Drug: Estradiol/Norethindrone Acetate
Oral administration

Drug: Elagolix
Oral administration
Other Names:
  • ABT-620
  • Elagolix Sodium

Primary Outcome Measures :
  1. Percentage of Responders based on menstrual blood loss volume reduction [ Time Frame: From Month 0 (Baseline in Pivotal Study) to Final Month of Treatment Period (up through 12 months) ]
    Assessed using alkaline hematin methodology.


Secondary Outcome Measures :
  1. Change in Menstrual Blood Loss (MBL) Volume [ Time Frame: From Month 0 to Final Month (last 28 days of treatment) ]
    Assessed using alkaline hematin methodology

  2. Percentage of participants with increase in Hemoglobin [ Time Frame: Month 0 to Month 6 ]
    This assesses the concentration of hemoglobin.

  3. Percentage of participants with suppression of bleeding [ Time Frame: Up to Month 6 (during 6-Month treatment period) ]
    Suppression of bleeding is defined as having no days of bleeding (spotting is allowed) during a 28-day interval.

  4. Change in MBL Volume by Month [ Time Frame: Every Month From Month 0 (Baseline) through Month 6 ]
    Assessed using alkaline hematin methodology
