Brief Summary

This clinical trial determines if an oral medication taken within 2 days of anticipated ovulation will delay ovulation by 7 days. The study compares oral placebo tablets (control) to oral levonorgestrel, a synthetic hormone, and meloxicam, a non-steroidal anti-inflammatory drug (treatment) in 21 healthy women between the ages of 18 to 40. The control or treatment are taken 48 hours apart in the first and second menstrual cycle, respectively. The first dose is taken when the ovarian follicle has a diameter of 17 mm measured by transvaginal ultrasound. This follicle diameter is found 2 ± 1.0 days before ovulation. Ovulation is determined by a change in urinary hormone levels analyzed in first morning daily urine. The Investigators anticipate that the control cycle will have an interval to ovulation of ≤ 3 days from first placebo to ovulation while a delay of ≥7 days is found between first treatment to ovulation. A second question is to determine the side effects between control versus treatment based on symptoms such as nausea or abdominal cramping, change in blood pressure or pulse rate and the interval in menstrual bleeding. Each study participant has approximately 9 visits during each of two menstrual cycles. The visits between menstrual day 9 (first visit) to largest follicle are 3 to 6 depending upon follicle growth. A blood sample with a transvaginal ultrasound for ovarian follicle diameter is obtained at each visit. The appropriate medication is taken when the ovarian follicle largest diameter is 17 mm. The second dose is taken 2 days later with interim and final visits at 5 and 10 days following first dose. Each participant collects first morning urine from menstrual day 9 to 23. A teaspoonful of morning urine is placed in a storage tube and kept in a refrigerator freezer section until returned at a scheduled visit. All urine samples are kept frozen until analyzed for the metabolites of estrogen and progesterone by a central research laboratory. A change in the ratio of estrogen to progesterone metabolites is indicative of ovulation because more progesterone is secreted after ovulation from the ovary. The primary research outcome compares the interval in days from first dose of medication to ovulation between control and treatment. Secondary outcomes are menstrual cramps, vaginal bleeding, nausea, and headache, and changes in blood pressure, pulse, and interval between menstrual periods in control compared to treatment cycles.

Outcome Measures

Primary Outcomes (1)

• Interval to ovulation in normal women following placebo is 3 days compared to 7 days following levonorgestrel plus meloxicam

  Number of days from first dose of medication to evidence of ovulation

  The outcome will be assessed at the end of the first and second menstrual cycle of 28 ± 2.0 Days, respectively in up to two menstrual cycles.

Secondary Outcomes (1)

• Safety using Blood pressure

  Changes in the mean sitting blood pressure during the placebo and intervention menstrual cycles. Sitting blood pressures are measured from menstrual day 9 to 23 in each menstrual cycle in up to 2 menstrual cycles.

Other Outcomes (2)

• Change in menstrual bleeding interval or unscheduled bleeding compared between interventions

  Unscheduled bleeding or delay in menses is measured from menstrual day 1 to end of cycle in placebo compared to intervention cycle with each cycle 28 ± 2.0 days. Measurement are made in up to two menstrual cycles.

• Compare adverse events between treatments

  Events are measured from day 1 to end of cycle in placebo compared to intervention cycle with each cycle 28 ± 2.0 days. Measurement are made in up to two menstrual cycles.

Study Arms (2)

Study Design

• Study Type: interventional
• Phase: phase 2
• Allocation: RANDOMIZED
• Masking: SINGLE
• Who Masked: OUTCOMES ASSESSOR
• Masking Details: This open label study will be masked by not allowing the analysis of the urine samples collected for determining the day of the follicular luteal transition (ovulation) to be known to the laboratory director and technicians.
• Purpose: TREATMENT
• Intervention Model: SEQUENTIAL
• Sponsor Type: OTHER
• Responsible Party: PRINCIPAL INVESTIGATOR
• PI Title: Chief Executive Officer

Model Details: 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). An "n" of 21 was calculated using the Log-Rank Test method and setting the Power to 80% and alpha to 0.05 to test the hypothesis that there was no difference between the "survival curves" for the placebo and drug-treated cycles.
