomes: A Randomized Controlled Trial

Run by University of California, San Diego · NCT06820177 · Data updated 2026-11-12

We will test whether giving prophylactic tranexamic acid before a second-trimester dilation and evacuation reduces bleeding for people aged 18 and older at 18–24 weeks of pregnancy.

Is this trial a fit for you?

Likely a good fit

Adults (18+) requesting dilation and evacuation at 18+0 to 24+0 weeks for pregnancy termination or fetal demise who can consent, speak English or Spanish, and do not have excluded medical conditions are ideal candidates.

Probably not a fit

People with prior or current blood clots, known coagulopathy, recent anticoagulant use, severe kidney disease, chorioamnionitis/sepsis, suspected placenta accreta, or allergy to tranexamic acid may be ineligible and are unlikely to benefit from this intervention.

What this trial studies

This is a randomized, placebo-controlled trial enrolling pregnant people aged 18 and older undergoing dilation and evacuation (D&E) at 18 weeks 0 days to 24 weeks 0 days for pregnancy termination or fetal demise. Participants will be randomly assigned to receive prophylactic tranexamic acid or a placebo prior to the procedure. The primary outcome is whether tranexamic acid reduces the need for additional interventions to control bleeding at the time of D&E, and secondary outcomes include measured blood loss and other bleeding-related complications. Key exclusions include a history of thromboembolism, coagulopathy, recent anticoagulant use, severe renal impairment, active infection, suspected placenta accreta, or known allergy to tranexamic acid.

Why it matters

Potential benefit: If effective, prophylactic tranexamic acid could reduce bleeding and the need for additional procedures or transfusions during D&E, improving patient safety.

How similar studies have gone: Tranexamic acid has reduced blood loss and mortality in intrapartum and postpartum hemorrhage, but randomized data on its prophylactic use specifically for second-trimester D&E are not yet published.
