Approximately 1,600 post-menarche women aged 14 to 45 years who are candidates for systemic hormonal contraception are expected to be enrolled. All participants will receive the investigational product, consisting of N0999 administered in a 24+4 regimen. Each treatment cycle consists of 24 active tablets followed by 4 inactive tablets. Participants will receive treatment for 13 consecutive 28-day cycles, corresponding to approximately 52 weeks of treatment. Total study participation, including screening and follow-up, is expected to be approximately 58 weeks.

Secondary objectives include assessing the Pearl Index in the overall study population and in participants older than 35 years, evaluating the method-failure Pearl Index based on correct and consistent use, and estimating cumulative pregnancy rates using Life Table Analysis. Additional objectives include evaluating cycle control, including withdrawal bleeding, intermenstrual spotting, amenorrhea, and bleeding duration, as well as participant satisfaction with study treatment.
