About this study

Official title: The Safety and Efficacy of Topiramate in Male Patients With Abdominal Obesity: A 6-Month Double-Blind, Randomized, Placebo-Controlled Study With a 6-Month Open-Label Extension

The purposes of this study are to compare the effects of Topiramate and placebo on abdominal visceral fat accumulation at 6 months and to evaluate the safety of Topiramate for up to 12 months of continued treatment in male patients with abdominal obesity.

Read the detailed description

Topiramate is not approved for the treatment of obesity. This study is a 6-month randomized, double-blind placebo-controlled study, followed by a 6-month open-label extension study to evaluate the effect of Topiramate on abdominal visceral fat accumulation, a clinical surrogate known to be associated with the complications of obesity such as increased incidence of Type 2 diabetes mellitus, hypertension, and dyslipidemia, and their associated morbidities. Patients will be randomized to receive either daily Topiramate or placebo. Effectiveness will be measured by multiple parameters such as abdominal visceral fat (assessed by computed tomography), total and subcutaneous abdominal fat, body composition, body weight, body mass index, glucose tolerance, lipid profile, blood pressure, Topiramate plasma concentration, or 24 hours energy expenditure (selected patients). Safety evaluation (adverse events, vital signs, 12-lead ECG, clinical laboratory tests) will be conducted throughout the study. The study hypothesis is that Topiramate is effective in reducing abdominal visceral fat in male patients and well tolerated. After the initial 12-week titration phase, patients will receive either Topiramate (200mg twice daily or the maximum dose tolerated) or placebo by mouth for 6-months. Then, patients will receive Topiramate (200mg twice daily or the maximum tolerated dose) for 6-months during the open-label phase.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The mean change from baseline to Month 6 in abdominal visceral fat as assessed by computed tomography; the safety of Topiramate for up to 12 months of continued treatment in male subjects with abdominal obesity.

Secondary outcomes (1)
  1. Mean change and percent change in body weight, and mean change in total abdominal fat, subcutaneous abdominal fat, body composition, and body mass index from baseline to Month 6.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing topiramate in people with Obesity, 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 6 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 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 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?

The mean change from baseline to Month 6 in abdominal visceral fat as assessed by computed tomography; the safety of Topiramate for up to 12 months of continued treatment in male subjects with abdominal obesity.. 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.
