A long-term extension study to assess the safety and tolerability of TAK 861 in participants with selected central hypersomnias
Summary description of the study
We want to investigate the long-term safety and tolerability of several previously tested oral doses of the drug TAK-861 in participants with narcolepsy type 1 (NT1). The investigational drug is not yet approved in Switzerland. Approximately 500 (male and female) participants with narcolepsy type 1 will be assigned a specific dosage and will be asked to take the investigational drug for several years. Participants are only eligible for this study if they have participated in a previous controlled study of TAK-861. In this study, all participants will receive TAK-861, the investigational drug, but will not know which dose they are receiving. The investigational drug is in tablet form and is taken with a large glass of water. The treatment duration is a maximum of 5 years. In the first year of the study, there will be several visit appointments at the study center. Additionally, further visit appointments will be required. These may take place at the study center, at your home with the help of trained medical professionals, or in a blood testing laboratory. After the first year (Year 1), you will have regular visit appointments at the study center until the completion of the study, but with less frequency than in Year 1. You will need to spend one night at the study center or hospital and will be discharged the next day. At certain visit appointments, you may be asked to provide blood and urine samples, undergo an electrocardiogram (ECG), complete questionnaires about your quality of life, and undergo assessments to evaluate your cognitive performance and ability to stay awake. At certain intervals, participants will be asked to keep a diary at home to record their cataplexy and other symptoms. This can conveniently be done via a mobile or tablet application.
