On January 8, 2024, Bayer announced positive top-line results of the pivotal Phase III studies OASIS 1 and 2 evaluating the efficacy and safety of the investigational compound elinzanetant versus placebo. Elinzanetant successfully met all four primary endpoints and all three key secondary endpoints in both studies. Elinzanetant is a first dual neurokinin-1,3 (NK-1,3) receptor antagonist for the non-hormonal treatment of moderate to severe VMS associated with menopause. Elinzanetant may address moderate to severe VMS by modulating a group of estrogen sensitive neurons in the hypothalamus region of the brain (the KNDy neurons) which, with the decrease of estrogen, become hypertrophic and lead to a hyperactivation of the thermoregulatory pathway, consequently disrupting body heat control mechanisms resulting in VMS. Elinzanetant may also decrease sleep disturbances associated with menopause.
