Brief summary

The purpose of the proposed study is to compare - in a randomized, placebo-controlled, double-blinded trial - a combination of mifepristone and misoprostol to misoprostol used alone for missed abortion.

Detailed description

The primary aim of this trial is to compare the efficacy of mifepristone-misoprostol versus misoprostol alone for treatment of missed abortion. This will be a randomized controlled double-blinded trial of 416 women comparing misoprostol alone to mifepristone plus misoprostol for treatment of missed abortion less than 13 weeks+ 0 days LMP. All women in the trial will undergo routine screening (including ultrasound) and pre-medical induction care per standard practice at the hospital. All eligible women agreeing to participate in the study will be randomized to receive one of the following regimens: 1) STUDY GROUP ONE: 200mg mifepristone followed in 24 hours by 800mcg sublingual misoprostol; 2) STUDY GROUP TWO: placebo followed in 24 hours by 800mcg sublingual misoprostol.
