Official title
A Double-blind, Randomized, Placebo-controlled Multicenter Study to Investigate Efficacy and Safety of Elinzanetant for the Treatment of Vasomotor Symptoms Over 26 Weeks in Postmenopausal Women
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Researchers are looking for a better way to treat women who have hot flashes after women have been through the menopause. Hot flashes are caused by the hormonal changes that happen when a woman's body has been through the menopause. Menopause is when women stop having a menstrual cycle, also called a period. During the menopause, 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. The study treatment, elinzanetant, was developed to treat symptoms caused by hormonal changes. It works by blocking a protein called neurokinin from sending signals to other parts of the body, which is thought to play a role in starting hot flashes. There are treatments for hot flashes in women who have been through the menopause, but may cause medical problems for some people. In this study, the researchers will learn how well elinzanetant works compared to a placebo in women who have been through the menopause and have hot flashes. A placebo looks like a treatment but does not have any medicine in it. To compare these study treatments, the doctors will ask the participants to record information about the participants' hot flashes in an electronic diary. The researchers will study the number of hot flashes the participants have and how severe the hot flashes are. The researchers will look at the results from before treatment, after 4 weeks, and after 12 weeks of treatment. The participants in this study will take two capsules of either elinzanetant or the placebo once a day. The participants who take elinzanetant will take it for 26 weeks. The participants who take the placebo will take it for 12 weeks and then take elinzanetant for the next 14 weeks. During the study, the participants will visit the site approximately 9 times and perform 1 visit by phone. Each participant will be in the study for approximately 36 weeks. The treatment duration will be 26 weeks. During the study, the participants will: * record information about the participants' hot flashes in an electronic diary * answer questions about the participants' symptoms The doctors will: * check the participants' health * take blood samples * ask the participants questions about what medicines the participants are taking and if the participants are having adverse events 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 doctors do not think the adverse events might be related to the study treatments.
