Description
Inclusion Criteria:
- Patients 18 years and older and premenopausal (based on gynecological history i.e. still menstruating; no significant estrogen deficiency symptoms)
- Diagnosis of uterine fibroids documented by ultrasound and relevant symptoms reported by the patient (e.g. heavy menstrual bleeding, pelvic pressure)
- Patients for whom surgery (hysterectomy or myomectomy) for the treatment of symptomatic uterine fibroids is planned
- Patients who are otherwise healthy as shown by medical history, physical and gynecological examinations, and laboratory test results
Exclusion Criteria:
- Contraindications for the progesterone receptor modulators (PRM) vilaprisan or ulipristal acetate
- Use of medication that might interfere with the conduct of the study or the interpretation of the results (e.g. continuing use of hormonal contraceptives, tranexamic acid or other treatments for heavy menstrual bleeding, progesterone receptor modulators, gonadotropin-releasing hormone agonist, anticoagulants, moderate and strong CYP3A4 inducers and moderate and strong CYP3A4 inhibitors within a defined time period before treatment starts.

Primary Outcome Measures
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
The expression level of biomarker for glandular and stromal cell proliferation (Ki-67) in the endometrium of the same patient before treatment and when treated with VPR (vilaprisan) prior to surgery
Time Frame: From pre-treatment biopsy to post-treatment biopsy_ Up to 20 weeks
|
Pre-treatment biopsy: The endometrial biopsy will be performed between Day 6 to 13 of the menstrual cycle that occurs after the screening visit and before treatment commences.
Post-treatment biopsy as second endometrial biopsy is taken (if possible within 24 hours) after end of VPR treatment.
|
From pre-treatment biopsy to post-treatment biopsy_ Up to 20 weeks
|
|
The expression level of biomarker for myoma cell proliferation (Ki-67) in fibroid tissue of patients not treated with PRM (progesterone receptor modulator )and those who have been treated with VPR prior to surgery
Time Frame: After maximum 12 weeks of treatment
|
Fibroid tissue sample will be collected from the uterus following surgery (if possible within 24 hours) after end of VPR treatment
|
After maximum 12 weeks of treatment
|
|
The expression level of biomarkers for apoptotic regulation in the endometrium (BCL-2 (B-cell lymphoma 2), caspase 3) of the same patient before treatment and when treated with VPR prior to surgery
Time Frame: From pre-treatment biopsy to post-treatment biopsy_ Up to 20 weeks
|
Pre-treatment biopsy: The endometrial biopsy will be performed between Day 6 to 13 of the menstrual cycle that occurs after the screening visit and before treatment commences.

Time Frame: From pre-treatment biopsy to post-treatment biopsy_ Up to 20 weeks
|
Pre-treatment biopsy: The endometrial biopsy will be performed between Day 6 to 13 of the menstrual cycle that occurs after the screening visit and before treatment commences.
