Could a common fertility drug improve miscarriage care?
NCT ID NCT07160855
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests whether taking letrozole before misoprostol helps women with missed miscarriage pass pregnancy tissue more completely than misoprostol alone. Ninety-two women in early pregnancy (up to 13 weeks) will be randomly assigned to receive either letrozole or a placebo for three days, followed by misoprostol. The main goal is to see if the combination leads to a complete abortion within 24 hours without needing surgery.
