About this study

Official title: Pre-treatment With Mifepristone in Patients With Mirena for Optimizing Bleeding Pattern in Pre-menopausal Women

Hypothesis: Pretreatment with mifeprsitone prior to Mirena placement will induce amenorrhea and reduce bleeding irrregularities during the initial months of Mirena use.

Read the detailed description

The levonorgestrel releasing intrauterine system (IUS), Mirena, represents a highly effective contraceptive method that is cost-effective and requires limited patient effort. Furthermore Mirena offers numerous noncontraceptive benefits and addresses different medical needs for women in reproductive and non reproductive age. Side effects such as menstrual abnormalities are important reasons for early discontinuation of a contraceptive method. Irregular bleeding pattern and spotting represents a well known adverse effect during the first months of use with Mirena and corresponds to the most important factor that negatively influences the acceptability of the IUS. Up to today no standard treatment has been suggested to resolve this issue.

By inducing amenorrhea within a short period of treatment with an anti-progesterone, mifepristone, prior to insertion of Mirena, the bleeding irregularities during the first months of use might be reduced and could therefore represent an important strategy for increasing acceptability of this contraceptive system.

The purpose of the present study is to evaluate the bleeding pattern during the first months of use of Mirena in patients treated with mifepristone compared to placebo in women using Mirena for contraception. The study will also address the effect of mifepristone on endometrial morphology and breast tissue.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Days with bleeding and spotting

    To study the effect of pre-treatment with mifepristone on the initial bleeding pattern in women using LNG-IUS (Mirena)

    Measured: During the first 3 months of Mirena use

Secondary outcomes (2)
  1. Endometrial changes

    To study the effect of mifepristone pre treatment on the endometrium in women before and during treatment with Mirena with special regard to progesteron receptor modulator associated endometrial changes observed following continuos treatment with mifeprsitone (PAEC).

    Measured: 3 months post Mirena insertion

  2. Effects on breast tissue

    Breast biopsies are obtained at baseline and following 2 months treatment with mifepristone

    Measured: Evaluated at end of mifeprsitone treatment

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Mifepristone prior to Mirena in people with Women in Need of Long Acting Reversibel Cntraception With the Intrauterine Levonorgestrel Releasing System, Mirena, run by Karolinska Institutet at 1 site in Sweden.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 25 Feb 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Sweden. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Days with bleeding and spotting (time frame: During the first 3 months of Mirena use). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2016.
