Comment: Linzagolix (KLH-2109) is an orally bioavailable gonadotropin-releasing hormone (GnRH) receptor antagonist [5]. It was developed for potential to downregulate the hypothalamic pituitary-gonadal axis to inhibit the driving force of LH and FSH on estrogen release, as a mechanism to combat the symptoms associated with endometriosis [6], heavy menstrual bleeding or uterine fibroids [1,4].
