Discovery of Vilaprisan (BAY 1002670): A Highly Potent and Selective Progesterone Receptor Modulator Optimized for Gynecologic Therapies

Progesterone plays an important role in the female reproductive system. However, there is also evidence that gynecologic disorders/diseases such as uterine fibroids and endometriosis are progesterone-dependent. Steroidal and non-steroidal selective progesterone receptor modulators (SPRMs) have shown potential for the treatment of such diseases. Steroidal SPRMs, including mifepristone and ulipristal acetate, have proven effective in clinical trials. However, several steroidal SPRMs containing a dimethylamino substituent have been associated with elevated liver enzymes in patients. An earlier drug discovery program identified lonaprisan as a highly selective SPRM that did not show drug-related change in liver enzyme activity. Building on data obtained from that work, here we describe the research program that culminated in the discovery of a novel steroidal SPRM, vilaprisan, which combines an extremely high potency with very favorable drug metabolism and pharmacokinetic properties. Vilaprisan has entered clinical development and is currently undergoing phase 3 clinical trials.

Progesterone Receptor Antagonists

The invention relates to 17-hydroxy-17-pentafluoroethyl-estra-4,9(10)-dien-11-aryl derivatives of the formula I with a progesterone antagonising effect and processes for their preparation, their use for the treatment and/or prophylaxis of diseases, and also their use for producing medicaments for the treatment and/or prophylaxis of diseases, in particular of uterus fibroids (myomas, uterine leiomyomas), endometriosis, heavy menstrual bleeding, meningiomas, hormone-dependent breast cancers and troubles associated with the menopause or for monitoring fertility and emergency contraception.
