Outcomes

Primary Outcomes

Percentage of Participants in Amenorrhea

Amenorrhea was defined as no bleeding intensity score greater than 1 using the Daily Diary Card during the 28 days leading up to the last day of dosing at Week 18. Bleeding intensity was graded on a 5-point scale where: 0=no bleeding to 4=heavy bleeding.

Time frame: At the end of 18 weeks Treatment Course 1

Percentage Change From Baseline in Total Uterine Fibroid System Quality of Life Survey System Severity (UFS-SSS) Score

UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. Each question was answered on a 5-point scale where 1=Not at all to 5=A very great deal. The sum of the total scores was transformed to a range of 0=no symptoms (best) to 100=most severe symptoms (worst). A negative percentage change from Baseline indicates improvement.

Time frame: Baseline to the end of 18-weeks Treatment Course 1

Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 1

UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 1: During the previous 3 months how distressed were you by "heavy bleeding during your menstrual period"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

Time frame: Baseline to the end of 18-weeks Treatment Course 1

Percentage Change From Baseline in the Individual UFS-SSS Subscale Score Question 2

UFS-SSS is an 8-question assessment tool used to measure symptom severity and has been validated as a three month look back questionnaire. The participant answered UFS-SSS subscale question 2: During the previous 3 months how distressed were you by "passing blood clots during your menstrual period"? using a 5-point scale where 1=Not at all to 5=A very great deal. A negative percentage change from Baseline indicates improvement.

Time frame: Baseline to the end of 18-weeks Treatment Course 1
