About this study
Official title: TOPAMAX (Topiramate) Monotherapy Comparison Trial to Standard Monotherapy in the Treatment of Newly Diagnosed Epilepsy (RWJ-17021-000); Phase IIIB
The purpose of this study is to compare the effectiveness and safety of topiramate to standard antiepileptic drugs in children and adults with newly diagnosed epilepsy.
Read the detailed description
Topiramate is a drug that is currently widely used for the treatment of seizures in adults and pediatric patients (2 to 16 years of age). This is a randomized, double-blind, parallel-group study to evaluate the effectiveness and safety of two dosages of topiramate (100 or 200mg per day) compared with standard antiepileptic drugs (carbamazepine or valproate) in patients with newly diagnosed epilepsy. The study is composed of three phases: baseline (up to 7 days), double-blind treatment, and a blinded extension. The double-blind phase is divided into two periods: titration, in which the dose of drug is gradually increased (approximately 35 days), and stabilization (of variable duration, with regular scheduled visits up to 92 days and then every 3 months thereafter). The dose of study drug remains constant during the stabilization period. In the blinded extension, patients completing the double blind phase are given the opportunity to take the other study medication in a blinded fashion (patient unaware of identity of the drug). This phase continues until the patient leaves the study or the data base for the double blind phase is finalized. The primary assessment of effectiveness is the time to first seizure from Day 15 of the study. Safety assessments include the frequency of adverse events during the study, results of clinical laboratory tests (hematology and biochemistry), measurements of vital signs and body weight, and physical examination findings. The study hypothesis is that the 200mg dose of topiramate is superior to the 100mg dose in delaying the time to first seizure and is well-tolerated. Oral topiramate (25milligram [mg] or 50mg capsules or tablets),starting at 25mg/day (Week 1),increasing to 100mg or 200mg/day (Week 5).Increasing carbamazepine to 600mg/day or valproate to 1250mg/day (Week 5).Maximum dosages continue for a variable time and then taper over 4 weeks to starting dose.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Topiramate; Carbamazepine; Valproate in people with Epilepsy and Seizures, run by Johnson & Johnson Pharmaceutical Research & Development, L.L.C..
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 4 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 8 Jun 2011. 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?
Time to first seizure from Day 15 of the study. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00236717, which also lists 1 linked publication.
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 8 Jun 2011.
