What is Osanetant?

Osanetant is an orally bioavailable, brain-penetrating small-molecule antagonist of neurokinin 3 receptor (NK3R) that blocks NK3R-mediated signaling in the central nervous system. It is being studied to treat vasomotor symptoms in postmenopausal women and men on androgen deprivation therapy, and may suppress hormone secretion including testosterone, luteinizing hormone, and follicle-stimulating hormone.
