clonazepam and Baltic Myoclonic Epilepsy

clonazepam has been researched along with Baltic Myoclonic Epilepsy in 2 studies

Clonazepam: An anticonvulsant used for several types of seizures, including myotonic or atonic seizures, photosensitive epilepsy, and absence seizures, although tolerance may develop. It is seldom effective in generalized tonic-clonic or partial seizures. The mechanism of action appears to involve the enhancement of GAMMA-AMINOBUTYRIC ACID receptor responses.
clonazepam : 1,3-Dihydro-2H-1,4-benzodiazepin-2-one in which the hydrogens at positions 5 and 7 are substituted by 2-chlorophenyl and nitro groups, respectively. It is used in the treatment of all types of epilepsy and seizures, as well as myoclonus and associated abnormal movements, and panic disorders. However, its use can be limited by the development of tolerance and by sedation.

Trial Outcomes

Percent Change From Baseline to the End of Treatment Period on the Action Myoclonus Score (Unified Myoclonus Rating Scale (UMRS) Section 4)

The range for Action Myoclonus Score (centrally read) is 0 (best) - 160 (worst). Percent change from Baseline = 100 X ((Baseline UMRS4 - Treatment UMRS4) / Baseline UMRS4). Baseline is defined as the last non-missing value prior to or on Randomization Visit. (NCT00368251)
Timeframe: From Baseline to End of Treatment Period (Week 14 or Early Discontinuation Visit)

InterventionPercent change (Median)

Percent Change From Baseline to the End of Treatment Period on the Functional Disability Score (Unified Myoclonus Rating Scale (UMRS) Section 5)

The range for Functional Disability Score is 0 (best) to 28 (worst). Percent change from Baseline = 100 X ((Baseline UMRS5 - Treatment UMRS5) / Baseline UMRS5). Baseline is defined as the last non-missing value prior to or on Randomization Visit. (NCT00368251)

Percent Change From Baseline to the End of Treatment Period on the Myoclonus Patient Questionnaire (Unified Myoclonus Rating Scale (UMRS) Section 1)

The range for Myoclonus Patient Questionnaire is 0 (best) to 44 (worst). Percent change from Baseline = 100 X ((Baseline UMRS1 - Treatment UMRS1) / Baseline UMRS1). Baseline is defined as the last non-missing value prior to or on Randomization Visit. (NCT00368251)

Percent Change From Baseline to the End of Treatment Period on the Stimulus Sensitivity Score (Unified Myoclonus Rating Scale (UMRS) Section 3)

The range for Stimulus Sensitivity Score is 0 (best) to 17 (worst). Percent change from Baseline = 100 X ((Baseline UMRS3 - Treatment UMRS3) / Baseline UMRS3). Baseline is defined as the last non-missing value prior to or on Randomization Visit. (NCT00368251)
