Medical Abortion With Mifepristone + Misoprostol (13 - 22 Weeks)

Phase 4
Completed
Conditions
Complete Uterine Evacuation After Use of Study Drugs
Interventions
Registration Number
NCT01768299
Lead Sponsor
Gynuity Health Projects
Brief Summary

A double-blind randomized controlled trial to compare a shorter interval between the administration of mifepristone and misoprostol (simultaneous administration compared to 24hours from administration of mifepristone to receipt of the first dose of misoprostol) for termination of pregnancy up to 13-22 weeks of gestation. The investigators hypothesize that a shortened interval may achieve comparable efficacy in terminating pregnancy, whilst reducing the duration of the procedure and in turn, the duration of hospitalization.

Mifepristone and first dose of misoprostol simultaneously.MisoprostolWill receive study packet one containing placebo to swallow at home on study day 1. They will be told to return to the hospital for induction and will be scheduled to return to the hospital 24 hours later. Upon their return, they will be hospitalized and receive another study packet containing mifepristone. Simultaneously they will receive one dose of 400 mcg buccal misoprostol. Women will remain hospitalized and receive repeated doses of 400 mcg buccal misoprostol every three hours. Participants will receive up to eight doses of misoprostol (e.g. 3200 mcg misoprostol) over 24 hours. Misoprostol dosing will stop when both the fetus and placenta are expelled. The procedure will be considered complete once both the fetus and placenta are expelled.
