  • Investigator: Michael Thomas
  • Specialties:
  • Type of Study: Drug

The purpose of this study is to find out: • If there are any effects of the study pill on menstrual periods, ovulation (releasing an egg from the ovary), preventing pregnancies and bleeding; • How safe the study pill is to use every day; • How much SPRM (selective progesterone receptor modulator), estrogen-free hormone needs to be in the study pill to make sure that it prevents pregnancy; • How the hormone in the study pill affects your rate of ovulation (how often you release an egg); • How the hormone in the study pill is absorbed by the body; • Whether the study drug in the study pill affects your everyday life and if it causes any side effects different from what we know about side effects from other contraceptives; if the side-effects from this study pill are more or less serious than the side-effects from other hormonal contraceptives. The study pill used in this study is investigational and is being developed as a possible new method of birth control. The study pill is made of ulipristal acetate, an estrogen-free hormonal contraceptive that contains a selective progesterone-receptor modulator (SPRM). A SPRM is a hormone that may block the action of the hormone progesterone. The oral pill releases the hormone into your body. The hormone is intended to keep women from releasing an egg so they do not get pregnant. Other birth control pills work the same way.
