VEOZA™ (fezolinetant) is indicated for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause*1

VEOZA is not a hormone

It’s a first-in-class selective NK3 receptor antagonist that blocks NKB from binding on the KNDy neurons to help reduce heat signals that trigger VMS2-4

KNDy=kisspeptin/neurokinin B/dynorphin; NK3=neurokinin 3; NKB=neurokinin B; VMS=vasomotor symptoms

Watch the mechanism of action

Temperature control homeostasis showing the KNDy neuron inhibited by oestrogen and stimulated by NKB

Homeostasis

KNDy neurons in the hypothalamus are inhibited by oestrogen and stimulated by the neuropeptide NKB. The balance between inhibition and activation contributes to body temperature regulation3

Impact of NKB showing how the reduction of oestrogen and unopposed NKB stimulation lead to heightened KNDy neuronal activity

Menopause

Oestrogen decline during the menopausal transition disrupts the balance between activation by NKB and inhibition by oestrogen. Unopposed, NKB signalling causes heightened KNDy neuronal activity.3 This triggers heat dissipation mechanisms, including vasodilation and sweating—VMS3

VEOZA™ (fezolinetant) inhibits binding of NKB to NK3R on the KNDy neuron

Blocking NKB to reduce heat

VEOZA selectively binds to the NK3 receptor to block NKB from binding on the KNDy neuron. This action is postulated to restore the balance in KNDy neuronal activity in the thermoregulatory centre of the hypothalamus2
