Is this trial a fit for you?

Likely a good fit

Women up to 13 weeks' gestation with a single intrauterine missed miscarriage who are planning termination and have no prior cesarean or uterine scar would be ideal candidates.

Probably not a fit

People with prior cesarean section or other uterine scarring, multiple pregnancy, or pregnancies beyond 13 weeks are excluded and would not be expected to benefit from this protocol.

What this trial studies

This randomized, controlled Phase 4 trial will enroll 92 women with a single missed miscarriage up to 13 weeks' gestation and assign them to receive either letrozole for three days followed by vaginal misoprostol or misoprostol with a placebo. The main outcomes are the rate of complete uterine evacuation and the time to expulsion after treatment. Women with a prior cesarean section or other uterine scar are excluded. Care and follow-up visits are conducted at Nishtar Medical University and Hospital in Multan.

Why it matters

Potential benefit: If successful, the combination could raise the chance of a complete medical management of missed miscarriage and reduce the need for surgical procedures.

How similar studies have gone: Smaller trials and observational reports using letrozole or other pretreatments before misoprostol for early pregnancy termination have shown mixed but sometimes promising improvements in expulsion rates, so evidence is limited but suggestive.
