Drug: NOMAC-E2 COC
Registration Number

Lead Sponsor
Organon and Co
Brief Summary

The purpose of this study is evaluating Contraceptive Efficacy and Safety of NOMAC-E2 Combined Oral Contraceptive in Premenopausal Females Aged 14 to 35 Years (Inclusive).

Detailed Description

This is a Phase 3, Open-label, Multi-center, Single-arm Study to Assess Contraceptive Efficacy and Safety of the Nomegestrol Acetate + 17β-estradiol Combined Oral Contraceptive (OG-8175A) in Premenopausal Females Aged 14 to 35 Years (Inclusive). Potential participants must be sexually active and engage in heterosexual vaginal intercourse at least once per month with a partner who is not known to be subfertile, sterilized, or infertile, and should not routinely use any other form of contraception.

A total of 2,680 fertile premenopausal women aged 14 to 35 years (inclusive) will be screened to achieve about 1,878 (with at least 657 participants with BMI ≥30 kg/m2) being allocated to study treatment. Over 1,000 total participants are expected to complete 1 year of treatment (13 cycles).

The total duration of study participation will be up to 60 weeks, which includes a Pre-treatment Period of approximately 6 weeks, a Treatment Period of 52 weeks, and a Follow-up Period of 2 weeks after the last intake of study drug.

Arm && Interventions
GroupInterventionDescription
Nomegestrol Acetate + 17β-estradiol (NOMAC-E2; OG-8175A)NOMAC-E2 COCThe NOMAC-E2 COC active tablets contain 2.5 mg NOMAC and 1.5 mg E2 and will be used in a 24/4 regimen, i.e., 28-day cycles with 24 days of active tablet intake followed by 4 days of placebo tablet intake.
Primary Outcome Measures
NameTimeMethod
Number of on-treatment pregnancies per 100 women-years of at risk exposure1 year

The at-risk Pearl Index is defined as the number of on-treatment pregnancies (i.e., pregnancies from study drug start to 7 days after last intake of active study drug) divided by the number of 28-day cycles, either associated with a pregnancy or with both affirmed heterosexual vaginal intercourse and no use of additional contraception, with that number multiplied by 1300 to represent the number for 100 years of 13 cycles per year.

Secondary Outcome Measures
NameTimeMethod
Proportion of participants with an adverse event (regardless on potential relationship to study drug)1 year
Proportion of participants who prematurely discontinue study drug treatment1 year
Number of pregnancies during perfect use cycles per 100 women-years1 year

The perfect use Pearl Index is similar to the at-risk Pearl Index, but excludes subjects or select cycles per subject, from both the number of pregnancies and the number of cycles, where important deviations from the protocol have occurred. Important deviations for contraceptive cycles can include, but not be limited to, (a) non-compliance based on 4 missed active tablets during cycle, (b) non-compliance based on 2 consecutive missed active tablets during a cycle, (c) prohibited medications taken during the cycle. Important subject deviations for contraceptive analysis include, but not limited to, (a) \>75% of cycles where participant is non-compliant with study drug or not at risk for pregnancy, (b) participant is pregnant or without documented negative pregnancy on day of first study drug intake, (c) participant did not meet eligibility requires for absence of abnormal bleeding or breastfeeding.

Number of all on-treatment pregnancies per 100 years of exposure1 year

The typical-use Pearl Index is defined as the number of on-treatment pregnancies divided by the number of 28-day cycles, regardless of affirmed heterosexual vaginal intercourse or no use of additional contraception, with that number multiplied by 1300 to represent the number for 100 years of 13 cycles per year.

Number of pregnancies with participants placed in subgroups based on baseline BMI categories (<30 kg/m2, ≥30 kg/m2)1 year

Each of the three Pearl Index measures previously described will be evaluated separately for participant with body mass index values of \<30 kg/m2 and ≥ 30kg/m2, with the value as determined at the time of assignment to treatment.

By-cycle summary of bleeding-spotting28-day cycles across one year

For each cycle, the number of participants will be summarized according to the bleeding-spotting patterns (unscheduled bleeding-spotting, absence of scheduled bleeding-spotting, experienced no scheduled or unscheduled bleeding-spotting at all) observed during the cycle.

By-reference period summary of the bleeding and/or spotting days91-day reference periods across one year

For each 91-day reference period, the number of bleeding days, spotting days, and bleeding-spotting days will be summarized.

By-reference period summary of frequency of bleeding/spotting episodes91-day reference periods across one year

Bleeding/spotting patterns during the 91-day reference periods will be classified as no episodes, 1-2 episodes, 3-5 episodes, and \>5 episodes, where episodes are defined as one or more consecutive days during which bleeding or spotting occurred, bounded at each end by bleeding-spotting-free days.

By-reference period summary of subjects with prolonged bleeding spotting91-day reference periods across one year

Bleeding/spotting patterns during the 91-day reference periods will be classified as based on at least one bleeding/spotting starting with the reference period, where a length of \>7 days and of \>14 days will be evaluated.

NOMAC concentrations - relationship with body weightTreatment Week 5 and Treatment Week 17

NOMAC concentrations assessed through use of sparse sampling and population pharmacokinetic modeling to estimate the effect of body weight (kg).

NOMAC concentrations - relationship with BMITreatment Week 5 and Treatment Week 17

NOMAC concentrations assessed through use of sparse sampling and population pharmacokinetic modeling to estimate the effect of BMI (kg/m\^2).
