A Phase II Study to Evaluate the Delay in Ovulation Following Oral Levonorgestrel Plus Meloxicam Compared to Placebo in Obese But Normal Menstruating Women

Summary

The goal of this clinical trial is to compare the delay in ovulation between placebo to levonorgestrel plus meloxicam in obese women with normal menses. The main questions it aims to answer are: 1. Ovulation will be delayed by ≥7 days following the first dose of levonorgestrel plus meloxicam compared to ovulation within 3 days following the first dose of placebo. 2. There will be no difference in unscheduled vaginal bleeding or adverse events between the two treatments \[placebo versus levonorgestrel plus meloxicam\]. Participants will: * undergo two treatment cycles the 1st uses placebo and the 2nd is levonorgestrel plus meloxicam, * maintain daily diary logs for adverse events, unscheduled bleeding, and onset, cessation, and amount of menstrual bleeding, * collect daily first morning voided urine from menstrual day 9 to 24, * undergo transvaginal ultrasound for ovarian follicle development on menstrual days 9, 11,13 and 14. * allow a blood sample to be drawn on days with ultrasound scans. * Take 1st placebo and levonorgestrel plus meloxicam under observation when dominant ovarian follicle is 17 ±1.0 millimeters (mm) in diameter and 2nd dose 48 hours later. Researchers will compare the placebo cycle to levonorgestrel plus meloxicam to see if ovulation is delayed, there is unscheduled vaginal bleeding, menstrual onset is delayed or there is an abnormal amount or duration of menses, there is any difference in treatment emergent side effects and any change in vital signs
