Primary Outcome Measures:
  • Annualized Pregnancy Rate (Pearl Index) For 91-Day Cycles by Cohort Using up to 14 Days Post-Last Combination Dose When Defining "On Drug" Pregnancy [ Time Frame: up to one year ]

    Pearl Index= ((100)*(number of pregnancies)*(4 cycles/year))/number of 91-day cycles completed.

    The pregnancy rate included "on-drug" pregnancies, defined as those pregnancies for which the date of conception was on or after the date of first dose of study medication, but no more than 14 days after the date of last combination dose of study medication.

    Pregnancy was defined as a positive pregnancy test verified by the study staff. The conception date was based on the ultrasound date. A pregnancy was not considered 'on drug' if conception clearly occurred prior to first dose of study medication, or more than 14 days after the date of last combination dose of study medication.

    Three denominators are reported;

    • excluding cycles where other birth control methods (BCMs) was used
    • all complete cycles
    • compliant-use (i.e. subject did not skip two or more consecutive pills or had a pattern of substantial non-compliance, or used a prohibited concomitant medication)

  • Annualized Pregnancy Rate (Pearl Index) For 91-Day Cycles by Cohort Using up to 7 Days Post-Last Combination Dose When Defining "On Drug" Pregnancy [ Time Frame: up to one year ]

    Pearl Index= ((100)*(number of pregnancies)*(4 cycles/year))/number of 91-day cycles completed.

    The pregnancy rate included "on-drug" pregnancies, defined as those pregnancies for which the date of conception was on or after the date of first dose of study medication, but no more than 7 days after the date of last combination dose of study medication.

    Pregnancy was defined as a positive pregnancy test verified by the study staff. The conception date was based on the ultrasound date. A pregnancy was not considered 'on drug' if conception clearly occurred prior to first dose of study medication, or more than 7 days after the date of last combination dose of study medication.

    Three denominators are reported;

    • excluding cycles where other birth control methods (BCMs) was used
    • all complete cycles
    • compliant-use (i.e. subject did not skip two or more consecutive pills or had a pattern of substantial non-compliance, or used a prohibited concomitant medication)


Secondary Outcome Measures:
  • Participants With Treatment-Emergent Adverse Events [ Time Frame: Day 1 up to one year ]
    Safety was assessed by summarizing adverse events recorded in the patient's daily diary and reported by subjects at each study visit, and by summarizing results of examination, vital signs and clinical laboratory values.

Primary Completion Date: June 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: DR-1011
Participants were instructed to take, by mouth, one tablet daily for four 91-day cycles.
Drug: DR-1011
Eighty-four orange, embossed tablets, each containing 100 μg levonorgestrel (LNG) / 20 μg ethinyl estradiol (EE) and 7 yellow, embossed tablets, each containing 10 μg of EE. One combination tablet was to be taken each day for 84 days followed by 7 days of EE tablets in 91-day cycles repeated consecutively for approximately one year (four 91-day cycles).
Other Name: levonorgestrel/ethinyl estradiol
