This clinical trial is focused on studying a type of cancer known as urothelial cancer, which affects the bladder and other parts of the urinary system. The study is testing a treatment called JNJ-42756493, also known as erdafitinib, which is a medication taken by mouth in the form of a film-coated tablet. The purpose of the study is to evaluate how effective and safe this medication is for patients with urothelial cancer that cannot be removed by surgery or has spread to other parts of the body. The study also looks at how erdafitinib affects the body when taken with other medications, such as midazolam and metformin.
Participants in the study will receive erdafitinib to see how their cancer responds to the treatment. The study will monitor the participants’ health and any changes in their cancer over time. The trial will also assess how erdafitinib interacts with midazolam, which is often used to help with anxiety or sedation, and metformin, a common medication for diabetes. These interactions are important to understand how erdafitinib might affect the way these other drugs work in the body.
The study is designed to gather information on the best dose of erdafitinib and to observe any side effects or benefits experienced by the participants. By doing so, researchers hope to find a treatment option that can help manage urothelial cancer more effectively. The trial is open-label, meaning both the researchers and participants know which treatment is being administered, and it involves multiple centers to ensure a comprehensive evaluation of the medication’s effects.
