Why is this study being done?

The study drug is a new drug that is being developed for the treatment of endometriosis (a condition in which the tissue that behaves like the cells lining the uterus grows in other areas of the body) and uterine fibroids (noncancerous tumors that develop in the uterus). The study drug is very similar to a natural hormone that is made by brain cells. The study drug partially reduces the production of the female hormone estrogen in the ovaries.

The purpose of this study is to determine:

The primary objective of this study is to evaluate the safety, tolerability, and efficacy of elagolix, administered once daily or twice daily for 3 months in the management of moderate to severe endometriosis-associated pain, and to evaluate the effect of elagolix treatment on analgesic use for endometriosis-associated pain. Secondary efficacy objectives include assessment of persistence of efficacy at 6 months, and assessments of other endometriosis-related symptoms, analgesic use, as well as quality of life endpoints.
