Summary

The purpose of this study is to assess the etonogestrel (ENG) + 17β-estradiol (E2) vaginal ring's efficacy compared to a placebo vaginal ring in the treatment of dysmenorrhea at Treatment Cycle 2. In addition, this study will assess the safety and tolerability of the ENG-E2 vaginal rings. 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.

Conditions

  • Moderate to Severe Primary Dysmenorrhea

Interventions

DRUG

Etonogestrel (ENG) 125 μg + 17β-estradiol (E2) 300 μg vaginal ring

Up to 4 cycles (or 6 cycles if also participating in the extension) of ENG-E2 125 μg/300 μg administered intravaginally. Each cycle will consist of 21 days of vaginal ring use followed by 7 ring-free days.

DRUG

Placebo vaginal ring

Up to 4 cycles (or 6 cycles if also participating in the extension) of placebo administered intravaginally. Each cycle will consist of 21 days of placebo vaginal ring use followed by 7 ring-free days.

DRUG

Ibuprofen

Ibuprofen tablets, to be taken orally, will be provided for use as rescue medication for dysmenorrhea treatment throughout the study.
