Brief summary

This is an open-label, single-treatment study. All subjects will receive 12 months of oral contraceptive therapy with DR-103. Study participants will receive physical and gynecological exams, including Pap smear. During the study, all participants will be required to complete a diary.

Interventions

DRUGDR-103

One tablet daily. Four 91-day cycles of the DR-103 regimen: 42 days combination therapy of 20 mcg ethinyl estradiol (EE) /150 mcg levonorgestrel (LNG) followed by; 21 days combination therapy of 25 mcg EE/150 mcg LNG followed by; 21 days combination therapy of 30 mcg EE/150 mcg LNG followed by; 7 days of 10 mcg EE.

MeasureTime frameDescription
Summary of Participants With Treatment-emergent Adverse EventsDay 1 up to 13 monthsThe on-treatment time frame spanned the time during which study drug was administered until 3 weeks beyond the last study drug date. Relationship to study drug was assessed by the investigator. Serious AEs (SAEs) are those that resulted in death, were life-threatening, required or prolonged inpatient hospitalization, resulted in persistent or significant disability/incapacity, congenital anomaly, or resulted in an important medical event that may have jeopardized the patient or required medical or surgical intervention.
Typical-Use Pregnancy Rates Based on Pearl Index (PI) Analyses for 28-Day Cycle-Equivalents and Broken Out by Subpopulations Defined by Participant WeightDay 1 up to year 1Contraceptive failure is measured by the pregnancy rate calculated using the Pearl Index (PI). PI used all pregnancies, as determined by a positive urine and/or serum pregnancy test, except those for which the date of conception was before starting DR-103 or \> 7 days after stopping the combination EE/LNG treatment of DR-103. The estimated date of conception and gestational age of the fetus was determined by transvaginal or abdominal ultrasound. In order to compare the efficacy of extended treatment with DR-103 to conventional 28-day cyclic oral contraceptive treatment, the 91-day DR-103 treatment cycle was separated into three 28-day cycle-equivalents, derived from the 84-day active combination (EE/LNG) pill period of each 91-day extended cycle. The PI is defined as number of contraceptive failures per 100 women-years of exposure: (100)\*(total number of pregnancies)\*(13)/(total number of 28-day cycles)
