About this study
Official title: A Double-Blind, Placebo-Controlled, Dose-Titration Study to Determine Safety, Tolerability and Preliminary Efficacy of RWJ-333369 as Adjunctive Therapy in Subjects With Treatment-Resistant Partial Seizures (With or Without Secondary Generalization) or Primarily Generalized Tonic-Clonic Seizures
The purpose of this study is to evaluate the safety and preliminary effectiveness of the novel compound RWJ-333369 in patients with partial onset seizures who are currently being treated with 1 or 2 concomitant antiepileptic drugs.
Read the detailed description
333369EPY2002 is the open-label extension study that follows the double-blind study 333369EPY2001. In an open label study such as 333369EPY2002, both the physician and the patient know the name of the assigned study medication. In a double blind study such as 333369EPY2001, neither the physician nor the patient knows the name of the assigned study medication. Patients who complete the double-blind treatment phase of study 333369EPY2001 will be eligible to enter the open-label extension study during which patients will transition through a blinded period to an open-label period with carisbamate (also referred to as RWJ-333369). RWJ-333369 is a new chemical compound with anticonvulsant activity that is currently under investigation as a treatment for epilepsy. Patients electing to enter the open-label extension phase will be supplied with both open-label carisbamate (RWJ-333369) and blinded study medication for the transition phase. During this transition phase (up to 21 days in length), the patient's dose of double-blind study drug will be gradually reduced and stopped and treatment with open-label RWJ-333369 will be started. Throughout the remainder of the open label extension phase, investigators will be allowed to make further adjustments of the dosage and schedule of carisbamate, including independent adjustment of the morning and evening doses, but a dosage of 1,200 mg/day may not be exceeded and increases in dosage must be in increments of no more than 200 mg/day. Patients who, in the judgment of the investigator, continue to benefit from treatment with RWJ-333369 may continue to receive the drug with follow up clinic visits every 3 months until RWJ 333369 is available by prescription or the program is terminated by the sponsor. Initial dose RWJ-333369 is 1 capsule (250 milligram (mg) taken twice daily. Dosage may be changed at weekly intervals. The maximum permitted dose will be 4 capsules (1000 mg), twice daily during dose titration. Double blind-treatment duration is up to 71 days with the option to continue treatment in an open-label study. Maximum dose in open-label study is 1200 mg/day

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing RWJ 333369: in people with Epilepsy and Epilepsies, 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 1 inclusion and 5 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 24 Jan 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Adverse events as a measure of safety and tolerability (time frame: At followup visits every 3 months up to the time RWJ-333369 is available by prescription or study is terminated by sponsor). 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 24 Jan 2013.
