flumazenil and Benign Frontal Childhood Epilepsy

flumazenil has been researched along with Benign Frontal Childhood Epilepsy in 10 studies

Flumazenil: A potent benzodiazepine receptor antagonist. Since it reverses the sedative and other actions of benzodiazepines, it has been suggested as an antidote to benzodiazepine overdoses.
flumazenil : An organic heterotricyclic compound that is 5,6-dihydro-4H-imidazo[1,5-a][1,4]benzodiazepine which is substituted at positions 3, 5, 6, and 8 by ethoxycarbonyl, methyl, oxo, and fluoro groups, respectively. It is used as an antidote to benzodiazepine overdose.

Change From Baseline of TMS Measurement of Intracortical Facilitation at the End of the Study Drug and Placebo Treatment Periods

Transcranial Magnetic Stimulation (TMS) is a non-invasive technique which applies magnetic pulses to the brain via a coil inducing an electrical current in the brain. Stimulation is typically applied at a sufficient intensity to trigger action potentials in nearby neurons. Intracortical facilitation (ICF) and inhibition (ICI) were studied using a paired stimulus paradigm. The motor threshold (MT) was first established. The conditioning stimulus (70% MT) followed by the test stimulus (120% MT) was delivered at an interstimulus interval (ISI) of 10 ms for ICF. Each run consisted of 10 trials, and the amplitude ratio of the mean conditioned Motor Evoked Potential (MEP) to control MEP was determined. A larger amplitude ratio indicates greater cortical excitability. The differences between Placebo and Baseline, and SGS and Baseline were obtained. These values were averaged across individuals to report a mean. (NCT02019667)
Timeframe: Baseline and Six months

Change From Baseline of TMS Measurement of Long Interval Intracortical Inhibition (Long ICI) at the End of the Study Drug and Placebo Treatment Periods

Transcranial Magnetic Stimulation (TMS) is a non-invasive technique which applies magnetic pulses to the brain via a coil inducing an electrical current in the brain. Stimulation is typically applied at a sufficient intensity to trigger action potentials in nearby neurons.Intracortical facilitation and inhibition were studied using a paired stimulus paradigm. The motor threshold (MT) was first established. The conditioning stimulus (70% MT) followed by the test stimulus (120% MT) was delivered at 100 ms for long ICI. Each run consisted of 10 trials, and the amplitude ratio of the mean conditioned Motor Evoked Potential (MEP) to control MEP was determined. A larger amplitude ratio indicates greater cortical excitability. The differences between Placebo and Baseline, and SGS and Baseline were obtained. These values were averaged across individuals to report a mean. (NCT02019667)

Change From Baseline of TMS Measurement of Motor Threshold at the End of the Study Drug and Placebo Treatment Periods

Transcranial Magnetic Stimulation (TMS) is a non-invasive technique which applies magnetic pulses to the brain via a coil inducing an electrical current in the brain. Stimulation is typically applied at a sufficient intensity to trigger action potentials in nearby neurons. The motor threshold is defined as the minimum percentage of the stimulator output that evoked a motor evoked potential of more than 50µV in at least 5 out of 10 trials. Motor threshold was measured at the end of the study drug period and the end of the Placebo period. The differences between Placebo and Baseline, and SGS and Baseline were obtained. A decrease from baseline value indicates increased cortical excitability and an increase from baseline value indicates reduced cortical excitability. These values were averaged across individuals to report a mean and standard deviation of this baseline-to-treatment period change. The mean for each treatment can be compared to have a baseline-adjusted treatment effect. (NCT02019667)
Timeframe: Baseline and Six months

Change From Baseline of TMS Measurement of Short Interval Intracortical Inhibition (Short ICI) at the End of the Study Drug and Placebo Treatment Periods

Transcranial Magnetic Stimulation (TMS) is a non-invasive technique which applies magnetic pulses to the brain via a coil inducing an electrical current in the brain. Stimulation is typically applied at a sufficient intensity to trigger action potentials in nearby neurons. Intracortical facilitation and inhibition were studied using a paired stimulus paradigm. The motor threshold (MT) was first established. The conditioning stimulus (70% MT) followed by the test stimulus (120% MT) was delivered at an interstimulus interval (ISI) of 2 ms for short ICI. Each run consisted of 10 trials, and the amplitude ratio of the mean conditioned Motor Evoked Potential (MEP) to control MEP was determined. A larger amplitude ratio indicates greater cortical excitability. The differences between Placebo and Baseline, and SGS and Baseline were obtained. These values were averaged across individuals to report a mean. (NCT02019667)
Timeframe: Baseline and Six months

Change From Baseline on the Adaptive Behavior Assessment System (ABAS) Test at the End of the Study Drug and Placebo Treatment Periods

The ABAS questionnaire was completed by the participant's parent or caregiver at the end of each six month treatment period.The ABAS provides a comprehensive picture of adaptive skills across the lifespan. The questionnaire addresses Conceptual, Social and Practical skills including communication, self-direction, use of leisure time, health, safety and self-care. The General Adaptive Composite score ranges from <40 to >160 with a lower score representing lower adaptive behavior. The difference between Placebo and Baseline and Study Drug and Baseline were obtained. These values were averaged across individuals to report a mean and a standard deviation of the baseline-to-treatment period change. The means for each treatment can be compared to have a baseline-adjusted treatment effect interpretation. A positive change represents an improvement in adaptive skills compared with baseline and a negative change represents a decline in adaptive skills compared with baseline. (NCT02019667)
Timeframe: baseline and six months

Results of Physical Examination at the End of the Study Drug and Placebo Treatment Periods

A physical examination was administered by a physician to subjects at the end of each six month treatment period, i.e., following completion of a six month period on SGS-742 or Placebo. Results of the examination ranged from 0-4 with scores defined as follows: 0=No observation; 1=Stable baseline findings; 2=New asymptomatic finding; 3=Patient reports some worsening of a baseline daily function associated with new finding; 4=Patient unable to carry out a baseline daily function associated with new finding (NCT02019667)
