    Outcomes

    Primary Outcome Measures

    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
    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.
    Number of Participants Who Experienced an Adverse Event (AE)
    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.
    Number of Participants Who Discontinued Study Treatment Due to an AE
    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 Outcome Measures

    Change From Baseline in Peak Pelvic Pain Score at Treatment Cycle 2
    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.
    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
    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.
    Percentage of Participants With Pelvic Pain Score of "0" or "1" and no Use of Ibuprofen Tablets at Treatment Cycle 2
    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.
    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
    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.
    Change From Baseline in the Mean Pelvic Pain Score at Treatment Cycle 2
    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.

    5. Study Description

    Brief Summary
    The purpose of this study was to evaluate the efficacy of the etonogestrel (ENG) + 17β-estradiol (E2) (MK-8342B) vaginal ring compared to placebo vaginal ring in the treatment of dysmenorrhea at Treatment Cycle 2. This study was also to assess the safety and tolerability of the ENG-E2 vaginal rings over 4 treatment cycles. Primary hypothesis: Relative to the placebo ring, the ENG-E2 vaginal ring results in a greater proportion of participants with a ≥3-point reduction in peak pelvic pain score and no increase in the number of rescue pain relief (ibuprofen) tablets taken at Treatment Cycle 2 as compared to baseline.
    Detailed Description
    The cramping window for each participant was to be defined as a 4-day time interval that began the day prior to initiation of each cyclic bleeding episode (spontaneous menses or hormone withdrawal bleeding) and continued until the third bleeding day (inclusive). An external committee of blinded independent reviewers was to determine the 4-day cramping window for each participant so that analysis of the efficacy data could be conducted. The study was terminated early due to a business decision by the Sponsor to discontinue product development for reasons unrelated to safety or efficacy outcomes. Due to the early study termination, the blinded independent review committee that was supposed to determine the 4-day cramping windows for data analysis was not assembled; thus cramping windows were not determined. Without defined cramping windows, the efficacy outcome measures for this study could not be analyzed.
