About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Study to Evaluate the Efficacy and Safety of Topiramate for the Prophylaxis of Migraine in Pediatric Subjects 12 to 17 Years of Age

The primary purpose of this study is to evaluate the effectiveness and safety of topiramate compared with placebo in the prevention of migraine attacks in children (12 to 17 years of age).

Read the detailed description

This is an outpatient, randomized, double-blind, placebo-controlled study to evaluate the effectiveness of 2 dosages of topiramate (50 and 100 milligrams/day) compared with placebo in the prevention of migraine attacks in children 12 to 17 years of age. The study is composed of 3 phases: pretreatment, double-blind treatment for 4 months (16 weeks), and posttreatment. During the study, patients will maintain headache and medication records to document the following: occurrence and duration of headaches; severity of headache pain; whether or not the headache is pulsating or aggravated by physical activity; associated symptoms, such as nausea, vomiting, photophobia, phonophobia, abdominal pain; and medication taken to relieve headache pain or symptoms. Assessment of efficacy include the percent reduction in the frequency of monthly migraine attacks over the last 12 weeks of the double-blind treatment phase compared with prospective BL period. In addition, the percent reduction in (a) average monthly migraine days, (b) average monthly headache days, and (c) monthly migraine rate, over the last 12 weeks of the double-blind treatment phase compared with the pretreatment phase will be assessed. Safety assessments include the incidence of adverse events, measurement of vital signs (pulse, blood pressure, oral temperature), results of pregnancy tests, physical and neurologic examinations, clinical laboratory tests (hematology, biochemistry, and urinalysis), and monitoring for visual or ocular disturbances, heat intolerance, renal or urinary disturbance, depression and rash. The study hypothesis is that the percent reduction in frequency of monthly (28-day) migraine attacks (using the 48-hour rule) from the prospective baseline period (pretreatment phase) to the last 12 weeks of the double-blind phase will be significantly better for the topiramate groups than for the placebo group. Topiramate tablets (25 milligrams) or placebo, beginning at 25mg once daily (Week 1), increasing to twice daily total of 50mg or 100mg (Week 4). Maximum dosage of topiramate (or placebo) continues for next 12 weeks. Dosage may be reduced once at investigator's discretion.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study of Migraine and Vascular Headaches, 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 4 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?

Percent reduction in the frequency of monthly migraine attacks (using 48-hour rule) over the last 12 weeks of the double-blind treatment phase compared with the 4-week prospective baseline period.. 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 8 Jun 2011.
