Principal exclusion criteria

1. Participant has a moderate or severe ongoing treatment emergent adverse event (TEAE) related to the study drug from the parent study or discontinued because of TEAEs in the parent study.

4. Participant has alanine aminotransferase (ALT) and aspartate aminotransferase (AST) >1.5 times the upper limit of normal (ULN) at multiple visits in the parent study and the findings are of clinical significance, per investigator or sponsor opinion, or ALT/AST >1.5 times ULN during the screening period for participants with a dosing gap.
5. Participant has a current medical disorder, other than narcolepsy with or without cataplexy, associated with excessive daytime sleepiness (EDS).
6. Participant has current active major depressive episode (MDE) or has had an active MDE in the past 6 months.
7. Participant has developed (within the last 6 months) gastrointestinal disease that is expected to influence the absorption of drugs (i.e., a history of malabsorption, esophageal reflux, peptic ulcer disease, erosive esophagitis, frequent [more than once per week] occurrence of heartburn, or any surgical intervention).
8. Participant has epilepsy or history of seizure.
9. Participant has any other medical condition, such as anxiety, depression, heart disease, or significant hepatic, pulmonary, or renal disease, that requires them to take excluded medications.
10. Participant has a history of cerebral ischemia, transient ischemic attack (<5 years ago), or cerebral hemorrhage.
11. Participant has a history of myocardial infarction, clinically significant coronary artery disease, clinically significant angina, clinically significant cardiac rhythm abnormality, or heart failure.
