Brief summary
This study will assess long-term safety and tolerability of repeat dose diazepam nasal spray in adolescents and adults with cluster seizures, with a focus on potential local effects (changes in nasal mucosa, olfaction, and taste).

Inclusion criteria
* Diagnosis of drug-resistant epilepsy * Patients who experience multiple episodes of acute repetitive seizures requiring at least one concomitant antiepileptic drug (AED) * Occurrence of at least 3 seizure clusters within the past 12 months, including at least one cluster in the 4 months prior to the Screening Visit * A caregiver must consent to participate together with the subject for purposes of observation and data collection * The caregiver must be present when the investigational product is administered * Screening body weight between 26 to 111 kg, inclusive
Exclusion criteria
* Female subject who is pregnant, breastfeeding, or planning to become pregnant * Presence or history of any abnormality or illness that may affect the absorption, distribution, metabolism or elimination of diazepam * Known allergy or hypersensitivity to diazepam, related drugs, or any of the formulation components * Positive screening test for ethanol or other drugs of abuse * Unable to receive medications intranasally

| Olfactory Changes as Measured by the Smell Identification Test (SIT) | Screening, weeks 12, 24, 36, 48 and 51 | The SIT is a 50-item multiple-choice standardized test of olfactory function. Scoring of the test in the ability to smell ranges from normal (Normosmia: score 35 - 40 Women; 34 - 40 Men); to inability to smell (Anosmia score 6 - 18); or Malingering (not engaged in the test) ranges 0 - 5. |
| Change From Baseline (Screening) in Nasal Mucosa. | Screening, Weeks 12, 24, 36, 48 and 51 | Change from baseline treatment visits using a focused nasal exam was based on a scale of nasal irritation none to Grade 4 septal perforation. |
| Change in Taste as Measured by a Taste Change Questionnaire | Weeks 12, 24 | Change in taste questionnaire was administered to subjects at every study visit only if the subject complained of a change in taste or as needed to report a related AE. The taste change profile included sweet, salty, sour, bitter, oily, sharp, chalky, metallic. The subject rated the change on a 10-point scale ranging from a weak change (1) to very strong (10). |

Recruitment details
Adolescents or adults who have refractory epilepsy (drug resistant epilepsy per Kwan 2010) with a history of cluster seizures, also known as multiple episodes of acute repetitive seizures, for which acute treatment with a benzodiazepine was indicated as part of the standard of care or an individualized rescue treatment plan.

Change in Taste as Measured by a Taste Change Questionnaire
Change in taste questionnaire was administered to subjects at every study visit only if the subject complained of a change in taste or as needed to report a related AE. The taste change profile included sweet, salty, sour, bitter, oily, sharp, chalky, metallic. The subject rated the change on a 10-point scale ranging from a weak change (1) to very strong (10).
Time frame: Weeks 12, 24
Population: Safety Population - Number of subjects with at least one change in taste after dose administration. 6 Adults at 12 Weeks and 4 Adults at 24 weeks. No Adolescents participated.
| Arm | Measure | Group | Value (MEAN) | Dispersion |
|---|---|---|---|---|
| Diazepam Nasal Spray (Adults) | Change in Taste as Measured by a Taste Change Questionnaire | Week 12 | 7.7 units on a scale | Standard Deviation 2.73 |
| Diazepam Nasal Spray (Adults) | Change in Taste as Measured by a Taste Change Questionnaire | Week 24 | 8.3 units on a scale | Standard Deviation 0.5 |
Olfactory Changes as Measured by the Smell Identification Test (SIT)
The SIT is a 50-item multiple-choice standardized test of olfactory function. Scoring of the test in the ability to smell ranges from normal (Normosmia: score 35 - 40 Women; 34 - 40 Men); to inability to smell (Anosmia score 6 - 18); or Malingering (not engaged in the test) ranges 0 - 5.
Time frame: Screening, weeks 12, 24, 36, 48 and 51
Population: Of 91 subjects in the Safety Population, data was available for 62 subjects at screening.
