Study Description

Brief Summary:

The purpose of this study is to evaluate the bleeding profile of norgestimate/ethinyl estradiol, an oral contraceptive tablet, given in an extended regimen

Condition or disease	Intervention/treatment	Phase
Metrorrhagia	Drug: Norgestimate/Ethinyl Estradiol tablet	Phase 2

Detailed Description:

This is an open-label study evaluating the bleeding profile of norgestimate/ethinyl estradiol tablets administered as an extended regimen (84 consecutive days of active tablets followed by seven days medication free) following a traditional regimen of two 28-day cycles (21 days of active tablets, followed by seven days of placebo tablets) of norgestimate/ethinyl estradiol tablets. All patients will receive norgestimate/ethinyl estradiol tablets in a traditional regimen for two 28-day cycles. Following the Traditional Treatment Phase, all patients will receive norgestimate/ethinyl estradiol tablets in an Extended Regimen Treatment Phase, consisting of 84 days of treatment with norgestimate/ethinyl estradiol tablets. Safety evaluations include physical examinations, adverse event reporting and vital signs. The hypothesis of the study is that a triphasic extended regimen would not result in breakthrough bleeding and spotting when the progestin dose drops. Traditional Regimen: two 28 day cycles of norgestimate 180 mcg daily for 1 week, 215 mcg daily for 1 week, 250 mcg daily for 1 week, placebo daily for 1 week. Extended Regimen: four uninterrupted cycles of norgestimate 180 mcg daily for 1 week, 215 mcg daily for 1 week, 250 mcg daily for 1 week, 1 week medication-free. In both Treatment Regimens patients receive ethinyl estradiol 25 mcg in each active tablet. The study is 147 days, Traditional days 1-56 and Extended days 57-147
