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)
EXPERIMENTALParticipants 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.
DRSP-EE
ACTIVE COMPARATORParticipants 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.
