NCT03120728

Brief Summary

This study is enrolling healthy women ages 18-39yo who are not pregnant or breastfeeding, and are not using hormonal birth control. Initial screening visit will include a blood draw to assess if the participant has recently ovulated. If hormone test indicates ovulation occurred, participant will start the study 8 days after the start of their next menstrual period. On this study visit, vaginal ultrasound will be performed to look the ovaries for follicles. Vaginal ultrasound is then performed approximately every 2 days until the dominant follicle has grown into the size group assigned. When this occurs the participant will place the NuvaRing®, inside the vagina and blood will be drawn for hormone levels. Participant will then return daily the next 5 days (total of 6 daily visits) for vaginal ultrasound and blood draw to assess for signs of ovulation. After the 7th day the ring is in the vagina, the participant will remove the ring from her vagina at home. After removal, there will be twice weekly clinic visits for ultrasound and blood draw until menstrual bleeding occurs. At this point, participation in the study is complete. Participants are compensated for their time.

Outcome Measures

Primary Outcomes (1)

  • Percentage of ovulation suppression or dysfunction in relation to follicle size

    Describe the ability of the contraceptive vaginal ring to cause ovulation suppression or dysfunction when placed in the mid and advanced follicular phase. This will be determined via measurement of steroid hormones and assessment of the leading ovarian follicle for signs of rupture after placement of the contraceptive vaginal ring.

    The outcome is measured throughout the 6 week study.

Study Arms (3)

12-14mm leading follicle size

EXPERIMENTAL

Placement of the etonogestrel/ethinyl estradiol contraceptive vaginal ring when leading follicle measures 12-14mm on transvaginal ultrasound.

Drug: Etonogestrel/ethinyl estradiol contraceptive vaginal ring

15-17mm leading follicle size

EXPERIMENTAL

Placement of the etonogestrel/ethinyl estradiol contraceptive vaginal ring when leading follicle measures 15-17mm on transvaginal ultrasound.

Drug: Etonogestrel/ethinyl estradiol contraceptive vaginal ring

18mm or greater leading follicle size

EXPERIMENTAL

Placement of the etonogestrel/ethinyl estradiol contraceptive vaginal ring when leading follicle measures 18mm or greater on transvaginal ultrasound.

Drug: Etonogestrel/ethinyl estradiol contraceptive vaginal ring

Interventions

Placement of a contraceptive vaginal ring with subsequent assessment of ovulation disruption. Timing of placement depends on leading follicle size, as described in "Arms" section.
