Eligibility Criteria
Inclusion Criteria:
- Subject is a pre-menopausal female 20 to 49 years of age.
Subject has a diagnosis of uterine fibroids documented by a pelvic ultrasound assessed by a central reader and verification that a fibroid present met the following criteria:
- At least 1 fibroid with diameter ≥ 2 cm (longest diameter), or multiple small fibroids with a total uterine volume of ≥ 200 cm³ to ≤ 2,500 cm³ (approximately 22 weeks' gestation) as documented by a centrally read ultrasound.
- Only intramural, submucosal non-pedunculated, and subserosal fibroids qualified subjects for enrollment (intracavitary pedunculated fibroids were exclusionary).

- Subject has a history of regular menstrual cycles between 24 to 35 days.
- Subject has heavy uterine bleeding associated with uterine fibroids as evidenced by blood loss > 80 mL during 2 screening menstrual cycles, measured by the alkaline hematin method.
Exclusion Criteria:
- Subject has had a myomectomy, uterine artery embolization, or high intensity focused ultrasound for fibroid destruction within 1 year prior to randomization or any history of endometrial ablation.
- Subject has a history of osteoporosis or other metabolic bone disease.
- Subject shows evidence of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric (including depression), or neurologic diseases or any uncontrolled medical illness such as uncontrolled type 2 diabetes.
