Clinical Trial 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.


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Change From Baseline in Mean Menstrual Cramping Pain Score Through 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). Baseline and Day 29 to 56 (Cycle 2)
Secondary Change From Baseline in Total Mean Impact Score Through 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). Baseline and Day 29 to 56 (Cycle 2)
Secondary Change From Baseline in Number of Ibuprofen Tablets Taken Through 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. Baseline and Day 29 to 56 (Cycle 2)
Secondary Change From Baseline in Number of Days of Ibuprofen Intake Through 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. Baseline and Day 29 to 56 (Cycle 2)
