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

MeasureTime frameDescription
Olfactory Changes as Measured by the Smell Identification Test (SIT)Screening, weeks 12, 24, 36, 48 and 51The 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 51Change 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 QuestionnaireWeeks 12, 24Change 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.
