First-in-class treatment option reduces number and intensity of hot flashes and night sweats 

TOKYO, Dec. 10, 2023 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Naoki Okamura, "Astellas") today announced the European Commission (EC) on December 7 approved VEOZA^TM (fezolinetant) 45 mg once daily for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause. 

VMS, also known as hot flashes and/or night sweats, are common symptoms of menopause.^1,2 Worldwide, more than half of women 40 to 64 years of age experience VMS, with rates in Europe ranging from 56% to 97%.^3,4,5 The prevalence of moderate to severe VMS in postmenopausal women in Europe has been reported at 40%.⁶ VMS can have a disruptive impact on women's daily activities and overall quality of life.²

Prof. Rossella Nappi, Full Professor of Obstetrics and Gynecology, Chief of the Research Center for Reproductive Medicine and Director of the Gynecological Endocrinology & Menopause Unit, IRCCS San Matteo Foundation, University of Pavia 
"I've been awaiting the marketing authorization of fezolinetant. I'm happy to see this advancement in women's health and that my patients will soon have this new nonhormonal treatment option available to better control their moderate to severe VMS."

Marci English, Vice President, Head of BioPharma Development, Astellas
"Fezolinetant's novel mechanism of action targets the root cause of moderate to severe VMS associated with menopause. We are proud to have developed an innovative treatment option for a condition that has lacked scientific advancement for too long and look forward to making fezolinetant available in countries across the European Union."

Before menopause, there is a balance between estrogens, a female sex hormone, and a protein made by the brain known as neurokinin B (NKB) that regulates the brain's temperature control center. As the body goes through menopause, estrogen levels decline and this balance is disrupted, which can lead to VMS. By blocking NKB binding in the temperature control center, fezolinetant reduces the number and intensity of hot flashes and night sweats.

This approval follows a positive opinion issued in October by the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) based on the results from the BRIGHT SKY™ program, which included three Phase 3 clinical trials as part of a development program that collectively enrolled over 3,000 across Europe, the U.S. and Canada. Results from the SKYLIGHT 1™ and SKYLIGHT 2™ pivotal trials characterize the efficacy and safety of fezolinetant for the treatment of moderate to severe VMS associated with menopause and were published in The Lancet and The Journal of Clinical Endocrinology & Metabolism, respectively.^7,8 Data from the SKYLIGHT 4™ safety study further characterizes the long-term safety profile of fezolinetant and was published in Obstetrics & Gynecology.⁹

The EC marketing authorization for fezolinetant is applicable in the European Union (EU) Member States, as well as Iceland, Norway and Liechtenstein.¹⁰ Fezolinetant was also approved in Switzerland on December 4, 2023.

Astellas has already reflected the impact from this matter in its financial forecast of the current fiscal year ending March 31, 2024.

About the BRIGHT SKY™ Phase 3 Program
The BRIGHT SKY pivotal trials, SKYLIGHT 1™ (NCT04003155) and SKYLIGHT 2™ (NCT04003142), enrolled over 1,000 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 women with VMS were enrolled at over 180 sites within the U.S., Canada and Europe.

About VEOZA™ (fezolinetant)
VEOZA (fezolinetant) is a nonhormonal neurokinin 3 (NK3) receptor antagonist indicated in the EU and European Economic Area countries for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause. VMS are also known as hot flashes or night sweats. VEOZA 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 number and intensity of hot flashes and night sweats.^11,12,13
