ListOutcomeTime frameDescription
PrimaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in the Number of Days With Dysmenorrheic Painbaseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Dysmenorrheic pain was defined as pelvic pain during the menstrual/withdrawal bleeding episode and the 2 days before this episode. Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in the Sum of Score Points of Dysmenorrheic Painbaseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Dysmenorrheic pain: pelvic pain during menstrual/withdrawal bleeding (WB) episode and 2 days before. Scores per day: 0 No pain; 1 Mild pain with no need for painkiller; 2 Moderate pain with need for painkiller; 3 Severe pain with need for painkiller. Baseline period: 2 days before 1st menstrual bleeding until 3rd day before 3rd menstrual bleeding (normalized to standard 56-day period). Treatment period: 2 days before WB of 1st treatment cycle until 3rd day before WB of the cycle after 2nd treatment cycle (normalized to standard 56-day period). Score difference min -168 (best), max 168 (worst)
SecondaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in Number of Days With Pelvic Pain Independent of Occurrence of Vaginal Bleedingbaseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in Number of Days With Pelvic Pain During Unscheduled Bleedingbaseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Evaluated was the number of days with bleeding-associated pelvic pain, excluding days during withdrawal bleeding (WB) and the 2 days preceding such WB, and during administration deviation bleeding and the 2 days preceding such bleeding (normalized to a standard 56-day period). Baseline period: 2 days before first menstrual bleeding until 3rd day before 3rd menstrual bleeding (normalized to standard 56-day period). Treatment period: 2 days before WB of the 1st treatment cycle until 3rd day before the WB of the cycle after the 2nd treatment cycle (normalized to standard 56-day period).
SecondaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in Rescue Medication Use (Only Bleeding Episodes Used Including the Two Days Before the Episode)baseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Rescue medication use was standardized intake of 200 mg Ibuprofen tablets. Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryChange Between Baseline Evaluation Period and Treatment Evaluation Period in Rescue Medication Use (Entire Evaluation Period Used)baseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Rescue medication use was standardized intake of 200 mg Ibuprofen tablets. Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryPercentage of Participants With Interference of Dysmenorrheic Pain With Work/School and Social or Other Activity (Only Bleeding Episodes Used Including the Two Days Before)baseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Interference of dysmenorrheic pain with work/school and social or other activity was assessed (yes/no). Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryPercentage of Participants With Interference of Dysmenorrheic Pain With Work/School and Social or Other Activity (Entire Evaluation Period Used)baseline period (2 baseline cycles, usually 56 days) vs. treatment period (on-treatment cycles 2 and 3, usually 56 days)
Interference of dysmenorrheic pain with work/school and social or other activity was assessed (yes/no). Baseline period: 2 days before the first menstrual bleeding until 3rd day before the 3rd menstrual bleeding (normalized to a standard 56-day period). Treatment period: 2 days before the withdrawal bleeding (WB) of the 1st evaluable treatment cycle until 3rd day before the WB of the cycle after the 2nd evaluable treatment cycle (normalized to a standard 56-day period).
SecondaryPercentage of Participants Satisfied With Study TreatmentFrom cycle 1 to cycle 3 (28 days per cycle)Participants were asked to express the degree of their satisfaction with study treatment.
SecondaryNumber of Days With Bleeding or SpottingFrom day 1 to day 90
Bleeding/spotting episodes (day\[s\] with bleeding/spotting preceded and followed by at least 2 bleeding/spotting-free days) were described using the reference period (RP) method (length of RP: 90 days) recommended by the World Health Organization. 1st RP started on the 1st day of study medication. The total number of days during bleeding or spotting episodes was counted. Spotting = less than associated with normal menstruation relative to the subject's experience with no need for sanitary protection (except for panty liners). Bleeding = any bleeding of greater intensity than spotting.
