In addition, the study aims to assess its effectiveness in influencing the weekly frequency of cataplexy episodes (sudden bouts of muscle weakness) that occur while the individual remains conscious. Other objectives include examining the impact of Samelisant on attention and alertness, overall quality of life, the spectrum of narcolepsy symptoms, and daily functioning, as well as evaluating its safety profile.",[56],"Narcolepsy",[22,26,58,56,59],"Excessive Daytime Sleepiness","Cataplexy","NOT_YET_RECRUITING","2026-06-13",{"date":63,"type":64},"2026-06-16","ACTUAL",{"date":66,"type":50},"2026-06-19",{"date":68,"type":50},"2027-12-19",{"name":5,"class":6}]
