Brief summary
The purpose of this study is to establish the bioequivalence of the hormones norgestimate, norelgestromin, and ethinyl estradiol in norgestimate/ethinyl estradiol (NGM/EE) tablets, formulated by wet process compared with the same hormones in NGM/EE tablets, formulated by dry process, in healthy women.
Detailed description
This is a Phase 1, single-dose, open-label (a medical research study in which participants and researchers are told which treatments the participants are receiving, unblinded), randomized (the study medication is assigned by chance), single-center and a 2-way crossover (method used to switch participants from one study group to another in a clinical trial) study in healthy women. The study consists of 3 parts: Screening phase, Treatment phase and end-of-study or withdrawal. Treatment periods will be separated by a wash out period of at least 10 days. The duration of participation in the study for an individual participant will be approximately 7 weeks. All participants will be randomly assigned in a 1:1 ratio to 1 of 2 possible treatment sequences and receive both of the following treatments: 1 oral tablet formulated by wet process or dry process, whereas each tablet contains norgestimate 250 microgram (mcg) and ethinyl estradiol 35 mcg. The primary endpoint of the study will be assessment of pharmacokinetic parameters. Participants' safety will be monitored throughout the study.
Interventions
Norgestimate /Ethinyl estradiol tablets (NGM/EE) containing norgestimate 250 mcg and ethinyl estradiol 35 mcg, formulated by wet process will be orally administered on Day 1 of Period 1 or Period 2.
Norgestimate /Ethinyl estradiol tablets (NGM/EE) containing norgestimate 250 mcg and ethinyl estradiol 35 mcg, formulated by dry process will be orally administered on Day 1 of Period 1 or Period 2.

| Maximum Plasma Concentration (C[max]) | Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2 | The C(max) is the maximum serum concentration which will be observed at the defined time points. |
| Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time (AUC [0-last]) | Pre-dose, 0.25, 0.5, 0.75, 1, 1.5, 2, 3, 5, 8, 12, 16, 24, 36, 48 and 72 hours after study drug administration on Day 1 of Period 1 and Period 2 | The AUC (last) is the area under the plasma concentration-time curve from time zero time of the last quantifiable concentration C(last), and C(last) is the last observed quantifiable concentration. |
