Study summary

Objectives: to evaluate the efficacy, safety and quality of life by using 2.5 and mifepristone 5 mg daily doses to treat uterine fibroids over 3 months with a 9 months follow-up period.

The hypothesis of the study is that the 2.5 mg dosage resulted in a lesser reduction in fibroid size but a similar improvement in quality of life when compared to the 5 mg dose.

Read the detailed description

Women, in fertile age or in premenopausal status, presenting symptomatic uterine fibroids were randomly assigned to receive 5 mg or 10 of mifepristone.

The diminishing of prevalence of symptoms attributable to uterine fibroids is the most important goal to achieve under both treatments. The possible side effects of mifepristone are slight and women's adherence to treatment is remarkable. Also the reduction of the volumes of the uterus and fibroids contribute to enhance the wellbeing of subjects.

Terms in these criteria, in plain language(3)

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.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What researchers measure

Primary outcomes

  1. Volume of the uterine leiomyomata with 2,5mg vs 5 mg daily of mifepristone after 3 months of treatment

    Evaluate efficacy were the percentage changes in fibroid volumes before starting, 3 into treatment and 3, 6, and 9 months after its termination

    Time frame: 3 months

Secondary outcomes

  1. Volume of the uterus with 2,5 mg vs 5 md daily of mifepristone after 3 months of treatment.

    Evaluate efficacy were the percentage changes in uterus volumes before starting, 3 into treatment and 3, 6, and 9 months after its termination

    Time frame: 3 months

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 Sep 5, 2014, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
