Application targets treatment of moderate to severe vasomotor symptoms associated (VMS) with menopause
TOKYO, June 23, 2022 /PRNewswire/ -- Astellas Pharma Inc. (TSE: 4503, President and CEO: Kenji Yasukawa, Ph.D., "Astellas") today announced a New Drug Application (NDA) for fezolinetant has been submitted to the U.S. Food and Drug Administration (FDA). Fezolinetant is 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
"In the United States, 60% to 80% of individuals experience VMS during or after the menopausal transition, with limited nonhormonal treatment options," said Ahsan Arozullah, M.D., M.P.H., Senior Vice President and Head of Development Therapeutic Areas, Astellas. "The fezolinetant NDA submission to the U.S. FDA is an important step in our efforts to bring to patients a first-in-class, nonhormonal treatment option to reduce the frequency and severity of moderate to severe VMS associated with menopause."
The NDA submission is based on results from two pivotal Phase 3 clinical trials, SKYLIGHT 1™ and SKYLIGHT 2™, and the Phase 3 long-term safety study, SKYLIGHT 4™.
Fezolinetant is an investigational selective neurokinin 3 (NK3) receptor antagonist. The safety and efficacy of fezolinetant are under investigation and have not been established.
Astellas is reviewing the financial impacts of this submission for the fiscal year ending March 31, 2023.
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.
VMS, characterized by hot flashes (also called hot flushes) and/or night sweats, are common symptoms of menopause.1,2 In the U.S., about 60% to 80% of women experience these symptoms during or after the menopausal transition and, worldwide, more than half of women 40 to 64 years of age experience VMS.3,4,5,6 VMS can have a disruptive impact on women's daily activities and overall quality of life.1
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.3,4,7 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.
