Conditions:

Mibolerone is a synthetic anabolic steroid. It binds both androgen and progesterone receptors and exerts both androgenic and progestagenic actions. Mibolerone (CHEQUE® Drops) was used in veterinary for estrous (heat) prevention in adult female dogs not intended primarily for breeding purposes. No prescription preparation, human or veterinary, is currently known to contain mibolerone worldwide.

Vilaprisan, a small molecule progesterone receptor antagonist is being developed by Bayer HealthCare Pharmaceuticals (formerly Bayer Schering Pharma) for the treatment of endometriosis and uterine leiomyoma. Hormonal imbalance observed in women with endometriosis is a potential target for treating endometriosis. Vilaprisan is a highly selective steroidal progesterone receptor modulator (SPRM). It is a partial agonist of progesterone receptor, which means that the drug activates progesterone receptors to a certain degree upon binding. This triggers a cascade of biochemical reactions that result in the suppression of prostaglandin production. This, in turn, relieves symptoms such as pain and bleeding. Modulating progesterone by taking vilaprisan might help in treating endometriosis over the long term. Phase I and II studies give encouraging results on the efficacy of vilaprisan at different doses. Like other SPRMs, vilaprisan induces benign changes of endometrium (PR modulator-associated endometrial changes, PAECs). These disappear as treatment is discontinued. Unlike GnRHa treatment, neither UPA nor vilaprisan induce hypoestrogenism and associated symptoms. Phase III studies are ongoing to confirm efficacy and safety of vilaprisan in long-term treatment of symptomatic fibroids.

Telapristone acetate, a selective progesterone receptor modulator (SPRM), was developed for the long-term treatment of symptoms associated with endometriosis and uterine fibroids. It is known, that the progesterone is a steroid hormone that plays an important role in the breast. Deregulation of the progesterone-signaling pathway is implicated in the formation, development, and progression of breast cancer. Thus, the telapristone acetate is studied in phase II clinical trial in stage I-II primary breast cancer. Besides, telapristone acetate participated in phase III clinical trials in pre-menopausal anemic women with symptomatic uterine fibroids. However, FDA terminated these studies because of the safety.

Toripristone has a high inhibiting activity against the cortisol receptors. Toripristone enhanced the antibacterial activities of the sparfloxacin in combination with ethambutol in the treatment of M. avium complex infections. Also, toripristone is a glucocorticoid type II receptor and progesterone receptor antagonist. Toripristone treatment was estimated to selectively occupy approximately 50% of glucocorticoid receptors in rat brain.
