If authorized by the European Commission, fezolinetant would be a nonhormonal treatment for moderate to severe vasomotor symptoms associated with menopause
TOKYO, Japan I September 29, 2022 I Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., “Astellas”) today announced the European Medicines Agency (EMA) has accepted for regulatory review the company’s marketing authorization application (MAA) for fezolinetant, an investigational oral, nonhormonal compound seeking approval for the treatment of moderate to severe vasomotor symptoms (VMS) associated with menopause. VMS, characterized by hot flashes and/or night sweats, are common symptoms of menopause.1,2
“More than half of women 40 to 64 years of age experience hot flashes during menopause, with limited nonhormonal treatment options,” said Ahsan Arozullah, M.D., M.P.H., Senior Vice President and Head of Development Therapeutic Areas, Astellas. “The EMA’s acceptance of our MAA for fezolinetant brings us one step closer to advancing a potential first-in-class nonhormonal treatment option for women in Europe who experience VMS associated with menopause, similar to the FDA acceptance of our NDA for women in the U.S.”
The MAA is supported by results from the BRIGHT SKY™ program, which included three Phase 3 clinical trials that collectively enrolled over 2,800 women with VMS 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. Data from the SKYLIGHT 4™ safety study further characterizes the long-term safety profile of fezolinetant. Within the MAA, Astellas proposes a 45 mg daily dose, which is subject to the EMA’s review.
Fezolinetant is an investigational nonhormonal selective neurokinin 3 (NK3) receptor antagonist. The safety and efficacy of fezolinetant are under investigation and have not been established.
This acceptance will have no impact on Astellas’ financial forecasts of the current fiscal year ending March 31, 2023.
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 VMS Associated with Menopause
VMS, characterized by hot flashes (also called hot flushes) 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.1
About Fezolinetant
Fezolinetant is an investigational oral, nonhormonal therapy in clinical development for the treatment of moderate to severe VMS associated with menopause. Fezolinetant works by blocking neurokinin B (NKB) binding on the kisspeptin/neurokinin/dynorphin (KNDy) neuron to moderate neuronal activity in the thermoregulatory center of the brain (the hypothalamus) to reduce the frequency and severity of moderate to severe VMS associated with menopause.7,8,9 The safety and efficacy of fezolinetant are under investigation and have not been established. There is no guarantee the agent will receive regulatory approval or become commercially available for the uses being investigated.
