A Trial of TAK-861 for the Treatment of Narcolepsy With Cataplexy

This study is testing a new medicine, TAK-861, for narcolepsy with cataplexy. We want to see how well it works, how long its effects last, and if it's safe. Participants will take the drug, then some will switch to a dummy pill to observe their symptoms.
