Clinical Trial Summary

Researchers are looking for a better way to treat people who have vasomotor symptoms (VMS). VMS such as hot flashes are caused by hormonal changes occurring during menopausal transition when women may have also changes in their monthly cycles. The study treatment, elinzanetant (BAY3427080), was developed to work by blocking neurokinin receptors from working. These receptors can cause changes in the body which can affect hormone levels in men and women. Acid is created by the stomach to help break down and digest food. A type of treatment for overly production of acid by the stomach are called proton pump inhibitors which are currently available for people who have stomach and digestion problems. Proton pump inhibitors work by lowering the amount of acid created by the stomach. In this study, the researchers want to learn about elinzanetant oral bioavailability when taken with a proton pump inhibitor called esomeprazole. They want to learn if taking these drugs together affects the oral bioavailability. The researchers will study how esomeprazole affects the way elinzanetant moves into, through, and out of the body. To do this, the doctors and their team will take blood samples from the participants. These samples will be used to measure the levels of elinzanetant in the participants' blood when it is taken with and without esomeprazole. This study will include healthy adult participants. There will be 2 periods in this study. It is planned that all of the participants will take part in both periods. During Period 1, the participants will take elinzanetant 1 time as a capsule by mouth. The participants will also receive a very small amount of radioactive elinzanetant, also called a microtracer, given through needle in a vein. During Period 2, the participants will take esomeprazole once a day for 5 days as tablets by mouth. On the last day, the participants will also take elinzanetant 1 time as a capsule by mouth. During this study, the participants will visit the study site 3 times. The participants will stay at the study site for 9 days in Period 1 and for 12 days in Period 2. Each participant will be in the study for up to 9 weeks. During the study, the doctors will take urine samples. They will also ask the participants about any medications they have been taking, 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.
