Clobazam Use in Epilepsia Partialis Continua - Pilot Study

May 3, 2018 updated by: The Cooper Health System

A Phase III, Randomized, Open Label, Single Center, Study on the Effects of Treatment of Epilepsia Partialis Continua With Clobazam Compared to Treatment With or in Addition to Lorazepam and/or Clonazepam

The purpose of this study is to evaluate whether clobazam, brand name Onf®, is more effective as an adjunctive or monotherapy in terminating Epilepsia Partialis Continua (EPC) than either lorazepam and/or clonazepam.

Detailed Description

First approved in the United States in 2011 for use in treating Lennox-Gastaut syndrome, clobazam is the only 1, 5-benzodiazepine that is currently approved for clinical use in the United States. In previous clinical trials clobazam has been shown to have a greater efficacy and produce fewer side effects in individuals when it's adverse event profile is compared to the traditional 1,4-benzodiazepines such as diazepam, lorazepam, and clonazepam. As a benzodiazepine, clobazam has been found to have anticonvulsant properties, and structural differences as a 1,5-benzodiazepines that appear to have a broader spectrum of anticonvulsant activity than those found in 1,4-benzodiazepines. In previous reports, clobazam has been seen to be effective in ether terminating or reducing both EPC in particular and partial status epilepticus.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Clobazam
Subjects who are assigned the clobazam treatment group will receive a 10mg loading dose followed by a maintenance dose of 5-25 mg bid starting 12 hrs after the loading dose. If subjects are found to have failed to respond to treatment with clobazam, the physician investigator has the ability to either start another AED or increase the dose of clobazam depending on the clinical situation. Subjects still being treated with clobazam at discharge will be given a 30 day supply of clobazam.

Subjects who are assigned to the clonazepam treatment group will receive a dose of 1-2mg clonazepam dose tid. Following the initial treatment if a physician investigator determines that the subject's treatment has failed, the investigator has the option of treating the subject with clobazam at which point the individuals would be treated in the same method as those originally assigned to the clobazam treatment group.
