A Study to Learn How Much Rosuvastatin Gets Into the Blood When Taken With or Without Elinzanetant and to Learn About the Safety of Elinzanetant in Healthy Participants

Researchers are looking for a better way to treat people who have symptoms caused by hormonal changes, like those that happen in women during menopause. These symptoms can include vasomotor symptoms. Before a treatment can be approved for patients to take, researchers do clinical studies to better understand its safety and what happens to the treatment in the body.

The study drug, elinzanetant, was designed to treat vasomotor symptoms. Rosuvastatin is already approved for doctors to prescribe and is used to treat high cholesterol levels and prevent heart problems. It is important for researchers to know if taking elinzanetant will affect how other drugs work in the body. Researchers regularly use rosuvastatin in studies to learn how it affects drugs like elinzanetant.In this study, the researchers will study how much elinzanetant gets into the participants' blood when taken with or without rosuvastatin. The study will include about 16 male participants who are between 18 and 65 years old. The participants will all take 5 milligrams (mg) of rosuvastatin and 120 mg of elinzanetant as capsules by mouth. On some days, they will take only rosuvastatin or only elinzanetant. On other days, they will take both study treatments. Each participant will be in the study for up to 6 weeks. But, the entire study will last about 2.5 months.

During the study, all of the participants will stay at the study site for 17 days. Blood and urine samples will be collected. The physician will also check the participants' heart health using an electrocardiogram (ECG). The participants will answer questions about how their well being and taken medications.


Eligibility Criteria:
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, laboratory tests, and ECG, vital signs, respiratory rate and body temperature.Weight.

  -- a. Male participants:
  * Male participants of reproductive potential must agree to use a condom (with or without spermicide) when sexually active. This applies for the time period between the signing of the informed consent form until 7 days after the last dose of study intervention.
  * Female partners of childbearing potential of male participants do not need to follow special precautions.
* Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the informed consent form (ICF) and in this protocol

Exclusion Criteria:

* History or evidence of any clinically relevant cardiovascular, gastrointestinal, endocrine, hematologic, hepatic, immunologic, metabolic, urologic, pulmonary, neurologic, dermatologic, psychiatric, renal and/or other clinically relevant disease, as judged by the investigator.
* Pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study intervention will not be normal.
* Use of any systemic or topical medicines or substances which oppose the study objectives, or which might influence them (for further information, see Section 6.8) within 4 weeks prior to screening.
* Participants with positive serology for any of hepatitis B, hepatitis C, of HIV.
* Clinically relevant deviations of the screened safety laboratory parameters in clinical chemistry, hematology, or urinalysis from reference ranges.

* Participants with a presence of any of the following, confirmed by a repeat test: AST, alanine aminotransferase (ALT) and/or bilirubin above 1.2 x upper limit of normal (ULN) (at screening or Day -1).
* Known intolerance to statins.
