This clinical trial focuses on studying neurodegenerative diseases, which are conditions that affect the brain and nervous system, leading to a gradual decline in mental and physical abilities. The study uses a special imaging technique called tau PET to help identify early signs of these diseases. The treatment being tested is a solution for injection known as [18F]RO6958948, also referred to as RO948 (18F). This solution contains a chemical substance that helps in visualizing certain brain processes during imaging.
The purpose of the study is to explore how this imaging method can be used to detect changes in the brain that are associated with neurodegenerative diseases. Participants will receive injections of the solution and undergo imaging scans to map the presence of tau, a protein that can build up in the brain and is linked to these diseases. The study will also involve some participants receiving a placebo, which is a substance with no active treatment, to compare results.
Throughout the study, participants will have regular imaging sessions and may undergo additional tests to measure various substances in the body, such as proteins in the blood and cerebrospinal fluid. These tests help researchers understand how the disease progresses and how the treatment affects the brain. The study aims to provide valuable insights into the early detection and understanding of neurodegenerative diseases, potentially leading to better treatment options in the future.
