About

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. The liver plays an important role in removing elinzanetant from the body. Therefore, this study is done to find out how reduced liver function influences the removal of elinzanetant.

The study will include male and female participants who are 18 to 75 years old. One part of the participants will have mildly or moderately impaired hepatic function. For each group with impaired hepatic function, a group with normal hepatic function will be included.

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 their well-being and taken medications.

The researchers will compare the blood levels of elinzanetant in the participants with impaired hepatic function to those of the matched participants with normal hepatic function. This way, they can see how blood levels of elinzanetant are influenced by liver function. This information is important for giving recommendations on dosing in patients with impaired hepatic function.

Enrollment: 33 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Participant must be 18 to 75 years of age inclusive, at the time of signing the informed consent.

• Participants who have

  • Impaired hepatic function according to Child-Pugh score A or B,
  • Documented medical history of liver cirrhosis confirmed by either histopathology, laparoscopy, fibroscan, computer tomography, magnetic resonance imaging (MRI), or ultrasound,
  • Stable impairment for at least 2 months prior to screening in the judgment of the investigator.

• Participants who have normal hepatic function and are overtly healthy.

• Body weight of at least 50 kg and BMI within the range 18 to 38 kg/m*2 (inclusive).

• Male or female Contraceptive use by men or women should be consistent with local regulations regarding the methods of contraception for those participating in clinical studies.

  • Male participants:

    • Male participants of reproductive potential must agree to use a condom (with or without spermicide) when heterosexually active. This applies for the time period between the signing of the informed consent form (ICF) until 7 days after the last dose of study intervention.
    • Female partners of male participants do not need to follow special precautions.

  • Female participants of childbearing potential: have to agree to use a highly effective non-hormonal contraception when heterosexually active. This applies for the time between signing the ICF until 21 days after the last dose of study intervention (for details and definitions of childbearing potential and allowed contraceptive methods).

• Female participants of childbearing potential must have a negative pregnancy test at screening and on Day -1.

• Capable of giving signed informed consent which includes compliance with the requirements and restrictions listed in the ICF and in this protocol.

Exclusion criteria

• Ascites qualitatively estimated as severe or requiring acute or frequent paracentesis.
• Renal failure with an estimated glomerular filtration rate (eGFR) <= 40 mL/min according to Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
• Encephalopathy of > grade 2.
• Renal failure with an eGFR <=60 mL/min CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation.
• Any clinically relevant disease (other than those related to hepatic impairment for the hepatic impaired participants) within 4 weeks prior to study drug administration including.
• Medically relevant infections and acute gastro-intestinal diseases (vomiting, diarrhea, constipation).
• Severe cerebrovascular or cardiovascular disorders less than 6 months prior to dosing, e.g., stroke, myocardial infarction, unstable angina pectoris, congestive heart failure of grade III or IV according to New York Heart Association (NYHA), arrhythmia requiring antiarrhythmic treatment, percutaneous transluminal coronary angioplasty or coronary artery bypass graft.
• Febrile illness within 1 week before first study drug administration.
