Treatment of Heavy Menstrual Bleeding in Women With Uterine Fibroids


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This is a randomized controlled trial (RCT) to assess the comparative effectiveness of Levonorgestrel Intrauterine System (LNG-IUS) to Tranexamic Acid (TA) for the treatment of heavy menstrual bleeding (HMB) in women with clinically-significant fibroids.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

  • Able to give consent for inclusion in the study.
  • Understands the English language for consent and questionnaires.
  • Self-reported HMB 3 months or more.
  • Not pregnant or breast-feeding.

Exclusion Criteria:

  • Class 0 fibroids confirmed by hysteroscopy, saline infused sonogram, or 3D ultrasound.
  • Uterine sounding length >14 cm.
  • Abnormal biopsy (pre-malignant or malignant) or incomplete clinical testing to rule out malignancy.
  • Venous thromboembolic history, clotting disorder, strong family history of venous thromboembolic events.
  • Needs hormonal contraception, including estrogen-containing medications.
  • Uterine size >20 weeks gestational size.
  • Breast, uterine or cervical malignancy.
  • Liver disease or liver tumor.
  • Pelvic inflammatory disease or infection with gonorrhea or chlamydia in last 3 months.
