Patient case (clinical description): A 43-year-old woman, gravida 3 para 3, comes to the clinic complaining of recently painful menstrual cycles.  The patient's last menstrual period was 2 weeks ago. Urine β-hCG is negative. Menarche was at age 12, and menstrual periods occur every 28 days and lasts for 5 days.  She is sexually active with her husband and does not have pain with intercourse. BMI is 23 kg/m2 and Vital signs are normal.  On physical examination, the uterus is uniformly enlarged and tender. She is candidate for hysterectomy with the diagnosis of adenomyosis.

Patient's own account: I'm 43, and I paid a visit to my doctor because my last few periods were insanely painful. My last periods were 2 weeks ago. I already had three pregnancies that gave me the three lovely children. I did a urine test to check for potential pregnancy, and it came back negative. I started to have my periods at the age of 12, and I have been pretty regular with periods every 28 days for 5 days. I'm sexually active with my husband and I do not have any pain when we have sex. My BMI is 23 and my vitals were normal. The doctor performed a physical exam and found that my uterus was tender and enlarged. She proposed me a hysterectomy and diagnosed me with adenomyosis.

Eligibility criteria:
Inclusion Criteria:

          -  Male or female Caucasian participants aged 45-70 years;

             examination, 12-lead electrocardiogram (ECG), electroencephalogram (EEG), vital signs
             and clinical laboratory parameters (haematology, sedimentation rate, clotting,
             clinical chemistry, urinalysis and virus serology). Minor deviations of laboratory
             values and ECG parameters from the normal range may be accepted, if judged by the

             except surgically sterilized or at least 2 years postmenopausal) this was defined as
             follows: any form of hormonal contraception or intra-uterine device had to be used, at
             least from 4 weeks prior to the first dosing up to 4 weeks after the last dosing and
             an additional barrier contraception (condom or diaphragm) had to be used from 2 weeks
             prior to the first dosing up to 4 weeks after the last dosing;

          -  Negative blood beta-human chorionic gonadotropin (beta-HCG) test for females of
             childbearing potential determined at screening examination and prior to first dose
             administration in each period (the test is not necessary in females who are in
             post-menopausal state for at least 2 years or in females with status after surgical
             sterilisation).
