What is being measured

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

  1. Decreases body weight; prevention of weight regain; safety and tolerability

    Measured: 2 Years

Secondary outcomes (1)
  1. Decreases waist circumference, decreases the proportion of patients with metabolic syndrome, decreases triglycerides, decreases non-HDL-C, decreases LDL-C, decreases fasting insulin, decreases FPG; increases HDL-C, increases insulin sensitivity

    Measured: 2 Years

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Comparator: taranabant in people with Obesity, run by Merck Sharp & Dohme LLC.

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: stopped early, as of the sponsor's last update on 3 Apr 2015. 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. Some participants in this study may receive a placebo. 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 was stopped early (reason given: The overall profile does not support development for obesity). Results are not available in the source record.

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?

Decreases body weight; prevention of weight regain; safety and tolerability (time frame: 2 Years). 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 3 Apr 2015.
