Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. Pain score

    Pain indicated on VAS at specific time intervals during the induction to expulsion

    Time frame: at 24 hours

Secondary outcomes

  1. Efficacy

    Number of complete abortions within 24h without the need for surgery

    Time frame: after 24h from induction

  2. Time to abortion

    Time from induction (first dose of misoprostol) to expulsion

    Time frame: at 24hours

  3. Number of Participants with Adverse Events as a Measure of Safety and Tolerability

    AEs reported during the time period from mifepristone (Day 1)until follow up

    Time frame: at 6 to 8 weeks

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 18, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
