Brief 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:

• 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

Outcome Measures

Primary Outcomes (1)

• Interval from first dose to evidence of ovulation.

  An ovarian follicle diameter of 17 mm is used to take the first dose of medication. Daily morning urine samples are analyzed for estrone-3-glucronide and pregnanediol-3-glucuronide. Changes in the ratio of these two metabolites is indicative of ovulation termed the follicular luteal shift. The interval from first dose to follicular luteal shift is estimated to be 3 days. The active treatment will be given when the ovarian follicle diameter is also 17 mm. The outcome is estimated to be a delay of 7+ days from 1st dose to the follicular luteal shift or ovulation

  The interval is estimated to be 3 days from first dose to evidence of ovulation with placebo and 7 days following active treatment.

Secondary Outcomes (2)

• Change in blood pressure

  The blood pressure is monitored at screening and from menstrual day 9 to 24 in each of two treatment cycles.

• Change in Pulse

  Pulse rate is measured at all visits throughout the study

Other Outcomes (1)

• Unscheduled endometrial bleeding and changes in interval, amount and duration of menstrual bleeding.

  Daily diary cards will be kept by each participant beginning menstrual day 9 of first cycle. Diary cards will be returned at the exit visit within two weeks of the final (second) menstrual period.

Study Arms (2)

Placebo

PLACEBO COMPARATOR

The placebo is calcium carbonate 750 milligram (mg) known as TUMS. Each participant will take one tablet orally and repeat 48 hours later.

Other: calcium carbonate 750 milligram

Levonorgestrel plus meloxicam

ACTIVE COMPARATOR

The active comparator is levonorgestrel 1.5 milligram (mg) and meloxicam 15 milligram (mg) taken together orally and repeated 48 hours later.

Drug: Levonorgestrel 0.15 milligram; Drug: Meloxicam 15 milligram

Interventions

Levonorgestrel 0.15 milligram DRUG

The study design is an open label randomized single blind clinical trial in which each participant will receive placebo two tablets 48 hours apart in their first menstrual cycle and then levonorgestrel plus meloxicam 48 hours apart in their subsequent menstrual cycle. We will compare the interval from taking the first dose of medication to the development of a functioning corpus luteum based on the shift in the ratio of urinary estrone-3-glucuronide(EC) / pregnanediol-3-glucuronide (PDG).

Also known as: Plan B one Step

Levonorgestrel plus meloxicam

Meloxicam 15 milligram DRUG

The study design is an open label randomized single blind clinical trial in which each participant will receive placebo two tablets 48 hours apart in their first menstrual cycle and then levonorgestrel plus meloxicam 48 hours apart in their subsequent menstrual cycle. We will compare the interval from taking the first dose of medication to the development of a functioning corpus luteum based on the shift in the ratio of urinary estrone-3-glucuronide(EC) / pregnanediol-3-glucuronide (PDG).
