Could a simple pill replace painful shots for new moms at risk of clots?
NCT ID NCT07716332
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study compares two blood-thinning medicines given after delivery to prevent dangerous blood clots: apixaban (a pill taken twice a day) and enoxaparin (a daily shot). The trial enrolls women at high risk for clots after vaginal or cesarean birth. The main goal is to see which treatment is more convenient and easier for mothers to stick with, while also tracking safety and effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- apixaban (oral tablet) compared to enoxaparin (subcutaneous injection)
- What this could lead to
- If oral apixaban works as well as the injection, it could offer new mothers a simpler, less painful way to prevent dangerous blood clots after childbirth.
- What could go wrong
- This is a small study focused on convenience, not on proving apixaban prevents clots better. It may not detect rare safety issues like bleeding.
