About this study

Official title: Randomized, Double-blind Placebo Controlled Trial With Topiramate for the Treatment of Obese Patients With Binge Eating Disorder

The purpose of this study is to evaluate the effectiveness and tolerability of topiramate compared to placebo in patients with binge eating disorder receiving Cognitive Behavior Therapy (CBT)

Read the detailed description

This was a 21-week multicenter, double-blind, parallel-group, randomized controlled trial comparing the efficacy and tolerability of an add-on treatment with 200mg of topiramate versus placebo in obese patients with BED receiving group CBT. The aim of this trial is to investigate the efficacy and tolerability of adjunctive topiramate to CBT in obese patients with BED through improvement in binge eating, related psychopathology, and weight loss. The study hypothesis is that the patients using topiramate + CBT will loose more weight than patients using placebo + CBT.Tolerability will be investigated through reported adverse events and dropouts, with reasons for leaving the study being analyzed. The randomized patients will receive capsules of topiramate (25 mg, 50 mg) or placebo correspondent daily for 21 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing topiramate in people with Binge Eating, run by Janssen-Cilag Farmaceutica Ltda..

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 3 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 31 Jan 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?

Weight, Body Mass Index,number of binge eating and anthropometric measurements. 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 NCT00307619, 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 31 Jan 2011.
