In EPF, the sequential combination of mifepristone with misoprostol is superior to the use of misoprostol alone in terms of complete evacuation of products of conception, patient satisfaction, complications, side effects and costs.

Complete evacuation/ succesful treatment<br>
Whether or not complete evacuation (total endometrial thickness <15 mm) has been acquired will be assessed 15-20 days after the initial treatment. If so, this will be considered a complete evacuation and thus successful treatment. If the total endometrial thickness is ≥ 15 mm, ultrasonography will be repeated six weeks after initial treatment. Once again, if the total endometrial thickness is <15 mm this will be considered as a complete evacuation and thus a successful treatment.
Achtergrond van het onderzoek
This study will test the hypothesis that, in EPF, the sequential combination of mifepristone with misoprostol is superior to the use of misoprostol alone in terms of complete evacuation of products of conception (primary outcome), patient satisfaction, complications, side effects and costs (secondary outcomes). The trial will be performed multi-centred (hospitals), prospectively, two-armed, randomized, double-blinded and placebo-controlled.
Women with ultrasonographically confirmed EPF (6-14 weeks postmenstrual), managed expectantly for at least one week, can be included. Before medical treatment with misoprostol (two doses 400mcg (four hours apart), repeated after 24 hours if no tissue is lost), patients will be randomized to oral mifepristone (600mg) or oral placebo (identical in appearance). We aim to randomize 460 women in a 1:1 ratio, stratified by centre.
After six weeks, the primary endpoint, complete or incomplete evacuation, will be determined. An endometrial thickness <15mm (maximum anterior-posterior diameter) by ultrasonography and no evidence of retained products of conception using only the allocated therapy, is considered as successful treatment result. Secondary outcome measures are registered using the case report form, a patient diary and validated digital questionnaires.
Doel van het onderzoek
In EPF, the sequential combination of mifepristone with misoprostol is superior to the use of misoprostol alone in terms of complete evacuation of products of conception, patient satisfaction, complications, side effects and costs.
Onderzoeksopzet
Ultrasound will be performed 15-20 days after initial treatment. If treatment is not successful at that time another ultrasound wil be performed six weeks after initial treatment.
Onderzoeksproduct en/of interventie
Before medical treatment with misoprostol (two doses 400mcg (four hours apart), repeated after 24 hours if no tissue is lost), patients receive oral mifepristone (600mg).
The control arm receives an oral placebo.
