Comparative study of BAY86-5300 with a flexible extended regimen for dysmenorrhea

Trial purpose

The is a multi-center, randomized, open-label, active-controlled, parallel-group comparative study (24-week treatment period).
The objective of this study is to prove the superiority of BAY 86-5300 with flexible extended regimen for treatment of dysmenorrhea to BAY 86-5300 with 28-day cyclic regimen in terms of primary efficacy variable, number of days with dysmenorrheic pain over 140 days of evaluation period.
In addition, the long-term safety of the flexible extended regimen of BAY86-5300 in patients treated for one year will be investigated.

Key Participants Requirements

Sex

Female

Age

20 - N/A
  • - Dysmenorrhea patients with a total dysmenorrhea score (sum of the two sub-scores: severity of dysmenorrhea and use of analgesics) of at least 3 points in each of the last two menstruations before randomization (baseline observation phase)
    - Patients with dysmenorrheic pain during the 2 baseline cycles before randomization. Dysmenorrheic pain means any spasmodic pelvic pain or lower abdominal pain with possible radiation towards back or thighs recorded in the Patient Diary in correspondence with a withdrawal and/or menstrual bleeding episode. Pain could start up to 2 days before the onset of the bleeding episode the bleeding and terminates on the last day of bleeding of before
    - Patients having the regular cyclic menstrual period (25 to 38 days) in the latest two menses before randomization (baseline observation phase)
    - Willingness to use a barrier method (i.e., non-hormonal method) for contraception during the study. Acceptable methods of contraception include (i) condoms (male or female) with or without a spermicidal agent; (ii) diaphragm or cervical cap with spermicide; (iii) intra-uterine device.
  • - Patients who have organic diseases of which surgical treatment is prioritized by the investigator
    - Patients aged 40 years or older with ovarian chocolate cysts being more than 10 cm in size of the longest diameters
    - Patients with ovarian chocolate cysts having solid part in the cyst
