Clinical Trial Summary

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.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Cmax of unconjugated and total dabigatran when given without or together with a single oral dose of elinzanetant	Cmax: maximum observed drug concentration in plasma after single dose	Pre-dose and up until 72 hours post-dose of DBG etexilate
Primary	AUC of unconjugated and total dabigatran when given without or together with a single oral dose of elinzanetant	AUC(0-tlast) will be the primary endpoint if AUC cannot be determined in all participants. AUC: area under the concentration vs. time curve from zero to infinity after single dose; AUC(0-tlast): area under the concentration vs. time curve from zero to last quantifiable concentration after single dose	Pre-dose and up until 72 hours post-dose of DBG etexilate
Secondary	Number of participants with treatment-emergent adverse events (TEAEs)		After first study intervention in Period 1 and up to 72.5 hours post-dose of elinzanetant in Period 2 (around 8 days)
Secondary	Number of participants with treatment-emergent adverse events (TEAEs) categorized by severity		After first study intervention in Period 1 and up to 72.5 hours post-dose of elinzanetant in Period 2 (around 8 days)
