Can a hormone blocker make miscarriage care more complete?
NCT ID NCT06452719
First seen Aug 10, 2026 · Last updated Aug 11, 2026 · Updated 1 time
Summary
This pilot study explores whether taking letrozole for three days before using misoprostol can improve the medical management of early pregnancy loss. The goal is to see if this combination more completely empties the uterus, potentially reducing the need for additional procedures. Adults with a confirmed first-trimester loss will receive the treatment and be followed for effectiveness, side effects, and how acceptable they find it.

- What this could lead to
- If effective, this combination could offer a more complete, less invasive option for managing early pregnancy loss, potentially reducing the need for surgical procedures.
- What could go wrong
- This is a small pilot study, so results may not be definitive or generalizable. Side effects and the need for additional interventions remain possible.
