The Misoprostol-Only Regimen Evidence Study

Sponsor: Ibis Reproductive Health

View on ClinicalTrials.gov

Summary

The goal of this study is to evaluate the effectiveness, non-inferiority, and side-effect profile of an updated misoprostol-only regimen, as compared to the combined mifepristone-misoprostol regimen, among people seeking medication abortion (MAB) through 77 days of pregnancy in telehealth and in-person settings. The investigators aim to evaluate this in both in-clinic and telehealth medication abortion care in the United States. The main questions it aims to answer are: 1. What proportion of pregnant people using an updated misoprostol-only medication abortion regimen have a complete abortion using just the prescribed pills? 2. Is the updated misoprostol-only medication abortion regimen no more than 5% less effective (non-inferior) than the standard combined medication abortion regimen? 3. What is the pattern of beta hCG decline following use of a misoprostol-only medication abortion through 77 days of pregnancy? Participants will: * be randomized to one of two medication regimens (misoprostol-only or the combined regimen) in a 1:1 ratio based on duration of pregnancy at enrollment. - self-report outcomes via daily surveys for the first 3 days, and thereafter weekly at 7, 14, 21, 28, and 35 days. * return to the clinical site for tests as instructed The investigators hypothesize that the proportion with complete abortions in the misoprostol-only arm will be non-inferior to the proportion with complete abortions in the combined regimen arm within a 5% margin of inferiority

Interventions

DRUG

Misoprostol-only medication abortion regimen

This intervention is an updated misoprostol-only regimen that involves being counseled on and receiving medications for a medication abortion using 3-4 doses of 800μg misoprostol administered sublingually every 3 hours.

DRUG

Combined regimen

This intervention will involve participants being counseled on and receiving medications for a medication abortion regimen of mifepristone (200mg orally) followed 24-48 hours later by misoprostol (800μg b/v) with a second dose of misoprostol (800μg b/v) taken 3 hours later only for those 64-77 days.
