A Phase III, Randomised, Parallel Group, Double-blind, Double-dummy, Active Comparator-controlled, Multicenter Study to Assess the Efficacy and Safety of PGL4001 vs GnRH-agonist for Pre-operative Ttt of Symptomatic Uterine Myomas

Percentage of Subjects With Reduction of Uterine Bleeding at Week 13 Visit Defined as Pictorial Blood-loss Assessment Chart (PBAC) Score < 75 at End-of-treatment Visit (Week 13 Visit)

时间窗: 3 months

Uterine bleeding was assessed with the use of the PBAC, a validated self-reporting method to estimate menstrual blood loss. Patients recorded daily the number of tampons and towels used and the degree to which individual items were soiled with blood (plus small or large clots). Monthly scores range from 0 (amenorrhea) to more than 500, with higher numbers indicating more bleeding. A slightly stained tampon/towel scores 1, a partially stained tampon/towel scores 5, a completely saturated tampon scores 10 and a completely saturated towel scores 20. Small clots/flooding (2cm) score 1. Large clots/flooding (3cm) score 5. Menorrhagia is defined as a PBAC \> 100 during one menstrual period which approximates to a blood loss of \> 80 mL. A PBAC of 400 corresponds to a blood loss of around 300 mL or approximately 80 tampons/towels used. The week 13 PBAC score was calculated using the last 28 days of treatment.

Co-primary Safety Endpoint: Serum Estradiol Levels at End of Treatment Visit (Week 13 Visit) for PGL4001 Compared With GnRHagonist

时间窗: Week 13 visit

Measured by log 10 (log pg/ml) transformed values for estradiol (E2) in blood samples

Co-primary Safety Endpoint: % of Subjects Reporting Moderate or Severe Hot Flushes as Adverse Events Throughout the Treatment Period for PGL4001 Compared With GnRH-agonist

时间窗: Up to week 17

Difference in percentage of subjects reporting moderate or severe hot flushes: Frequency and severity of this adverse event(as spontaneously reported by patients or elicited by nonleading questions) were recorded on standard forms at every visit up to week 17.
