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

IG-23-002

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

Subject is willing to collect daily first morning urines and store them until brought to the study site. 11. Lives within the study catchment area or a reasonable distance from the study site. 12. Understands and signs the IRB approved informed consent prior to undergoing any screening assessment. 13. Agrees not to participate in any other clinical trials during the course of this study. 14. Screening serum progesterone level greater than 3 ng/ml.- Exclusion Criteria: 1. Known hypersensitivity or contraindications to progestins. 2. Abnormal transvaginal ultrasound or safety laboratory results evaluated during the screening period recognized as clinically significant by the investigator or medically qualified designee. 3. Known or suspected alcohol or marijuana abuse. 4. Undiagnosed abnormal genital bleeding. 5. Undiagnosed vaginal discharge, lesions or abnormalities. 6. Women with a history of genital herpes can be included if the outbreaks are infrequent. Antiviral prophylaxis is allowed. 7. Uncontrolled Thyroid disorder. 8. Current use of hormonal contraception or a levonorgestrel releasing intrauterine device. 9.

Personal or family history of thrombophilia 17. History of retinal vascular lesions or partial or complete loss of vision. 18. Known or suspected carcinoma of the breast, endometrium, or other suspected progestin sensitive neoplasia. 19. History of other carcinomas excluding basal cell cancers unless in remission for \> 5 years. 20.

If the initial BP values are above these cut-offs, a total of 3 measurements may be taken and the results averaged. If the averaged BP is below the cut-off levels, the participant may be allowed into the study. Hypertension that is treated and controlled may be allowed based on the Investigator's discretion. 26. Clinically significant abnormal serum chemistry value based on the Investigator's judgement. 27.
