Could a Two-Drug combo speed up delivery after pregnancy loss?
NCT ID NCT05322252
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested whether giving two medications (mifepristone and misoprostol) at the same time helps women deliver faster after a nonviable second-trimester pregnancy, compared to misoprostol alone. Thirty women between 14 and 28 weeks pregnant who needed labor induction took part. The goal was to see if more women delivered within 12 hours with the combo, while keeping safety in mind.

- What this could lead to
- If it works, this could offer a faster, safer way to complete delivery after a nonviable second-trimester pregnancy, reducing infection risk.
- What could go wrong
- This is a very small pilot study (30 people) with no long-term follow-up. Results may not apply to all situations, and the simultaneous regimen might not be faster or could increase side effects.
