Asoprisnil ecamate (INN) (developmental code name J-956) is a synthetic, steroidal selective progesterone receptor modulator (SPRM) which was under development for the treatment of endometriosis, uterine fibroids, and menopausal symptoms but was discontinued. It is a potent and highly selective ligand of the progesterone receptor (PR) with mixed agonistic and antagonstic activity and much reduced antiglucocorticoid activity relative to mifepristone. The drug reached phase III clinical trials for the aforementioned indications prior to its discontinuation.
