Bayer today announced positive topline results of the Phase III study OASIS 3 evaluating the efficacy and long-term safety of the investigational compound elinzanetant versus placebo. In this study, elinzanetant successfully met the primary endpoint demonstrating statistically significant reduction in the frequency of moderate to severe vasomotor symptoms (VMS, also known as hot flashes) from baseline to week 12 compared to placebo. The long-term safety profile observed over 52 weeks in the OASIS 3 study is overall consistent with previously conducted studies and published data on elinzanetant.
“It is critical that we continue to broaden therapeutic options that will effectively meet the significant needs of menopausal women”

“OASIS 3 was designed to address the important question of the long-term profile of elinzanetant. With the positive topline results of OASIS 3 adding to the existing evidence from OASIS 1 and 2, elinzanetant has consistently shown positive data across all Phase III clinical trials in the treatment of moderate to severe VMS associated with menopause,” said Dr. Christian Rommel, member of the Executive Committee of Bayer AG’s Pharmaceutical Division and Global Head of Research and Development. “We are looking forward to sharing the full data at upcoming medical conferences as we move towards submitting to health authorities.”
Elinzanetant is the first dual neurokinin (NK-1,3) receptor antagonist, in late-stage clinical development for the non-hormonal treatment of moderate to severe VMS associated with menopause, administered orally once daily.
“It is critical that we continue to broaden therapeutic options that will effectively meet the significant needs of menopausal women,” said Nick Panay, Principal Investigator for OASIS 3, Consultant Gynaecologist, Imperial College Healthcare NHS Trust, Professor of Practice, Imperial College London and President of International Menopause Society. “These results, coupled with the recent announcement of topline data for OASIS 1 and OASIS 2, strengthen our confidence in the proposed efficacy and safety of elinzanetant as a potential novel non-hormonal solution for women experiencing menopause-related symptoms.”
OASIS 3 (NCT05030584) is the third Phase III study in the OASIS clinical development program with positive topline results. In early 2024, Bayer announced topline data of the first two Phase III studies OASIS 1 and 2 (NCT05042362 and NCT05099159) which met all primary and key secondary endpoints. The results of all three studies will be presented at upcoming scientific congresses. Bayer will submit the data from the OASIS 1, 2 and 3 studies to health authorities for approval of marketing authorizations of elinzanetant for the treatment of moderate to severe VMS associated with menopause.

About the OASIS 1, 2 and 3 studies
OASIS 1 and 2 are double-blind, randomized, placebo-controlled multicenter studies investigating the efficacy and safety of elinzanetant administered orally once daily in women with moderate to severe VMS associated with menopause over 26 weeks. OASIS 1 and 2 randomized 396 and 400 postmenopausal women between 40 and 65 years across 184 sites in 15 countries. OASIS 3 is a double-blind, randomized, placebo-controlled multicenter study to investigate the efficacy and safety of elinzanetant for the treatment of vasomotor symptoms over 52 weeks in postmenopausal women. OASIS 3 randomized 628 postmenopausal women between 40 and 65 years across 83 sites in 9 countries.
About the OASIS Clinical Development Program
The Phase III clinical development program of elinzanetant, OASIS, currently comprises four Phase III studies: OASIS 1, 2, 3 and 4. The OASIS 1, 2 and 3 studies investigate the efficacy and safety of elinzanetant 120 mg in women with moderate to severe VMS associated with menopause. The OASIS 4 study is an expansion of the clinical phase III program and investigates the efficacy and safety of elinzanetant in women with moderate to severe VMS caused by endocrine therapy for treatment or prevention of breast cancer.
The design and dosing of the Phase III clinical development program is based on the positive data from two Phase II studies (RELENT-1 and SWITCH-1). RELENT-1 was a Phase Ib/IIa study investigating the safety, pharmacokinetics and preliminary efficacy of elinzanetant. SWITCH-1 was a Phase IIb study investigating the efficacy and safety of four different doses of elinzanetant compared to placebo in women with VMS.
About Elinzanetant
Elinzanetant is the first dual neurokinin-1,3 (NK-1,3) receptor antagonist, in late-stage clinical development for the non-hormonal treatment of moderate to severe VMS associated with menopause, administered orally once daily. 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.
