Cómo lo describe el promotor
En el documentoEn inglés, del registroIn this study, researchers will learn more about the safety of tofersen, also known as Qalsody®. This is a drug available for doctors to prescribe for people with a certain type of amyotrophic lateral sclerosis, also known as ALS. This type is in people who have a mutation in the superoxide dismutase 1 gene, also known as SOD-1. This is known as a "postmarketing" study. In this kind of the study, the goal is to learn more about how a drug works after it has been approved for use in the general public. Tofersen was approved in China in September 2024. The main goal of this study is to collect long-term safety information in Chinese participants with SOD-1 ALS. The main question researchers want to answer in this study is: • How many participants have adverse events (AEs) and serious adverse events (SAEs)? An AE is a health problem that may or may not be caused by a drug during the study. An AE is considered serious when it results in death, is life-threatening, causes lasting problems, or requires hospital care. Researchers will also learn more about : * How the body processes tofersen. * How much tofersen is found in the cerebrospinal fluid (CSF), or the fluid that surrounds the brain and the spinal cord. This study will be done as follows: * Participants will be screened to check if they can join the study. The screening period will be up to 4 weeks. * After joining the study, participants will receive the first 3 doses of 100 milligrams (mg) of tofersen about 14 days apart. This will be given through an intrathecal (IT) injection. This means it will be given into the fluid surrounding the spine. * After that, participants will receive 10 more doses every 28 days through IT injections. Participants will have up to 13 total doses of tofersen in this study. * Participants will have up to 15 visits to their study research center. Each participant will be in the study for up to 52 weeks (1 year).
