Outcome Measures

Primary Outcomes (1)

  • Pearl Index, by Treatment Group

    Primary Efficacy Outcome measure for this study was contraceptive efficacy, or the prevention of in-treatment pregnancy. The total incidence of in-treatment pregnancies was expressed as the Pearl Index, which is defined as the number of in-treatment pregnancies per 100 woman-years of exposure (one woman-year defined as a period of 365.25 days).

    Up to 1 year

Secondary Outcomes (2)

  • Percentage of Participants With Intermenstrual (Breakthrough) Bleeding/Spotting, by Cycle

    Up to 1 year

  • Percentage of Participants With Absence of Withdrawal Bleeding, by Cycle

    Up to 1 year

Study Arms (2)

ENG-EE (NuvaRing)

EXPERIMENTAL

Participants were to complete 13 cycles of etonogestrel (ENG) and ethinylestradiol (EE) use. Each cycle was 28 days, with a 21-day active treatment period followed by a 7-day ring-free period. Participants used one ring per cycle. Each ring contained 11.7 mg ENG and 2.7 mg EE, and released on average 120 mcg/day of ENG and 15 mcg/day of EE.

Drug: ENG 120 µg + EE 15 µg intravaginal ring

DRSP-EE

ACTIVE COMPARATOR

Participants were to complete 13 cycles of drospirenone (DRSP) and ethinylestradiol (EE) use. Each cycle was 28 days, with a 21-day active treatment period followed by a 7-day tablet-free period. Participants received a total of 21 tablets of DRSP-EE per cycle. Each tablet contained 3 mg DRSP and 30 μg EE.

Drug: DRSP 3 mg + EE 30 µg

Interventions

13 cycles of ENG-EE (NuvaRing) vaginal ring use. Each cycle 28 days, with a 21-day active treatment period followed by 7-day ring-free period. One ring per cycle, each ring containing 11.7 mg ENG and 2.7 mg EE, and releasing on average 120 mcg/day of ENG and 15 mcg/day of EE.

ENG-EE (NuvaRing)

13 cycles of DRSP-EE tablet use. Each cycle 28 days, with a 21-day active treatment period followed by a 7-day tablet-free period. Participants received total of 21 tablets per cycle, each tablet contained 3 mg DRSP and 30 μg EE.
