Design outcomes

Primary

MeasureTime frame
Main Objective: The primary objective of this study is to show superiority of vilaprisan in the treatment of heavy menstrual bleeding (HMB) in subjects with uterine fibroids compared to placebo;Secondary Objective: The secondary objectives of this study are to additionally evaluate the efficacy and safety of vilaprisan in subjects with uterine fibroids;Primary end point(s): Amenorrhea (yes/no), defined as menstrual blood loss (MBL) <2 mL during the last 28 days of treatment;Timepoint(s) of evaluation of this end point: The last 28 days of treatment period 1 and treatment period 2

Secondary

MeasureTime frame
Secondary end point(s): 1. HMB response defined as blood loss 50% reduction compared to baseline 2. Time to onset of amenorrhea. Onset of amenorrhea is defined by the first day for which the menstrual blood loss for all subsequent 28-day periods up to the end of the treatment period is <2 mL 3. Time to onset of controlled bleeding. Onset of controlled bleeding is defined by the first day for which the menstrual blood loss for all subsequent 28-day periods up to the end of the treatment period is <80.00 mL 4. Absence of bleeding (spotting allowed) during the last 28 days of the treatment; based on the UF-DBD 5. Endometrial histology (e.g. benign endometrium, presence or absence of hyperplasia or malignancy) 6. Endometrial thickness;Timepoint(s) of evaluation of this end point: 1. The last 28 days of treatment period 1 and treatment period 2 2. In treatment period 1and in treatment period 2 3. In treatment period 1 and in treatment period 2 4. The last 28 days of treatment period 1 and treatment period 2 5. Up to 36 weeks 6. Up to 36 weeks
