About Endometriosis
Endometriosis affects an estimated 1 in 10 women during their reproductive years, which is approximately 176 million women in the world. (1) Endometriosis is a disease in which tissue similar to the lining inside the uterus (called "the endometrium") is found outside the uterus, where it induces a chronic inflammatory reaction that may result in scar tissue. It is primarily found on the pelvic peritoneum, on the ovaries, in the rectovaginal septum, on the bladder, and bowel. (2) The symptoms of endometriosis include painful periods, painful ovulation, pain during or after sexual intercourse, heavy bleeding, chronic pelvic pain, fatigue and infertility, and can impact on general physical, mental, and social well-being. (3) The World Endometriosis Research Foundation (WERF) EndoCost study, the first ever prospective study of the actual cost of endometriosis, estimated the annual cost of endometriosis at EUR 70.9 billion in the US and EUR 58.8 billion in Germany, UK, France and Italy.

About KLH-2109/OBE2109 and GnRH
KLH-2109/OBE2109 prevents the endogenous gonadotropin releasing hormone (GnRH) from activating its pituitary receptors which ultimately reduces estrogen production by the ovaries. KLH-2109 has a potentially best-in-class profile that allows partial estrogen suppression. It maintains estradiol in the low-normal range, providing symptom reduction while avoiding significant bone loss or other adverse effects that can be associated with excessive suppression of estrogen. Phase 2a studies in Japan indicate that KLH-2109 induces a dose-dependent reduction in serum LH and estradiol, resulting in a reduction of endometriosis-associated pain and bleeding days. A Phase 2b study of OBE2109 versus Placebo in endometriosis is scheduled to start mid-2016.
