7. No clinically significant abnormal findings in the medical history, on the physical examination, ECG (corrected QT interval [QTcF] < 450 msec for males and QTcF < 470 msec for females), or clinical laboratory results during screening.
8. Subjects and caregivers must agree to return to the study site for all study visits and must be willing to comply with all required study procedures.

Exclusion Criteria:

1. Subject is undergoing intracranial EEG monitoring.
2. A history of clinically significant gastrointestinal, renal, hepatic, neurologic, hematologic, endocrine, oncologic, pulmonary, immunologic, psychiatric, or cardiovascular disease, severe seasonal or non-seasonal allergies, nasal polyps or any nasal passage abnormality that could interfere with nasal spray administration, or any other condition which, in the opinion of the Investigator, would jeopardize the safety of the subject or impact the validity of the study results.
3. Subject has had significant traumatic injury, major surgery or open biopsy within 30 days prior to study screening.
4. Subjects with active major depression or a past suicide attempt documented on the Baseline/Screening C-SSRS. The children C-SSRS should be used for subjects age 6 to 11. The adult C-SSRS should be used for subjects 12 and greater years of age.

6. A history of allergic or adverse responses to diazepam or any comparable or similar product.
7. Subjects who (for whatever reason) have been on an abnormal diet (such as one that severely restricts specific basic food groups [e.g., ketogenic diet], limits calories [e.g., fast], and/or requires the use of daily supplements as a substitute for the foods typically eaten at mealtimes), during the four (4) weeks preceding the study.
8. Subjects who donated blood or plasma within 30 days of the first dose of study drug.
9. Participation in a clinical trial within 30 days prior to the first dose of study drug. Participation in an observational (non-interventional) study is not excluded as long as there are no scheduling conflicts with this study.
10. Inadequate or difficult venous access that may jeopardize the quality or timing of the PK samples.
11. Female subjects who are trying to conceive, are pregnant, or are lactating.
12. Positive serum pregnancy test (ß-hCG) at screening or urine pregnancy test prior to each administration of study drug for all women of childbearing potential.
13. Positive blood screen on subjects age 12 or greater for human immunodeficiency virus (HIV), Hepatitis B surface antigen (HbSAg), or Hepatitis C, or a positive urine screen for alcohol, drugs of abuse, or cotinine. When marijuana was used for medical reasons in the opinion of the investigator, it is not considered as drug abuse and the patient can be enrolled even if the marijuana metabolites in the urine revealed as positive.
14. Treatment with phenobarbital or primidone within 30 days of the anticipated dosing visit (i.e., baseline).
