Trial Purpose

Researchers are looking for a better way to treat men and women with vasomotor symptoms, a condition of having hot flashes caused by hormonal changes.
The study drug, elinzanetant, is under development to treat symptoms caused by hormonal changes. It works by blocking a substance called neurokinin from sending signals to other parts of the body, which is thought to play a role in starting hot flashes.
Participants of this study will be healthy and will have no benefit from administration of elinzanetant. This study, however, will provide information on how to use elinzanetant in people with vasomotor symptoms.
The main purpose of this study is to learn whether the study drug elinzanetant (BAY3427080) affects the way the substrate drug dabigatran moves into, through and out of the body.
One way of removing substances such as drugs from the body are proteins which act as transporters. One such transporter is called P-gp. As a so-called substrate of P-gp, dabigatran is typically removed from the body by P-gp transporters.
The activity of transporters can be increased by substances called inducers and decreased by substances called inhibitors. It has been found in laboratory experiments that the study drug elinzanetant is a weak inhibitor of the P-gp transporter. Inhibition of this transporter can lead to an increase in the amount of drugs such as dabigatran in the blood.
This study is therefore needed to make recommendations on how elinzanetant can be used safely together with other drugs that are removed from the body by the P-gp transporter.
To answer this, the researchers will compare
• the average highest level of dabigatran in the blood (also referred to as Cmax)
• the average total level of dabigatran in the blood (also referred to as AUC)
when dabigatran is given alone and is given together with elinzanetant.
All participants will take one dose of dabigatran by mouth in the first period of the study. And after 4 days, the participants will take one dose of elinzanetant by mouth and at 30 minutes later, one dose of dabigatran by mouth during the second period of the study. The total duration of individual study participation will be about 4.5 weeks including the screening period. Each participant will stay in the center for 9 days with 8 overnight stays.
During the study, the study team will:
• take blood and urine samples
• do physical examinations
• check the participants’ overall health
• examine heart health using ECG
• check vital signs
• ask the participants questions about how they are feeling and what adverse events they are having.
An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think the adverse events might be related to the study treatments.

Inclusion Criteria
- Participant must be 18 to 65 years of age inclusive, at the time of signing the informed consent.
- Participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, blood pressure (BP), pulse rate, 12-lead electrocardiogram (ECG), and laboratory tests.
- Body weight of at least 50 kg and body mass index (BMI) above or equal 18.0 and below or equal 30.0 kg/m² at screening.
- Male or female
- Contraceptive use by men and women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.
Exclusion Criteria
- Known hypersensitivity to any study intervention (active substances or excipients of the preparations) to be used in the study.
- Thyroid-stimulating hormone (TSH) outside normal range at screening.
- Any lesion or condition considered a significant risk factor for major bleeding.
- Known or suspected coagulopathies.
- Estimated glomerular filtration rate (eGFR according to Chronic Kidney Disease Epidemiology Collaboration; CKD-EPI) below 90 mL/min/1.73 m2 at screening.
- Any use of systemic or topically active medication or herbal remedies, prescription or non-prescription, within 2 weeks or 5 half-lives (whichever longer) prior to the first study intervention administration.
- Suspicion of drug or alcohol abuse.
- Smoker (current, or within 6 months before screening).
