Dysmenorrhea
Conditions
Brief summary
The study investigates four vaginal ring groups with respect to relief of primary dysmenorrhea, and should identify at least one vaginal ring that shows clinically relevant treatment efficacy in relief of primary dysmenorrhea.
Detailed description
The study investigates four vaginal ring groups with respect to relief of primary dysmenorrhea, and should identify at least one vaginal ring that shows clinically relevant treatment efficacy in relief of primary dysmenorrhea. The intake of ibuprofen rescue medication and the impact on daily life is investigated: change from baseline data of these two variables will be compared between each of the four active ring groups, separately, and the placebo ring group. Furthermore, the study assesses the measurement characteristics and psychometric properties of a newly developed Dysmenorrhea Daily Dairy. Vaginal bleeding pattern and general safety and tolerability will also be evaluated.
Interventions
Either 700 or 900 mcg NOMAC and 300 mcg E2 intravaginal ring for two 28-day cycles
Either 100 or 125 mcg ENG and 300 mcg E2, intravaginally for two 28-day cycles
Placebo to match vaginal ring, intravaginally for two 28-day cycles
Ibuprofen 400 mg will be dispensed throughout the entire study as needed as rescue medication for treating menstrual cramping pain. The maximum daily ibuprofen dose is 3200 mg (8 tablets)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change From Baseline in Mean Menstrual Cramping Pain Score Through Cycle 2 | Baseline and Day 29 to 56 (Cycle 2) | The Mean Menstrual Cramping Pain score was calculated as the average of the three highest daily menstrual cramping scores (item #3 of the Menstrual Distress Questionnaire: Cramps) in the baseline cycle and treatment Cycle 2, respectively. The daily menstrual cramping pain score was based on five pain categories: none (0); mild (1); moderate (2); strong (3); and severe (4). In case of absence of withdrawal bleeding, or onset of menstruation, the mean of the three highest menstrual cramping pain scores recorded within Days 21-28 was used for analysis. The Mean Menstrual Cramping Pain Score in the baseline or subsequent cycles could range from 0 (none) to 4 (severe). |

| Change From Baseline in Total Mean Impact Score Through Cycle 2 | Baseline and Day 29 to 56 (Cycle 2) | Total Mean Impact Score is the mean of the sum of the daily responses to questions 6, 8, 9, and 10 in the Dysmenorrhea Daily e-Dairy, as recorded within the menstrual cramping pain analysis window. These questions assessed how much interference there was from pelvic cramping pain on work/school activities (Q6), physical activities (Q8), social/leisure activities (Q9) and sleep (Q10). Each question was rated on a 5-point (0-4) scale, with 0 being not at all, 1 slightly, 2 moderately, 3 quite a bit and 4 extremely. The total mean impact score could thus range from 0 (lowest possible impact) to 16 (highest possible impact). |
| Change From Baseline in Number of Ibuprofen Tablets Taken Through Cycle 2 | Baseline and Day 29 to 56 (Cycle 2) | Participants were provided with ibuprofen 400 mg tablets at the screening visit to be taken throughout the study as needed as rescue medication for treating menstrual cramping pain. The maximum daily ibuprofen dose was 3200 mg (8 tablets). Participants were instructed to take the provided ibuprofen, and no other medications, for the relief of menstrual cramping pain, and to record their ibuprofen usage in their e-Diaries. |
