Study Details

Study Description

Brief Summary

This Phase 3, multicenter, open-label study of chronic, intermittent use of study drug (DBF) is designed to evaluate the safety and tolerability of the buccal formulation of diazepam in children, adolescents and adults with intermittent, stereotypic episodes of frequent seizure activity (eg, seizure clusters) that are distinct from the subject's usual seizure pattern.

Condition or Disease Intervention/Treatment Phase
  • Drug: Diazepam Buccal Soluble Film 5, 7.5,10, 12.5,15 or 17.5 mg with individual dose determined according to age and weight category
Phase 3

Detailed Description

The Primary objective of the study is to assess the safety and tolerability of DBF (study drug) administered a minimum of 3 times to subjects with epilepsy for the treatment of seizures over a minimum 6-month period.

Secondary objectives:
  • To evaluate the usability of study drug as assessed by the ability of caregivers/subjects to administer study drug based on the Instructions for Use (IFU).

  • To evaluate the Quality of Life (QoL) of the subjects during the study drug treatment period as assessed by use of age-appropriate epilepsy scales over a minimum 6-month period.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Subjects with Epilepsy

Male or female subjects between the ages of 2 and 65 years who had an established diagnosis of epilepsy exhibited by motor seizures with clear alteration of awareness, and while on a regimen of anti-epileptic medication(s), still experienced bouts of seizures (frequent breakthrough seizures, eg, seizure clusters) and who, in the opinion of the Investigator, could need benzodiazepine intervention for seizure control at least 1 time a month on average. Subjects must have been on at least 1 concomitant anti-epileptic drug at screening.

Drug: Diazepam Buccal Soluble Film 5, 7.5,10, 12.5,15 or 17.5 mg with individual dose determined according to age and weight category
The subjects in this study administered DBF themselves or with the help of a caregiver, (trained by the study site staff in study drug administration and documentation) in the same setting as they typically used the diazepam rectal gel or other rescue medication, without the presence of study staff.
