About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled, Parallel-Group, Multicenter Study to Evaluate the Efficacy, Safety, and Tolerability of RWJ 333369 as Adjunctive Therapy in Subjects With Partial Onset Seizures Followed by an Open-Label Extension Study: Open-Label Extension Period
The purpose of this open-label extension study is to demonstrate that RWJ-333369 is safe as long-term add-on treatment of partial onset seizures.
Read the detailed description
333369EPY3004 is the open-label extension study that follows the double-blind studies 333369EPY3001 and 333369EPY3002 (NCT00425282 and NCT00433667, respectively). In an open label study such as 333369EPY3004, both the physician and the patient know the name of the assigned study medication. In a double blind study such as 333369EPY3001 and 333369EPY3002, neither the physician nor the patient knows the name of the assigned study medication. Patients who complete the double-blind treatment phase of studies 333369EPY3001 and 333369EPY3002 will be eligible to enter the open-label extension study 333369EPY3004 during which patients will transition through a blinded period to an open-label period with carisbamate (also referred to as RWJ-333369). There will be a blinded transition during which patients will take blinded study medication; after this, patients will then take unblinded, open-label study medication. No patients will receive placebo during the open-label extension. 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. A Quality of Life in Epilepsy questionnaire will be administered during the study. There is no statistical testing hypothesis for this study. Detailed Description update,5 Oct 2009. The Sponsor in conjunction with the DSMB agreed to amend the protocol to withdraw patients who develop signs of a drug hypersensitivity reaction. Open-label treatment with carisbamate 400 mg/day (up to a maximum of 1200mg/day) given in 2 equally divided doses BID for up to 1 year; study drug should be swallowed whole and not be chewed, divided, crushed, or dissolved.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing carisbamate in people with Epilepsy and Complex Partial Seizures, 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 1 inclusion and 6 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?
Worsening of seizures, including rates of status epilepticus. (time frame: Up to approximately 48 months). 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.
