About this study

Official title: An Open-Label, Safety and Tolerability Study of Chronic Intermittent Use of Diazepam Buccal Film (DBF) in Pediatric, Adolescent and Adult Subjects With Epilepsy

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.

Read the 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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Diazepam Buccal Soluble Film 5, 7.5,10, 12.5,15 or 17.5 mg with individual dose determined according to age and weight categoryDrug

    Also called DBF, Diazepam Buccal Film (Aquestive Therapeutics)

    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.

Study groups in NCT03428360
Study groupRoleWhat they receive
Subjects with EpilepsyExperimentalMale 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.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 5 Aug 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 5 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Subjects in the Safety Analysis Set With at Least 1 Treatment-emergent Adverse Event (TEAE) (time frame: Adverse events (AEs) were recorded from Day 1 through the last study contact (Month 7 telephone contact).). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Aug 2021.
