A Trial to Learn What Happens to Different Medicinal Forms of BAY2328065 When They Enter the Body and How Safe They Are in Healthy Male and Female Participants

Study Overview
=================
Brief Summary
-----------------
Researchers are looking for a different way to treat women with a condition in which tissue that normally lines the uterus grows outside the uterus. This condition is called endometriosis. Before a treatment is available to all patients, researchers study it in clinical trials to better understand its safety and what happens to it in the body. BAY2328065 is being developed to help treat women who have endometriosis. Women with endometriosis often have very painful menstrual periods, as well as pain in the pelvic area which is not related to menstrual periods and pain during intercourse. Many women with endometriosis may also have problems becoming pregnant. The trial treatment, BAY2328065, works by blocking a certain protein that causes pain and swelling of the tissue and is thought to play a role in endometriosis. In this trial, the researchers want to compare what happens to different medicinal forms of BAY2328065 in the body. They also want to learn if eating a meal affects what happens to BAY2328065 in the body. This trial will include about 32 men and women who are aged 18 to 55. There will be 4 groups of participants in this trial. The participants in Groups 1, 2, and 3 will be men. The participants in Group 4 will be women. There will be 3 treatment courses to the trial for Groups 1, 2 and 3 and 1 treatment course for Group 4. During the trial, the participants in Groups 1, 2, and 3 will stay at the trial site for 15 days (3 times 5 days with times in between during which they stay at home). The participants in Group 4 will stay at the trial site for 16 days continuously. But, the trial will last about 6 weeks for the participants in Groups 1, 2, and 3. The trial will last about 9 weeks for the participants in Group 4. All of the participants in Groups 1 and 2 will take the different medicinal forms of BAY2328065, with and without food. All of the participants in Groups 1 and 2 will take dose 2 of BAY2328065 in all 3 treatment courses. In Group 1, they will take BAY2328065 one time each during the following treatment courses: A medicinal form of BAY2328065 without food in treatment course 1, then A medicinal form of BAY2328065 differing from the one used in treatment course 1 without food in treatment course 2, then The medicinal form of BAY2328065 used in treatment course 1 with food in treatment course 3 The participants in Group 2 will do the same, but they will take each form of BAY2328065 in a different order. Information gathered from Group 1 and 2 will help the researchers learn which form of BAY2328065 will be most suited to give to the participants in Groups 3 and 4. The participants in Group 3 will take 3 different doses of BAY2328065 with food in each treatment course. They will take one time each during the following treatment courses: Single administration of dose 1 in treatment course 1, then Single administration of dose 2 in treatment course 2, then Single administration of dose 3 in treatment course 3 This will help the researchers learn the safest dose to give to the participants in treatment course 4. The participants in Group 4 will either take dose 3 or 2 of BAY2328065 based on the results of treatment course 3, or a placebo. A placebo looks like a treatment but does not have any medicine in it. All of the participants will take either: Multiple administrations of dose 3 of BAY2328065 or dose 2 of BAY2328065, OR the placebo The participants will take BAY2328065 or placebo over 12 days without food. The doctors/ healthcare staff will: take blood and collect urine samples check the participants' heart health The participants will: answer questions about how they are feeling say if they have any medical problems say if they have taken any medications
