Clinical Trial Summary

The purpose of this study is to obtain long-term safety and tolerability information on carisbamate as add-on therapy for the treatment of partial onset seizures in patients with epilepsy. Seizure counts will be obtained to measure the rate of seizures for each patient during the study.


Clinical Trial Description

CARISEPY3014 is the open-label extension study that follows the double-blind study CARISEPY3013 (NCT00740623). In an open label study such as CARISEPY3014, both the physician and the patient know the name of the assigned study medication. In a double blind study such as CARISEPY-3013, neither the physician nor the patient knows the name of the assigned study medication. Patients who complete the 14-week double-blind treatment phase of study CARISEPY3013 will be eligible to enter the open-label extension study during which patients will transition through a 1-week blinded period to open-label carisbamate. There will be a 1 week blinded transition during which patients will take blinded study medication; after this, patients will then take unblinded, open-label study medication. Safety assessments include the monitoring of the frequency, severity, and timing of adverse events, clinical laboratory test results, 12-lead electrocardiogram (ECG) recordings, vital signs measurements, physical and neurologic examinations, the Physician Withdrawal Checklist for symptoms of withdrawal for those patients who taper and/or discontinue study drug, and pregnancy tests for females of childbearing potential. Seizure counts will be obtained at every visit. The Quality of Life in Epilepsy-31 Patient Inventory questionnaire will be administered once during the study. A Medical Resource utilization questionnaire will be used to obtain cost-effectiveness information on carisbamate and will be administered twice during the study. There is no statistical testing hypothesis for this study. Carisbamate tablets taken twice daily in 2 equally divided doses, with or without food, and taken with noncarbonated water. During the first week on study, patients will take blinded transition study medication and thereafter will take a target dosage of 800 mg/day of unblinded, open-label study medication. The dosage of study medication will range from 400 to 1,200 mg/day. Patients will receive treatment for 1 year with the potential to receive treatment longer. ;
