Astellas Files NDA for Vasomotor Symptom Therapy
FDA has accepted for priority review an Astellas Pharma NDA for fezolinetant, a nonhormonal selective neurokinin 3 receptor antagonist for treating moderate to severe vasomotor symptoms (hot flashes or night sweats) associated with menopause. The submission is based on data from the BRIGHT SKY program, which includes three Phase 3 clinical trials that enrolled over 2,800 women with vasomotor symptoms. The company used a priority review voucher, which it says will provide a user fee review action target date in the first quarter of 2023.
Fezolinetant is said to work by blocking neurokinin B binding on the kisspeptin/neurokinin/dynorphin neuron to moderate neuronal activity in the thermoregulatory center of the brain (the hypothalamus) to reduce the frequency and severity of moderate to severe vasomotor symptoms.
