Harris HA, Bruner-Tran KL, Zhang X, Osteen KG, Lyttle CR. A selective estrogen receptor-beta agonist causes lesion regression in an experimentally induced model of endometriosis. Human reproduction (Oxford, England). 2005 Apr;20(20). 936-41. PMID: 15618247 [PubMed]
Endometriosis is a common gynaecological problem of uncertain aetiology. It affects primarily young, reproductive-aged women and can result in chronic pelvic pain and infertility. Current approved therapies have significant side-effects and hysterectomy is employed as a final solution. ERB-041 is a selective estrogen receptor-beta (ERbeta) agonist that has anti-inflammatory activity in preclinical models of arthritis and inflammatory bowel disease, but is inactive in many preclinical models of classic estrogen activity. Because endometriosis is now thought to be, at least in part, an inflammatory disease, we evaluated ERB-041's activity in an experimentally induced model of endometriosis.
