About this study

Official title: The Open Label Extension Portion of the Study Entitled A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study to Evaluate the Efficacy, Safety, and Tolerability of Carisbamate as Adjunctive Therapy in Subjects With Partial Onset Seizures.

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.

Read the detailed 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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety will be evaluated by 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

    Measured: after a stable dose of Carisbamate is achieved, study visits to assess safety will be every three months for the duration of the subject's participation; subjects will also maintain a seizure count diary

Secondary outcomes (1)
  1. To evaluate the impact of carisbamate on subject functioning and well being using the QOLIE-31 Patient Inventory (as exploratory). Administered at month 3 and end of study.

    Measured: after a stable dose of Carisbamate is achieved, study visits to assess safety will be every three months for the duration of the subject's participation; subjects will also maintain a seizure count diary

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing carisbamate in people with Epilepsy, Partial, Motor and Epilepsy, Complex Partial, run by SK Life Science, Inc..

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 5 inclusion and 1 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 18 Jun 2013. Status can change between updates, so confirm with the study contact before making plans.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Safety will be evaluated by 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 (time frame: after a stable dose of Carisbamate is achieved, study visits to assess safety will be every three months for the duration of the subject's participation; subjects will also maintain a seizure count diary). 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 18 Jun 2013.
