Criteria

Inclusion Criteria:

  • Participant is a premenopausal female at the time of Screening.
  • Participant has a diagnosis of uterine fibroids documented by a Pelvic Ultrasound [Transabdominal ultrasound (TAU) and transvaginal ultrasound (TVU)].
  • Participant has Heavy Menstrual Bleeding (HMB) associated with uterine fibroids as evidenced by Menstrual Blood Loss (MBL) > 80 mL during each of two screening menses as measured by the alkaline hematin method.
  • Participant has negative urine and/or serum pregnancy test during Washout (if applicable) and/or Screening and just prior to first dose.
  • Participant has an adequate endometrial biopsy performed during Screening, the results of which show no clinical significant endometrial pathology.

Exclusion Criteria:

  • Participant has screening pelvic ultrasound or Saline Infusion Sonohysterography (SIS) results that show a clinically significant gynecological disorder.
  • Participant has history of osteoporosis or other metabolic bone disease.
  • Participant has clinically significant abnormalities in clinical chemistry, hematology, or urinalysis.
  • Participant has a history of major depression or post-traumatic stress disorder (PTSD) episode within 2 years of screening, OR a history of other major psychiatric disorder at any time (e.g., schizophrenia, bipolar disorder).
  • Participant is using any systemic corticosteroids for over 14 days within 3 months prior to Screening or is likely to require treatment with systemic corticosteroids during the course of the study. Over the counter and prescription topical, inhaled, intranasal or intra-articular injectable (for occasional use) corticosteroids are allowed.
