TOKYO, Oct. 14, 2025 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") today announced that VEOZAH™ (fezolinetant), its first-in-class, targeted, non-hormonal treatment for moderate to severe vasomotor symptoms (VMS) due to menopause, will be featured in six Astellas-sponsored poster presentations during The Menopause Society 2025 Annual Meeting in Orlando, Florida, October 21-25. VMS, also known as hot flashes and/or night sweats, are common symptoms of menopause.1,2
The presentations, which feature three Late Breaking Abstracts (LBA), will include two preliminary analyses from the OPTION-VMS study. These analyses evaluate, in a real-world setting, both the changes in the impact VMS among women beginning non-hormonal therapy (non-HT) for VMS and the effects on work productivity for women initiating non-HT to manage these symptoms. These results highlight Astellas' commitment to expanding clinical knowledge about VEOZAH beyond the pivotal trials to help improve the lives of all those impacted by VMS due to menopause.
Karla Martins, Executive Medical Director for Global Medical Affairs, Astellas
"Astellas is dedicated to expanding the clinical understanding of our medicines. We are pleased to share comprehensive data on fezolinetant at this year's TMS meeting. These results provide further evidence of the efficacy and safety of fezolinetant as a treatment option for moderate to severe VMS due to menopause."
Fezolinetant data to be presented as posters during the 2025 Annual Meeting of The Menopause Society include:
An additional poster presentation will highlight results from a survey to understand factors contributing to healthcare and treatment perceptions for menopause and related VMS among non-Hispanic/Latino black or African American women in the US.
Posters will be presented on Thursday, October 23, 6:15 – 7:15 PM.
About OPTION-VMS
OPTION-VMS (NCT06049797) is an ongoing Phase IV, longitudinal, observational, study on women aged 40-75 years with confirmed menopausal VMS who were prescribed a non-hormonal therapy (non-HT) for the treatment of bothersome VMS by their healthcare provider in a real-world setting. The primary objective of the study is to evaluate the change in VMS bother in women; additional outcomes include sleep quality, menopause-related quality of life, sexual health, mood and work productivity. A total of 998 women were enrolled at 50 sites in the U.S.
About the BRIGHT SKY™ Phase 3 Program
The BRIGHT SKY pivotal trials, SKYLIGHT 1™ (NCT04003155) and SKYLIGHT 2™ (NCT04003142), enrolled over 1,000 menopausal women with moderate to severe VMS. The trials are double-blinded, placebo-controlled for the first 12 weeks followed by a 40-week treatment extension period. Women were enrolled at over 180 sites within the U.S., Canada and Europe. SKYLIGHT 4™ (NCT04003389) is a 52-week double-blinded, placebo-controlled study designed to investigate the long-term safety of fezolinetant. For SKYLIGHT 4, over 1,800 menopausal women with VMS were enrolled at over 180 sites within the U.S., Canada and Europe.
About VEOZAH™ (fezolinetant)
VEOZAH (fezolinetant) is a nonhormonal neurokinin 3 (NK3) receptor antagonist indicated in the United States for the treatment of moderate to severe vasomotor symptoms (hot flashes and night sweats) due to menopause. VEOZAH works by blocking neurokinin B (NKB) binding on the kisspeptin/neurokinin/ dynorphin (KNDy) neuron to modulate neuronal activity in the brain's temperature control center (the hypothalamus) to reduce the frequency and severity of moderate to severe VMS due to menopause 3,4,5
