All Clinical Trials for ELINZANETANT

Trial ID Title Status Sponsor Phase Start Date Summary
NCT04845841 ↗ Comparison of the Extent to Which the Drug Given as Two Different Capsule Sizes Becomes Available to the Body Completed Bayer Phase 1 2021-04-09 Researchers are looking for a new way to treat women who have symptoms by hormonal changes, like those that happen in women during menopause. These symptoms can include hot flashes, night sweats, and changes in blood pressure. These symptoms are caused by hormonal changes occurring during menopausal transition when women may have also changes in their monthly cycles. The menopausal transition most often begins between ages 45 and 55 and leads to menopause, a point in time 12 months after a woman's last period. The study drug, elinzanetant, was designed to treat symptoms caused by hormonal changes. Before a new treatment can be approved for people to take, researchers perform clinical trials to better understand how this treatment works and to investigate safety. The purpose of this study is to assess the blood levels of elinzanetant when given as 2 capsules of dose A (what is intended for further research and future commercialization) and also to compare the blood levels when given as 3 capsules of dose B (what was used for research up to now). Furthermore, researchers want to find out if taking of elinzanetant on two time points leads to differences in blood levels of elinzanetant. This trial will be performed in healthy women aged 40 to 65 years.
NCT04889287 ↗ 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 Completed Bayer Phase 1 2021-05-26 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.
NCT04903821 ↗ A Study to Learn How Different Levels of Decreased Liver Function Influence Blood Levels of Elinzanetant Compared to Normal Liver Function in Male and Female Participants Recruiting Bayer Phase 1 2021-06-01 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.
NCT04981431 ↗ A Study to Learn How Safe Elinzanetant is, How it Affects the Body, and How it Moves Into, Through and Out of the Body After Single and Multiple Doses in Japanese Healthy Female Adults Recruiting Bayer Phase 1 2021-08-11 Researchers are looking for a new way to treat women who have symptoms that are caused by the sex hormonal changes that happen when a woman's body is going through the menopause. These symptoms include Vasomotor Symptoms (VMS) (hot flashes), and changes in blood pressure. Menopause is when women stop having a menstrual cycle, also called a period. During the period, the ovaries increasingly produce less sex hormones as a result of the natural ageing process and related hormonal adjustments. The decline in hormone production can lead to various symptoms which, in some cases, can have a very adverse effect on a menopausal woman's quality of life. In this study, researchers want to learn more about a new substance called elinzanetant. Elinzanetant was developed to treat symptoms caused by sex hormonal changes. It works by blocking a group of proteins called neurokinins from sending signals to other parts of the body, which play a role in starting the symptoms. In this study, the researchers will learn how safe elinzanetant is and how it affects the body of healthy Japanese women compared to a placebo. A placebo is a treatment that looks like a medicine but does not have any medicine in it. Before a new treatment can be given to patients, researchers do studies in healthy participants to learn more about its safety and how it acts in the body. There will be 2 parts to this study. In Part A, the participants will take a single dose of either elinzanetant or the placebo. In Part B, the participants will take multiple doses of elinzanetant or the placebo. The participants will take each study treatment as capsules by mouth. The main purpose of this study is to learn how safe elinzanetant is and how it affects the body. To answer this question, the researchers will collect the medical problems the participants have after receiving the treatment and that may or may not be related to the study treatment. These medical problems are also known as "adverse events". During Part A, the participants will stay at their study site for a total of 9 days. They will take either elinzanetant or the placebo only on Day 1 of their stay. During Part B, the participants will stay at their study site for a total of 15 days. They will take either elinzanetant or the placebo once a day for 7 days of their stay. Each participant will be in the study for a total of approximately 5 weeks for Part A and approximately 6 weeks for Part B. During the study, the doctors will: - take blood and urine samples; - check the participants' health; - ask the participants questions about what medicines they are taking and if they are having adverse events.
