Registered outcomes8
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Percentage of Participants With ≥3 Point Reduction in Peak Pelvic Pain Score and no Increase in Number of Ibuprofen Tablets Taken at Treatment Cycle 2, Compared to Baseline | Baseline 4-day cramping window and Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | Participants were asked to rate their worst pain or cramps in the past 24 hours on a scale of 0 to 10 (0=No pain or cramps to 10=Extreme pain or cramps) and to indicate the number of ibuprofen tablets they took during the 4-day cramping window. The peak pelvic pain score was to be calculated as the highest (daily) pelvic pain score observed within the cramping window of the cycle and the total number of ibuprofen tablets taken was to be based on the 4-day cramping window. The baseline peak pelvic pain score and number of ibuprofen tablets taken were to be defined as the mean value of the 2 peak pelvic pain scores and the mean value of the total number of ibuprofen tablets taken during the cramping window of each of the 2 menstruations during the screening period, respectively. The percentage of participants with a reduction in peak pelvic pain score of ≥3 points and no increase in the use of ibuprofen at Treatment Cycle 2 as compared to baseline was to be presented. |
| Primary | Number of Participants Who Experienced an Adverse Event (AE) | Up to approximately 126 days | An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study treatment, whether or not considered related to the use of study treatment. The number of participants who experienced an AE is presented. |
| Primary | Number of Participants Who Discontinued Study Treatment Due to an AE | Up to approximately 112 days | An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study treatment, whether or not considered related to the use of study treatment. The number of participants who discontinued study treatment due an AE is presented. |
| Secondary | Change From Baseline in Peak Pelvic Pain Score at Treatment Cycle 2 | Baseline 4-day cramping window and Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | Participants were asked to rate their worst pain or cramps in the past 24 hours on a scale of 0 to 10 (0=No pain or cramps to 10=Extreme pain or cramps). The peak pelvic pain score was to be calculated as the highest (daily) pelvic pain score observed within the 4-day cramping window of the cycle. The baseline peak pelvic pain score was to be defined as the mean value of the 2 peak pelvic pain scores during the cramping window of each of the 2 menstruations during the screening period. The change from baseline in peak pelvic pain score at Treatment Cycle 2 was to be presented. |
| Secondary | Change From Baseline in the Number of Days With no Impact on Items of Physical, Work/School and Social/Leisure Activities at Treatment Cycle 2 | Baseline 4-day cramping window and Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | Participants were asked to indicate how much pain or cramps limited their physical, work/school and social/leisure activities and over the previous 24 hours. The level of negative impact of dysmenorrhea on daily life was scored on a 5-point scale (0=Not at all to 4=Extremely impacted). For each of the 3 impact items, the baseline score was to be defined as the mean value obtained from the 2 menstruations during the screening period. The change from baseline to Treatment Cycle 2 in the number of days during the cramping window with no impact of dysmenorrhea (score = 0) on each of the following items was to be presented: work/school, physical activities and leisure/social activities. |
| Secondary | Percentage of Participants With Pelvic Pain Score of "0" or "1" and no Use of Ibuprofen Tablets at Treatment Cycle 2 | Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | Participants were asked to rate their worst pain or cramps on a scale of 0 to 10 (0=No pain or cramps to 10=Extreme pain or cramps) and to indicate the number of ibuprofen tablets they took during the 4-day cramping window. The percentage of participants with no or minimal pelvic pain (score of "0" or "1") and no use of ibuprofen at Treatment Cycle 2 was to be presented. |
| Secondary | Percentage of Participants With ≥3-point Reduction in Peak Pelvic Pain Score and a Decrease in Number of Ibuprofen Tablets Taken at Treatment Cycle 2, Compared to Baseline | Baseline 4-day cramping window and Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | Participants were asked to rate their worst pain or cramps in the past 24 hours on a scale of 0 to 10 (0=No pain or cramps to 10=Extreme pain or cramps) and to indicate the number of ibuprofen tablets they took during the 4-day cramping window. The baseline peak pelvic pain score and number of ibuprofen tablets taken were to be defined as the mean value of the 2 peak pelvic pain scores and the mean value of the total number of ibuprofen tablets taken during the cramping window of each of the 2 menstruations during the screening period, respectively. The percentage of participants with a reduction in peak pelvic pain score of ≥3 points and a decrease in the use of ibuprofen at Treatment Cycle 2 as compared to baseline was to be presented. |
| Secondary | Change From Baseline in the Mean Pelvic Pain Score at Treatment Cycle 2 | Baseline 4-day cramping window and Treatment Cycle 2 4-day cramping window, as determined by committee for each participant | The mean pelvic pain score was to be calculated as the mean of the highest scores for pelvic pain observed within the 4-day cramping window of the screening or treatment cycle. The baseline mean pelvic pain score was to be defined as the mean value of the 2 mean pelvic pain scores of the 2 menstruations during the screening period. The change from baseline in mean pelvic pain score at Treatment Cycle 2 was to be presented. |
