Method-of-Use Study Assessing the Effect of Naltrexone Sustained Release (SR)/ Bupropion SR on Body Weight and Cardiovascular Risk Factors in Overweight and Obese Subjects

November 30, 2015 updated by: Orexigen Therapeutics, Inc

A Multicenter, Randomized, Open-Label, Controlled, Method-of-Use Study Assessing the Effect of Naltrexone Sustained Release (SR)/Bupropion SR on Body Weight and Cardiovascular Risk Factors in Overweight and Obese Subjects (The Ignite Study)

The purpose of this Phase 3b study is to assess the effects of combination therapy with naltrexone SR/bupropion SR (NB) used in conjunction with a comprehensive lifestyle intervention (CLI) and in a manner consistent with its intended use after marketing approval, on body weight and cardiovascular risk factors compared to the effects of Usual Care in subjects who are overweight with dyslipidemia and/or controlled hypertension or obese. Subjects in the NB and CLI group are required to undergo an evaluation to continue treatment at Week 16. Subjects are to be discontinued from full participation if they do not lose at least 5% of their body weight relative to baseline and/or are experiencing sustained increases in blood pressure (systolic or diastolic) of ≥10 mmHg above baseline. At Week 26, subjects originally assigned to Usual Care switch to treatment with NB and CLI, and subjects assigned to NB and CLI continue treatment for the duration of the study (78-weeks treatment period).

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA).

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
