These analyses provide valuable insights into the efficacy and safety of VEOZAH in women who are unable or unwilling to take hormone therapy, as well as the efficacy of VEOZAH on VMS experienced at night. The totality of the research being presented adds to our collective knowledge of how VMS impacts individuals and is representative of our commitment to addressing unmet medical needs."

Highlights at the 2023 Annual Meeting of The Menopause Society include:

• Two separate pooled analyses from SKYLIGHT 1 and SKYLIGHT 2 examining the efficacy and safety of fezolinetant in patients unsuitable for or unwilling to take hormone therapy, as well as the efficacy of fezolinetant on night-time VMS episodes
• Pooled data from SKYLIGHT 1, SKYLIGHT 2 and SKYLIGHT 4 assessing the safety and tolerability of fezolinetant over 52 weeks
• A real-world study assessing treatment satisfaction among women with moderate to severe VMS, as well as physicians who treat women with VMS in the U.S.
• Additional presentations highlighting the diverse experiences of women with VMS in the U.S., VMS diagnosis disparities in the U.S. based on sociodemographic characteristics, and the prevalence and impact of VMS among women in Canada

About VEOZAH (fezolinetant)
VEOZAH (fezolinetant) is a neurokinin 3 (NK3) receptor antagonist approved in the U.S. for the treatment of moderate to severe vasomotor symptoms (VMS) due to menopause. VEOZAH is not a hormone. VMS are the feelings of warmth in the face, neck, and chest, or sudden intense feelings of heat and sweating ("hot flashes" or "hot flushes"). VEOZAH works by blocking neurokinin B (NKB) binding on the kisspeptin/neurokinin B/dynorphin (KNDy) neuron to modulate neuronal activity in the thermoregulatory center of the brain (the hypothalamus) to reduce the frequency and severity of moderate to severe VMS due to menopause.
