TAK-385 is a luteinizing hormone-releasing hormone (LH-RH) receptor antagonist administered orally. By preventing LH-RH from binding with the LH-RH receptor in the anterior pituitary gland and suppressing the secretion of luteinizing hormone (LH)  and follicle stimulation hormone (FSH) from the anterior pituitary gland, TAK-385 controls the effect of LH and FSH on the ovary, reduces the level of estrogen in blood, which is known to be associated with the development of endometriosis and uterine fibroids, and is expected to improve the symptoms of these disorders.

TAK-385 in Japan for the treatment of endometriosis and uterine fibroids. TAK-385 is a luteinizing hormone-releasing hormone (LH-RH) *1 receptor antagonist administered orally. By preventing LH-RH from binding with the LH-RH receptor in the anterior pituitary gland and suppressing the secretion of luteinizing hormone (LH) *2 and follicle stimulation hormone (FSH) *3 from the anterior pituitary gland, TAK-385 controls the effect of LH and FSH on the ovary, reduces the level of estrogen in blood, which is known to be associated with the development of endometriosis and uterine fibroids, and is expected to improve the symptoms of these disorders. The safety and efficacy of TAK-385 in subjects with endometriosis and uterine fibroids will be evaluated in two individual phase 2, double-blind, comparative studies. There are medical needs which cannot be met by the current therapies in the treatment of endometriosis and uterine fibroids. We are committed to the rapid development to deliver the oral LH-RH antagonist TAK-385, which could become a new treatment option for patients with these conditions.

  • *1 The hormone that controls the secretion of LH and FSH, gonadotropic hormones, secreted from the anterior pituitary gland.
  • *2 A hormone that is secreted from the anterior pituitary gland by the action of LH-RH and encourages follicular maturation, ovulation and luteinization by acting on the ovaries.
  • *3 A hormone that is secreted from the anterior pituitary gland by the action of LH-RH and encourages follicular maturation by stimulating the ovaries.

TAK-385, an oral antagonist of gonadotropin-releasing hormone (GnRH), was originated by Takeda. It is in phase II clinical trials for the treatment of endometriosis and for the treatment of uterine fibroids (myoma). Phase I clinical trials are also underway for the treatment of prostate cancer.

TAK-385 (relugolix) is a novel, non-peptide, orally active gonadotropin-releasing hormone (GnRH) antagonist, which builds on previous work with non-peptide GnRH antagonist TAK-013. TAK-385 possesses higher affinity and more potent antagonistic activity for human and monkey GnRH receptors compared with TAK-013. Both TAK-385 and TAK-013 have low affinity for the rat GnRH receptor, making them difficult to evaluate in rodent models. Here we report the human GnRH receptor knock-in mouse as a humanized model to investigate pharmacological properties of these compounds on gonadal function. Twice-daily oral administration of TAK-013 (10 mg/kg) for 4 weeks decreased the weights of testes and ventral prostate in male knock-in mice but not in male wild-type mice, demonstrating the validity of this model to evaluate antagonists for the human GnRH receptor.
The same dose of TAK-385 also reduced the prostate weight to castrate levels in male knock-in mice. In female knock-in mice, twice-daily oral administration of TAK-385 (100 mg/kg) induced constant diestrous phases within the first week, decreased the uterus weight to ovariectomized levels and downregulated GnRH receptor mRNA in the pituitary after 4 weeks. Gonadal function of TAK-385-treated knock-in mice began to recover after 5 days and almost completely recovered within 14 days after drug withdrawal in both sexes. Our findings demonstrate that TAK-385 acts as an antagonist for human GnRH receptor in vivo and daily oral administration potently, continuously and reversibly suppresses the hypothalamic–pituitary–gonadal axis. TAK-385 may provide useful therapeutic interventions in hormone-dependent diseases including endometriosis, uterine fibroids and prostate cancer.
